Filchner Ice Shelf (Ellsworth) Traverse 1957-1958


Notes

Map: Aughenbaugh et al., 1958, p. 3.

Station Information: Aughenbaugh et al., 1958, p. 44-48. Latitude and Longitude reported in decimal degrees. Elevation and depth reported in meters.

Temperature and Depth: Aughenbaugh et al., 1958, p. 52-154. Temperature reported in Celsius, depth is in meters. Accuracy of temperature is no worse than 0.05C. "Temperatures below three meters were obtained with a thermohm element and are quite accurate" (Aughenbaugh et al., p. 43)

Density: 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.

Accumulation: Taken from Bentley et al., 1964, (Plate 4). Accumulation reported in cm of water equivelant.

Station 6 temperature taken on underside of crevasse bridge, Aughenbaugh et al., 1958.

Ellsworth Station: Temperature p. 40, density p. 26, Aughenbaugh et al., 1958.

* 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, (Plates 6 and 7).

*** Density at 10 m. Bentley et al., 1964, (Plates 6 and 7). Densities in parenthesis are aprroximations.
