Raja Ampat - Snorkeling Indonesia's Marine Jewel

Soft Corals Aplenty
Just returning from snorkeling the northern islands of Raja Ampat. This was the first year of Oceanic Society's snorkel expedition to this biodiversity hotspot located within Indonesia. Arriving in Sorong our group of 13 was taken to the Bidadari, a dive (or in this case snorkel) live-aboard. This vessel would serve as our ocean platform for the next 11 days. Located in the coral triangle, harboring over 500 coral species and more than 1300 varieties of fish (some just recently discovered), Raja Ampat has the distinction of being considered the most diverse coral reef ecosystem on the planet.

Each day snorkeling these remote reefs, our group was rewarded with amazing encounters. One day we were treated to a "herd" of Bumphead Parrotfish, A school of over 30 individuals paraded by us, with all members being at least 60+ pounds or more. Their size, confident manner, and shear bulk, made me think this might be the marine equivalent of savanna elephants passing one by on safari.

On other days we let the currents take us along multicolored walls covered in tunicates and soft corals. We floated along as if we had fallen down the coral reef "rabbit hole" and much like Alice, never knowing what crazy wonder lay around the next corner. These walls were rich in "macro" marine critters. Tiny animals that Raja Ampat is also know for. Here the sharp eyes of our Indonesian guides Dalton and Caroline, spotted many different types of nudibranchs. Some pictured below. The crypsis continued with scorpionfish, pipefish, and Wobbegon sharks all hidden in plain view.

Getting up each day we never knew what to expect. Each site always had a surprise in store for us and as the trip progressed we all became better at spotting our own "macros" once we took the opportunity to slow down and take a closer look at what nature was putting right in front of our noses (snorkels). Below are a few more photos to share. I will post more about the places we visited, the people that shared these reefs with us, and the coral ecosystem that we were lucky enough to float amongst in the next few days.

Ulithi Atoll - Micronesia's Snorkelers Paradise

Healthy Coral © 2011 Wayne Sentman
Ulithi Atoll is one of my favorite places to spend time in the water. The snorkeling here is incredible, with vibrant coral reefs and a diverse array of marine life, in some of the clearest water I have ever snorkeled. The clarity rivals another favorite snorkel spot, the Northwest Hawaiian Islands. This past week our intrepid group of Oceanic Society travelers left the Rock Islands of Palau flying to Yap, Micronesia. The following day we boarded a charter plane to fly 90 miles due North to the tiny island of Falalop, part of Ulithi Atoll, the second largest atoll in the Pacific. To say that Falalop is difficult to reach is an understatement. Landing on the 3000-ft. Runway we were met by a good portion of the island's 400 residents. Falalop has a small guest house and it is here that our group of 12 was based for the next four days to explore the nearby reefs and visit the community supported marine sea turtle project.

Near to Falalop are an assortment of islands with spectacular coral reef ecosystems. From colorful protected lagoon reefs to outside walls that drop off steeply into cobalt blue waters our group saw sea turtles, sharks, and many fish species. With visibility generally 80-ft or more treasures were to be found all around. Over the 7 years that I have had the privilege of visiting this island and the people that call it home I have always tried to spend as much time as possible in the water. To follow is a small sample of some of the amazing marine life our group experienced on this latest trip.

The waters of Palau never fail to delight. I am currently leading an Oceanic Society group of 11 on a snorkeling trip to Palau, Yap, and Ulithi Atoll. We have just finished our first 4 days of snorkeling and have seen some wonderful marine critters. We have covered a lot of area and the visibility has been great. We head out for Yap later tonight and are looking forward to more of the same.

Here are some recent photos so you can get an idea of the colorful reef life that the Rock Islands of Palau have on offer.

