For the third consecutive year, the ATMOS, CEOAC and REMObs projects, managed by INPE and CHM, have come together to maintain an extensive system for monitoring wave, wind and current conditions in the Antarctic region. And in this Antarctic summer of 2022/2023, with the support of the Polar Vessel “Almirante Maximiano” and the Oceanographic Support Vessel “Ary Rongel”, they expanded the data collection network in the “Frozen Continent”, with the deploying of 3 mooring buoys, in addition to data collection through oceanographic stations, deploying of wave drifters and installation of meteorological stations near the Antarctic Station Commander Ferraz. Here you can access the data collected in real time by our systems.
Managed by INPE's Laboratory for Ocean and Atmosphere Studies (LOA-OBT), ATMOS is a promising science, technology and innovation initiative aimed at improving the understanding of sea ice-atmosphere-ocean-wave interactions and the exchanges of heat, momentum (amount of movement) and CO2 at their interfaces in the Southern Ocean. It is a component project of PROANTAR and financed by CNPq/MCTI/CAPES.
Managed by the Oceans and Cryosphere Group of the Center for Weather Forecast and Climatic Studies at INPE (GOA/CPTEC-INPE), the project CEOAC (Center for Ocean-Atmosphere-Cryosphere Interaction Studies) is established since 2009 by the INCT of Criosphere, with a view to studying the exchange of heat, momentum and gases between the ocean and the atmosphere in the South Atlantic Ocean and in the Atlantic Sector of the Southern Ocean, as well as the climatic connections between Antarctica and South America. The project uses data from in situ observations, models and satellites and is funded by CNPq, FAPERGS and CAPES.
REMObs (REMO Observacional) project, a partnership between Brazilian Navy Hydrography Center (CHM) and PETROBRAS, contemplates a joint effort for the development and consolidation of a National Metocean Buoy (BMO-BR). And for that, it also foresees the establishment of an operational data collection network in the South Atlantic, a factor of great importance for the calibration and validation of metoceanographic forecasting models.
And this year we also have the support of companies HIDROMARES, which integrated and is responsible for managing the data of the Criosfera buoy, and SOFAR, which has a three-year partnership with CHM and INPE to deploy wave drift buoys on the Drake Passage.
The field work on these projects was only possible thanks to the support of the Brazilian Navy, Petróleo Brasileiro S.A. and the National Petroleum Agency (ANP)
