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.

Tagging Juvenile Loggerheads in the Bay of Biscay

Tagging Juvenile Loggerheads in the Bay of Biscay

Upwell’s Executive Director, Dr. George Shillinger, recognized that the rehabilitated early-stage juveniles at the Aquarium La Rochelle CESTM were perfect candidates for Lotek microsatellite tags and invited CESTM to join Upwell’s Lost Years Initiative, kicking off the collaboration with the tagging of 10 juvenile loggerheads in late July. Over the past two months, the turtles have shown a range of behavior, including surprisingly deep dives for turtles of such a young age!

Looking for Leatherbacks - The Web Series!

Looking for Leatherbacks - The Web Series!

Each year, the Upwell and NOAA Fisheries team conduct aerial and vessel-based surveys for leatherback sea turtles off the US West Coast. The data from these surveys can be put into action to protect the critically endangered West Pacific leatherback population. During August and September of 2024 the collaborative team documented their efforts in an engaging web series called Looking for Leatherbacks.

Taking to the Sky to Find Leatherbacks in New Zealand

Expanding efforts to monitor critically endangered West Pacific leatherbacks, Upwell is teaming up with Monash University in Australia and New Zealand’s Department of Conservation and National Institute of Water and Atmospheric Research, and our partners at NOAA to design and conduct aerial surveys for leatherback abundance in the Bay of Plenty. New Zealand has become a focus of attention for leatherback conservation and bycatch prevention, and these surveys will provide critical data to support these growing efforts.

New Collaboration to Tag Juvenile Leatherbacks in Thailand

In early April, Upwell partnered with the Phuket Marine Biological Center (PMBC) in Thailand to tag and release 11 juvenile leatherbacks, each around 1-year old. This release was the latest collaboration in Upwell’s Lost Years Initiative, an international effort to collect data on the movements and behaviors of early stage juvenile turtles.

MPAs, Swimways, and Other Protections for Migratory Marine Species

MPAs, Swimways, and Other Protections for Migratory Marine Species

Traditional conservation models identify geographic locations with important habitat and create management plans restricting human activity to conserve them. These protected areas are often important nesting, breeding, or foraging areas for highly migratory sea turtle species like leatherbacks and loggerheads, but the protections end when the turtles inevitably continue migrating. So, how can we protect sea turtles throughout their ocean habitat?
