Title: SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania
Period: 2026-05-13 22:00 to 2026-05-28 22:00 UTC
Duration: 15.00 days
From: Hobart To: Hobart
Region: Southern Ocean
Ship: Investigator (RV) [details]
Description: The primary objective is to first deploy a new set of SOTS moorings (SOFS-15 and SAZ-28) and then recover the existing SOTS moorings (SAZ-27). Each of the SOTS moorings deliver 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, and underway measurements. 1. Deploy SOFS-15 meteorology/biogeochemistry mooring 2. Deploy SAZ-28 sediment trap mooring 3. Recover SAZ-27 sediment trap mooring 4. CTD sampling (2 cast to 4550m, 2 to 600m) at the SOTS site, including collecting samples for nutrients, oxygen, dissolved inorganic carbon, alkalinity, and eDNA analyses 5. Ship meteorological observations at SOFS buoys for comparisons 6. Deployment of 2 x Argo Floats ( 1 at the nominal SOTS site, and one closer to Tasmania, in water 2000m deep, on return transit). 7. Underway air and water sampling and sensor measurements, including bio-optics and bioacoustics 8. CPR and Triaxus Note: The objectives listed above are not the priority ranking, because the list is designed for efficiency, using past voyage experience, to achieve all goals.
