Iran’s Biodiversity and Current Threats Explained

Editor’s Note: Why We Are Featuring Iran Now

Iran is once again dominating headlines.

From widespread public demonstrations that surged across Iran in late 2025 into early this year, to the current escalation and the breaking of war, the country is being discussed globally in the context of politics, conflict, and human suffering. The loss of life and instability unfolding are real and devastating. Nothing in this feature is intended to diminish that reality.

But there is something else that often goes unspoken.

For years, inside and outside of environmental circles, people have quietly asked me a question. Sometimes with curiosity. Sometimes with hesitation. Sometimes almost with guilt.

“What is actually there?”

They were referring to biodiversity.

In today’s world, there is pressure to already know. When the breadth of human knowledge appears to sit at our fingertips, asking basic questions can feel uncomfortable. If a place overlaps with your professional field or your moral concern, you are expected to understand it fully.

Curiosity, however, should never carry shame.

At SEVENSEAS Media, we see questions as bridges. When a region becomes defined only by conflict, it becomes even more important to remember that it is also defined by landscapes, species, ecosystems, culture, and people who have lived in relationship with nature for millennia.

Iran is not only a geopolitical flashpoint. It is a country of vast mountain ranges, ancient forests, wetlands, deserts, coral communities, migratory flyways, and one of the most strategically significant marine corridors in the world. It sits at the intersection of terrestrial and marine biodiversity, connecting ecosystems across Central Asia, the Caucasus, the Arabian Peninsula, and the Indian Ocean.

It is home to coastal communities whose fishing traditions stretch back centuries, to wetlands that host migratory birds crossing continents, and to marine systems that sustain life far beyond their shorelines.

This feature has been in development for some time. In light of current events, we believe it is important to move forward thoughtfully and with care.

Education is not a distraction from suffering. It is part of long term resilience.

At SEVENSEAS Media, we promote education and peace across cultures and living in harmony with nature. We believe that understanding biodiversity can humanize places that are otherwise reduced to headlines. Conservation, at its best, transcends politics and builds shared responsibility for the natural world.

In the articles that follow, we explore the geography of Iran, its terrestrial biodiversity, its migratory importance, and its ocean and coastal ecosystems. We touch on traditional fishing cultures, current pressures, conservation challenges, and the organizations working to protect what remains.

As always, we are not here to simplify complexity. We are here to make space for informed curiosity and careful understanding.

In moments of conflict, it can feel easier to look away. We choose instead to look closer, and to recognize that ecological systems persist regardless of political borders.

Iran sits at the center of a fast moving regional war that has already spilled into the maritime domain. Attacks affecting commercial shipping, electronic interference with navigation signals, and heightened risk to seafarers, alongside international warnings, diplomatic activity, and emergency maritime guidance addressing commercial shipping safety. This article is not about the conflict itself, but to write about Iranian coastal ecosystems we must acknowledge the immediate reality that the Persian Gulf and the Gulf of Oman are currently under exceptional strain, and that ecological harm can escalate quickly when navigation, port operations, and safety at sea are compromised.

That is precisely why biodiversity deserves attention now. Iran’s living landscapes, from ancient temperate forests to mangrove channels and coral communities, are not a side story. They are the fabric that sustains food systems, coastal livelihoods, and cultural identity. They are also a record of resilience in a region where climate stress, water scarcity, and rapid coastal development have been reshaping ecosystems for decades.

Iran’s total area is often cited at roughly 1.65 million square kilometers, with the World Bank reporting land area of 1,622,500 square kilometers for 2023. The country spans sharp ecological gradients: the Caspian coast in the north, the Zagros and Alborz mountain systems, arid interior plateaus, and two very different southern marine frontiers, the Persian Gulf and the Gulf of Oman. This geographic spread helps explain why Iran features prominently in national and international biodiversity planning, and why conservation challenges vary so dramatically across regions. Iran’s national biodiversity strategy and action plan, submitted under the Convention on Biological Diversity, lays out the country’s own framing of pressures and priorities, from habitat loss and water stress to the need for stronger monitoring and management capacity.

