BN13B:
Multiscale Interdisciplinary Observations of Marine Ecosystems and the Biological Pump I


Session ID#: 37646

Session Description:
Variations in ocean biogeochemistry and ecology are a product of numerous concurrent processes operating over a broad range of temporal and spatial scales. Given the prominent influence of interannual and decadal climate cycles, repeated, long-term observations are essential to differentiate natural variability from anthropogenic changes in marine biogeochemical cycles and ecosystems, including the biological carbon pump; this will improve our capacity of predicting ocean response to future changes and associated impacts on marine ecosystem services. Advances in measurement techniques have opened new avenues for studying the spatiotemporal dynamics of marine biogeochemical and ecological variables,and furthered research on the underlying mechanisms of the ocean’s biological carbon pump. Coupling in situ ocean measurements with remote sensing (satellites and airborne) observations that provide a more synoptic view of the ocean offers the unique opportunity to place in situ data sets at regional scales in a global context. This session will highlight research that couples biogeochemical and ecological observations from in situ and remote sensing platforms, as well as incorporate new technological advances, with the aim of improved understanding of ocean change through a multiscale approach, and specifically towards quantifying and investigating the biological carbon pump.
