ME23B:
Ocean Deoxygenation: Integrating Coastal and Oceanic Perspectives in a Changing World II


Session ID#: 11319

Session Description:
Deoxygenation of coastal and oceanic waters is one of the major manifestations of global change. But there have generally been two separate schools of study - one that addresses eutrophication-induced hypoxia in coastal ecosystems and another that examines naturally occurring oceanic hypoxic zones (including oxygen minimum and limiting zones, and their shoaling into coastal habitats). Both forms are, however, predicted to worsen with increasing temperatures, are affected by surface layer productivity, and affect physiological processes, animal movement and fishing practices. In this session, we hope to bring these two groups of researchers together to develop a better understanding of the commonalities and differences in different types of hypoxic systems, and to examine where and how these realms interact. We especially encourage talks that, either individually or by clustering contributions, consider similar processes in different types of systems or examine interfaces. Contributions on predicted patterns of hypoxia, adaptation to hypoxia, and the effects of hypoxia are welcomed.
