New England Aquarium Scientists Spot Critically Endangered Right Whales in Unusual NY Feeding Ground
Scientists from the New England Aquarium’s Anderson Cabot Center for Ocean Life have spotted over 82 unique North Atlantic right whales – including 56 in one day. These whales, representing over one quarter of the entire North Atlantic right whale population, were sighted during a series of flights between the end of July and into August about 40 to 70 miles south of Long Island, New York, an area highly trafficked by vessels and an unusual feeding ground for the critically endangered species.

“This mid-Atlantic aggregation is a good reminder that the movement patterns of North Atlantic right whales are always responding and adapting to changing ocean conditions,” said Katherine McKenna, an Anderson Cabot Center research scientist who was aboard several of the five aerial survey flights. “This multi-month grouping of whales south of Long Island is very unusual.” In recent years, there has been widespread redistribution of right whales as they respond to changes in where their prey is located.
North Atlantic right whales were seen in the Hudson and Block Canyon areas south of Long Island along with an abundance of fin and humpback whales, various dolphin species, manta rays, whale sharks, tuna, and sea turtles. Hudson Canyon is a vast submarine canyon over 70 miles off New York and New Jersey at the outlet of the Hudson River. Block Canyon is a smaller canyon approximately 50 miles northeast of Hudson Canyon.
Typically, whales congregate in areas where they can feed efficiently. North Atlantic right whales have likely been feeding in that area for months now, and their presence near the canyons could indicate plentiful food. The scientists observed the whales spending up to 10 minutes under the surface before re-emerging in the same areas and occasionally defecating – both behaviors indicate feeding.
An aerial survey team with Northeast Fisheries Science Center (NEFSC) first documented this aggregation at the end of May and continued to document it in the period before the Anderson Cabot Center team’s sightings. “The sightings and aerial surveys by the Aquarium team have been critical to helping understand the right whales’ use of the region,” said Tim Cole, a research fisheries biologist with NEFSC.
Currently, no mandatory speed restrictions, which are known to reduce the risk of lethal vessel strikes to large whales, exist where these aggregations have been sighted. The proximity of such a large proportion of the population to a busy marine traffic area for so long raises concern about the risk of vessel strikes to these whales. Several were seen with propeller wounds, which serves as a reminder that it is important for mariners to be on the lookout for whales, even when mariners are not traveling in mandatory slow zones.

NOAA is currently considering modifications to the existing vessel speed rule to better protect North Atlantic right whales. Proposed changes to the federal vessel speed rule include expanding the size of areas with seasonal speed restrictions, increasing the length of time speed restrictions are in effect, extending restrictions to include most vessels measuring 35 to 65 feet in length, and implementing mandatory speed restrictions in dynamic speed zones, which are established when and where whales are observed and likely to persist. Aquarium scientific research shows that the proposed expansion of the speed restriction areas will increase protections for North Atlantic right whales and that other large whale species would also benefit. The proposed rule was published in August 2022 but has not yet been finalized. The untenable delay has put this endangered species at continued risk of extinction.
Vessel strikes and entanglement are the two leading causes of serious injury and mortality for North Atlantic right whales, a critically endangered species with less than 360 individuals remaining. The Aquarium also documented fishing gear near the whales seen in the Hudson and Block Canyon areas south of Long Island. The New England Aquarium urges immediate, science-based action to reduce those threats.

Where Blue Becomes Green: Lessons From Thailand’s Turbid Reefs
By Sophie Coxon
The island is washed into the water, clouding the blue sea green, shielding the reefs from the searing sunlight and settling in a blanket of soft murk over the undulating coral landscape.

