Title: SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania
Voyage details on MNF site: https://mnf.csiro.au/en/Voyages/IN2021_V02
Period: 2021-04-14 07:30 to 2021-04-27 21:50 UTC
Duration: 13.60 days
From: Hobart To: Hobart
Region: Southern Ocean
Ship: Investigator (RV) [details]
Description: The Southern Ocean has a predominant role in the movement of heat and carbon dioxide into the ocean interior moderating Earth’s average surface climate. The IMOS SOTS sub-facility uses a set of two automated moorings to measure these processes under extreme conditions, where they are most intense and have been least studied. The atmosphere-ocean exchanges occur on many timescales, from daily insolation cycles to ocean basin decadal oscillations and thus high frequency observations sustained over many years are required. The current context of anthropogenic forcing of rapid climate change adds urgency to the work. The primary objective is to first deploy a new set of SOTS moorings (SOFS-9 and SAZ-22) and then recover the existing SOTS moorings (SOFS-8 and SAZ-21). Each of the SOTS moorings delivers to specific aspects of the atmosphere-ocean exchanges: • the SAZ sediment trap mooring collects samples to quantify the transfer of carbon and other nutrients to the ocean interior by sinking particles and investigate their ecological controls. • the Southern Ocean Flux Station (SOFS) mooring measures meteorological and ocean properties important to air-sea exchanges, ocean stratification, waves, currents and biological productivity and ecosystem structure. Water samples are collected for more detailed nutrient and plankton investigations after recovery. Ancillary work will obtain supporting information on atmospheric and oceanographic conditions using CTD casts, underway measurements, Triaxus towed body, Continuous Plankton Recorder and autonomous profiling Biogeochemical-Argo floats, and potentially casts of a bio-optical sensor package.
