| Objectives and Narrative |
CUSTARD #3 - Carbon Uptake and Seasonal Traits of Antarctic Remineralisation Depth - mooring recovery.
DY112 took place on the RRS Discovery, departing Punta Arenas, Chile on 16 January 2020 and returning to Punta Arenas, Chile on 25 January 2020. The science party consisted of a five-person OOI team from the Woods Hole Oceanographic Institution (WHOI), a three-person team from the National Oceanography Centre (NOC), and three technicians from the UK's National Marine Facilities (NMF). The previous cruise, DY111, was a NERC funded CUSTARD Program (Carbon Uptake and Seasonal Traits of Antarctic Remineralisation Depth, PI Adrian Martin, NOC) cruise. During that cruise water sampling was conducted in the vicinity of the OOI Surface Mooring for data validation. The primary objective of recovering the GS01SUMO-00004 Surface Mooring was accomplished. We were unable to collect shipboard meteorological data for validation of the Surface Mooring due to time and weather constraints. CUSTARD activities included underway and Go-flo water sampling. |
