Mission: Leatherback Sea Turtle Research
Geographical area of cruise: California
Date: September 1, 2008
The second week has been absolutely fabulous as we found a leatherback – in fact we found three!!! This week has been all about the turtle: from identifying the biotic and abiotic conditions that define leatherback turtle habitat and foraging grounds, to tracking and tagging – we’ve done it all.
• Abiotic oceanographic data provided by scientific instruments such as XBTs (expendable bathythermographs), CTD (conductivity, temperature and depth), and water samples containing nutrient data to characterize the abiotic foraging habitats of the leatherback turtle.
• Net tow samples characterized the biotic conditions such as the jellyfish species prevalent in the turtle diet: moon jellies, sea nettles, and egg yolk jellies.
