A day in the life of the East Island Exiles

How we stayed sane on the smallest island field camp in the Northwestern Hawaiian Islands

by Marylou Staman

Imagine this: You wake up on a cot, under a canvas tent, and blink your eyes, wondering where you are. As you remove your ear plugs, the dull sound of birds nesting under your tent becomes a cacophony of screams, honks, and wails, and the afternoon sunlight streaming through gaps in the tent walls burns your eyes. It’s hot, you’re exhausted, and yet you smile, because you finally remember that you’re on East Island, and in the middle of the greatest adventure of your life.

East Island, our home for the majority of our summer up at French Frigate Shoals in the remote Northwestern Hawaiian Islands, is only about 2000 feet long and 400 feet wide. Because of its size and our initial impressions from satellite images, we originally dubbed our future home a “sand bar,” devoid of life. But upon closer inspection we found the island to be rich with birds, Hawaiian monk seals, vegetation, and of course, sea turtles. Even the beautiful turquoise water surrounding the island, our front yard, provided us with daily sightings of schooling trevally, foraging eagle rays, and huge tiger sharks, patrolling the shallow lagoon waters for disoriented albatross fledglings that landed on the water while learning how to fly. With the gorgeous scenery and wildlife keeping us company every day, it was easy to fall in love with our tiny island home.

But what brought us to East Island? My husband, Jan Willem Staman, and I, along with our colleague Alex Reininger, made up the three-person Sea Turtle Research Team in the Northwestern Hawaiian Islands with the NOAA Fisheries Marine Turtle Biology and Assessment Program. It was our job this summer to set up a camp on East Island and study the hundreds of sea turtles that come to this small island to reproduce. While it is not known why approximately 96% of Hawaiian green sea turtle nesting takes place at French Frigate Shoals, we are learning more and more about this phenomenon with each passing field season. This season, we identified 871 individual male and female turtles with a small white number we gently painted onto their shells. On East Island alone we counted 413 females that came up to nest this season, more than last year’s 87 but less than the banner year of nearly 900 in 2014 (because turtles nest every few years, every population has natural seasonal highs and lows depending on which turtles decide to make the migration and nest). Along with numbering each turtle, we also gave each one small flipper tags and took their measurements to track their growth. Since researchers have been tagging in Hawaii for several decades already, it was exciting to find turtles that had tags from 10, 20, and even over 30 years ago!

Because sea turtles nest at night, we had to adjust our sleeping schedule to make sure that we would be awake when the turtles were most active. That meant that our work day actually started around 4pm in the afternoon. Just like in the main Hawaiian Islands, the sea turtles at French Frigate Shoals would haul out onto the beach during the day to bask, or rest in the sun. From 4-6pm we would walk around East Island and record all of the turtles we saw based on the white numbers we wrote on their shells. On our very first day on East Island, we walked around the island and counted 229 basking sea turtles! However, that number steadily declined throughout the summer as more and more females finished laying their eggs and returned to the main Hawaiian Islands. Those females, with our white numbers still on their shells, have now been seen back around the main islands and have become a part of a unique citizen scientist project recently announced by NOAA!

After completing our afternoon survey, we would spend a few hours transcribing the data and eating dinner before starting our night survey around 9pm. While in theory walking around a deserted island at night may sound spooky, there was actually so much going on that we didn’t have time to get creeped out. In addition to the dozens of nesting sea turtles crawling out each night, we also encountered sleeping monk seals and restless birds, all lit up by the most impressive display of stars I have ever seen. When the moon was up we didn’t even need headlamps, and when the moon was set, the darkness allowed the stars to light up the whole sky instead. We spent so much time on our night surveys looking for turtles on the ground, that I’d occasionally remind myself to look up, and the night sky always took my breath away.

When the sun began to rise on the horizon, it meant it was time to do one last lap around the island and head back to the tents. After 8-9 hours of walking laps around our sandy island, the biggest and completely unanticipated challenge we faced each day was still to come: trying to sleep! Between the loud birds and the hot sun, sleeping more than 2-3 hours in a row became a notable achievement around camp and something I do not take for granted now that we’re back here in Honolulu.

Jan Willem and I returned to Honolulu at the end of August and have been busy entering all of the data we compiled over the summer. In order to collect another month of nest data, Alex bravely stayed behind on East Island alone, with daily check-ins from the nearby monk seal camp on Tern Island. Sitting behind a desk in a cubicle is definitely not as adventure-like as carefully sneaking up behind nesting turtles to count their eggs, but we do value the data and enjoy the memories it elicits.

Green Sea Turtle Nesting on Northwestern Hawaiian Islands

Meet the Northwestern Hawaiian Islands Sea Turtle Research Team
Marylou Staman (1st season) – Marylou conducted three years of sea turtle research on Guam, and only saw 30 individual nesting females.  She’s seen almost 14x that number in the first few weeks of the nesting season!
Jan Willem Staman (1st season) – Jan is making the big transition from being a full-time soccer player with the Guam national team to a turtle researcher on the French Frigate Shoals team.
Alex Reininger (1st season) – Alex has mostly known nesting sea turtles from those that strand and wash up on Oahu. She’s enjoying seeing them alive and well on their nesting grounds.

East Island

The Northwestern Hawaiian Islands sea turtle researcher team (Marylou, Alex, and Jan) arrived on French Frigate Shoals on May 30th to assess the number of nesting female green turtles because 96% of Hawaiian green turtle nesting occurs at French Frigate Shoals on East, Tern, Trig, and Gin Islands. Since then, they have identified 150 basking males and 416 nesting females. The peak of the nesting season has begun and the researchers have already seen 5 times the number of nesting females compared to the number of females seen for the whole season in 2016. So, 2017 will be a ‘whopper’ of a year, however, it is still less than our greatest nesting season with 811 nesting females on East Island (only) in 2014! Some of the turtles seen this year are turtles previously tagged on East Island during nesting events over 17 years ago and five other turtles seen this year were originally tagged during in-water captures in the main Hawaiian Islands (some as juveniles over 15 years ago)!

East Island Nesters

“Hiwahiwa” or L2 has been nesting on East Island for 15 years. Her nesting migration to East Island in 2010 was tracked with the attached satellite tag (Photo: NOAA Fisheries/Tammy Summers).

We want to highlight one particular turtle, L2, tagged by Hawaiian green turtle expert George Balazs. L2 is also known as “Hiwahiwa” – meaning precious, favorite – by Mālama Na Honu volunteers on the North Shore of Oahu. Hiwahiwa was originally found alive on Laniakea beach, Oahu with an impact lesion to her shell in December of 2001. After 11 days of rehabilitation at NOAA facilities, Hiwahiwa was released back into the wild. A few months later, in June of 2002, she was seen nesting on East Island. Since 2002, Hiwahiwa has been seen basking in the sun every year at Laniakea beach and in 2009, she was outfitted with a satellite tag so that scientists could learn more about her migration patterns. During the nesting season in 2010, Hiwahiwa was re-sighted back on East Island digging a nest (see photos with satellite tag attached). Just a few days ago, the sea turtle research team saw her digging a nest; fifteen years after the first time she was seen nesting on East Island!

The research team return to Oahu at the end of the nesting season (September) and will bring with them valuable information to determine the number of green turtles in the Hawaiian population. This data is important for designating whether the species is threatened or endangered so that we can effectively manage this distinct population of turtles.