Protected areas offer one useful, if imperfect, lens on how much land is being set aside for nature. Using a standardized indicator based on the World Database on Protected Areas, the World Bank reports terrestrial protected areas at about 8.6 percent of Iran’s land area in 2024. On paper, that number may sound substantial. On the ground, protection effectiveness depends on funding, enforcement, and community legitimacy, and those are harder variables to measure, especially during periods of economic constraint and heightened political tension.

To understand Iran’s coastal biodiversity, it helps to start with two pieces of context that sit inland but shape the seas. The first is the northern forest belt. The Hyrcanian Forests, inscribed as a UNESCO World Heritage site, represent a rare temperate broadleaf forest system with deep evolutionary history and high plant diversity. UNESCO notes the antiquity of these forests and documents thousands of vascular plant species, along with significant bird and mammal richness. Forest integrity matters for the coast because watersheds and rivers regulate sediment, nutrients, and pollutants that end up in deltas, lagoons, and nearshore nurseries.

The second is migratory biodiversity, which is tightly linked to wetlands. Iran is one of the countries most closely associated with the Ramsar Convention on Wetlands, which was adopted in the Iranian city of Ramsar in 1971. Iran’s country profile under Ramsar lists 27 Ramsar sites covering 1,494,371 hectares. These wetlands are not only local biodiversity reservoirs, they are stepping stones for migratory birds across Eurasia, and they connect inland water decisions to coastal fisheries and estuarine health.

Wetlands also reveal how biodiversity can unravel when hydrology collapses. Lake Urmia, once among the world’s great hypersaline lakes, has experienced severe drying over recent decades. A 2024 peer reviewed study in Bird Conservation International documents major consequences for waterbird assemblages, linking long term ecological change to declining water availability and rising salinity conditions. This inland story matters for a marine and coastal article because it illustrates a broader theme across Iran and the wider region: biodiversity is often limited less by what species could live there, and more by whether water, habitat connectivity, and governance can sustain them.

Southern seas and coastal habitats

Iran’s southern coastline stretches along two connected but ecologically distinct marine systems. The Persian Gulf is shallow and naturally extreme, with high salinity and large seasonal temperature swings. These conditions shape everything from coral survival thresholds to fish distribution, and they amplify the stakes of climate warming. The Gulf of Oman, opening toward the Arabian Sea, is more oceanic, with deeper waters and different circulation patterns, and it links Iran’s coast to broader Indian Ocean dynamics.

Across both southern seas, four habitat types carry disproportionate weight for biodiversity and fisheries productivity: mangroves, seagrass meadows, coral communities, and intertidal flats and estuaries. When these habitats are intact and connected, they function as nurseries and feeding grounds that support coastal fish, invertebrates, birds, and megafauna. When they are fragmented, the loss cascades through food webs and into human livelihoods.

Mangroves are the clearest example of a habitat that concentrates biodiversity and also concentrates human dependence. A widely cited scientific overview of Iranian mangrove ecosystems, published in Acta Ecologica Sinica, synthesizes where mangroves occur along Iran’s coasts and why they matter ecologically. In Iran, mangroves are strongly associated with tidal channels and deltas, and they are often dominated by Avicennia marina. Their ecological value is not simply that they are “trees by the sea.” Mangroves create structure in an otherwise shifting environment, producing sheltered water, organic matter, and microhabitats that support fish, crabs, mollusks, and juvenile stages of many species important to fisheries. They also store carbon in sediments and provide some buffering against storms and shoreline change, benefits that are increasingly relevant as climate risks intensify.

