This data set consists of 518 tissue samples obtained from four species of|
Antarctic pack ice phocid pinnipeds (Weddell seal, Leptonychotes weddellii;
crabeater seal, Lobodon carcinophaga; Ross seal, Ommatophoca rossii; leopard
seal, Hydrurga leptonyx) collected during a research cruise in the Ross Sea
aboard the NSF Icebreaker "Nathaniel B. Palmer" from December 1999 through
The objective of the study was to document the patterns of molecular genetic
variability at important immune system loci (major histocompatibility complex =
MHC) in the four phocid pinnipeds that live in the Ross Sea. A basic
description of the multi-disciplinary cruise that supported this research was
