Abstract:
Visible band imagery from high-resolution satellites were acquired over four Arctic Ocean sites (three in 1999) during the summers of 1999, 2000, and 2001. The sites were within the median extent of the perennial ice pack. Imagery was analyzed using supervised maximum likelihood classification to derive either two (water and ice) or three (pond, open water, and ice) surface classes. Clouds were masked by hand. The data set consists of tables of pond coverage and size statistics for 500 m square cells within 10 km square images (image resolution is 1 meter), along with the surface type maps called Image Derived Products (IDPs) from which the pond statistics were derived. A total of 101 images over the three summers and four sites were used for pond statistics, out of a total of 1056 images acquired. The images are irregularly spaced in time. Data are stored in Microsoft Excel format and ASCII text, image files are stored as GeoTIFF binary images, browse images in PNG, and JPG image files, and are available from August 1999 and generally for May into September for 2000 and 2001 via FTP.

Attribute_Accuracy_Report:
Sun angle and light levels varied, and images varied in dynamic range. This necessitated using supervised maximum likelihood classification for the best possible classification result. Producing the surface type maps was a subjective process for which no independent checks were available. Limitations include the 1 m resolution of the images (smaller ponds are not detected), and false detections because of ridge shadows. Based on earlier work (Fetterer and Untersteiner 1998), we estimate the accuracy of the pond coverage at ±5 percent. This data set cannot approach the accuracy of detailed surface observations like those acquired at SHEBA, but it does provide spatial coverage and a number of samples that would be difficult to acquire in any other way. The Excel file, Image_file_summary.xls, has a quality ranking for each image. These were assigned subjectively when the supervised classification was performed, and indicate confidence in the pond coverage statistics. Quality is ranked optimal (highest confidence in results), good, questionable (use results with care) and poor. Those ranked poor will not have surface type coverage statistics data, but may have been processed only to obtain image files that show floe morphology.
