This paper presents a technique to detect oil spills in ENVISAT Advanced Synthetic Aperture Radar (ASAR) images using radar backscatter thresholding and logistic regression analysis. We developed and tested this technique using 4 Envisat ASAR images that were acquired many days after the M/T Solar I oil spill incident occurred on August 11, 2006 in Panay Gulf, southwest of Guimaras Island in Vi...

Knowledge of the spatial distribution of oil thickness patterns within an on-water spill is of obvious importance for immediate spill response activities as well as for subsequent evaluation of the spill impacts. For long-lasting continuous spills like the 2010 3-month Deepwater Horizon (DWH) event in the Gulf of Mexico, it is also important to identify changes in the dominant oil features thro...

An increasing awareness of environmental issues, coupled with a number of recent events, has focused considerable attention on the likely consequences of a large oil spill. If the impact of these accidental releases is to be minimises, the risk assessment and contingency planning must be based upon a sound understanding of the dispersion process. This is required to determine both the lateral s...

Detailed airborne, surface, and subsurface chemical measurements, primarily obtained in May and June 2010, are used to quantify initial hydrocarbon compositions along different transport pathways (i.e., in deep subsurface plumes, in the initial surface slick, and in the atmosphere) during the Deepwater Horizon oil spill. Atmospheric measurements are consistent with a limited area of surfacing o...

The nation’s largest maritime oil spill occurred on the west coast of the Korean Peninsula on December 7, 2007. All civilian space-borne SAR sensors including TerraSAR-X, ENVISAT ASAR, RADARSAT-1, ERS-2 SAR, and ALOS PALSAR acquired imageries over the contaminated area. Dark patches observed in these SAR images revealed the presence of oil spills, and showed how wide the spilled area is and how...

We present a framework for automatic detection of oil spills in SAR images. Multi incident angle and multi polarization SAR data are ingested into the framework in order to optimize revisit times and thereby the temporal and spatial coverage. Dark spots in the images are primarily detected by adaptive thresholding. For each of them a number of features are computed in order to classify the slic...

Monitoring and M A Record-Breakin Geophysical Mon Copyright 2011 b 10.1029/2011GM On 22–23 June 2010, the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) L band radar imaged the Deepwater Horizon oil spill and the effects of oil that was transported within the Gulf of Mexico. We describe the campaign and discuss the unique contributions of the UAVSAR radar to the study of the detec...

In view of the fact that oil spill remote sensing could only generate the oil slick information at a specific time and that traditional oil spill simulation models were not designed to deal with dynamic conditions, a dynamic data-driven application system (DDDAS) was introduced. The DDDAS entails both the ability to incorporate additional data into an executing application and, in reverse, the ...
