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

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.

Ember the Juvenile Loggerhead Swims out into the Atlantic!

Ember the juvenile loggerhead sea turtle was released off the coast of Florida with a microsatellite tag on October 28th, 2022. This blog is the second in a series covering Ember’s rescue, recovery, and oceanic journey.

Update from the field: Juvenile green sea turtle tagging in the Cayman Islands

Update from the field: Juvenile green sea turtle tagging in the Cayman Islands

Upwell recently partnered with the Cayman Turtle Centre on Grand Cayman Island to deploy microsatellite tags on 30 captive-reared green sea turtles of different age classes. By releasing sea turtles of different age classes from the same location at the same time, we are examining how variables such as age and size may influence the likelihood of encountering optimal foraging habitats and decreasing the risk of early mortality.

Unraveling the Mystery of the “Lost Years” in the Azores

Upwell’s Executive Director, Dr. George Shillinger, and Upwell Researcher Dr. Sean Williamson recently traveled to the Azores for the unique opportunity to satellite-tag juvenile loggerheads being rehabilitated at the Aquário Porto Pim before their release into the North Atlantic.

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.

Local Gifts Can Help Turtles This Holiday Season

Local Gifts Can Help Turtles This Holiday Season

We all know buying local reduces carbon emissions and can help combat climate change, but did you know it can also help reduce threats to sea turtles? International shipping often relies on the use of massive cargo ships to transport goods across our oceans. Sea turtle migration paths can intersect with vessel traffic and nearshore shipping lanes can overlap with important foraging habitats.

Novel tracking technology sheds light on leatherback “lost years”

New technologies are finally shedding light on one of the greatest mysteries in sea turtle biology. Using prototype “micro-satellite” tags specifically designed to fit juvenile leatherback turtles, Upwell and Florida Atlantic University researchers released eighteen captive reared juvenile leatherbacks to track their movements off the coast of Florida and shed light on the “lost years” phase of their lives.

Studying Turtles at Sea Offers Deeper Insights

Data collected at nesting beaches give us only a brief glimpse into sea turtles’ intricate life histories. Satellite tags are one of the best tools available to collect data on sea turtle movements and behaviors in marine habitats. But where tags are deployed matters. Deploying tags at nesting beaches means we are limiting our research scope to the females within a population that are nesting in a given year.

Saving Sea Turtles with Technology

You might not think of someone behind a desk as working on the frontlines of sea turtle conservation, but Upwell’s Oceanographic Researcher, Tony Candela is doing just that. Tony is incorporating mathematics and oceanography to simulate the movements of hatchling and juvenile sea turtles to advance protections for them at sea.