One of the most important mangrove anchored seascapes in Iran is the Hara Biosphere Reserve, recognized under UNESCO’s Man and the Biosphere Programme. UNESCO describes the reserve as located in the Mehran River delta near the Straits of Khuran, adjacent to Qeshm Island, and identifies its Avicennia mangrove ecosystem as the basis for its biodiversity significance. UNESCO’s page lists an area of 206,243 hectares. The same broader system is also recognized under Ramsar as the Khuran Straits wetland, which Ramsar describes as extensive intertidal flats, saltmarsh, mangroves, and numerous creeks and islands. These overlapping designations do not automatically guarantee protection, but they show that the area is internationally recognized for its ecological functions.

Seagrass meadows are often less visible than mangroves, but they play a similar role as nurseries and as food sources for some marine herbivores. Seagrass supports juvenile fish and invertebrates, stabilizes sediments, and can influence local water clarity. In many parts of the Persian Gulf, seagrass is also associated with marine megafauna foraging, including sea turtles. A central challenge in writing about seagrass along Iran’s coast is that long term, coastwide mapping and monitoring are less consistently accessible in the public literature than for mangroves and some coral sites. That gap matters because seagrass is highly sensitive to dredging, coastal construction, and water quality shifts, and it is easy to lose without noticing until productivity declines.

Coral communities are a third pillar of southern biodiversity. Coral reefs in the Persian Gulf exist under conditions that would be stressful for many tropical reef systems, yet they persist in multiple locations, including around islands. This makes them scientifically important as a window into resilience and limits. Recent peer reviewed work in Scientia Marina synthesized the state of coral bleaching across the Persian Gulf and highlighted how marine heatwaves and warming trends are reshaping reef health in the region. Iran’s reef communities are part of that broader story. Coral health is not only about biodiversity for its own sake. Coral structure influences fish habitat, coastal tourism value, and shoreline protection in some settings. When coral declines, the physical complexity that supports many reef associated species can erode, and recovery is often slow, especially under repeated heat stress.

Intertidal flats and estuaries are the fourth habitat type that repeatedly emerges as ecologically load bearing. Mudflats, tidal creeks, and estuarine channels support migratory birds, benthic invertebrates, and juvenile fish. They are also often the first places where pollution accumulates, and the first places where coastal engineering, dredging, and port expansion produce irreversible change.

Islands and offshore biodiversity

Iran’s southern islands concentrate biodiversity, cultural history, and development pressures in a small footprint. They also serve as focal points for conservation designations and ecological research because they can host coral communities, nesting beaches, and productive nearshore waters shaped by currents.

Qeshm Island is the most prominent example, not least because of its proximity to the mangrove systems of the Khuran Straits and the Hara Biosphere Reserve. In practical ecological terms, the island seascape is a mosaic: mangrove channels and mudflats on one side, more exposed coasts on others, and a blend of local fishing, shipping traffic, and tourism.

Several islands are also significant for sea turtles. Sheedvar Island, for example, is listed by Ramsar as a wetland site, reflecting the ecological value of the island and its surrounding marine environment. Turtle nesting in Iran is often spatially concentrated, which makes it vulnerable to localized disturbance. A peer reviewed paper in Chelonian Conservation and Biology focused on hawksbill turtle nesting and conservation conditions at Sheedvar Island, underscoring the role of specific island beaches for reproduction. When nesting habitat is limited to a small set of sites, artificial lighting, beach disturbance, and fishing related interactions can have outsized population effects.

Marine mammals are another crucial part of Iran’s coastal biodiversity, and also a window into how much remains under documented. The Indian Ocean humpback dolphin, Sousa plumbea, is among the best studied in Iranian waters, particularly around protected coastal areas. The Important Marine Mammal Area factsheet for Nakhiloo Coastal Waters describes a small resident population, notes photo identification research that documented dozens of individuals, and links the area to the Dayer Nakhiloo National Marine Park and its shallow mangrove associated waters. This kind of work matters because it moves marine mammals from anecdote to monitoring, and because it can guide practical mitigation, such as reducing bycatch risk, regulating high speed vessel traffic, and managing coastal development footprints.

Coastal life and fishing traditions

Biodiversity is not only species lists and habitat maps. It is also the daily relationship between people and the sea, especially in coastal provinces where fishing is food security, identity, and inherited knowledge.

