IN2025_V02    - is a Marine National Facility voyage

Title: Multiyear: Integrated Marine Observing System (IMOS) Southern Ocean Time Series (SOTS) Strategic Partnership

Period: 2025-03-25 21:00 to 2025-04-14 02:30 UTC

Duration: 19.23 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-14 and SAZ-27) and then recover the existing SOTS moorings (SOFS-13, and SAZ-26).

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-14 meteorology/biogeochemistry mooring
2. Deploy SAZ-27 sediment trap mooring
3. Recover SOFS-13 meteorology/biogeochemistry mooring
4. Recover SAZ-26 sediment trap mooring
5. CTD sampling (3 cast to 4550m, 2 to 600m) at the SOTS site, including collecting samples for nutrients, oxygen, dissolved inorganic carbon, alkalinity, and eDNA analyses
6. Ship meteorological observations at SOFS buoys for comparisons
7. Deployment of BGC-Argo Float (with additional UVP sensor recently refurbished after the SOLACE float was recovered).
8. Recovery of ACC-SWOT mooring at 55S site (deployed on the FOCUS IN2023_V07 voyage).
9. Deployment of BoM drifters at site of ACC-SWOT mooring recovery; CTD cast for post-calibration of recovered sensors.
10. Carry out underway air and water sampling and sensor measurements, including bio-optics and bio-acoustics
