Session 6. Environmental contaminants in marine ecosystems: Seabirds and marine mammals as sentinels of ecosystem health

Co-Convenors: Peter Ross (Canada), Hideshige Takada (Japan) and Yutaka Watanuki (Japan)

Invited Speakers:
John Elliott (Science & Technology Branch Environment Canada)
Atsuhiko Isobe (Ehime University, Japan)
Andy Sweetman (Centre for Chemical Management, Lancaster University, UK)
Hideshige Takada (Tokyo University of Agriculture and Technology, Japan)
Rei Yamashita (Tokyo University of Agriculture and Technology, Japan)

Urban and industrial developments in the world’s coastal regions have led to the release of a large number of pollutants (heavy metals, POPs, plastics, oils, radioactive substances) into the marine environment. In some cases, these have detrimental effects on variety of marine resources in coastal and offshore areas. It is increasingly important to identify sources, subsequent transport through marine physical systems and resulting spatial patterns of these anthropogenic stressors. Compared to river-lake systems, knowledge of anthropogenic stressors in marine systems is less understood due to difficulties with detection over wide areas and in offshore regions. As top predators, such as many marine mammals and seabirds, bio-magnify some of these pollutants, these organisms can be used as bio-indicators of coastal, marine and/or food web contamination. The utility of these ‘sentinels’ was discussed at the PICES-2011 MEQ Workshop. This session will: 1) identify spatial patterns and geographic areas of concern (high concentrations) of pollutants or other stressors in the PICES region using bio-indicator species, 2) examine mechanisms of transport, and ultimate disposition, of contaminants in marine ecosystems, and 3) discuss health risks for certain predators and human consumers. Review papers, case studies, and innovative methods papers on anthropogenic stressors in marine predators are invited, as well as papers that distinguish between the effects of natural and anthropogenic stressors. In particular, studies linking predator habitat use with spatial aspects of stressors in the environment and in predators are encouraged.
