Shark Tagging in the Revillagigedo Archipelago
Courtney Mattison
“You shouldn’t notice such a big difference in shark abundance over a ten year period,” remarked Shane Taylor of Fins Attached after returning from a dive at Roca Partida, one of the four volcanic islands of the Revillagigedo Archipelago. “Ten years ago, you would have had to swim with your eyes closed to not see groups of Galápagos and silvertip sharks and even a wall of hammerheads on every dive” he said, recalling his first visits to the islands. “It’s hard to take the temperature of a place from one or two days of diving since things change every day,” said Mission Blue Board Director Shari Sant Plummer. “But compared to stories we’ve heard from even a few years ago, there seems to be a big difference.”

Data about where sharks feed, have their pups and migrate help researchers identify places of special importance to shark conservation. “It’s very important to collect these data because we want to know how much these animals are using the marine reserves,” says Dr. James Ketchum of Pelagios Kakunja —the lead scientist sponsored by Fins Attached on our recent expedition. “This gives the park managers more data to support their existence.” Data collected by Dr. Ketchum and his team support the creation of networks of marine reserves, or better yet, no-take marine protected areas (MPAs) where all extractive uses, like fishing, are prohibited. “The key to protect these species is to make networks of marine protected areas,” says Dr. Ketchum.

New findings from acoustic tags placed on sharks in the Revillagigedo Archipelago reveal corridors of movement between the islands and the Gulf of California and broader Mexican Pacific, making these networks of protected areas more important now than ever thought before. Sharks outfitted with acoustic tags send signals to monitoring receivers planted underwater at around 30 meters (100 feet) deep throughout the region. When a shark comes within the 300-meter range of an acoustic receiver its tag sends a timestamp, allowing researchers to trace movements of individual sharks and recognize patterns in their behavior.
Protected species of sharks are sold on the black market to satisfy Chinese demand for shark fin soup, while unprotected ones are legally sold for their meat, with their fins also exported to Asia. Only whale sharks, great whites and basking sharks are protected under Mexican law, putting the sale of other more common (yet extremely threatened) species up for grabs. For example, the Eastern Pacific population of scalloped hammerhead (Sphyrna lewini) is listed as endangered by the IUCN Red List of Threatened Species (http://www.iucnredlist.org/) and the U.S. Endangered Species Act (http://naturalresources.house.gov/esa/), and is also listed on CITES (Convention on International Trade in Endangered Species) Appendix II (http://www.cites.org/eng/app/index.php), which prohibits international trade of shark products from this species without first verifying that these animals are being fished sustainably with legitimate certificates of origin. Yet in Mexican waters, the scalloped hammerhead is fair game.

Recording patterns in shark migration, feeding and reproduction behavior is more important now than ever before, as advances in tracking technology make it increasingly easy to understand how and where to protect key habitat. More robust research findings are also making it more compelling for policymakers to base regulations on science. Today in the Revillagigedo Archipelago, Dr. Ketchum says:
Fishermen can go in between the islands and fish whatever they want. But our proposal based on these studies is to make no-take zones of 40 nautical miles radius around each island, and in this way create a large no-take zone around the San Benedicto, Socorro, Roca Partida triangle of islands. We are also proposing a very large (400,000 square km) marine protected area around the whole archipelago, where fishing is limited.

By documenting the tagging process, Mission Blue aims to raise awareness about how tagging is valuable for protecting species under constant threat. “One of our long-range goals is to highlight the work of Dr. James Ketchum and Fins Attached so that the public understands the importance of studying sharks and protecting shark migration corridors and marine reserves,” says Kip Evans, Director of Expeditions and Photography for Mission Blue. He continues, “When these sharks leave the boundaries of the MPA, they get hammered. Essentially, there are no protections for them. So tracking data is essential to help us recognize the importance of these shark migratory corridors and help policymakers understand how to protect them.”
As Mission Blue embarks on its shark conservation program for 2017, we seek to support our partners and push the Revillagigedo Archipelago into full protection, including designation as a sanctuary for sharks with surveillance to enforce protection of these species. Join us by supporting our partners at Fins Attached (http://www.finsattached.org/) and Pelagios Kakunja (http://pelagioskakunja.org).

