Title: SOFS Recovery
Period: 2025-07-01 00:00 to 2025-07-05 23:00 UTC
Duration: 4.96 days
From: Hobart To: Hobart
Region: Southern Ocean
Ship: Investigator (RV) [details]
Description: The primary objective is to recover the top section (surface float and instrumented wire directly below) of the SOFS-14 mooring, which was deployed on IN2025_V02 and begun drifting outside of its watch circle in May. The second priority is a recovery of the lower section of the SOFS-14 mooring, the feasibility of which will be assessed upon recovery of the surface float, and in discussion with the shore-based SOTS team. The recovery will follow the standard SOTS procedure, with required modifications depending on how much wire is attached to the underside of the float. It may be possible to do back-to-back operations (first the float, then the bottom section), but this will depend on both the weather and the fatigue of the deck crew and will be considered at sea and in consultation with the bridge and voyage management team. Should time and weather permit, there is approval for trying to complete the EM124 Backscatter Calibration at the Tasman Rise on the return to Hobart. This will require a CTD (1200m) for a full water depth velocity profile to support the calibration. 6hrs is budgeted for the work. The assessment for this shall be taken onboard, once the full extent of the mooring recovery is understood and underway.
