ASPeCt Sea-Ice Cards - used for training personnel to make accurate sea ice observations from ships. Australian Antarctic Division copy

Bridge-based observations of the pack ice within 1nm of supply- or research vessels are taken on all Antarctic AAS voyages while the vessel moves. Observations of sea-ice characteristics including ice concentration, ice- and snow thickness, floe-size distribution, surface features and ice type are recorded in IceBox, the underway sea-ice data acquisition tool. The ASPeCt sea-ice cards provide background and training material to support the sea-ice observers. The IceBox data sets are quality screened before they are integrated into the historical climate record for use in process studies, satellite calibration/validation, and operational or policy advise.
