Contribution of satellite remote sensing acquired in the visible, near infrared and thermal infrared to the study of Eurasiatic Arctic seas
The overall objective of our work was to improve the knowledge of the Arctic marine environment. Using satellite remote sensing operating in the visible, near infrared and thermal infrared, we studied oceanic surface structures over the Barents and Kara seas, as weil as in the southern part of the B...
