Polar-orbiting satellite observations are of fundamental importance to explore the main scientific challenges in the Arctic Ocean, as they provide information on bio-geo-physical variables with a denser spatial and temporal coverage than in-situ inst

Satellite optical and infrared images can be degraded by a piecewise-constant random artifact called random telegraph signal (RTS), which is caused by unstable semiconductor defects in the photodetector. In this letter, we aim at proposing new techni

A global seabed sediment map has been developed since 1995 to provide a necessary tool for different needs. This project is not completely original since it had already been done in 1912 when the French hydrographic Office and the University of Nancy

Since the 70’s, ship-mounted three-component magnetometers are used for marine geophysical mapping, with the benefits of being able to be operated permanently with a minimum of technical maintenance. However, to obtain accuracies similar to those o

Instruments used to measure speed and direction of sea currents are equipped with magnetic compass and tilt sensors, in order to be able to reference their data in a terrestrial referential. Compass being sensible to their magnetic environment, it is

Current profilers and current meters have a magnetic compass and tilt sensors for relating measurements to a terrestrial reference frame. As compasses are sensitive to their magnetic environment, they must be calibrated in the configuration in which
