Session ID#: 9533
Session Description:
Areas of low oxygen have spread dramatically over the past 40 years and represent a significant ecosystem perturbation. The formation and persistence of both natural and anthropogenically induced oxygen minimum zones (OMZs) result from linkages among physical, chemical and biological processes. OMZs are spatially diverse and found worldwide in marine environments, particularly in upwelling or nutrient rich coastal systems. In these OMZs, oxygen is consumed more rapidly than it is resupplied, and declining oxygen concentrations result in a shift from aerobic to anaerobic metabolisms. This transition can result in production of potent greenhouse gasses such as methane and nitrous oxide. Thus, OMZs represent a potential positive feedback loop for global warming. This session will explore the current state of knowledge on OMZs, scaling from genes and transcripts to microbial cells and populations, and finally to whole ecosystems in coastal and open ocean OMZs. Of particular interest is work that integrates biological, chemical and/or physical data across micro to macro-spatial scales. Contributions are encouraged from biologists across all ecological levels, and from both chemical and physical oceanographers studying regions of low dissolved oxygen.
