OD21A:
Autonomous Observations of Coupled Physical-Biogeochemical Properties and Processes in the Open Ocean: From the Diel and Local Scales to Climate on the Global Scale I


Session ID#: 11436

Session Description:
Profiling floats, gliders, mooring and instrumented animals were initially developed to address questions relevant to physical oceanography. Thanks to the development of miniature low-power biogeochemical sensors, these platforms can now perform mutli-disciplinary measurements over a wide range of spatial (sub-mesoscale to global) and temporal (hourly to inter-annual to decadal) scales, including in highly remote areas and harsh-sea conditions. A global robotic observation system based on these networks is thus now being progressively built which will allow reducing uncertainties in biogeochemical stocks and fluxes and detect change in underlying processes. In this context, the present session welcome submissions on a variety of topics, which include: emerging technologic developments in sensors and platforms; concepts and methods to address optimal observing design from local to global scales (e.g. OSSE); integration and fusion of multiplatform data with remote sensing  (altimetry, ocean color); use of data in initialization/validation of coupled physical biogeochemical-modeling, including science and operational aspects; fundamental science questions (e.g.  phytoplankton phenology and bloom dynamics, export, respiration, nutrient obduction, OMZs) related to coupled physical-biogeochemical processes at any scale; use of autonomous platforms data, in particular in real-time, in support of outreach activities.
