Extensive near real time use was made of ERS-1 SAR images for pollution monitoring in Norwegian waters throughout 1993. This paper presents four rather different events which demonstrate the slick detection capability of ERS-1 under favourable wind conditions. The detected pollutants were: 1) A mixture of fish oil and diesel, 2) Run-off water from an open depository, 3) A controlled chemical spill, and 4) Drilling fluid from an oil rig. In all four cases direct action was taken to clarify the nature of the ERS-I slick observations. However, no clean-up operations were required.
Extensive ERS-1 SAR coverage of the Vestfjorden area has provided many cases where ocean features such as current shears, internal waves, and wind fronts can easily be seen in the SAR images. Some examples of ERS-1 imaging of the Moskenes tidal current are also presented in this paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
