Title: SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania

Period: 2023-05-10 19:00 to 2023-05-24 22:30 UTC

Duration: 14.15 days

From: Hobart To: Hobart

Region: South Tasmania Coast; Southern Ocean

Ship: Investigator (RV) [details]

Description: The primary objective is to first deploy a new set of SOTS moorings (SOFS-12 and SAZ-25) and then recover the existing SOTS moorings (SOFS-11 and SAZ-24). 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, Continuous Plankton Recorder and autonomous glider, and potentially casts of a bio-optical sensor package.

Voyage objectives:
1. Deploy SOFS-12 meteorology/biogeochemistry mooring.
2. Deploy SAZ-25 sediment trap mooring.
3. Recover SOFS-11 meteorology/biogeochemistry mooring.
4. Recover SAZ-24 sediment trap mooring.
5. CTD sampling (2 cast to 4550m, 2 to 600m) at the SOTS site, including collecting samples for nutrients, oxygen, dissolved inorganic carbon, alkalinity, and particulate matter analyses.
6. Ship meteorological observations at SOFS buoy for comparisons.
7. Deployment of CSIRO glider for satellite calibration validation during the SWOT fast sampling phase, in support of IN2023_V07.
8. Potential recovery of BGC-Argo float, or CSIRO glider, using new recovery device.
9. Tow CPR on transit to SOTS (after the seamount survey).
10. Carry out underway air and water sampling and sensor measurements, including bio-optics and bio-acoustics.
