摘要

The grounding of a bulk carrier on Unalaska Island in the Aleutian Chain, Alaska, on 8 December 2004, resulted in a spill of fuel oil that affected approximately 300 km of coastline in a remote area. Initial tracking of the spill commenced at the first opportunity on 11 December using a fixed-wing aircraft to conduct low-altitude surveys during weather windows. As the volume and condition of oil remaining on the vessel was not known due to access difficulties caused by weather and sea conditions, the surveillance program was continued on a regular basis throughout the winter to monitor for possible releases from the vessel. A low-altitude helicopter survey was conducted on 15/16 December, and a map of the distribution of visible surface oil on the shoreline was produced on 17 December to provide the basis for a limited winter cleanup program. A selective ground Shoreline Cleanup Assessment Technique (SCAT) survey was carried out in January and February in key areas to support this operation and to assess the distribution, amount, and character of the stranded oil. A systematic, complete ground SCAT survey was implemented in April 2005, which covered approximately 800 km of coast, to provide information to develop the spring/summer shoreline cleanup program. As part of this spring/summer shoreline survey, Operations personnel accompanied the two teams surveying outside of the "core" area to remove small amounts of oil. This was, in effect, a "clean as you go" and a "sign off as you go" strategy to obviate the need to survey, then return to cleanup, and then to inspect the completed cleanup in the segment. A cultural resources program was integrated into both the winter and spring/summer surveys. The spring SCAT program was unusual in the context of a spill response as there was a two-month lead-time to plan and organize the field operation. Data management involved the creation of a physical shoreline character and oiling database for the winter and spring surveys that was linked to a Geographic Information System (GIS), a digital photograph library, and aerial videotape imagery.
