Little America-Byrd Station Traverse 1957-1958


Notes

Map: Anderson, 1958, p. 4.

Station Information: Anderson, 1958, p. 5, 12-59. Latitude and Longitude reported in decimal degrees. Elevation and depth reported in meters.

Temperature and Depth: Anderson, 1958, p. 12-59, 62(graph). Temperature reported in Celsius, depth is in meters. "Temperatures taken in core holes at depth, by using thermohm and Wheatstone bridge, are considered reliable to 0.01C." (Anderson, p. 2)

Density: Density values accurate to only 0.005 g/cm3 (Anderson, p. 2). Range of Density Values for region: At 0-2 m range is 0.32-0.54. At 10 m range is 0.46-0.64, see Bentley et al., 1964, (Plates 6 and 7, bar graph). Density reported in g/cm3.

* Flag: Represents how temperature was derived. Values reported as (S) represent a single point measurement. This measurement has not been corrected for short term thermal decay or annual thermal cycle.

** Average Density for 0-2 m. Bentley et al., 1964, Plate 6.

*** Average Density at depth. Anderson, 1958, 95-252.
