This document lays out a framework by which defensible performance metrics for oil spill response can be developed in an analytic-deliberative process that includes a broad range of stakeholders and is informed by high quality scientific knowledge. Performance metrics can be used to: improve oil spill response planning, promote institutional learning post-response, support public communication ...
ABSTRACT Oil spill trajectory and fate modeling was used in inland response Full Scale Exercises including the Enbridge Des Plains River (fall 2018) Wisconsin 2019). The Spill Impact Model Application Package (SIMAP) to predict three-dimensional movement (i.e. trajectory) behavior fate) of a hypothetical release oil using site-specific environmental geographic conditions (including seasonal hyd...
Long-term monitoring of endangered species abundance based on acoustic recordings has not yet been pursued. This paper reports the first attempt to use multi-year passive acoustic data to study the impact of the Deepwater Horizon oil spill on the population of endangered sperm whales. Prior to the spill the Littoral Acoustic Demonstration Center (LADC) collected acoustic recordings near the spi...
Many satellite-borne image data have been acquired in the Arabian Gulf since the mid 80’s by different space agencies and have demonstrated oil spill related features at sea. Severe oil spills were caused occasionally by accidental or deliberate oil sludge dumping from passing ships. Serious damage to fishery, water desalination plants and natural habitats are concerned. The work done is the fi...
The Deepwater Horizon oil spill produced large subsurface plumes of dispersed oil and gas in the Gulf of Mexico that stimulated growth of psychrophilic, hydrocarbon degrading bacteria. We tracked succession of plume bacteria before, during and after the 83-day spill to determine the microbial response and biodegradation potential throughout the incident. Dominant bacteria shifted substantially ...
Time-series data collected over a four-year period were used to characterize patterns of abundance for pelagic fishes in the northern Gulf of Mexico (GoM) before (2007-2009) and after (2010) the Deepwater Horizon oil spill. Four numerically dominant pelagic species (blackfin tuna, blue marlin, dolphinfish, and sailfish) were included in our assessment, and larval density of each species was low...
We have applied the SIPE system (a classical planning tool, see [1] ) to the Coast Guard’s problem of oil spill response. The Coast Guard has final responsibility for cleanup actions when an oil spill occurs in coastal waters. Oil spill actions fall into two types, "deploying" clean up equipment from the site near the coast where it is stored, and once deployment is complete, "employing" the eq...
In this paper, we present a comparison between several algorithms for oil spill classifications using fully and compact polarimetric SAR images. Oil spill is considered as one of the most significant sources of marine pollution. As a major difficulty of SAR-based oil spill detection algorithms is the classification between mineral and biogenic oil, we focus on quantitatively analyzing and compa...
With the frequent occurrence of marine oil spill and the serious environmental pollution as well as enormous economic losses it causes, there is a growing demand for oil spill emergency response. It becomes a trend to research on spatial information analysis and publishing based on GIS. Compared with the expensive and system-huge commercial software, open source platform which is free and small...
