Summary
Abstract: The polar oceans' sea ice cover strongly modifies ocean-atmosphere heat transfer. Despite its importance, existing circulation models and large scale sea ice models include overly simplistic parameterizations of the ice thermal conductivity that are likely to contribute to significant errors in estimating ice production rates. A set of field measurements in McMurdo Sound, Antarctica and Barrow, ... View entire text

Description: Data provided here have been collected as part of the project "Measurements and Improved Parameterization of the Thermal Conductivity and Heat Flow through First-Year Sea Ice", OPP-0126007* and include measurements of temperature and various ice properties at selected sites in first-year and multiyear sea ice in McMurdo Sound, Antarctica in the years 2002-2004. Data from earlier installations of thermistor chains for measurements of ice temperature carried out by the New Zealand team have also been included. Data files are in Microsoft Excel format, with individual worksheets for specific cores or temperature data sets. Detailed information and comments on data sampling location etc. are provided in the files.
