AM01 borehole drilled January 2002 at a height of 65 metres above sea level. Current meter data dips collected during routine CTD operations over a period of 4 days upon completion of borehole. Consult Readme file for detail of data files and formats.

AM02 borehole drilled December 2000. Partial annual data retrieved for 2001. Complete annual data retrieved for 2002, and 2003. Consult Readme file for detail of data files and formats. New data and readme added July 2006.

AM01b borehole drilled December 2003. Current meter data dip collected during routine CTD profiling over a period of 1 day upon completion of borehole. Consult Readme file for detail of data files and formats.

AM02 borehole drilled December 2000. Consult Readme file for detail of data files and formats. 2011-2012 data may be final data from the unit owing to battery failure. The original project for this dataset was ASAC 1164, but recent data fall under the auspices of project AAS 4096.

AM02 borehole drilled December 2000. Several caliper profiles obtained as a 'first look' at borehole closure rates. Consult Readme file for detail of data files and formats.

This dataset contains time-series of current profiles from beneath the Amery Ice Shelf obtained from an Acoustic Doppler Current Profiler (ADCP) (RDI 300 kHz broadband Workhorse) on the AM06 mooring string. The ADCP was positioned ~108 m below the base of the ice shelf and oriented to look upwards (i.e. toward the base of the shelf) to examine the water cavity boundary layer and the range (distance) from the instrument to the ice-ocean interface. Accounting for instrument displacement by ocean currents, changes in range are expected to be indicative of basal melting. The dataset contains ~1 year of velocity data from 07/01/2010 sampled at 30 minute intervals. In the vertical, the ADCP sampled 27 bins, with a measurement every 4m. Key variables in the dataset include ocean velocity (u, v, w), instrument orientation (pitch, roll, heading) and distance from the instrument to the ice shelf base (btdistance), as well as quality control parameters such as beam correlation (avbeamcor), strength of the return/echo amplitude (ampav) and velocity error (errv). Two data files are archived here, the raw data "adcp_am06_1noqc.nc" and the quality-controlled data "adcp_am06_1qc.nc". Descriptions of the quality control and post-processing are found in "readme.rtf" and notes and preliminary plots are found in "borehole2010_11.pdf".
