Major Oil Spill in the Mediterranean

French and Italian maritime authorities have commenced cleaning a major spill that has spread 20 kilometers in the Mediterranean Sea after two cargo ships collided north of the island of Corsica on Monday 8 October 2018.

European Space Imaging captured a series of satellite images of the site on Tuesday 9 October at 50 cm resolution with WorldView-2.

The vessels involved in the accident are the Ro-Ro Ulysse, owned and operated by the Tunisian shipping company Cotunav, which ran into the boxship CSL Virginia, owned by Cyprus Sea Lines while it was anchored about 30 km off the northern tip of the island causing upwards of 600 tonnes of fuel to be leaked.

Whilst no one was injured during the collision, the extent of the damage is considerable. Although it is still too early to determine exactly what happened, satellite imagery analysed from before and after the incident can provide key insights to assist the investigation process.

“Satellite Imagery is useful for first responders of any crisis to assess the scope of damage and get another view of the scene. It can also help to monitor and detect any changes that may be critical to minimising or even eliminating further catastrophe” said Adrian Zevenbergen, Managing Director of European Space Imaging. “The benefit of satellite imagery is that the different spectral bands can be used to classify unidentified materials making it an invaluable source of information for maritime disaster management.”

In an effort to contain the disaster, tugboats have been dispatched from three Italian ports and the French navy has also provided a vessel specialised in containing and cleaning up spills with oil spill experts dragging a floating barrier to contain the oil followed by the use of a skimmer to suck up the fuel.

“Satellite remote sensing plays a very strategic role in maritime surveillance and supports the entire response process, from providing initial detection and assessment for situational awareness to directing clean-up efforts” said Dr. Melanie Rankl. “Very high resolution satellite imagery is an additional asset to that of traditionally used radar-based oil spill detection technology. Its ability to provide a detailed overview of the area plays a complimentary role in conducting on-going assessments and monitoring the extent of damage.”

Satellite Imagery for Emergency Management

The use of satellite imagery for emergency response and management is invaluable. Both optical and SAR images help rescuers save lives when disasters happen, assist with damage assessments, and in many cases contribute to successfully preventing and predicting emergencies. Which events can be prevented? How exactly do first responders use satellite images? When are they better than other methods? We have summarised our 20+ years of experience in this article.

Satellite Imagery as a Valuable Tool for the New Common Agricultural Policy 2023–2027 

On 1 January 2023, the new Common Agricultural Policy for years 2023–2027 entered into force. Hand in hand with the provided subsidies goes the necessity for monitoring and controls, which falls to the individual Member States. Therefore, an efficient, reliable, and cost-effective source of data is needed. Such source is Very High Resolution (VHR) satellite imagery. It allows you to conduct in-depth analysis of plant and soil conditions, map land use at wide scales with incredible detail and accuracy, and ensure that agricultural goals are being met.
