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.

Why the High Seas Treaty Is Important to Sea ...

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.

Tortuga laúd salvada a través de la colaboración entre pescadores e investigadores en Sinaloa

Cuando pescadores e investigadores colaboran se crean oportunidades para unir y amplificar esfuerzos orientados a la investigación y conservación de las tortugas marinas. Durante la primavera pasada, Upwell participó en estos esfuerzos proporcionando una etiqueta satelital para Liam Neythan, una tortuga laúd que fue salvada en Sinaloa, México. Nuestros colaboradores, los pescadores Edmundo Rafael Garcías Burgos y Mariano García Olivas, así como el Dr. Alan Zavala Norzagaray y el CIIDIR IPN Unidad Sinaloa fueron los protagonistas de esta historia.

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.

Striving for Mutual Success with Artisanal Fishers in Sinaloa

Striving for Mutual Success with Artisanal Fishers in Sinaloa

La Reforma sits amidst a large lagoon complex lined with mangrove trees, desert islands, and colonies of seabirds. This fishing village is one of the largest in Mexico and fishers are taking a proactive stance in protecting sea turtles from bycatch. The Upwell team recently traveled to La Reforma to meet with several experienced fishers that partner with Grupo Tortuguero, such as Captain Adalberto Garcia. The data being collected here by Adalberto’s crew is instrumental in the future of sea turtle conservation within Northwest Mexico.

Ghosts in the Bay of La Paz

Ghosts in the Bay of La Paz

The Bay of La Paz, Mexico is filled with scattered mangrove forests, rocky reefs, and rugged coastlines. Bycatch is a pressing issue in the region. Although regulations exist to limit unselective fishing gear like gillnets, enforcement can be weak. Sea Turtle Spotters help Upwell as citizen scientists, reporting both live and dead sea turtles to Upwell researchers to help us learn more about the threats they face at sea.

Upwell Teams Up with Artisanal Fishers Seeking to Reduce Bycatch

A new generation of artisanal fishers in the El Pardito fishing cooperative of Baja California Sur is working to replenish overfished stocks and reduce sea turtle bycatch. Upwell researcher Stephanie Rousso has seen first-hand the threats posed by artisanal fisheries to sea turtles, mostly by entanglement in gillnets. In collaboration with fishers from the El Pardito cooperative, Stephanie is designing a pilot program to measure and reduce sea turtle bycatch.

Sinaloa’s suripera fleet is collaborating with researchers to collect data on sea turtles and reduce bycatch in the shrimp fishery. Suripera fishers use the wind and tides to net blue shrimp in the Gulf of California.
