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.
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.
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.
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.
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.
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.

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.

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!
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.
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.
