title: Processed bed elevation picks from airborne radar depth sounding across East and West Antarctica (1966-1987)

description: This is a collection of all vintage BAS radar data that went into BEDMAP 1 (Lythe and Vaughan, 2001) that have not been released so far as line data. BEDMAP data descries the thickness of the Antarctic ice sheet. They have been collected on surveys undertaken over the past 50 years and brought together into a single database. These data have allowed the compilation of a suite of seamless digital topographic models for the Antarctic continent and surrounding ocean. Data are provided as XYZ ASCII line data.
description: RESPAC was the British Antarctic Survey radio-echo sounding database. It included data collected by BAS from 1966 to 1987. A number of different radar systems were used to collect ice thickness and navigation data during these campaigns. All data in RESPAC was incorporated into both the BEDMAP1 (Lythe et al. 2001) and Bedmap2 (Fretwell et al. 2013) compilations. Here we provide basic channels containing information on flight line, data-point location, and ice thickness measurements which are described in the table below. It should be noted that early surveys (prior to 1987) did not use GPS positioning, but were located using a variety of methods such as celestial navigation, inertial avionics (INS), Doppler avionics and dead-reckoning. Furthermore, various processes of "refixing" were applied to most flightlines, with distributed navigational uncertainties through the flight and at fixed points during the flight to the map-position of known landmarks. In summary, all navigational data have large positional uncertainties of up to ~5 km (Drewry, 1983). It is assumed that all radar data processing is accurate and consistent; however, we do not consider it reasonable to make estimates of change in ice thickness from this dataset without considering the potential large navigation errors, varied collection systems and processing steps. Data is available in a single file, split by the field season in which it was collected. For example, data from the 1966/67 field season will appear as L6667 (line) in the database.

description: These data represent the 1-km decimated version of the SOAR ice thickness data provided to the Bedmap2 project, collected as part of various projects between 1991 and 2001. It encompasses the Corridor Aerogeophysics of the South East Ross Zone (CASERTZ) surveys of the Byrd Subglacial Basin (BSB), Bindschadler Ice Stream (WAZ/TKD), and the upstream catchments of Kamb Ice Steam and Willians Ice Stream (IRE); targeted West Antarctic glaciology projects (IPB/WAZ/DVD/STI/LIV); corridors across the Transantarctic Mountains to South Pole (PPT) and Dome C (WLK); and a version of the Lake Vostok dataset (LVS). Data were collected as stacked log detected traces by the SOAR TUD IV system with an attached digitizer. The digitizer was significantly updated in 1997 (RTZ6). Data interpretation approaches can be found in Blankenship et al., 2001. Data is in ASCII format. Transects are separated by GMT style segment headers with the transect name. Columns are: 1. Year 2.

title: Processed bed elevation picks from airborne radar depth sounding across the Evans Ice Stream, Southern Palmer Land (1994/95 season)

description: The survey collected a total of 11,500 km of data along 22 lines, spaced 12 km apart and oriented perpendicular to the strike of both the Bouguer anomaly field, as derived from land data (McGibbon and Smith, 1991), and the major sub-ice topographical features (Doake et al., 1983). The speed of the aircraft was set to produce a sample spacing of about 60 m and the data were collected at heights between 1600 and 2000 m above sea level. The gravity signal was recorded using a LaCoste and Romberg air/sea gravimeter, S-83, which has been kindly loaned to BAS by the Hydrographic Office of the Royal Navy. The meter was modified by the ZLS company for use in an aircraft. The equipment was deployed in a BAS De-Havilland Twin Otter aircraft. Differential, dual frequency, carrier phase, GPS measurements of the aircraft's motion were made using Trimble and Ashtech geodetic receivers and antennas. Ice thickness data were obtained using a BAS-built, radio echo sounding system (Corr and Popple, 1994). Ice-bottom returns over most of the survey area were obtained at a sample spacing of approximately 28 m. GPS measurements were tied into base stations in International Terrain Reference Frame network (Dietrich et al., 1998) and gravity measurements to base stations in the IGSN71 net (Jones and Ferris, 1999). We present here the processed bed elevation picks from airborne radar depth sounding collected using the BAS PASIN radar system. Data are provided as XYZ ASCII line data.

Ice thickness data were obtained using a BAS-built, radio echo sounding system (Corr and Popple, 1994). No data from turns is included. Note that one example of overlapping, or close proximity flight lines exists and contrasting bed elevation data exists on tow line segments.

title: Processed bed elevation picks from airborne radar depth sounding across Ellsworth Land (2001)

description: During the 2001-02 field season a regional survey was flown on a 10 km line spacing grid over the drainage basin of the Rutford Ice stream (West Antarctica), as part of the TORUS (Targeting ice stream onset regions and under-ice systems) project. We present here the bed elevation picks from airborne radar depth sounding collected using the BAS PASIN radar depth sounding system mounted on the BAS aerogeophysical equipped Twin Otter aircraft. Data are provided as XYZ ASCII line data.
description: Radar data were collected using the PASIN radar echo sounding system (table 1 (Corr et al., 2007)). The TORUS survey involved the collection of a total of approximately 9,500 km of line data along 15 flights, with 10 km spacing. The airborne ice sounding radar system used a 4 μs linear frequency modulated pulse in addition to a standard short 2 μs pulse. Data provided here includes picks of surface and ice sheet bed elevation. Note a single flight may contain data from two or more SEGY files, identified in the SEGYname channel. Surface elevation is derived from radar altimeter for ground clearance &lt; 750 m, and the PASIN system for higher altitudes.

title: Processed bed elevation picks from airborne radar depth sounding across the Dufek Massif, Pensacola Mountains (1998/99 season)

description: A British Antarctic Survey Twin Otter and survey team acquired 8,300 line-km of aerogeophysics data during the Austral summer of 1998/99. Gravity and radio-echo data were acquired simultaneously with the magnetic data at a compromise constant barometric height of 2,200 m, which provides a terrain clearance of 100 m over the highest peaks. Two separate surveys were conducted; one at 5 km line spacing (tie lines at 20 km) over and stretching beyond the southern extent of the Forrestal range (main survey), and one at 2 km line spacing (tie lines at 8 km) covering the Dufek Massif (detailed survey). Ashtech Z12 dual frequency GPS receivers were used for survey navigation. Pseudorange data were supplied to a Picodas PNAV navigation interface computer, which was used to guide the pilot along the pre-planned survey lines. The actual flight path was recovered, using carrier-phase, continuous, kinematic GPS processing techniques. All pseudorange navigation data were recorded at 1 Hz on a Picodas PDAS 1000, PC-based data acquisition system. We present here the processed bed elevation picks from airborne radar depth sounding collected using the BAS PASIN radar system. Data are provided as XYZ ASCII line data.

title: Processed bed elevation picks from airborne radar depth sounding over the Jutulstraumen rift area (2001/02 season)

description: A British Antarctic Survey Twin Otter and survey team acquired 15,500 line-km of aerogeophysical data during the 2001/02 Antarctic field season along a 1-km line spacing grid with tie-lines 8 km apart. Twenty-five flights were flown from the South African base SANAE, for a total of 100 survey hours. We present here the processed bed elevation picks from airborne radar depth sounding. The airborne-radio echosounding data were collected for 5 flights, to image ice-thickness and bedrock configuration. Data are provided as XYZ ASCII line data. This high-resolution aerogeophysical survey was part of the "Magmatism as a Monitor of Gondwanabreak-up" project (MAMOG) of the British Antarctic Survey, which included new geochemical investigations, structural geology, geochronology, and AMS studies over western Dronning Maud Land.
