CSIRO Oceans & Atmosphere - Hobart [details] |
| Description: | 1. To quantify changes in Antarctic Bottom Water in the Australian Antarctic Basin. 2. To quantify the evolving inventory of heat, freshwater, oxygen, CFCs, and carbon dioxide in the upper 2000 m and to infer changes in the ventilation rate of intermediate waters and ocean acidification. 3. To determine the distributions of trace metals and isotopes, their change with time, and the physical, chemical and biological processes controlling those evolving distributions. 4. To quantify cloud-aerosol-precipitation-radiation processes and interactions over the Southern Ocean and their variability as a function of latitude and large-scale context (CAPRICORN). 5. To evaluate satellite cloud, aerosol, precipitation, and surface flux products over the Southern Ocean at different latitudes (CAPRICORN). 6. To evaluate and improve the representation of these Southern Ocean cloud and precipitation properties and processes in the regional and global Australian ACCESS model (CAPRICORN). |

Steve Rintoul (CSIRO O&A) | Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry (Chief Scientist: Dr Steve Rintoul, CSIRO) The Southern Ocean has a profound influence on regional and global climate, sea level rise, and biological productivity. The project aims to discover how and why the Southern Ocean is changing, and to identify the consequences of those changes for climate, sea level and marine life. The research will help deliver more reliable projections of future climate, from models that more faithfully represent critical Southern Ocean processes; such information is urgently needed to allow Australia to foresee and manage the risks and opportunities associated with climate change. CAPRICORN: clouds, aerosols, precipitation, radiation and atmospheric composition over the Southern Ocean (Lead Principal Investigator: Dr Alain Protat, BOM) Clouds over the Southern Ocean are one of the largest uncertainties in the prediction of the future climate of the Southern Hemisphere. This study will bridge an observational gap in this data-sparse, unique region of the World assisting in understanding why climate models poorly simulate the energy balance over the Southern Ocean and improving skill of weather forecast models to simulate frontal cloud systems. This will be achieved by analysing cloud, aerosol, and precipitation observations of frontal cloud systems and associated processes using dedicated radar, lidar, and radiosounding observations from the RV Investigator and satellite platforms. |
