The Endangered Leatherback Turtle: A Study of its Ecology in the California Current

As a ⁤postdoctoral researcher at UCSC-NOAA Monterey, my focus has been on studying the ecology of⁢ one of the ⁢most threatened species in the California Current (CC), the​ leatherback turtle (Dermochelys coriacea). My previous research on bycatch in tropical fisheries has given me first-hand knowledge of the daily threats faced by leatherbacks. During my postdoctoral career, I had the opportunity to conduct fieldwork⁤ in ‍Baja California, Mexico, which sparked​ my ⁣interest in researching marine turtles in the Gulf ‍of⁤ California. The ⁤migratory patterns, foraging habits, and vulnerability⁢ of these creatures to fisheries and climate change make them a fascinating subject for study.

Improving the Leatherback Turtle Model

During my time in Monterey, I worked with ⁣Scott‌ Benson (NOAA Southwest Fisheries Science Center) to analyze tracking data collected over several years. Our goal was to update and enhance an existing leatherback turtle model created by Heather Welch in 2019 (Welch‍ et ​al., 2019). This model uses Species Distribution Models (SDMs) ‍to predict ⁢the presence of leatherbacks in the California‍ Current and identify areas​ of ideal habitat. By incorporating data from satellite tracks and environmental factors, this model can assist‍ resource management in making⁢ decisions to protect ​leatherbacks.

Since 2018, NOAA and Upwell’s vessel-based monitoring team have continued to tag leatherbacks, ‍collecting additional data that could improve the model.​ By validating the original ​model and incorporating new tracking data, we were able to better predict foraging areas when leatherbacks return to California waters during the summer and fall.

The Importance‍ of Protecting Leatherbacks

The ⁣leatherback turtle is an endangered species, and its population⁣ in the California Current is at⁤ risk due to threats from fisheries and climate change. By studying their ecology‍ and ⁤using advanced⁢ models, ⁤we can gain ⁣a better understanding of‍ their behavior and movements, which can inform conservation efforts. It​ is‍ crucial to continue monitoring and protecting these magnificent creatures to ⁤ensure their​ survival in the California Current and beyond.
