The National Ice Center (NIC), under sponsorship of the United States Navy, the United States Coast Guard, and the National Oceanic and Atmospheric Administration (NOAA), provides sea ice analyses encompassing the "Arctic" and the "Antarctic". These analyses continue the data set established under our previous name, the Joint Ice Center. These atlases continue the near real-time integration of remotely sensed data and point observations and differ only in the Arctic and Antarctic are split into two separate publications per hemisphere per year. This publication is the 12th edition of the annual "Antarctic Sea Ice Atlas" published in hard copy format by NIC. The atlas contains weekly charts depicting the sea ice extent and coverage in the Southern Hemisphere from the first week of January through October 1997. During the last week of October 1997, the Antarctic paper charts were replaced by digital charts in a Graphics Interface Format (GIF). Printouts of the digital GIF charts for all Antarctic regions are contained in Supplement 1 to the "Antarctic Sea Ice Atlas". Future annual atlases will be available in a digital format on CD-ROM though the national Snow and Ice Date Center (http://www-nsidc.colorado.edu). NSIDC is the official archive center for the NIC. The NIC uses a wide variety of data sources in the production of sea ice analyses. The line types used in the analyses provide metadata information with regard to sensor type. Solid lines depict boundaries derived from: point observations, Defense Meteorological Satellite Program Operational Line Scan (DMSP OLS) and NOAA Advanced Very High Resolution Radiometer (AVHRR) data. Dash-dash-dotted line depicts boundaries derived from DMSP Special Sensor Microwave Imager (SSM/I), and dashed lines depict boundaries derived from forecast models and climatology.