A helpful entry point is the cultural heritage of seafaring itself. UNESCO’s documentation of the traditional skills of building and sailing Iranian lenj boats describes wooden vessels historically used for sea journeys, trade, fishing, and pearl diving, alongside navigation knowledge and weather forecasting traditions. This is not nostalgia. It is an illustration of how maritime life has long depended on reading winds, currents, seasonal cycles, and ecological cues, and how cultural systems develop around predictable patterns in marine environments.

Modern fisheries along Iran’s southern coasts are a blend of artisanal practices and more industrialized capacity, shaped by regulation, market demand, and regional competition. Some of the clearest, citable information on management measures comes from FAO linked materials. The FAO Fishery and Aquaculture Country Profile for Iran describes the country’s northern and southern coasts and provides a baseline overview of fisheries.

For a more specific and current window into gear and management, an FAO RECOFI workshop document titled Status of Fisheries in I.R. Iran includes concrete statements about trawling restrictions: it describes industrial bottom trawling as forbidden in the Persian Gulf since 1990 and in the Oman Sea since 2020, while allowing limited artisanal bottom trawling for shrimp under seasonal constraints. These details matter for biodiversity because trawling is among the fishing methods most directly linked to seabed disturbance and bycatch risk. Restrictions do not eliminate ecological impact, but they can reduce pressure, especially when paired with enforcement and gear improvements.

It is also important to recognize that fisheries culture cannot be separated from coastal economics. When livelihoods depend on catch, ecological decline becomes a household crisis, not an abstract conservation concern. That reality is one reason why data gaps are so consequential. If stock assessments are incomplete or politically constrained, decisions can drift toward short term survival rather than sustainable yields, especially during periods of inflation, sanctions, or conflict related disruption.

Strait of Hormuz and a crowded seascape

The Strait of Hormuz is one of the most geopolitically significant maritime corridors on Earth, and it is also an ecological bottleneck in a quieter sense: it concentrates shipping density, underwater noise, pollution risk, and the pathways by which non native species can move via ballast water and hull fouling.

The United States Energy Information Administration describes the Strait of Hormuz as a critical oil transit chokepoint. That framing is usually economic, but the ecological implications are direct. A high traffic corridor raises the baseline probability of incidents, from collisions to spills. It also raises chronic stressors that can be harder to see, like persistent noise that affects dolphins and other marine life, and localized contamination around ports and anchorage zones.

In the current crisis, those risks have sharply intensified. Reuters has reported disruption to shipping in and around the Strait, including tankers stranded or damaged and broader market impacts. The International Maritime Organization has issued a statement emphasizing protection of seafarers and the fundamental principle of freedom of navigation. Wired has reported a surge in GPS and AIS interference in the Gulf region since the onset of the current campaign, warning of navigation hazards that elevate collision and spill risk. These are not biodiversity sources in the usual sense, but they are essential context because acute conflict related disruptions can translate into ecological harm on very short timescales.

For readers focused on biodiversity, the key point is not to turn an ecology story into a war story. The point is to recognize that when the Strait becomes unstable, the environmental stakes rise for everyone, including coastal communities who have no control over geopolitics but live with the consequences.

Institutions and research working in and near Iran

Even under political and economic constraints, biodiversity work in Iran is not isolated. It exists at the intersection of Iranian agencies, universities, civil society, and treaty based cooperation.

At the national policy level, Iran’s biodiversity strategy and action plan submitted under the Convention on Biological Diversity lays out institutional roles and planned actions, and it serves as an anchor document for how Iran presents its biodiversity priorities internationally. This does not mean implementation is straightforward, but it provides a reference point for programs, targets, and constraints.

On wetlands, UNDP has a long running Conservation of Iranian Wetlands Project, with a public project page describing ecosystem based approaches and capacity building in partnership with national stakeholders. UNDP has also published additional material describing outcomes and methods, including work linked to agricultural water use and wetland basin management. These efforts matter for marine and coastal biodiversity because Ramsar’s definition of wetlands includes coastal systems such as estuaries and tidal flats, and because inland water decisions can shape coastal productivity.