International Marine Debris Sea Turtles Created with 2010 SWOT Grant

This past month I finally saw many of the marine debris sea turtles that we asked students and community groups around the globe to create. This project was funded through a 2010 SWOT Education and Outreach grant that I wrote for Oceanic Society this past October. Our proposal was to have various groups from coastal and island communities around the globe collect marine debris from their local beaches and then construct a sea turtle art project out of it. The idea was to focus some attention to the impact plastic pollution (the main component of marine debris) has on sea turtles and their nesting habitats (tropical beach areas). We had 7 groups participate, 2 from Hawaii, and 1 each from Kenya, Suriname, Palau, Belize, and Costa Rica. Most of the groups participating were students but a few were community organizations or in the case of Palau a group of dive guides from Fish'n'Fins. The art they all created was truly inspirational. Along the way each group documented their participation with photos and in some cases video. One of the wonderful parts of this program was that many of the students organized beach collections of marine debris in order to have material to make these turtles.

           These photos show two of our student groups collecting marine debris off of local beaches. These beaches are also nesting areas for sea turtle populations. When the students went out to collect debris they made first hand field observations about the amount and types of plastic pollution they were able to find on their beaches. The volume and diversity of trash made clear to the participating groups just how large a problem plastic pollution is becoming throughout the worlds oceans. Photos like the two here illustrate how both adult and hatchling turtles are at risk from trash that washes up in their resting and nesting locations around the globe. Marine debris is not just an entanglement hazard to turtles swimming in the ocean but

  also can trap hatchlings as they emerge from nests and attempt to make their way back to the ocean. Increasingly plastic pollution that makes it way into the ocean is also finding its way into the marine food chain and is even being ingested directly by sea turtles. A recent article calls the sea turtle the new "albatross" of the seas. This as we are starting to find turtles, that like the Laysan and Blackfooted Albatross of the Northwest Hawaiian islands also have stomachs full of plastic. Given that plastic can take 20 to 1000 years to break down in the oceans it is very likely that almost all of the plastic produced by man that has EVER ended up in our seas is still there. Given the scope of the problem plastic pollution posses to human and wildlife populations the marine debris sea turtle artwork created by the various groups proved very inspirational, serving to remind us that art can offer a unique interpretation of environmental problems. An interpretation that hopefully inspires the viewer to find solutions and change behaviors (reduce use of single-use plastics) rather than be overwhelmed by the problem. To follow are pictures of the art the students created with the debris that they collected.

With all of the wonderful art that was made, we managed to display some of the items at the 5th International Marine Debris Conference that was held in Honolulu, Hawaii over the 20 - 25 March. Additionally the two Kenya turtles (pictured at the top of this blog post) made under the direction of professional artist Andrew McNaughton and with help from the Umoja Curio Sellers and the Watamu Marine Association Community Waste Management and Recycling Project ended up continuing their journey around the globe. They were assisted in this migration by new friends in Hong Kong, where they will be utilized to promote community involvement with coastal beach clean-up projects planned for 2011 and 2012. These events will be planned in part by ECOZINE.  Currently the Belize and Palau turtles are being exhibited at the 31st Annual Sea Turtle Symposium on Sea Turtle Biology & Conservation in San Diego, CA.

I am so happy that so many great groups, teachers, and artists contributed to this project. And thanks to their efforts to clean up the beaches in their own backyard used by sea turtles around the globe. A good article that sums up the complete scope of threats to marine turtles can be found on the BioScience website.

The Sixth Gyre: Art, Oceans, and Plastic Pollution - Marine Debris Art Exhibit in Hawaii - 20-25 March 2011

© 2010 Pam Longobardi
The past few months have been busy planning a Marine Debris Art Exhibit for the 5th International Marine Debris Conference being held in Honolulu, Hawaii this March. In August of 2010 my collaborator Pam Longobardi a professor of Art at Georgia State University, herself a talented artist, and I submitted a proposal to organize an Exhibit showcasing the marine debris art created by a group of talented professional artists.  The conference organizers NOAA and UNEP have supported our efforts and over the last 6 months we have been putting together a wonderful collaboration of talented and internationally recognized artists. The art selected for this exhibit was produced by 7 professional artists who have devoted much of their study to both understanding and interpreting the social causes and ecological challenges of marine pollution. The collaborating artists are internationally recognized for their ability to utilize art to visually interpret the human impacts of consumption and how that impact extends to marine ecosystems. The pieces of art in this exhibit reflect that aptitude. It is hoped that this exhibit will inspire thought about the role art can play interpreting conservation issues to the public, and how art may also inspire creative solutions from viewers.

