All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).
These aerogeophysical data were collected as part of the ICECAP (International Collaborative Exploration of the Cryosphere through Airborne Profiling) collaboration in 2015/16 (ICP7). These data were in part funded by the US National Science Foundation (grant PLR-144390 to UTIG), ACE-CRC the G. Unger Vetlesen Foundation, and supported by the Australian Antarctic Division through project AAS-4346.
This data collection represents georeferenced, time registered instrument measurements (L1B data) converted to SI units, and is of most interest to users who wish to reprocess the data. Users interested in geophysical observables should used the derived Level 2 dataset. The data format are space delimited ASCII files, following the formats used for UTIG/AAD/NASA's predecessor ICECAP/OIB project at NASA's NSIDC DAAC. Fields are described in the # delimited detailed header for each granule.
GPS provides the positioning (and timing) for all other data streams
SPUTG1B post processed 50 Hz positions; ASCII; used as source for interpolated position data in all Level 2 data streams
Magnetics provides constraints on the depth to crystalline rock, and hence indicates the density of bathymetry
SMGEO1B georeferenced total magnetic field data; 10 Hz ASCII
Repeat track laser altimetry provides a history of thinning of outlet glaciers
SLUTP1B georeferenced laser range data, no orientation corrections; 3.5 Hz ASCII
These aerogeophysical data were collected during the seventh ICECAP field season (ICP7) in 2015-16, and interpreted and processed as part of the SPICECAP project (NSF-1443690 to UTIG). They consist of 7 survey flights using a BT-67 Basler and the ICECAP aergeophysical suite. The flights were based out of Australia's Casey Station and France/Italy's Concordia Station in East Antarctica, as part of a focused survey of the 'Little Dome C', a region with a suspected 1.5 Ma ice core record.
Some issues with dropped samples on F10 and F13 with data tears and lost samples.
