Earth gravity field for ice thickness data: LGB traverses 1989-95

The Lambert Glacier Basin (LGB) series of five oversnow traverses were conducted from 1989-95. LaCoste and Romberg gravity meters were used to record measurements of the Earth's gravity field approximately every 2 km along the 2014 km main traverse route from LGB00 (68.6543 S, 61.1201 E) near Mawson Station, to LGB72 (69.9209 S, 76.4933 E) near Davis Station. Gravity readings were also obtained at 5 km intervals along a 516 km upper western offset track (50 km parallel upslope from main route) from LGBUW485 (68.6458 S, 60.0272 E) to LGBUW000 (72.6508 S, 55.9275 E).Raw data were stored as meter readings in field notebooks, transferred manually to spreadsheet files (MS Excel). Processed data were stored in spreadsheet files (MS Excel). The data available at the url below are stored in various formats.Summary data (2 km spatial resolution) can be obtained from CRC Research Note No.27 'Ice Thicknesses and Surface and Bedrock Elevations from the Lambert Glacier Basin Traverses 1990-95'.Documents providing archive details of the logbooks are available for download from the provided URL.This work was completed as part of ASAC projects 3 and 2216.Logbook(s):- Gravity Meter Log 89/90- LGBT Gravity #2 1992-93- Glaciology Gravity Readings LGBT 1990-91One of these documents has been scanned, and is available for download from the provided URL.Glaciology Gravity Readings, LGBT 1990 - 91.pdf
