Metadata record for data from ASAC Project 2393 See the link below for public details on this project. --- Public Summary from Project --- This project seeks to monitor Holocene-Quaternary variability of Antarctic bottom water outflow at a known deep pathway (east flank of Kerguelen Plateau) into a major ocean basin. Specifically, we can address the question of how sea-ice, frontal dynamics and SST variability are related to bottom-water production. Taken from the 2003-2004 Progress Report Two researchers from the ACE CRC and IASOS, Dr. Will Howard and Honours student Joanne Naylor, participated in a cruise to the Southern Kerguelen Plateau region in January-February 2004. The objectives were to carry out swath bathymetric mapping, subbottom profiling (using a 3.5 kHz echosounder), and coring, aboard the Japanese research vessel Mirai. We were successful in carrying out acoustic profiling and mapping in previously unmapped regions of the Southeast Indian Ridge and in the Labuan Basin area of Southern Kerguelen Plateau. Acoustic data have already been provided to Geoscience Australia, where these data will be incorporated into existing databases of bathymetry and bottom character of this (potential) part of the Australian Marine Jurisdiction. In addition we recovered two piston cores, one each from the SE Indian Ridge area and Kerguelen Plateau, as well as multicores (recovery of sediment-water interface). Inclement weather prevented us from recovering cores from all the suitable coring sites we identified, but we now have acoustic survey data in unprecedented detail and resolution to support future sampling efforts. The cores we recovered consist of pelagic sediments as follows: Split surfaces of archive half sections were exposed and lithological and sedimentological features were described using printed visual core description (VCD) sheets On MR03-K04 Leg 6, ODP-style nomenclature for lithological ...
