Resumen:
http://www.sgmeet.com/osm2012/viewabstract2.asp?AbstractID=9455 The archaeological records of the coastlines of southern Argentina and Chile  are well preserved and provide data critical to understanding the effects of climate change on humans and the marine ecosystems they relied upon. Preliminary isotopic analysis (C and N) of 270 bird and sea mammal samples from archaeological sites spanning 7000 years in both regions and samples from their modern equivalents, provide evidence of changes in the marine ecosystems through time and space. Species analyzed include southern sea lion (Otaria flavescens), southern fur seal (Arctocephalus australis), cormorant (Phalacrocorax sp.), penguin (Aptenodytes patagonica and Eudyptes chrysocome), gull (Larus dominicanus), and human (Homo sapien).
