Metadata details
SIPEX_II_Diurnal_Snow
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
Motivation:
One of the characteristics of this voyage is that we have long ice stations which last for a few days. Taking this opportunity, we decided to examine the diurnal change of snow properties at the fixed snow pit site. Since this measurement was not included in the original plan, Time interval was a bit variable from 3 hours to 5 hours depending on the progress of the other work.
Observation items:
Snow thickness, Temperature profile (every 3 cm), Grain size, Grain shape, Snow density, Hardness, Salinity
Instruments:
Folding scales, Spatula, Thermometer, Snow sampler, Magnifying glass, Salinometer
Information pertaining to the dataset:
Time - recorded in local time
Hs - snow depth in cm
Cloud measurements - oktas
Water level - distance between snow surface and surface seawater in cm
Depth - depth of the individual layer referenced to snow/ice interface (upper column) or snow surface (lower column) in cm
Ta - air temperature in degrees celsius
DH, FC, PP, DF, RG stand for Depth hoar, Faceted crystals, Precipitation particles, Decomposing and fragemented precipitation particles, Rounded grains - according to "The International Classification for Seasonal Snow on the Ground" (Colbeck et al., 1990).
Weight - g
Mid-depth - cm
Quality
A measurement was also planned for ice station 7 (October 20-23), but the observation was unfortunately cancelled due to the backache of the observer (TT).
