Synthesis of the Initial Scientifi c Results of the MIS Project (AND-1B Core), Victoria Land Basin, Antarctica
The ANDRILL Program successfully recovered a 1285 m-long succession of cyclic glacimarine sediment with interbedded volcanic deposits in its fi rst season of drilling from the McMurdo Ice Shelf (MIS). The MIS AND-1B drill core represents the longest and most complete (98% recovery) geological record from the Antarctic continental margin to date, and will provide a key reference record of climat...

متن کاملGeochemical variations detected with continuous XRF measurements on ANDRILL AND-1B core - preliminary results
Antarctica and especially its ice sheets play a major role in both the global ocean current system and climate. The ANDRILL (Antarctic Geological Drilling) MIS deep drilling project (McMurdo Sound, NE Ross Ice Shelf, drilled core AND-1B during austral summer 2006/2007) is located in a flexural moat basin filled with glaciomarine, terrigenous, volcanic, and biogenic sediments (Horgan et al., 200...
متن کاملDownhole Measurements in the AND-1B Borehole, ANDRILL McMurdo Ice Shelf Project, Antarctica
A comprehensive set of downhole measurements was collected in the AND-1B drillhole as part of the on-ice scientifi c programme defi ned for the McMurdo Ice Shelf (MIS) Project. Geophysical logs were recorded over two operation phases and consisted of calliper, temperature, fl uid conductivity, induction resistivity, magnetic susceptibility, natural gamma activity, acoustic televiewer, borehole ...
متن کاملComprehensive downhole and core physical-property measurements at the AND-1B Drillsite, ANDRILL McMurdo Ice Shelf Project
As part of the ANDRILL McMurdo Ice Shelf (MIS) Project two comprehensive sets of geophysical data were collected on ice at the AND-1B drillsite. Whole-core physical properties were determined with high vertical resolution to a depth of 1285 mbsf. A multi-sensor-core-logger was used to determine bulk density, sonic velocity, magnetic susceptibility and electrical resistivity. After drilling, a s...