Feature Destination
Raja Ampat, the most colorful reefs of the world
The Pindito
West Papua, known locally as Irian Jaya, is a unique dive region. Probably the best known archipelago is “Raja Ampat” which roughly means “united kingdom”. The area has over 1,500 islands. The four main islands are Misool, Salawati, Batanta and Waigeo.

The word “fantastic” summarizes the region “Raja Ampat” well. Photo-and videographers find the best opportunities to create macro shots at its finest. But also wide-angle shots of the beautiful reef life are recommended. There are countless dive sites, all with different characters. The attentive viewer can find all sorts of “macro-animals” in crevices and on terraces of steep walls. “Raja Ampat” is also a Mecca for lovers of pygmy seahorses. These cute dwarf seahorses are found here in every shape and color, red, yellow, orange, purple or white.

Misool
Diving in the endless maze of the islands of Misool is a very special treat for any diving career. It is paradise for macro enthusiasts, but encounters with larger fish such as manta rays are often possible. Misool is one of the most biodiverse regions in the world with fish, corals, sponges, soft corals, shrimps, crabs and countless nudibranchs and other invertebrates. Huge shoals of sardines are a definite highlight. Soft corals and sea fans (diameter of 3-4 meters) in all sizes and colors dominate the underwater landscape.

One of Pindito’s special places is called “Vrenelies Gärtli” (in English it means Vreni’s Garden). It is a legendary dive site that has it all, because of it’s very diverse landscape. Overhangs, huge caverns with swimthroughs, lush steep walls with all kinds of corals are found here.

Waigeo
A special feature of this tour is the crossing of the equator. This area has a fascinating landscape. Many of the famous Raja Ampat landscape photographs were shot here. On the north is the island Wayag with the famous “Mount Pindito”, from where you get a fantastic view of the many islands. Pindito on anchor in the middle of the Bay, completes the beautiful landscape. “Sele Pele” offers the opportunity to look at a pearl farm up close. Depending on the production stage you will be invited to witness the fertilization or harvest! A unique opportunity you cannot afford to miss.

“Jef Fam” is the name of a group of karst islands with great diving, lots of fish and colorful corals. Night dives at the “Red Wall” are always a special experience. In the sand under the pearl diving pier a lot of special and peculiar creatures, especially wobbegongs and epaulette sharks (walking sharks) can be found. Countless nudibranchs, pipefish, seahorses, frogfish, scorpion fish cannot escape the well trained eye. A great highlight is the manta cleaning station near Mansuar.

Dampier Straight
The Dampier straight separates the “Vogelkop” (Birdshead) Peninsula from Waigeo and Mansuar. The name comes from the Dutch colonial times. It refers to the shape of the peninsula on the map, but it is also a paradise for many rare bird species.

Pindito puts great importance to plan the best possible tour for their guest. When planning the route, many factors play an important role. The most important factor is the weather. Since there can be storms in the tropics at any time, Pindito might change routes and itineraries at short notice.
The second tour leads north from Sorong visiting Wayag Island, which lies west of Waigeo. The dive areas are the Dampier Straight, Jef Fam, Sele Pele and Wayag. The tour ends in Sorong.

OCEANIC SOCIETY ARTIST-IN-NATURE RESIDENCY! BALI TO KOMODO
Pam Longobardi
2014 marked the start of a new adventure: I became the official Artist-In-Naure with Oceanic Society! Founded in 1969, Oceanic Society is the oldest ocean conservation non-profit in America, focused on using the experience of travel in nature as a tool to deepen the connections between people and the natural world. Their progressive leadership has introduced two initiatives in 2014: to address plastic pollution and to promote art as a conservation tool. My first trip as Artist-In-Residence was co-leading the 10-day Bali to Komodo expedition on the live-aboard schooner Sea Safari VII with naturalist and Oceanic’s Director of International Travel and Sustainability Wayne Sentman. My role as ‘Plastic Interpreter’ meant that, given the plastic plague in Indonesia, like most island nations, my work was cut out for me.

Our 10 day voyage took us to remote large and tiny islands sprinkled between Bali and Komodo:
Lombok, Moyo, Gili, Banta, Satonda. We usually spent 5-6 hours in the water each day, snorkeling through the underwater marvels that are Indonesia. The fellow voyagers were spying and photographing fish and sea creatures for Wayne to identify with his encyclopedic knowledge of Indonesian flora and fauna, and I took 1000s of photos of the teeming life of the coralline ecosystem.

