GIS Atlas of cephalopod distribution in the Southern Ocean

The geographic distributions of many Antarctic cephalopod species are not well understood. Many may be influenced by physical factors such as water masses, ice extent or bathymetry. In this study the ability of GIS was shown to handle large amount of data from different sources, particularly cephalopod species distribution. The species distribution maps produced with GIS can be updated as soon as more data are available and can be made available via Internet. The use of GIS and Internet technology combined will allow the scientific community to have easy access to the most recent information.

In the end of the study, a total of 2497 geographic positions of 21 species of squid were obtained, combining data from 1886 (Challenger Expedition) to 1997.

The maps of the species distribution in relation to bathymetry, ocean fronts and sea-ice extent can be found at: http://www.nerc-bas.ac.uWpublic/dsd/squid-atlas.
