Satellite images are a powerful tool for Earth observation and monitoring sensitive areas. As part of the Copernicus program and mandated by the European Commission, ESA (European Space Agency) has implemented the Sentinel satellites, the guards of the planet. Thanks to this program, we could detect hydrocarbon pollution at large of the Brazilian coasts and provide evidence for local authorities to help uncover the origin of this major disaster.
At MURMURATION, we confirm the catastrophic situation that these Brazilian coasts are currently experiencing. As shown in the following Sentinel images, we are able to detect oil pollution off the Brazilian coasts in the east, in the state of Bahia.
An oil slick visible on a Sentinel-1 radar image
Oil slicks are observed spanning over 20km, which corresponds to 800 Tennis courts!
The Sentinel 1 radar images of the Copernicus program provide all-weather imagery (passing through cloud cover) thus enabling the handling of emergency situations (natural or industrial disasters) and environmental monitoring (sea ice, glaciers, water extents, landslide, and so on).
An oil slick visible on a Sentinel 3 optical image
An extent of about 10 km of oil slicks was observed off Açu de Torre … which corresponds to nearly 400 tennis courts!
Sentinel 3 OLCI satellite images (Ocean and Land Color Instrument) allow measuring the state of the oceans and coastal zones (pollution, current …) thanks to color levels (spectral bands).
The Brazilian oil spill is an unprecedented ecological disaster with a short, medium and long-term impacts on the natural ecosystems and the economy of the country. Marine ecosystems are becoming stagnant while the country’s economy can be affected. Brazilian beaches, reputed for their beauty and attracting tourists from all over the world, may be deserted by travelers. The tourism sector is already heavily impacted by the situation ! But the worst is yet to come : Cleaning is almost impossible under current conditions.
O óleo no Nordeste e a destruição da Amazônia mostram as consequências do desmonte ambiental promovido pelo governo, prejudicando a imagem do país. Os impactos são gravíssimos para os oceanos, a Amazônia e a vida das pessoas. https://t.co/1PR9Rh6a1B #InimigoDoMeioAmbiente pic.twitter.com/sfZd2MxEla— Greenpeace Brasil (@GreenpeaceBR) October 23, 2019
