Distribution of Oil spill off-shore Lebanon using Remote Sensing. Oil and chemical spill in the marine environment have a widespread disaster. Real-time oil spill detection and monitoring using high special and spectral resolution severely remote sensing images to predict spill oil location. Build an oil spill distribution map by using GIS. Coastal states use both aerial and satellite remote sensing, this technique is also the dominant method of detection of oil slicks worldwide.

Jiyeh Oil Spill Disaster
●
Jiyeh Power Station Lebanese coast eastern Mediterranean
●
On July 13th 2006, Huge amount of oil spill (10 million gallon –
15000 tonnes) after bombed by Israel Air Force
●
10 km wide slick oil covered 170 km coastline
●
Threatened Turkey and Cyprus
●
The slick killed fish, threatened the habitat of endangered
green sea turtles, and potentially increased the risk of cancer
●
Impacted Mediterranean sea as a whole which is the most
important ecosystems in the world
●
Israeli jets deterred firemen from putting out the fire at the
storage units, which continued for 10 days, and the Israeli Navy
blockade stopped Lebanese and foreign officials from
surveying the damage of the spill.

The oil-spillage caused by the Jiyeh bombings in mid July,
had by 29 July coated the whole water surface in Byblos
harbor, some 60 km north of Jiyeh.

Advanced Space-borne Thermal
Emission and Reflection Radiometer●
ASTER satellite sensor is one of the five state-of-the-art instrument sensor systems on-board
Terra a satellite launched on December 18, 1999 at Vandenberg Air Force Base, California,
USA.
●
ASTER is a 15 meter, 14 band multi-spectral resolution instrument with short retrieval time. It
can be used for change detection, calibration, validation, and land surface studies.
●
ASTER satellite image data is expected to contribute to a wide array of global change-related
application areas, including vegetation and ecosystem dynamics, hazard monitoring, geology
and soils, land surface climatology, hydrology, land cover change, and the generation of digital
elevation models (DEMs).
●
ASTER high-resolution satellite capable of producing stereo imagery for creating detailed
digital terrain models (DTMs).

VNIR (Visible Near Infrared), a
backward looking telescope which
is only used to acquire a stereo

Conclusions
●
Remote sensing provide Real – time oil spill detection and monitoring
using high special and spectral resolution such as
– (1) flexible overviews of survey areas with regard to marine pollution and sea
traffic
– (2) quick assessments of oil spill sites
– (3) deterrence of potential polluters
●
GIS can qualitatively and quantitatively characterize the spatial and
temporal distribution of oil spills at sea and analyze the environmental
conditions of the area
