You may remember a few years ago, that we worked in partnership with them for the Great Canadian Turtle Race. Isn&#8217;t it amazing to see these majestic animals close up?! Read on for Kathleen from CSTN&#8217;s news!<\/p>\n<blockquote><p>This is a look at life from a leatherback\u2019s point of view. That is the top of the leatherback\u2019s head you see in the foreground, with a jellyfish just beyond it.<\/p>\n<p>To us this video is amazing and fascinating.<\/p>\n<p>It was taken using a camera attached to the shell of a leatherback turtle. Dr. Mike James, who is the CSTN\u2019s scientific advisor, developed this camera in collaboration with engineers at <a href=\"https:\/\/www.xeostech.com\/\" target=\"_blank\">Xeos Technologies<\/a> and Soko Technologies. They called it Serrano-V.<\/p>\n<p><a href=\"http:\/\/journal.frontiersin.org\/article\/10.3389\/fevo.2015.00015\/full\" target=\"_blank\">A scientific paper published today<\/a> of which Mike is a co-author talks about what we\u2019ve learned with the help of Serrano-V and why it is so critical to the conservation of leatherbacks.<\/p>\n<p>As you know, we collect data about leatherbacks using satellite transmitters. This data is \u201ccoarse.\u201d It doesn\u2019t get into the fine details of what the leatherbacks are doing because it is limited by the amount and type of data you can transmit through the bandwidth of the system of satellites used to monitor the tags.<\/p>\n<p>Serrano-V allowed us to collect the finest-scale behavioural data currently available for leatherback turtles while simultaneously recording video from a camera mounted on the turtle\u2019s shell. Dr. Bryan Wallace, who is a co-author on the paper, says \u201cit\u2019s like getting turtle\u2019s home videos\u2014seeing what they see, where they go, and how they acquire vital resources to fuel their natural behaviour.\u201d<\/p>\n<p>It is just the kind of information we need to work at conserving leatherbacks in the most intelligent way possible. \u201cRather than inferring what the turtles are doing below the surface of the water, we can actually see it happening,\u201d says Mike.<\/p>\n<p><a href=\"https:\/\/canadaseaturtle.files.wordpress.com\/2015\/02\/bw_mcj.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-627\" src=\"https:\/\/canadaseaturtle.files.wordpress.com\/2015\/02\/bw_mcj.jpg?w=450&amp;h=299\" alt=\"Bryan Wallace (left) and Mike James (right) on the turtle boat off Nova Scotia.\" width=\"300\" height=\"199\" \/><\/a><\/p>\n<p>The paper is really exciting for us\u2014and particularly because Bryan and Michael Zolkewitz, the other co-author, are tremendous scientists who are as enthusiastic about this work as we are.<\/p>\n<p>What that paper can\u2019t tell you, however, is how hard it was to get this to work. This represents years of trial and error. (The project began almost a decade ago while Mike was finishing his post-doc!) There were growing pains typical of refining such a cutting-edge instrument\u2026inevitably, sometimes the camera didn\u2019t record or a sensor needed to be replaced. The camera system was also subjected to tough conditions at sea. You can imagine the impact of pounding waves, of the force of water as the turtle swam and dove. There were hours of video that couldn\u2019t be included in the analysis because the camera had shifted from its original position on the turtle\u2019s shell and the field of view we needed wasn\u2019t captured.<\/p>\n<p>Mike used to rest Serrano-V on an old white pillow in the hold of the boat to protect it from being jostled and damaged when it wasn\u2019t in use. And then when it was, he would emerge from below deck, carefully balancing Serrano-V, still on its pillow. He\u2019d climb along the side of the boat, bending under the stay wires to stand up on the bow, calling for everyone to stand back to protect the delicate antennas. It was always funny\u2014but serious, too. There was only ever one Serrano-V. There was no replacement available. And we all knew how much value the study would have if it worked.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/oBhk48Da398\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><br \/>\nI love the feeding video. It\u2019s spectacular. It seems to me such a privilege to have the chance to see what the leatherbacks are up to\u2014to be humans allowed in that private world of theirs.<\/p><\/blockquote>\n<p>&nbsp;<\/p>\n<blockquote><p>But I love this video, too. This one is from the early days of Serrano-V. You can see it on the turtle. It is slipping slightly. What is most important to me is the conversation you hear. Those are the voices of Mike and Blair and Bert Fricker, who are two of the fishermen we have worked with the longest. Blair is the captain of our field boat off Cape Breton. You can briefly hear Martin, who worked on our field team for years, and a little of me. Everyone is suggesting ways to make the tag work better. The success we are celebrating with this paper is the result of dozens and dozens of conversations like this one\u2014of lots of minds working out the small details of a big question. The value of a strong team of dedicated people.<\/p>\n<p>The other thing that a paper can\u2019t represent properly is that moment when a scientist, faced with needing information that can\u2019t be collected because of the limits of technology becomes determined to find a way to make that technology. That to me is also remarkable. That is magic. That is art as much as painting or dancing or writing. It takes courage to create something that wasn\u2019t there and courage to be tenacious season after season even in the face of a lot of \u201cfailure.\u201d It takes a great team and the ability to inspire them. So cheers to you, Mike James\u2014and to all the people who helped\u2014fishermen, biologists, engineers, CSTN staff. And thanks.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<div class=\"post-excerpt\">We&#8217;re happy to announce that our friends at the Canadian Sea Turtle Network has been having some exciting success lately with their leatherback seaturtle research.
