The database integrates data on over 40 phyla and 15,419 living species. The information available includes taxonomy, distribution, habitat, depth and bibliographic references of all species. The resulting database will include this information in an organized, searchable and easy maintenance database management system that will be made publicly available through the Internet.

Although it is known that a large portion of the released oil from this second largest accidental marine oil spill in history reached the surface, to date there has been no attempt to document the surface footprint and trajectory of the released oil. Our study attempts to fill this knowledge gap using remote sensing data collected by Landsat/MSS and CZCS. Both showed the same general patterns of oil trajectory to the northwest and north, nearly parallel to the coastline of the western Gulf of Mexico (GoM) with possible oil landing on Mexican and Texas beaches. Field observations at selected beaches and islands along the coast of the western and southern GoM during and after the spill confirmed these satellite-based findings, which were also used to help in planning a recent field campaign to collect sediment samples in the southern GoM.

Eight of 12 permanently emergent islands had active seabird nesting colonies during the study period from winter through summer. Nine species of colonial seabirds nested on the islands: Masked Booby, Brown Booby, Red-footed Booby, Magnificent Frigatebird, Laughing Gull, Royal Tern, Sandwich Tern, Sooty Tern, and Brown Noddy. Descriptions of colony locations in relation to vegetation or other island features along with bird censuses and historical records are presented. These large seabird populations in the southern Gulf of Mexico appear to have remained fairly stable, and they should be surveyed on a regular basis and protected.

Past experience of coastal and marine resource management illustrates how the discontinuity on the limits of ecosystem and human subsystems can lead to serious ecological, social and economic difficulties. For example, decisions on land uses, based on limited information,