A tidal wave of coral research and restoration has swept the global oceans and lapped at shallow coastlines over the past few decades, spurred by the increased appreciation for coral reef ecosystems and the value these habitats contribute to planet Earth. The kaleidoscopic kingdoms of sunlit reefs, sparkling in crystal clear waters and pulsing with shoals of fish, turtles and the shadows of sharks, attract a huge influx of attention due to their aesthetic appeal and hence receive the majority of research funding. But other kinds of reef exist, and may hold invaluable resilience to pressures and stresses which could unlock new hope for the future of conserving the planet’s struggling coral reefs. If we can look deeper than surface-level appearance and place value in grittier realms, the tools required to combat coral reef decline may be within reach.
The island of Koh Phangan is well stamped on the maps of young backpackers and travellers, known for its infamous full moon parties and zen yoga community. The island acts as a stepping stone for divers on their way to the marine paradise of Koh Tao, one of the world’s most heavily dived regions, famed for its vast coral reefs, anemone beds and vortexing tornadoes of trevally and barracuda. However, the reefs of Koh Phangan, only a few kilometres south, lie relatively unscathed by the bubbling swarms of divers. This is no doubt due to the fact that these reefs are turbid, exhibiting vastly different ecological conditions to the crystalline water column and flamboyantly technicolour reefs of Koh Tao. In the summer of 2024 I spent three magical months on this island, and my understanding and appreciation of these cloudy, silted, plankton-infused reefs took spark.
Turbid reef systems are significantly understudied in comparison to their oligotrophic counterparts, though are beginning to gain interest as the struggle to develop long-term coral restoration techniques intensifies. Characterised by high levels of suspended sediment, increased algal cover and low coral diversity, turbid reefs inhabit vast areas of shallow tropical and temperate coastlines, including 30% of the Coral Triangle, the most biodiverse reef region on the planet. High sedimentation levels are often classified as a stress to coral reefs, however naturally turbid systems are well adapted to these murky conditions, and may even benefit from the abundance of silt, plankton and organic matter that enshrouds them.
Whilst corals growing within turbid ecosystems exhibit slower growth, they also show improved stress tolerance, reduced bleaching and lower mortality rates than those in non-turbid systems, and are robust against the plethora of pressures burdening shallow ecosystems provoked by climate change and growing anthropogenic exploitation. Recent research has suggested that the suspended particles reflect a large percentage of UV radiation which exacerbates bleaching, and the inhabitant coral colonies are accustomed to being smothered by sediment, constantly producing mucus which sloughs off any surface debris. Plainly put, turbid reef systems are not the picturesque kingdoms of tropical colour and aquatic enchantment that springs to mind with the words ‘coral reef’, however the biodiversity they harbour and ecological services they supply are no less important.

I was integrated into a team of researchers at the COREsea station on the north shore of the island, spending long days diving in the various bays collecting data for long-term monitoring projects, as well as conducting my own research study on fish assemblages across reef zones. We assessed reef substrate composition, bleaching cover, coral predators, fish communities and giant clam abundance across the survey sites, compiling everything in a decade-long data archive – a live picture of the trends, dynamics and fluctuations occurring on Koh Phangan’s murky reefs. No other similar research has been published on this specific region, leaving a gaping hole in the scientific literature and our understanding of Thailand’s tropical turbid reef systems.
Though naturally turbid and rich in organic matter, with the onslaught of development and increasing tourism, Koh Phangan’s reefs are becoming inundated with threats. Construction and forest clearing on the island’s junglish slopes loosens sediments, which are rapidly washed into the surrounding coastal waters with every monsoon downpour. The footprint of the tourist industry is also leaving its mark, with pollution and disturbance accelerating every year, combining with the effects of climate change to push the already overfished and exploited reefs to the edge.
Researching these ecosystems is crucial to protecting and preserving them; without establishing biodiversity baselines and monitoring the temporal changes occurring, it is impossible to predict future outcomes and support new protection measures that may be fundamental to preventing degradation.
Throughout my time working on these reefs, I became closely familiar with the patterns and quirks that instilled a certain charm to the ecosystem. There was as much beauty here as any other reef I had dived, it just took a more willing eye to see it. After only a few days, I felt at home in the greenish murk, the glowing white streak of the transect line the only sense of direction in the vast expanse of coral canyons, pillars and plateaus that stretched out around me. Nudibranchs could be found speckled across the boulder corals, where pairs of butterflyfish sucked corallites through puckered lips and cushion stars lay, plump and velvety, like pincushions placed on coral plates. The jade-tinged haze of the water cloaked everything in mystery, blurring the silhouettes of fish into translucent shadows and suggestions, obscuring the treasures of the reef from all but the most vigilant observers. However, the blinding white scars of bleached coral gradually became more and more abundant across the reefs, like warning beacons signifying the beginnings of a disaster.

Not long into my stay, an ocean heatwave singed the globe, and the Gulf of Thailand simmered. As sea temperatures soared into the mid 30s (Celcius), a plankton bloom engulfed the bays and the visibility dropped to between 1 and 2 metres. The water column was thick and green, and the monsoon rains sent rivers of sediment pouring onto the reefs every afternoon. The dives went on, and we continued monitoring the reefs, watching them turn a ghostly white before us. By the end of my three month research period, huge areas of the reefs were completely bleached, and finding a coral that was unscathed by bleaching was near impossible.
Whilst bleaching is not immediately fatal, if conditions remain inhospitable for a lengthened period, many coral colonies, some close to a century old, may succumb to this slow and pallid death, leaving nothing but empty skeletons to dissolve in the acidic seawater that once gave them life.

