Space imagery detects petroleum in Kerch Strait
14 August 2008, 4:01pm
The situational map of the Kerch Strait produced through processing of RADARSAT-1 image of 6.8.2008. The map shows the area or the sunken forward part of the Volgoneft-139 tanker (yellow dot), pollution with petroleum product leaking from the sunken section or the tanker (in maroon) and film contamination likely with petroleum product (in red).
Space imagery processed by ScanEx in Russia has once again detected the presence of petroleum product in the Kerch Strait.
The scheduled periodic scanning of the Kerch Strait detected new evidence of the Kerch Strait area pollution with petroleum product leaking from the sunken forward part of the Volgoneft-139 tanker.
As a result of processing the RADARSAT-1 radar image received by SCANEX RDC Moscow Center on August 6, 2008 the specialist discovered a threadlike tail of oil pollution around 21 km long and 3.66 square km in area.
The front end of the slick starts directly from the point of likely whereabouts of the forward section of the sunken Volgoneft-139 tanker with respect to coordinates of N45'12.75 and E36' 31.89. Due to daily wind and current direction changes, the tail has a complex curved shape and impulse towards the Taman Peninsula.
The image clearly detects the other two slicks of pollution, with the total area of around 2.1 sq. km., which presumably formed due to oil leaks from the Volgoneft-139 tanker, but separated from the primary tail about 1-2 days ago.
Insignificant film contamination, possibly caused by petroleum product, is also noticeable along the Taman Peninsula coast. Hydrometeorological conditions as of the time of imagery on August 6, including west wind with velocity of 3-5 m/sec, contributed to detection of the pollution.
ScanEx Center will continue regular monitoring of the Black and Caspian seas area condition accompanied with real-time reception and processing of RADARSAT-1 and ENVISAT-1 data.
