This CD-ROM set contains the volume 1 Snow, Ice, and Oceans data collection. The data covers a 24 month period, 1987-1988, and all but one are mapped to a common spatial resolution and grid (1 degree x 1 degree). Temporal resolution for most datasets is monthly; however, a few are at a finer resolution (e.g., 6-hourly). This dataset contains data covering: *Global snow depth *Sea surface temperature *Weekly Northern Hemisphere snow cover *NMC/ECMWF Reanalysis sea ice

GISST, (Global sea-Ice and Sea Surface Temperature) is a gridded dataset of sea-surface temperature anomalies and sea-ice coverage fractions covering the period 1871-2003. GISST was originally developed as an extention to MOHSST that provided a globally complete SST analysis and sea-ice data. This is required to drive atmospheric general circulation models. GISST has now been superceeded by HadISST. We now recommend use of HadISST instead of GISST for all purposes. GISST is only still available in case it is needed for direct comparison with earlier work where GISST was used. GISST is no longer updated or developed. GISST SSTs are based on the in-situ data set MOHSST, infilled using Empirical Orthogonal Function (EOF) interpolation. The current version of the dataset is GISST 2.3B which was provided by the Met Office Hadley Centre.

GICE (Global sea-Ice) is a gridded dataset of sea-ice coverage fractions covering the period 1856-February 2003. The current version of the dataset is GICE23b. GISST/GICE was originally developed as an extention to MOHSST that provided a globally complete SST analysis and sea-ice data. This is required to drive atmospheric general circulation models. GISST/GICE has now been superceeded by HadISST. We now recommend use of HadISST instead of GISST/GICE for all purposes. GICE is only still available in case it is needed for direct comparison with earlier work where GICE was used. GICE is no longer updated or developed. The sea-ice component of GISST (GICE) contains known inhomogeneities, especially in the antarctic. GISST should not be used for studies of sea-ice variability. GISST sea-ice fractions are based on a mixture of charts, satellite observations and statistical interpolations. The current version of the dataset is GICE 2.3B which was provided by the Met Office.

Polar View delivers a range of environmental information services for the polar regions derived primarily from satellite imagery and data. The project aims to coordinate delivery of these information products direct to users. Services include enhanced sea ice information (charts and forecasts) as well as ice-edge and iceberg monitoring data. We also provide monitoring services for lake and river ice, snow cover maps and glacier monitoring and assessment. any services are delivered in near real time and are readily accessible via the Internet.

Temperature data were collected from a tidepool at Rothera Point, Antarctica every two minutes from February 1999 to May 2000, with the aim of documenting tidal, diurnal and seasonal variability.
