Trip to Trinidad

This is the second part of Kayla Hamelin’s journal of her time working on the nesting beach with leatherbacks in Trinidad last spring. Kayla is the CSTN’s coordinator of conservation and educational outreach. You can read the first of her impressions of Trinidad here.

Notes from the Field (Trinidad, Part 2)

Everyone is incredibly friendly and welcoming here. Our meals at the guesthouse are prepared by local women, and the food has an interesting blend of Indian, Caribbean, and other flavours that reflect Trinidad’s diverse cultural history. Plus the food is tasty and hearty—perfect for field-work appetites! We have bonded with the children who spend time at the guesthouse during the day. I am affectionately called “auntie” by one in particular. We play games, and “Angry Birds” on my iPhone is a popular request. Considering how different this place is from anywhere else I’ve lived or travelled, it’s surprisingly easy to settle in and feel at home.

On our second night on the beach, we had a special task: training some of the Nature Seekers staff to deploy satellite tags. These are the same types of instruments that we have used to tag and follow Beverly, Asha and Christie. Instead of deploying them from our field boat and remotely following the turtles to the beach, we would like to do the opposite—have them deployed on a turtle here on the beach (ideally one with a history of coming up to the Canadian foraging grounds) so we can follow her in her post-nesting period.

Learning how to satellite tag a nesting leatherback turtle.

Turtle scientist, Mike James, and CSTN turtle technician, Devan Archibald, introduced the team to the equipment at the Nature Seekers office and then demonstrated how to set up the tag on an actual turtle that night on the beach. The training was successful and our tags are in good hands with the Nature Seekers. Now it is just a matter of waiting for the right turtle candidate: ideally a “CAN” turtle. The C-A-N code on a turtle’s flipper tags indicates she was tagged by us in Canadian waters. We might even find a turtle with a Canadian connection during this trip and be able to take part in the tag deployment!

We have worked with a good number of turtles so far and have been happy with the progress of our work. We have also encountered an adorable possum by the edge of the forest; watched bioluminescent microbes flash their blue-ish light as we disturbed the mats of seaweed on the beach that harbour them; and taken a “snack break” to sip coconut water straight from the fruit. I can’t wait to see what the coming days (and nights!) have in store.

Trip to Trinidad

At this time of year, we are deep into planning for our upcoming turtle season on the field boat and at the Sea Turtle Centre. But our minds are also full of thoughts of the nesting beach. We’re wondering what is happening in those many countries where Canadian sea turtles come ashore to lay their eggs. Last year around this time, a team from the CSTN was down in Trinidad on Matura Beach working with our friends from Nature Seekers. Kayla Hamelin, who is the CSTN’s coordinator of conservation and educational outreach, was one of the members of that team. She kept a record of her experiences in Trinidad that we want to share with you over the next few blog posts.

Notes from the Field (Trinidad, Part 1)

After several months of exceptionally brutal winter at home in Halifax, we stepped out of the airport in Port of Spain, the capital of Trinidad, into a completely different world. After adjusting to the intense humidity, I was struck by the landscape. Even from the arrivals door, a backdrop of dark green, rolling mountains loomed not too far away. A short drive later, we arrived at Suzan’s Guest House in Matura, our accommodations for this trip.

This has been my first time spending time in a tropical country, and as a biologist I have been struck by the amount of life that is here in terms of both biomass and biodiversity. It is lush and green… and loud! Thick foliage surrounds us and there is a near-constant cacophony of songbirds and cicadas (not to mention the neighbour’s rooster!). I spend time watching small green lizards climb across the cement patio below, and chattering flocks of parrots fly by each evening. I can see coconut, banana, mango and lime trees from our balcony.

But of course the ultimate reason we are here is found a little way outside of the village of Matura at Matura Beach. This is where leatherback turtles haul themselves out of the ocean to lay their eggs. Something that makes field work on the nesting beach different from our work in Nova Scotia is that it happens at night. Typically, in Canada, when we go out on the boat to conduct our research with leatherbacks at sea, we get up very early in the morning and work throughout the day. Instead, here, our work begins after sundown. We arrived in Trinidad after an overnight flight, and although we tried to rest during the day, I was glad to have a boost of adrenaline keeping me alert as we headed out for our first night on the beach. I was really excited to see my first nesting sea turtle.

The night began with an introductory meeting with our collaborators from Nature Seekers. The Nature Seekers monitor the leatherback nesting beach and guide eco-tours to see the turtles. After deciding on a game plan for the night, we took an entertaining drive down the twisty, bumpy road to the beach. On top of having to “drive British” (in the left lane, with steering wheel on the right and gear shift on the left), we had to dodge a couple of bold local dogs and, even a loose horse that crossed our path (“I thought it was a moose!” quipped the Cape Bretoner on our Canadian research team). We finally arrived at the parking lot. Bats swooped overhead as we headed down a gravel path to the beach.

The beach itself is an amazing sensory experience; the salty smell of the sea wafts over you as incredibly rough surf pounds the beach. The humidity and the sea spray create droplets that are visible in the beam of your headlamp. Behind the sand there is thick forest, and I was particularly struck by the beauty of the arching palm trees silhouetted against the starry indigo sky. We walked for a fairly short distance when our Nature Seekers guide, Randall, said to me: “You’re going to see your first nesting leatherback tonight!” Then he pointed.

A massive turtle was just ahead of us in the sand. I would have walked right by if he hadn’t said anything! There are many large heaps of dark seaweed clumped on the beach and the animal’s black hulk blended right in. She was “body pitting,” moving her body around and digging with all four flippers, settling into the sand and selecting the best spot to start digging the nest cavity. Eventually she concentrated on digging the hole for her nest, and then began depositing her eggs. It was incredible.

Kayla and her first nesting leatherback turtle. The light near the turtle’s head is red from the headlamps of people nearby. People use red light on the beach instead of white light because it does not disturb the turtles while they nest.

Despite two seasons at CSTN on the turtle boat working with dozens of live leatherbacks at sea, this was a completely different experience. I can only describe it as a “circle of life” moment. All of the leatherbacks we see in Nova Scotia begin their lives in a place like this. It was surprisingly emotional to see a nesting animal that had beat the odds to survive to adulthood, and had likely swam thousands of kilometres from her distant foraging grounds to be there that night. Plus, I was witnessing an incredibly ancient process. These animals have been coming up to the beach in this same way for literally millions of years.

In Nova Scotia, our at-sea field work with leatherbacks is typically hectic. To ensure their health and well-being, we have to work with the turtles very efficiently to return them to the ocean as quickly as possible. But on the nesting beach, things are much slower. It takes leatherbacks about two hours to complete the nesting process. This gives us a lot of time to take in the experience. We do most of our tagging, morphometrics, and injury assessments (“working up” the turtle) while the turtle is laying her eggs, when she enters a trance-like state.

After soaking in my first experience with a nesting turtle, we got down to business, working up this turtle, and several others that we found further along the beach. It was a successful first night.
