Remote Sensing of Oil Films in the Context of Global Changes

摘要: Since the middle of 20th century, during global industrialization, crude oil has become a major source energy, and problem spills in sea public concern. Spilled interacts with marine environments, causing damage to ecosystems influencing ocean-atmosphere interaction. The impact accidental is catastrophic for coastal zones, far-reaching consequences, not realized or anticipated previously. Sea surface films play significant role important climate processes such as exchange momentum, heat gas between ocean atmosphere. However, nowadays there no estimating method determining how fully frequently covered by films, even when slicks are imaged from space. Remote sensing believed offer an effective mean accounting which could lead improvement representing air-sea interactions models. Among remote techniques, spaceborne Synthetic Aperture Radar (SAR) primary sensor used spill surveillance. Oil floating on detectable SARs, because they damp short waves that responsible radar backscattering. European Asian seas have been chosen test basins work out mapping technology using SAR images, these studies demonstrated high potential SAR-equipped satellites. An approach also developed. It based conducted within analysis framework geographic information system (GIS). GIS-made maps can be valuable about distribution, statistics sources. They allow scientists identify most polluted waters – step development monitoring scenario. Finally, basis determination volumes extent satellite provided. This paper reviews discusses this context changes.
