Algorithm Magic: Predicting Leatherback Presence in the California Current

Nerea Lezama-Ochoa is a marine biologist working as a UCSC project scientist at the NOAA Environmental Science Division in Monterey. Her team is producing daily projections of suitable habitat for 10 highly migratory species (including leatherback sea turtles). Read Nerea’s blog about how these projections are created with accuracy and why they are helpful to conservation efforts.

Upwell Research Project Technician Sierra Fullmer shares some of her most exciting sightings while conducting aerial surveys to look for leatherbacks off of the US West Coast.

Why the High Seas Treaty Is Important to Sea Turtles

Why the High Seas Treaty Is Important to Sea Turtles

Most sea turtle species migrate and spend large amounts of their life history in areas of the ocean considered “high seas.” The high seas are the parts of the ocean that are not under the jurisdiction of any nation. In June of 2023, after almost two decades of negotiations, UN Member states adopted the Biodiversity in Areas Beyond National Jurisdiction treaty (also known as the High Seas Treaty) to provide a coherent and holistic framework for protecting the high seas. Earlier this month, Upwell Executive Director Dr. George Shillinger attended the High Seas Treaty symposium to learn more about how its implementation may impact sea turtle populations and to seek opportunities to further the protection of turtles at sea.

Press Release: Novel Research Takes Marine Conservation Tools to a New Dimension

Press Release: Novel Research Takes Marine Conservation Tools to a New Dimension

The new publication "Incorporating multidimensional behavior into a risk management tool for a critically endangered and migratory species," takes a look at how data on leatherback diving behavior can be used to improve the South Pacific TurtleWatch tool aimed at reducing bycatch.

Using Machine Learning to Understand Turtles’ Lives at Sea

Using Machine Learning to Understand Turtles’ Lives at Sea

What does a researcher studying animal behavior do when the animal they are studying takes off into the middle of the Pacific ocean? In this post, Upwell Researcher Dr. Nicole Barbour breaks down how machine learning can be used to help researchers interpret data from tagged leatherbacks to understand their behavior at sea.

Notes From The Field: Monitoring Florida’s Leatherbacks

Notes From The Field: Monitoring Florida’s Leatherbacks

At the beginning of June, Upwell Executive Director George Shillinger traveled to Juno and Jupiter beaches in Florida to catch the end of the leatherback nesting season monitoring conducted at Loggerhead Marinelife Center (LMC) and participate in ongoing collaborative research projects. Read more about those projects and meet some of the leatherbacks that were monitored this season!

Emeline McMann-Chapman is an Upwell Research Assistant. She assists with collection and analysis of stranding data on cold-stunned sea turtles on the Pacific coast. She recently had the opportunity to assist Upwell and NOAA’s leatherback tagging team in Monterey Bay.

Meeting your Heroes in a Virtual World

Meeting your Heroes in a Virtual World

Princeton student Max Gotts recently attended the virtual 40th Annual International Sea Turtle Symposium (ISTS) for the first time to present his research on nearshore mortality’s role in leatherback hatchling evolution. In 2018, Max worked with Upwell Researcher Nicki Barbour in Costa Rica tracking leatherback hatchlings. Find out more about his research and experience at ISTS.

Bon Voyage, Bumpy!

Bon Voyage, Bumpy!

In October of 2021, Upwell and our partners from the National Oceanic and Atmospheric Administration (NOAA) tagged one of the largest leatherbacks ever encountered in the California Current foraging zone weighing in at 1,419 pounds! This massive male leatherback was dubbed “Bumpy” because of the distinctive bumps on the rear of his carapace, which were likely caused by a prior ship strike. Find out more about where Bumpy has traveled.

PRESS RELEASE - Massive leatherback sea turtle satellite tagged in California waters

Upwell and NOAA Fisheries are monitoring and protecting California’s leatherbacks with satellite technology. Researchers in October captured a massive Pacific leatherback turtle off California that they had caught and released once before in 2016.
