First Leatherback Tagged in the California ...

In September 2025, the collaborative Upwell and NOAA leatherback monitoring team tagged our first leatherback in the California Current since 2022! The adult male leatherback weighing 438 kg (almost 1,000 pounds) was fitted with satellite and acoustic tags to collect critical data on movements and habitat use. Read more about what Ricky has been up to since he was tagged in September.

In late October, a collaborative team of researchers from Two Oceans Aquarium Foundation and Upwell took a boat into the swift Agulhas Current, the southwest boundary current of the Indian Ocean that runs down the east coast of South Africa. There, they released 12 tiny loggerhead turtles with satellite tags attached to their carapace (top shells) in an effort to understand how these turtles are using this oceanic highway. See where these turtles have traveled over their first weeks in the ocean!

Nuno Vasco Rodrigues is a Marine Biologist and researcher at MARE IPLeiria. He was named “Conservation Photographer of the Year” by Ocean Geographic Society in 2021. For the past three years, Nuno has photographed Upwell’s work tagging juvenile loggerhead turtles in the Azores Archipelago in partnership with the COSTA Project and the University of the Azores, which is part of Upwell’s Lost Years Initiative. Nuno took some time to chat with us about the highlights and challenges of documenting sea turtle releases underwater.

Researcher Interview: Analyzing Data from ...

With a team of collaborators, we tested new specially-designed prototypes of Lotek microsatellite tags on 160 juvenile sea turtles of four species in the North Atlantic. The data from these tags was published in a new article, "Novel Microsatellite Tags Hold Promise for Illuminating the Lost Years in Four Sea Turtle Species." We sat down with lead-author Tony Candela to talk about this article, his process as lead-author, and the important implications of these findings for the bio-logging community.

Leatherback Saved by Fisher-Researcher ...

When fishermen and researchers collaborate, they create opportunities to amplify efforts for the research and conservation of sea turtles. This past spring, Upwell participated in these efforts by providing a satellite tag for Liam Neythan, a leatherback sea turtle that was saved in Sinaloa, Mexico. Our collaborators, the fishers Edmundo Rafael Garcías Burgos and Mariano García Olivas, as well as Dr. Alan Zavala Norzagaray and the CIIDIR IPN Unidad Sinaloa are the key collaborators and heroes in this story.

A Brief History of the Sheila B. Research Vessel

Since 2021, John Douglas has worked with Upwell as captain of the Sheila B. research vessel while monitoring for leatherback sea turtles in the Pacific Northwest. The Sheila B. is a boat that has been specially engineered for the research work that it carries out. In this blog, John gives us insight into its history and its evolution into the perfect vessel for leatherback sea turtle monitoring.

Update from the field: The little turtle that could

In late November, 2021 Upwell deployed six prototype micro-satellite tags on juvenile loggerheads in the Azores. Despite the estimated 80 day tag lifespan, one of the solar powered tags continues to transmit over 150 days later! The tag is carried by the smallest of the group of loggerheads who was named Peniche.

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.
