 Examining Sea Ice in the Southern Ocean Using ArcGIS Track: Climate, Weather and Atmosphere Author(s): Tracy DeLiberty, Cathleen Geiger, Mary Lemcke A National Science Foundation project is underway with researchers at the University of Delaware, the Australian Antarctic Division, the National Ice Center and Clarkson University to evaluate two datasets--in situ (point) sea ice thickness observations and weekly ice charts (polygon)--to ascertain their quality for use in monitoring sea ice thickness and mass balance changes in the Southern Ocean. Sea-ice thickness calculations from both datasets are temporally joined to match spatially averaged in situ observations with their respective NIC ice chart, polygon data. The uncertainties of total ice thickness for both in situ observations and NIC ice charts are propagated through the calculations. A composite product of the two datasets and their error estimates is being developed for monitoring sea-ice mass balance and validation fields for climate modeling. ArcGIS and Visual Basic are used for the analysis and data processing over the five year period of study.
