BN010:
Impacts of animals on nutrient, oxygen and carbon cycling


Session ID#: 28768

Session Description:
Ocean biogeochemistry is often considered to be driven by the interaction of microbes with the physical ocean circulation, but animals can play important roles as well by: modifying microbial populations through trophic cascades; by consuming, modifying and producing organic particles; and through the direct transport of chemicals within their bodies via swimming. These effects may have significant, but widely unrecognized implications given the modification of ecosystems by fishing, climate change, or other human activities. We invite a broad range of contributions that explore, quantify, or otherwise constrain the biogeochemical impacts of animals larger than 2 mm. This could include observational studies from the field, laboratories, or paleoceanographic reconstructions, as well as modeling studies of any scope or complexity.
