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.
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.
At the turn of the millennium, the origin of leatherback turtles in California waters was unproven. Many assumed they originated from nesting beaches in Mexico or Costa Rica; few could have imagined the extent of their travels across the entire Pacific Ocean. We know now that West Pacific leatherbacks only make their epic trans-Pacific migration about every three to five years. Unfortunately, the batteries on early satellite tags didn’t last long enough to track their whole migration.
Amidst the Coronavirus shutdown, citizen scientists quarantining on their sailboats in Mexican waters continue to report their sea turtle sightings via Upwell’s Sea Turtle Spotter project. The sightings reported by the citizen scientists are astonishing. Following on these reports, Upwell’s resident researcher in Mexico, Stephanie Rousso, arranged with a local pilot to take to the sky for a bird’s eye view of sea turtle distribution around the southern end of the Baja California Peninsula.
Inspired by Upwell’s collection of citizen science data to advance protections for sea turtles at sea, three biologists--informally dubbed “the turtle girls”--resolved to join the caravan of boats on the Baja Haha sailing rally to teach sailors and cruisers how to identify and report sea turtle sightings during the Baja Ha-Ha.
