Imagery for Requested MPSR

The Satellite Analysis Branch (SAB) of NOAA/NESDIS detects oil slicks in satellite imagery over U.S. waters (and international waters when requested by OR&R) in order to meet the NOAA Office of Response & Restoration (OR&R) need for oil spill information. The Marine Pollution Surveillance Report (MPSR) are typically issued by SAB satellite analysts when accidental or intentional marine oil spills are detected in imagery, but in this case a MPSR was specifically requested by OR&R for an area of a known oil spill. The report consists of manual detection and mapping of oil slicks primarily through the use of available moderate to high resolution satellite imagery, which can range from public to private sources. Imagery typically includes one or some of the 7 following satellite sources: VIIRS, MODIS, Aster, Landsat, Sentinel, Radarsat-2, Worldview. Please see the links to these imagery sources in the URL section below, and the use constraints and licensing information in the child items section below.

The Marine Pollution Surveillance Report (MPSR) is a product package created in the NESDIS Satellite Analysis Branch (SAB) when a marine anomaly is identified in U.S. waters or approaches that's believed to be the result of an accidental or intentional oil discharge. This specific imagery was used to generate an event-driven, requested report, which includes a JPEG map and shapefile. These products are then used to provide surveillance support to oil spill responders working in U.S. waters.

We request that you credit the National Oceanic and Atmospheric Administration (NOAA) & National Environmental Satellite, Data and Information Service/Satellite Analysis Branch (NESDIS/SAB) when you use these data in a report, publication, or presentation.

Please credit NOAA/NESDIS if data is used in other products or other ways. Caveats such as the fact that the product is still experimental should also be included if the product is being redisplayed.

Imagery may include: Optical imagery from MODIS (NASA), VIIRS (NOAA), Sentinel-2 (ESA) and Landsat (USGS), ASTER (NASA), as well as SAR imagery from Sentinel-1 (ESA) and RADARSAT-2 (MDA) are routinely scanned for possible oil anomalies. The advantage of optical imagery is the ability to generate wavelength combinations that help distinguish oil from vegetation and other false positives. Disadvantages include being limited to daylight hours and cloud free weather conditions. SAR imagery allows for the detection of oil overnight and through clouds. Disadvantages associated with SAR include difficulty in positively identifying the substance as oil rather than vegetation or other false positives. Once a possible area of oil is identified, a wide array of ancillary data is consulted to help confirm the presence of oil.

Uncertainty in oil detection relies on environmental conditions and satellite imagery quality. Specific remarks on accuracy are included in each report.

N/A

The Marine Pollution Surveillance Report (MPSR) is created in near real time by an operational analyst when an anomaly believed to be oil is identified in satellite imagery. SAB analysts manually integrate data from numerous imagery sources including Synthetic Aperture Radar (SAR) and high resolution visible imagery along with various ancillary data sources. The result is a quality-controlled display of the locations of possible detected oil on the surface of the ocean.
