Map: Shimizu, 1964, p. 38.
Station Information: Shimizu, 1964, p. 42. Latitude and Longitude reported in decimal degrees. Elevation and depth reported in meters.
Temperature and Depth: Shimizu, 1964, p. 42. Temperature reported in Celsius, depth is in meters. Accuracy no worse than 0.05C. Comments on temperature measurements from Shimizu, 1964, p. 37. Temperature at 10 m was measured by a Leeds and Northrup thermohm. The time necessary for the thermohm to come to equilibrium was determined to be at least 2 hours.
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). Comments for density measurements from Shimizu, 1964, p. 37. Used CRREL snow density tubes. CRREL snow density tube is about 5.8cm in diameter, 18.9cm in length, and 500 cm3 in volume.
Accumulation: Shimizu, 1964, p. 46. Accumulation reported in cm of water equivelant. Comments for accumulation values from Shimizu, 1964, p. 40. Accumulation was determined from the stratigraphy, snow density profile, and ram hardness profile. "However, it is the author's opinion that stratigraphic interretation is subjective, especially in coastal regions of Antarctica such as the northern parts of the Antarctic Peninsula Traverse."
* 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.
