Snowpit measurements made from ice stations during the SIPEX II voyage of the Aurora Australis, 2012
Listed in NASA Earthdata CMR
Note - these data should be used with caution.
Description
The chief investigator for the dataset has indicated that a better quality dataset exists, but the AADC have been unable to attain it for archive. In addition to snow pits dug by other groups, several snow pits were dug at IMB/AWS deployment sites and at snow mast sites.
Dates, locations, personnel, and purpose are listed in Table 1. Many of the data files include the raw weight measurements including the mass of the snow density shovel along with the snow. This needs to be corrected using the snow density shovel weight appropriate to each pit.
