As a continuation of two years of research on the elusive, critically endangered oceanic whitetip, we made the crossing to the southern tip of Cat Island on Tuesday, May 7th with the goal of learning more about this understudied, and historically abundant, pelagic shark. We have been at Cat Island for less than a week and have been extremely successful. With 17 satellite tags on oceanic whitetips and countless in-water experiences, the first leg of the trip has gone smoothly. We have over a week left here and less than ten tags to deploy, making our main purpose to put out sat tags on males and recaptures, as well as conduct ultrasounds on all females to determine reproductive state. We have also caught, tagged, and taken biometrics on a blue shark and a small but curious tiger shark while out in the blue water. To learn more, check out the link to our collaborator's blog at the Stony Brook University School of Marine and Atmospheric Science :http://www.somas.stonybrook.edu/research/highlights/Chapman/index.html We'll be sure to update you on our expedition over the next few weeks as we transition into the next phase of the project where we aim to identify vital nursery grounds for juvenile sharks in The Bahamas and deploy satellite tags on the endangered sawfish and great hammerhead.
