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.
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)!
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.