At the regional level, the Regional Organization for the Protection of the Marine Environment, known as ROPME, is a core coordinating institution for the wider Gulf region. ROPME’s official site describes its establishment and purpose, and UNEP’s Kuwait Convention page describes ROPME’s objective to coordinate member state efforts to protect marine and coastal ecosystems against pollution and other stressors. In practical terms, regional organizations can be crucial for shared monitoring, pollution response coordination, and building consistent standards across borders in a sea where water and wildlife do not respect jurisdictional lines.

On cultural heritage, UNESCO’s documentation of Iranian lenj boats provides an example of how maritime culture can be treated as heritage worth safeguarding, which can complement conservation by reinforcing community identity and continuity.

Finally, international research frameworks such as Important Marine Mammal Areas show how biodiversity evidence can be synthesized into actionable place based priorities. The Nakhiloo Coastal Waters factsheet is an example of a source that is both scientifically grounded and designed to support management decisions, including in areas that face coastal development and fisheries interactions.

What to expect and what to watch

Iran’s coastal biodiversity sits at the intersection of three forces.

The first is climate stress. The Persian Gulf is already an extreme environment, and coral bleaching research across the region underscores how warming and heat events can push systems beyond recovery thresholds. Climate change also interacts with water management and land use decisions inland, as shown starkly in the Lake Urmia case, where reduced water availability and salinity shifts have reshaped bird communities over time.

The second is development pressure. Ports, coastal construction, and industrial zones can fragment habitats and degrade water quality, especially in shallow systems and estuaries. The habitats that matter most, mangroves, seagrass, mudflats, and nearshore reefs, are also the habitats most likely to be impacted by dredging and shoreline engineering.

The third is volatility. In March 2026, the war has created an acute layer of risk for the Strait of Hormuz and surrounding waters, with real implications for shipping safetyspill probability, and coastal community stability. Biodiversity conservation is always difficult in politically complex environments. It becomes even harder when attention and resources are pulled toward immediate security and humanitarian needs.

And yet, there is a constructive way to think about this moment. Iran’s coasts are not defined only by threat. They are defined by a rare combination of ecological productivity and cultural depth: mangrove labyrinths that function as nurseries, islands that host nesting turtlesdolphins that still maintain resident populations in shallow coastal waters, and a maritime heritage that has adapted for centuries to seasonal rhythms and environmental extremes.

For readers outside Iran, the most useful stance is not pity or distance. It is curiosity paired with humility. Iran’s biodiversity is real, it is complex, and it is not reducible to headlines. If anything, the current crisis is a reminder that environmental literacy is not separate from human events. It is part of how we understand what is at risk, what endures, and what recovery could mean, for ecosystems and for the people who live with them.

Falmouth Harbour Trials the World’s First All-Concrete Pontoon Float to Replace EPS in Marinas

Falmouth Harbour is trialling the world’s first all-concrete marina pontoon, designed by Cornwall-based ScaffFloat, as a recyclable alternative to Expanded Polystyrene floats and a step toward cutting marine microplastic pollution.

Falmouth, Cornwall, UK. Falmouth Harbour is trialling the world’s first all-concrete marina pontoon float, designed and built by the team at ScaffFloat in neighbouring Penryn, in a first step to removing all Expanded Polystyrene (EPS) floats from its leisure and commercial operations.

The Harbour has pledged to move away from EPS products in the light of mounting evidence that polystyrene microplastics in the world’s oceans inflict serious damage on the marine environment and life within it. Polystyrene, globally used for its lightness and buoyancy, is made from fossil fuels, is virtually un-decomposable, and when it breaks down into microplastics can be ingested by marine life with devastating consequences.

