IN2026_V01    - is a Marine National Facility voyage

Title: Cook Ice Ecosystems and Sediments (COOKIES)

Period: 2026-01-02 04:00 to 2026-02-24 21:00 UTC

Duration: 53.71 days

From: Hobart To: Hobart

Ship: Investigator (RV) [details]

Description: This study has three major objectives: a) to characterise marine ecosystem composition of the Cook Glacier marine region throughout the past and into the present, focussing on warming periods throughout the last 1 million years, b) assess relationships of benthic biodiversity and population genetic signatures with productivity and ice-sheet history, and c) determine the geological and palaeoceanographic conditions that may have influenced the spatial distribution of the Cook region marine life. To achieve these objectives, we will collect bathymetry (multibeam) and sub-bottom profile data (PIs De Santis and Post), sediment cores (Multi-, Kasten, Piston Cores) for sedimentological, geochemical, paleontological and genomics investigations (PIs Armbrecht, Noble, Cordier, Leventer), imagery of seafloor biodiversity (deep-towed camera; PIs Hill and Jansen), benthic organisms (NIWA Sled; PI Strugnell), and physical (CTD, ADCP, Argo floats; PI Silvano), chemical (Trace Metal Rosette; PI Noble) and biological oceanography (CTD, underway seawater sampling) (PIs Focardi, Suter, Leventer, Noble). Due to the likely presence of sea-ice in the study area (monitored remotely by PI Lieser throughout the voyage), we will sample in our priority survey area, in front of the Cook Glacier, immediately at the beginning (January) or midway through (February) the voyage.
