Little America-Victoria Land Traverse 1958-1959


Map: DenHartog and Wilson, 1959, Plate 1.

Station Information: DenHartog and Wilson, 1959, p.22-105. Info for Station 83 and 84 found in Crary, 1963, p. 99. Latitude and Longitude reported in decimal degrees. Elevation and depth reported in meters.

Temperature and Depth: Temperature reported in Celsius, depth is in meters. Temperatures were taken with a thermohm and Wheatstone bridge. Accuracy of temperature is no worse than 0.05C. Temperatures for stations 56-60, and 85-87 are taken from Crary et al., 1962, p. 125. Temperatures for stations 70-84 are taken from Crary et al., 1963, p.31. Temperatures for stations 61, and 66-69 are taken from Kojima, 1964, p. 216-217.

Density: "The densities were measured with SIPRE 500 cc tubes with rubber end caps." "The main cause of error in the density was the inaccuaracy of the spring scales which often gave readings that differed by as much as 3 grams." "The deviation of the density from the average value was found to be + or - 0.005 gm/cm3" (DenHartog, p. 3). 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. Source: Bentley, C.R. et al., 1964, (Plates 6 and 7, bar graph).

Accumulation: Accumulation reported in cm of water equivelant.

* 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. Density values for stations 69-82 from Crary, 1963, p.32. Density values for stations 51-60, and 86, 87

*** Density at depth. Values for stations 69-82 from Crary, 1963, p. 32.
