I am looking to obtain free satellite images to detect oil spills in the Mediterranean sea. What sensors would be most appropriate for this task and where can I download this type of data?
I would recommend Landsat or MODIS for this task. You can access Landsat or MODIS data through Earth Explorer or Reverb|Echo. There are a number of publications on the subject to help you along the way:
- Brekke, C., & Solberg, A. H. (2005). Oil spill detection by satellite remote sensing. Remote sensing of environment, 95(1), 1-13.
- Hu, C., Li, X., Pichel, W. G., & Muller‐Karger, F. E. (2009). Detection of natural oil slicks in the NW Gulf of Mexico using MODIS imagery. Geophysical Research Letters, 36(1).