Coral Garden
Coral gardens of indescribable beauty in multitudinous forms and textures, myriad fish in ten thousand hues, cuttlefish, sea snakes, nudibranchs, crawling oddities like the feather sea star (looking like a blood-red feather duster on spider legs), echinoderms, “sea stomachs” (actually tunicates) and more! A manta ray. A few small sharks, whose general absence was troubling: where there should have been many sharks, they were scarce, victims of nefarious shark finning. And areas where luxurious coral gardens had been blasted into rubble field thanks to the insanity of dynamite fishing.
But even amid the destruction, there are signs of hope: new coral heads budding out of the rubble with the attendant sea life they attract. I am thankful for the ingenuity and creativity of nature, whose regenerative force builds anew in a field of destruction~

I spent my time diving down to remove sunken plastic (not all plastic floats) and cut fishing line and nets free from coral. Some plastic had been underwater so long it had been colonized and encrusted with life, pieces that had so many lives attached I left them in situ. Soon, many of the fellow voyagers were collecting underwater plastic along with me.

80% of ocean plastic originates on land, and has its impacts on wildlife there as well: this mother and baby macaque on Lombok are both chewing on plastic, the mother scavenging food that looked like carrots packaged in plastic while the baby makes a plaything and teething device out of a plastic bottle.

Komodo dragon ‘smelling’ with their eerie white forked tongues
A highlight of the trip was Komodo Island, the only place in the world home to the living dinosaurs, the Komodo dragon. Truly fearsome, venomous, these very large and powerful predators will cannabalize their own young, and lay in wait, camoflauged in the dust, for the unaware deer -or human -to stumble on them. Fangs rip flesh and inject venom, but the smart reptiles save their energy and wait for death by infection to overcome their victims. We saw dozens upon dozens of the creatures , a rare day indeed that included witnessing a mating attempt, a gathering of adults and young at a water hole, and a scrabble over the remnant ribcage of the morning’s deer kill. Guides and visitors watchfully hike through the dragons’ land: there are no cages, barriers or protection, and attacks do occur – last year 3 guides had been bitten as dragons entered their offices and attacked. In the presence of these creatures, in all their ancient-ness, their otherness, I experienced spine-tingling awe.

Komodo dragon bolus with plastic RIO water
And then I noticed a bright blue piece of plastic enmeshed in a compressed, elongated ball of matter. I realized it was a 5 gallon plastic bottle cap of the kind that all the cruise ships carry as their fresh water stores. It had been eaten, swallowed and regurgitated by a dragon in a ‘bolus’, just as albatross, owls and other birds do to get rid of undigestible matter they have eaten.
Shockingly, even the komodo dragons are eating and swallowing plastic, creatures whose evolutionary path leads as far back as the fossil fuel that the plastic is made from.
I made many beach landings, usually by swimming from the Sea Safari, to survey and clean the remote island beaches. Some of them were completely inundated like Gili Lawa Laut Island. I gathered as much as I could swim with and bundled it all together or utilized the large plastic mesh produce bags that appeared everywhere, even underwater, where they readily break up into micro-plastic.
My most heartwarming moment came when I was joined by a half dozen beautiful children as I cleaned their island of Moyo . They saw what I was doing and enthusiastically joined me. It didn’t matter that we spoke not a word of each other’s languages. But Amir, our Balinese naturalist guide, was able to give them a spontaneous environmental lesson about plastic’s dangers for the sea. Amir has been acting as a plastic warrior for years, and our being together on this expedition was providential. He is now the newest member of the Drifters Project team.

Gili Lawa Laut Island beach inundated with plastic
Indonesia is a place of untold physical beauty alongside the abundant problems of a developing country. But there is action underway: a plastic bag ban on Bali is well on its way to becoming a reality, started by a group of local and international children in Denpasar. You can help them by signing their petition here. I am sending Amir 100 stainless steel straws to begin the conversation with Sea Safari and other tour companies to replace the plastic straws onboard ships. And Oceanic Society is
looking to incorporate a ‘Plastic Free Travel Kit’ as a perk for their expedition participants. Little by little, my vision of plastic free islands can Gili Lawa Laut Island beach inundated with plastic become reality. Gili Lawa Laut Island beach inundated with plastic.
