Western Antarctic Seas: From Trace Metals to Trophic Levels I
Session ID#: 9633
Session Description:
Western Antarctic Seas are some of the most productive on earth. Therefore, it is no surprise that they have been the focus of numerous studies over the past several decades highlighting the importance of this region to the Southern Ocean and global elemental cycles. Western Antarctic Seas support a highly productive and diverse marine ecosystem that is strongly driven by seasonal shifts in micronutrient and light availability. Although mostly isolated from many of the direct anthropogenic influences in temperate regions, these seas remain highly susceptible to seasonal and climatic environmental change. This session invites research that is focused on changes occurring in the Western Antarctic due to disruptive singular events or changes over seasonal, annual or decadal (climate change) time scales. We encourage a variety of research topics including observational and manipulative studies spanning from trace metals to trophic levels. Abstracts may encompass the response of organisms to change at the physiological level and impacts of change on the structure and function of the Western Antarctic ecosystem.
