Snowpit measurements made from ice stations during the SIPEX II voyage of the Aurora Australis, 2012

Note - these data should be used with caution. 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.Table 1 Snow Pits (comma separated)Date,Location,Personnel,Comments2012-10-04,Floe 3 radiometer site,Katie,Full-depth snow density profile for evaluation of SMP data2012-10-08,Floe 4 drift mast,Katie,Full-depth snow density profile for evaluation of SMP data2012-10-14,Floe 6 buoy 1,Katie,Full-depth snow density profile for evaluation of SAMS WHOI-3 data2012-10-14,Floe 6 buoy 2,Katie,Full-depth snow density profile for evaluation of SAMS WHOI-5 data2012-10-20,Floe 7 drift mast,Ted,Snow pit to characterise snow at ice station 7 drift mast site2012-10-23,Floe 7 drift mast,Katie,Full-depth snow density profile for evaluation of SMP data2012-10-28,Helicopter buoy install,Petra,Snow pit for evaluation of SAMS- WHOI-4 buoy data2012-10-29,Helicopter buoy install,Petra,Snow pit for evaluation of SAMS- TASI2-1 buoy data2012-11-01,Floe 8,Ted,Snow pit for evaluation of WHOI-2 buoy data2012-11-04,Floe 6 buoy re-install,Ted,Snow pit for evaluation of WHOI-6 buoy data