“The amount of broken-up polystyrene around our creeks and rivers, particularly after this year’s storms, is awful to see and very hard to clean up without damaging the delicate ecology of our shorelines. Expanded Polystyrene fragments in the marine environment pose a serious ecological concern, as seabirds, fish, turtles and other fauna mistake EPS beads for food, which can cause internal injuries or death; entering the food chain poses health risks to humans as well.”

Vicki Spooner, Environment Manager, Falmouth Harbour

Inside the Reef Float: an inert, recyclable alternative to EPS

Penryn marine company ScaffFloat Ltd has tackled the challenge of finding alternatives to traditional pontoons by inventing the “Reef Float.” Their first commercial prototype, made entirely from concrete, has been undergoing trials beneath a Falmouth Harbour pontoon. ScaffFloat developed the new product as part of a business development project that received £284,787 from the UK Government through the UK Shared Prosperity Fund as part of Cornwall’s Good Growth Programme.

The Reef Float’s buoyant core is made using ultra-low-density waterproof concrete, instead of EPS foam, and the core is then cast inside a high-strength engineered concrete skin. In the highly unlikely event that a Reef Float ever failed, the materials would simply sit inertly as stone in the marine environment, whereas a cracked-open EPS float exposes its polystyrene foam core to the marine elements.

“We replaced a failing EPS pontoon float at Falmouth Harbour with a Reef Float, where it survived all that this January’s storms could throw at it. It’s what we would expect, of course, as we’ve designed it to be strong with an ultra-long life. But it’s also completely inert in the marine environment and 100 percent recyclable, so a game-changing alternative to the EPS floats currently used all over the world.”

Toby Budd, Founder and Managing Director, ScaffFloat

Local innovation, global stage

Local MP Jayne Kirkham, checking out the new Reef Float in Falmouth, called it “exactly the kind of innovation we want to see in Cornwall: local businesses developing practical but cutting-edge solutions to global environmental challenges. Cutting polystyrene pollution from our waters while creating skilled jobs is a win for our marine environment and our economy. I’m proud to see government funding helping projects like this lead the way.”

“Falmouth Harbour has made the conscious decision to move away from EPS foam pontoons in all our operations, and it’s fantastic that our neighbours at ScaffFloat are the first company to offer a plastic-free alternative. Reef Floats are easily installed, in situ, on a rolling basis, as and when we need to replace old EPS floats, and they have a zero-cost, 100 percent recyclable end-of-life disposal. It’s another tremendous example of Cornish ingenuity, and we look forward to working with them into the future.”

Miles Carden, CEO, Falmouth Harbour

The Reef Float team has been shortlisted for the Innovation Award at Marina26 in Australia this May, with an invitation to attend and present at the biggest marina conference in the world, demonstrating what a major issue EPS has become for the marina industry and legislative authorities alike.

Australia itself lost more than 1,000 pontoons in the 2022 Queensland floods, where they broke up and created an environmental disaster known as the “White Spill,” with the ocean and beaches covered with EPS balls that were almost impossible to clear up.

New Satellite-Based AI Approach Reveals Ocean Currents in Unprecedented Detail

A study published in Nature Geoscience introduces GOFLOW, an AI-powered method that turns existing weather satellites into a high-resolution lens on ocean surface currents, with implications for climate models, search and rescue, and oil spill response.

KINGSTON, R.I., April 20, 2026. A new study published in Nature Geoscience describes an artificial intelligence-powered technique that can measure ocean surface currents over broad areas in greater detail than ever before. Among the co-authors is Nick Pizzo of the University of Rhode Island Graduate School of Oceanography.

Called GOFLOW, short for Geostationary Ocean Flow, the approach uses AI to analyze thermal images from weather satellites already in orbit. Because it relies on existing satellites, no new hardware is required, marking what researchers describe as a major advancement in ocean observation.

The study was co-led by Luc Lenain of the Scripps Institution of Oceanography at the University of California San Diego and Kaushik Srinivasan of the University of California, Los Angeles. Co-author Roy Barkan of Tel Aviv University and Pizzo are also alumni of Scripps. The project was supported by grants from the Office of Naval Research, NASA, and the European Research Council.

