CSA GeoSpatial Maps Shoreline Sensitivity to Oil Spills
CSA Ocean Sciences Inc. GeoSpatial Services (GS) business line is using remote sensing and Geographic Information System (GIS) technology to map shoreline sensitivity to oil spills in the eastern Mediterranean Sea.
The Environmental Sensitivity Index (ESI) is a widely used system for ranking and classifying shoreline sensitivity based on characteristics such as degree of wave energy, potential penetration of oil into the substrate, and natural oil retention times of the shore type. This type of information is crucial to mitigate the potential impact of an oil spill.
With increased offshore energy exploration and development activities in the eastern Mediterranean, shorelines in this region are increasingly at risk of exposure to oil spills and other incidents. The challenges of security and accessibility in these countries makes traditional approaches of aerial and ground surveys difficult, particularly for the considerable length of these Mediterranean shorelines. CSA Ocean Sciences Inc. GeoSpatial Services has developed a technique to acquire, examine, and interpret high-resolution, georeferenced satellite imagery and assign ESI Shore Types to digital shoreline segments in GIS. The technique can be applied to any shoreline in the world for which an understanding of coastal environments is of interest.
Because the work occurs within the spatial framework of GIS, it enables the integration of other layers of spatial data such as sensitive resources, oil spill model trajectories, environmental sampling designs, and oil spill response plans. Once integrated into GIS, the shoreline classifications can also be made available online through a secure, web-accessible GeoPortal that is designed and operated by CSA Ocean Sciences Inc., without the need for third-party web publishing.
Keith VanGraafeiland, Director of the CSA GeoSpatial Services business line, offers, “CSA Ocean Sciences has previously completed ESI Shore Type mapping in the eastern Mediterranean as part of an Environmental Baseline Survey and Environmental Impact Assessment conducted for oil and gas interests. CSA GeoSpatial Services has plans to expand the analysis to benefit other countries in the region, and potentially in other parts of the world.”
