Science Spotlight

In the fall of 2016, ASLC staff Dr. Markus Horning, Renae Sattler, and Dr. Pam Tuomi partnered with the Polar Ecosystem Program from the National Oceanographic Atmospheric Administration led by Peter Boveng and Shawn Dahl to capture and tag harbor seals along the Western Aleutian Islands.  The field deployment was a huge success with a total of 35 seals captured across 7 haul outs in the central and western Aleutian Islands.  In addition to the biological samples collected from all seals for independent NOAA studies, ten seals were selected for LHX tagging.  Surgical implants went swimmingly and currently all LHX tagged animals are alive and collecting data as you read!