Ocean currents and vertical mixing

Ocean currents play a huge role in shaping Earth’s weather and climate, transporting heat around the planet, moving carbon between the atmosphere and ocean interior, and carrying nutrients that support marine life.

“In areas where the ocean pushes together and pulls apart, information from the atmosphere and ocean interior are exchanged in ways we do not fully understand. This is one of the most exciting areas of physical oceanography today.”

Nick Pizzo, URI Graduate School of Oceanography

Understanding currents also matters for search-and-rescue efforts and for tracking the movement of oil spills. Yet measuring currents across large stretches of ocean has remained extremely difficult. Some satellites only revisit the same location about every 10 days, too infrequently to capture currents that can appear and disappear within hours. Ships and coastal radar can track faster changes, but only in limited areas.

This has left a persistent gap in observations at the scales where most of the ocean’s vertical mixing occurs, when shallower waters are mixed deeper, or vice versa. The phenomena that drive vertical mixing can be less than 10 kilometers (six miles) wide and transform in hours. Vertical mixing matters because it powers key processes such as bringing nutrients up to the surface and pumping carbon dioxide into the deep ocean, where it is stored long-term.

Deep learning, applied to a moving ocean

The GOFLOW team trained an AI model to recognize how surface temperature patterns shift as water moves below. The neural network learned from advanced computer simulations of ocean circulation, then applied that knowledge to real satellite imagery from the North Atlantic collected by the GOES-East weather satellite. The researchers tested the method against shipboard observations in the Gulf Stream and found that GOFLOW matched existing measurement techniques while revealing much finer detail, capturing smaller, more energetic features linked to vertical mixing.

For scientists such as Pizzo, these advances open new opportunities to study ocean dynamics through actual observations rather than relying primarily on computer models.

“We are using this real-world inference to better understand how the ocean transports important quantities like heat from one place to another, and how vertical motions that are important for exchanges between the atmosphere and the ocean are supported.”

Nick Pizzo, URI Graduate School of Oceanography

Because GOFLOW works with satellites already in service, the method could eventually be integrated into weather forecasts and climate models, helping improve predictions of ocean-atmosphere interactions, marine debris transport, and ecosystem change. The researchers are now working to expand the method globally and to improve performance when cloud cover blocks satellite views.

Sounds of the Ocean: A Journey from Inspiration to Impact

Every meaningful project begins with a moment of connection—an experience that shifts perception and plants the seed for something larger than oneself. Sounds of the Ocean was born from such a moment: while teaching a yoga class, it struck me how deeply sound can influence presence and awareness. As students moved through their breath and stretches, I realized that auditory experience could guide attention, calm the mind, and connect people to something larger than themselves. This insight sparked the idea: what if the hidden soundscapes of the ocean could be used in the same way—to foster presence, reflection, and a profound connection to our planet?

The ocean has always been both a place of mystery and calm—a space of reflection and immense unseen activity. While many experience it visually, few are aware that it is alive with sound. From the complex songs of whales and dolphins to the low-frequency hum of shipping lanes, the ocean is anything but silent. The idea behind Sounds of the Ocean was simple yet powerful: what if people could truly hear the ocean, not as background noise, but as a living, breathing entity?

This curiosity led to an exploration of underwater acoustics—the science behind how sound travels in marine environments—working closely with my colleague Dr. John Ryan, Senior Marine Acoustics Oceanographer at MBARI. Together, we investigated how whale songs reveal migration patterns, dolphin clicks uncover social interactions, and the pervasive noise of shipping offers insight into the human impact on marine life. These collaborations allowed us to understand the ocean not just as a visual landscape, but as a complex, communicative environment shaped by both nature and human activity.

The recordings used in Sounds of the Ocean are captured using specialized hydrophones, underwater microphones designed to detect even the faintest vibrations. These recordings are both scientific documents and artistic expressions. While the data helps researchers monitor ecosystems, the same sounds can be transformed into immersive compositions that evoke emotion and curiosity. Some performances incorporate whale calls recorded near shipping lanes, highlighting both the majesty of marine mammals and the impact of human activity on their acoustic environment.

