IN2016_E01    - is a Marine National Facility voyage

Title: East Tasman Plateau – key to unravelling the onset of the Antarctic Circumpolar Current, MNF Equipment Sea Trials

Voyage details on MNF site: https://mnf.csiro.au/en/Voyages/IN2016_E01

Period: 2016-08-17 to 2016-08-21

From: Hobart To: Hobart

Region: East Tasman Plateau, Storm Bay,

Ship: Investigator (RV) [details]

Description: Scientific Objectives: 1) Dredge volcanic and sedimentary rocks to obtain new, rigorous age and paleo-depth constraints for the Cascade Seamount. Underway bathymetric data will be used to refine dredge targets. 2) Collect sediment cores across a depth transect to enable work investigating paleo-oceanographic conditions using proxies. Preferably at least a multicore proximal to IODP site 1172, and piston cores at the mid- and shallow-depth sites. 3) Collect high resolution swath bathymetry and sub-bottom profile data to see how far recent sediment flows extend from the Cascade Seamount towards IODP site 1172, to test the hypothesis that downslope transport resulted in the observed sediment patterns in core 1172. Existing coverage and resolution of bathymetry across the East Tasman Plateau is insufficient to resolve this question. 4) CTD to complement the sediment core data if possible. Alternative is for clean underway surface supply samples to be taken where CTD not possible.

Caveat: this event log was authored on the voyage using a standalone logging system called ELOG which has no linkages to any underway or GPS data feeds. For this reason, some positions are unknown and may be resolved using the logged time and the underway dataset for the voyage.
