Marie Byrd Land-Horlick Mountain Traverse 1958-1959


Notes

Map: Long, 1961, p. 2.

Station Information: Long, 1961, p. I3-I242

Temperature and Depth: Long, 1961, p. I3-I242. Temperature reported in Celsius, depth is in meters. "The mesurement of the 10-meter-temperature was started immediately after the coring operation was completed. The thermohm element was lowered into the hole, and the opening was covered with plywood and snow. The temperature was read several hours later; most of the readings were made after the element had been in place overnight. A Wheatstone bridge was used to make the readings. The insturment was kept inside the Snocat until time for use and was left outside only long enough to take the reading. The accuracy is believed to be + or -0.01C if the instrument does not get too cold (below -18C)." (Long, 1961, p. 7)

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.

* 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. Kojima, 1964, p. 214.

*** Density at Depth. Bentley et al., 1964, (Plate 7).
