Abstract
Reducing
the risk of oil spill disasters is essential for protecting the
environment and reducing economic losses. Oil spill surveillance
constitutes an important component of oil spill disaster management.
Advances in remote sensing technologies can help to identify parties
potentially responsible for pollution and to identify minor spills
before they cause widespread damage. Due to the large number of sensors
currently available for oil spill surveillance, there is a need for a
comprehensive overview and comparison of existing sensors. Specifically,
this paper examines the characteristics and applications of different
sensors. A better understanding of the strengths and weaknesses of oil
spill surveillance sensors will improve the operational use of these
sensors for oil spill response and contingency planning. Laser
fluorosensors were found to be the best available sensor for oil spill
detection since they not only detect and classify oil on all surfaces
but also operate in either the day or night. For example, the Scanning
Laser Environmental Airborne Fluorosensor (SLEAF) sensor was identified
to be a valuable tool for oil spill surveillance. However, no single
sensor was able to provide all information required for oil spill
contingency planning. Hence, combinations of sensors are currently used
for oil spill surveillance. Specifically, satellite sensors are used for
preliminary oil spill assessment while airborne sensors are used for
detailed oil spill analysis. While satellite remote sensing is not
suitable for tactical oil spill planning it can provide a synoptic
coverage of the affected area.