Exhibit Statement:

Seven professional artists unite to illustrate the environmental challenges marine ecosystems face due to discarded plastic. In its entirety their work guides the audience to an inescapable vantage point. One from which it is no longer credible to maintain a culpable ignorance of the impacts plastic pollution is having on our oceans as well as the wildlife and human populations dependent on them. In combining these works the viewer’s journey mirrors the path of awareness and responsibility each artist experienced through intimate exposure to this issue.

Taken together, this body of work is transformative, enabling viewers to interpret their own role in the creation of marine pollution. The exhibit integrates in situ observations with artistic innovation, and bridges the boundary in-between. The juxtaposition of powerful images of environmental tragedy alongside artistically styled works that incorporate discarded plastics prompts the viewer to identify creative measures to reduce plastic from ending up in our oceans, rather than being overwhelmed by the challenge. The viewer ultimately shifts from blaming others to taking personal responsibility, engaged with the marine environment and therefore invested in finding solutions to reducing marine pollution sources.

Over the next few weeks I will write more about these artists (and others that we could not include) and their art. Looking at both how art helps us all interpret our connection to the natural world, in this case the marine environment, and the personal journey of how these artists discovered marine debris. I have started a new blog (click on title below) to focus specifically on these topics called:

Kenya Eco-Safari with Snorkeling in Zanzibar

July is usually the time of year I start planning to lead my safari to Kenya and Tanzania. This year I will not be making the journey but I thought I would share with you some images and experiences from past expeditions. I first went to Kenya in 1987 as part of a School for Field Studies wildlife management program. It was on this program that i met one of my closest friends, Todd Palmer. Currently Dr. Todd is a professor at University of Florida, and his research focuses on ant - plant mutualisms, and more recently termite influence on ecosystem structure. I mention this only because it was with Todd that I returned to Kenya in 2002 to help teach field courses to undergraduate students. From 2002 through 2005 we led 5 separate 6-week fields programs, allowing students 3.5 weeks of experiential field based learning opportunity at the Mpala Research Center in Laikipia, 1-week of a community oriented service project, and 1.5-weeks of safari to the Masai Mara, Lake Nakuru, and on the coastal town of Watamu. It was through our experiences with these student groups that I began organizing custom safaris for Oceanic Society and private groups. Since 2004 I have been leading a variety of safaris to Kenya and Tanzania.


With our student groups we had the opportunity to participate in many interesting research projects, some specifically examining human/wildlife conflicts. In different years we have witnessed capture and radio collaring of various African predators, lions and leopards were two of the more exciting.  Now returning with ecotourists groups we have been able to have similar experiences. Unique, up close and personal encounters with nature, and at the same time efforts are made to support local and effective conservation programs in the countries we visit. Part of the fee the participants pay goes directly to a variety of conservancies that have been established to create an economic support system for conservation among local communities. Additionally groups visiting Mpala research center and Chumbe Island in Zanzibar, pay fees that directly support these research centers and their educational programs. These safaris allow the participant to connect through firsthand experiences, with conservation organizations on the ground in Kenya and Tanzania that are directly involved in community driven projects with conservation management objectives at the core of their research.

Along the way our groups share many amazing experiences. Wildlife is obviously what drew many, however it is frequently the people that we interact with along the way, who add a special intimacy to what we are lucky enough to experience. We start in Laikipia, where the largest concentrations of game in all of East Africa (outside of national parks) can be found. We visit Mpala, Ol Pejejeta, and Lewa Downs. From here we depart for Lake Nakuru and then fly to the Masai Mara arriving just in time for the height of the wildebeest migration. After a brief return to Nairobi we depart the following day to Chumbe Island Marine Reserve, off the coast of Zanzibar. After all the dust of safari, it is great to spend three days snorkeling along Chumbe's protected coral reefs and learning about the coastal ecology of Africa.
I hope you might join us on a future safari, please feel free to contact me for more information. In the meantime click on this link for a slide show from last years safari. I am planning two summer eco-safaris for 2011. In future posts I will include more details about specific parts mentioned above.
