"Does Climate Change Affect Levels of Pollutants in the Arctic?"

Hosted by Bren Professor Oran Young

 

Abstract

High levels of persistent organic pollutants (POPs) have been documented in seabirds and marine mammals from the European part of the Arctic. These pollutants are transported to the Arctic mainly by ocean currents and the atmosphere from the south. In such top predators as polar bears, the arctic fox, glaucous gulls, ivory gulls, and great skuas, the levels of POPs exceed levels that affect hormone-, immune- and enzyme systems. In an International Polar Year project (COPOL-Contaminants in Polar Regions), we have studied how man-made contaminants influence marine ecosystems of polar regions in order to document climatic-change-imposed alterations of marine food webs. In this talk, I will present our knowledge about POPs in the Arctic and how climate change will influence the contaminant load on the marine ecosystem in the years to come.

Biography

Geir Wing Gabrielsen is an ecotoxiclogy coordinator at the Norwegian Polar Institute. He is also a professor in biology and ecotoxioclogy at the University Centre in Svalbard (UNIS). His research focus on the marine ecology, physiology and ecotoxicology of Arctic seabirds. During the last 10 years he have mainly worked on effects of persistent organic pollutants (POPs) on marine- seabirds and mammals.

NOTE: Research colloquia are hosted by Bren faculty members and are generally high-level talks about research in a particular area of environmental science and management.
