4. New approaches to conserving endangered sea turtles

Dana K Briscoe, Bianca S. Santos, Calandra N Turner Tomaszewicz, and Larry B Crowder, characterize emerging approaches to conserving endangered sea turtles across the globe. Sea turtles have declined due to direct harvest from eggs to adults, loss of nesting habitat, and bycatch in fisheries. Researchers globally have developed an extensive tool-kit to address the dramatic declines in sea turtles, and have developed focused conservation actions based on detailed understanding of the life histories and spatial dynamics leading to some success in recovering species, such as Kemp’s ridley. This chapter describes those successes and illuminates remaining challenges.

Dr. Briscoe is a Senior Data Scientist with the Woods Institute for the Environment at Stanford University. Her multidisciplinary research focuses on the integration of near real-time ocean intelligence with ML/AI technologies for marine management. She currently leads the research and development of novel data science methodologies using machine learning, image recognition, and innovative approaches to data visualization for climate-ready conservation and management tools.

PhD Candidate in the Emmett Interdisciplinary Program in Environment and Resources at the Stanford Doerr School of Sustainability at Stanford University

Bianca Santos is a PhD Candidate in the Emmett Interdisciplinary Program in Environment and Resources at the Stanford Doerr School of Sustainability. Her work focuses on integrating science, policy and society in the management of marine species in the Pacific. Utilizing both natural and social science tools, her research applies interdisciplinary methods from the fields of marine science, ocean governance and policy, and environmental decision-making. Prior to Stanford, Bianca served as an International Activities Analyst as a 2018 National Sea Grant Knauss Marine Policy Fellow in NOAA Research’s Office of International Activities. She also worked with the Food and Agriculture Organization of the United Nations to support issues related to spatial marine management. Bianca holds a B.S. in Marine Vertebrate Biology from Stony Brook University and a M.S. in Marine Science from the Virginia Institute of Marine Science.

Calandra N Turner Tomaszewicz is Research Biologist at the SWFSC in the Marine Mammal and Turtle Division, as part of the Marine Turtle Ecology & Assessment Program. Her work primarily focuses on the life history, demographics, and population ecology of sea turtles; but also includes collaborative work on marine mammals. Her research combines several tools and techniques – both in the lab and the field – to recreate multi-year life history and habitat use patterns of sea turtles to help guide management policies and inform population assessments. Cali conducts in-water research with the MTEAP team, in addition to lab-based work, most commonly skeletochronology and chemical analysis, to help answer questions related to age, movement, habitat use, foraging patterns, growth, health, and maturation rates. Skeletochronology, the study of bone growth layers, is one primary tool used to generate age-specific data on sea turtles. Other tools include chemical analysis – typically stable isotope analysis – and more recently, epigenetics – to fill in more details on life history and demographics of sea turtles.
