The ASPeCt data archive published by Worby et al. (2008), contains data from 83 voyages and 2 helicopter flights for the period 1980 - 2005
This file contains each individual ship-based observation, including characteristics of Primary, Secondary and Tertiary ice types and snow cover.
This file contains a sub-set of the full data archive. Observations less than 6 nautical miles from the previous observation have been removed.
This file contains summary statistics, including mean ice and snow thickness, for each individual ship-based observation in the data archive
This file contains summary statistics, including mean ice and snow thickness, for a subset of the full data archive. Observations less than 6 nautical miles from the previous observation have been removed.
Use of these data is unrestricted; however the following acknowledgement should be used in any paper making use of the data: “The ship-based sea ice and snow thickness data were provided by the SCAR Antarctic Sea Ice Processes and Climate (ASPeCt) program (aspect.antarctica.gov.au)”
A full description of the data quality control and processing can be found in Worby et al (2008).

Data Portal for In Situ Measurements of Sea Ice and Snow Properties
The Australian Antarctic Data Centre now archives in situ data on Antarctic sea ice and snow cover properties. This includes data from thickness transects across ice floes, snow pits and ice cores.
Data from Australian, Japanese, German and US expeditions are currently available. Data can also be contributed online using the excel proforma available from the site.
