BN53B:
Linking Observations and Modeling to Better Understand Marine Biogeochemical Cycling II


Session ID#: 37828

Session Description:
Current advances in our ability to observe and measure ocean biogeochemical cycles and marine microbial dynamics have accelerated our understanding of the linkages between ecosystem dynamics, biogeochemical cycling, and climate variability. This session addresses the challenge of incorporating this new understanding of both large and small scale dynamics into numerical biogeochemical and ecosystem models. The first part of this session will tackle the challenges of synthesizing genomic, transcriptomic, and proteomic measurements in order to capture linkages between genes/proteins and the biogeochemical processes they mediate. We will then ‘scale-up’ and discuss mechanisms and predictability of biogeochemical variability in the climate system through integrated approaches of observations, data analysis and model simulations.
