Hello, everyone!

When the nets come up, it’s time to sort….  Each net is processed one net time so we don’t mix up samples between one net and another.  The entire process can take anywhere from four to six hours depending on how full each cod end is.  We first identify the organisms and then they go to Nina and Natalie for data entry.  Animals are being used for multiple studies once we are back on our labs:  DNA barcoding, genetic diversity studies, stable isotope analysis, contaminant analysis and vertical distribution studies.

Here is just a sample of some unique specimens we’ve collected so far!

Dr. Heather Judkins is an assistant professor in the Department of Biology at the University of South Florida St. Petersburg. She received a Bachelors degree in Marine Affairs from the University of Rhode Island, Masters degree in Science Education from Nova Southeastern University and her PhD in Biological Oceanography from the University of South Florida. Her research focuses on understanding the evolution, ecology, and biogeography of cephalopods with a main focus currently in the Wider Caribbean. Her role in this project includes the identification of deep-sea cephalopods, examining genetic diversity, and analysis of cephalopod ecology and distribution in the water column.