This combination of science and art naturally led to opportunities to present the project on global stages, including United Nations Climate Conferences and COP events. Sharing Sounds of the Ocean in these contexts has been both an honor and a responsibility. These gatherings bring together policymakers, scientists, activists, and storytellers, all working toward solutions for the climate crisis. In such spaces, data and policy dominate—but there is also growing recognition of the role of emotion and narrative in driving change.

Presenting at these events has highlighted the unique role that sound can play in climate communication. While charts and reports inform, sound can transform understanding into empathy. Audiences often experience a moment of stillness when they first hear the underwater recordings, as if the ocean is speaking directly to them—bypassing intellectual analysis and connecting on a more instinctive level. That moment of connection is where awareness begins to shift into action.

Collaboration has been central to amplifying this impact. Sounds of the Ocean has partnered with a diverse range of leading scientific and environmental organizations:

  • MBARI (Monterey Bay Aquarium Research Institute) provides access to cutting-edge marine research and high-quality underwater acoustic data.
  • Oceanic Global connects the project to international networks of ocean conservation, translating awareness into tangible action.
  • UN Ocean Decade offers a global framework for ocean research and sustainable development.
  • 1% for the Planet supports environmental funding and advocacy.
  • EU4Ocean platform links European stakeholders in science, policy, and society.
  • everwave removes plastic from rivers, reducing debris entering the ocean—a mission highlighted in performances that connect river health to marine soundscapes.
  • PMDP (Papahānaumokuākea Marine Debris Project) monitors and removes marine debris in one of the world’s most remote and ecologically important marine areas, allowing us to incorporate recordings from cleaner, protected waters and emphasize the importance of debris-free habitats for whales and dolphins.

These collaborations reinforce a key insight: meaningful change requires collective effort. No single discipline or organization can address the complexity of the climate crisis alone. By bringing together scientists, artists, institutions, and communities, Sounds of the Ocean becomes part of a larger ecosystem of solutions—one that values both knowledge and emotion as drivers of change.

As the project evolves, its direction is guided by a central question: how can we deepen the connection between people and the natural world? Live performances in immersive venues, such as planetariums and cultural spaces, allow audiences to be enveloped by sound, creating a sense of presence within the ocean itself. These events transform listening into a shared, collective experience that fosters dialogue and reflection.

Another exciting development is bringing these experiences directly into the field. In collaboration with the Pacific Whale Foundation in Maui, we are designing whale-watching tours where participants wear high-quality wireless headphones to hear whales live, directly under the boat. This approach allows passengers to experience the animals’ vocalizations in real time, bridging the gap between scientific observation and immersive human connection. Hearing whales in their natural environment while also observing them visually fosters a deeper appreciation for these magnificent creatures and the importance of protecting their habitats.

Integration of new technologies also continues to expand the project’s reach. Spatial audio, interactive installations, and virtual environments offer ways to bring ocean soundscapes to life. Imagine walking through an exhibit where each step reveals the calls of whales or the hum of shipping lanes, or experiencing a live performance where sound moves dynamically around the listener, mimicking the fluid nature of the ocean. These innovations make the experience engaging and impactful, particularly for younger audiences.

Education remains a vital focus. By collaborating with schools, universities, and educational platforms, Sounds of the Ocean serves as both an artistic and scientific resource. Introducing students to the acoustic dimension of the ocean enriches understanding of marine ecosystems and encourages curiosity and stewardship. When people feel connected to something, they are more likely to protect it.

Ultimately, the journey of Sounds of the Ocean is one of translation—turning scientific data into emotional experience, distant ecosystems into immediate presence, and awareness into action. It is a reminder that the ocean is not a distant, abstract concept, but a vital, living system that shapes our planet and our future.

Looking ahead, the vision is to continue building bridges between disciplines and audiences.
