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.
Trans-Atlantic Collaboration Tracks Turtles into their Lost Years
Upwell’s efforts to learn more about the lives of juvenile loggerheads in the Atlantic expanded from Florida to the Azores, and now, to South Africa. Through a new collaboration with the Two Oceans Aquarium Foundation, Upwell Executive Director Dr. George Shillinger traveled to Cape Town for the tagging and release of rehabilitated juvenile loggerhead sea turtles. The Two Oceans Aquarium Foundations' Conservation Manager, Talitha Noble, wrote this post to provide some insights on why learning more the movements of young loggerheads at this juncture between two oceans is so important.
Following Tiny Turtles at Sea Part II: Tag Deployment
As you may have read about in our previous blog, Upwell developed prototype micro-satellite that are lighter than a penny to follow juvenile turtles at sea and learn more about the life phase known as the Lost Years. This data helps us to piece together the various routes juvenile turtles of different species and populations follow as they cross ocean basins for the first time. Read part two of our “Following Tiny Turtles at Sea” blog post to learn about how we release tagged turtles and plan to mobilize the data we collect.
Following Tiny Turtles at Sea: Tag Tech
Telemetry, also known as biologging, is when researchers use tags to follow an animal and collect data on its location, physiology, behavior and environment. This kind of data helps researchers create effective conservation strategies; for example identifying areas where an animal forages, breeds or builds its home and then reducing threats in those areas. Learn more about how Upwell is using cutting-edge telemetry tech to learn more about juvenile sea turtles in our latest blog post!

Rescued sea turtles help advance “lost years” research
Upwell recently collaborated with Dr. Terry Norton and the Georgia Sea Turtle Center (GSTC) on the release of eight rehabilitated juvenile Kemp’s ridley sea turtles. Prior to their release, each of the seven turtles were outfitted with the prototype microsatellite tags by Upwell researchers and the GSTC team.
Update from the field: The little turtle that could
In late November, 2021 Upwell deployed six prototype micro-satellite tags on juvenile loggerheads in the Azores. Despite the estimated 80 day tag lifespan, one of the solar powered tags continues to transmit over 150 days later! The tag is carried by the smallest of the group of loggerheads who was named Peniche.