The snapshot of coral bleaching I was exposed to throughout my research period was both eye-opening and eye-watering. The severity of the issue was branded into my mind with every subsequent dive, the tally marks in the ‘fully bleached’ column multiplying each time, filling the clipboard with grim black smudges. The toughest, most resilient reefs we know of are now failing under the crushing weight of climate change and human interference. But the future of these reefs can still be steered towards vibrancy – to lose them would mean a loss of food and livelihood for the hundreds of local communities who call the Gulf of Thailand home, and would have deep-rooted impacts across marine food webs, affecting biodiversity throughout a vast region of ocean. The cushioning effect provided by the toughened forms of ancient bouldering corals would leave coastlines open to the elements, and the fronds of life on the reef, woven tightly into the tapestry of the local cultures and traditions, would be lost.
There is more to turbid reefs that initially meets the eye, and we must enrich our understanding, connection and appreciation of these systems to grant them a place in our restoration frameworks. With more research, like the work carried out by the dedicated team at COREsea, the mysteries of these reefs and the limits of their resilience can be uncovered and shared across global reef conservation.

Navigating Growth in Conservation Careers and Finding Balance in an Unbalanced World
For many of us working in conservation, the path we’ve chosen is more than just a career, it’s a way of life. But as we move forward in our roles, the weight of what we see and experience can take a significant toll. Habitats destroyed. Species extinct. And sometimes, even when we do everything right, the larger systems at play don’t allow for the success we hoped for. The science was right when we were children, and today we’re witnessing the price being paid- by the planet, by humanity, and by the fragile ecosystems we’ve devoted our lives to protecting.
In the face of these overwhelming realities, it’s not uncommon for conservationists to experience burnout. We ask ourselves: Is it alright to take a break from conservation? What happens when hope is lost?
The Need for Breaks and Rediscovery
Yes, it is alright to step away, to take a pause. In fact, it’s necessary. Conservationists, like anyone else, need time to process, recharge, and reflect. Without these breaks, our mental, emotional, and physical health can deteriorate, which ultimately limits the impact we’re able to make.
When hope seems lost, that’s precisely when it’s time to reevaluate and ask some fundamental questions about why we’re here. Are we dedicated to the mission of an organization? To the preservation of a specific species or habitat? Or are we here because of a deep-rooted desire to make the world a better place, whether for a single animal, plant, or entire ecosystems?
Continuing Education: Traditional and Non-Traditional Paths
One way to rekindle that initial passion is through continuing education. This doesn’t always have to be in the traditional sense, such as earning an additional degree or certification, though those routes certainly offer value. But for those who have spent too much time behind a computer, it might be worth considering more non-traditional forms of education: immersive field experiences, hands-on workshops, or even short-term volunteering in places that inspire you. These opportunities not only provide a chance to learn but also serve as a powerful reminder of why we began this journey in the first place.
If you’re feeling stuck, getting out into the field, even for a short time, can shift your mindset and offer new perspectives. Seeing conservation work in action, whether it’s in a remote forest or a coastal village, has a way of reigniting the passion that brought you here in the first place.
Redefining Success in Conservation
Conservation is not a linear career path. The traditional markers of success, climbing the ladder, earning a promotion, don’t necessarily apply here. It’s always healthy to redefine what success looks like, both in terms of your personal life and professional career. You may find that after years of dedication, your goals and aspirations have shifted. And that’s okay.
We didn’t get into this field for money, but our health and security need to come first. Whether that means shifting to a role that prioritizes balance, or reimagining the impact you want to have, there’s no wrong answer.
Finding Contentment Amid Loss
The heartbreaking reality is that we won’t save everything. But that doesn’t diminish the value of what we do. It’s important to find peace with where we are- not necessarily where we’re headed. This means accepting that while we may lose biodiversity, habitats, and even hope at times, we must continue striving for that balance between what’s possible and what’s realistic.
At the end of the day, most of us in this field are here because we care deeply. We care about the world, its people, and the creatures that inhabit it. Our daily efforts, even if small, make the world better than it was yesterday. And that’s enough.
So, whether you’re at a crossroads in your career or just need a reminder of why you’re here, remember that it’s okay to pause, rethink, and redefine what matters most to you. After all, the only constant in conservation is change- both in the world around us and within ourselves.
