Satellites provide the following data on theoceans

Satellites provide the following data on the oceans: Sea surface temperature, sea level height, ocean currents, and ocean winds. It is also possible to monitor accidents, such as large oil spills, and periodic oscillations in the sea that affect global weather patterns, such as El Nino in the Pacific Ocean.

: Remote sensing involves collection of information about an object or phenomenon without direct contact with it. Sensors mounted on platforms such as aircraft, satellites, or drones enable the collection of data about Earth's surface, including land cover, vegetation, topography, and geological features.

: Satellite scans help to chart long-term glacier changes on a local, regional and global scale. Their ability to remotely monitor changing surface area, height, mass and the speed at which glaciers flow helps to estimate how these factors contribute to sea-level rise and the release of more freshwater.
