The European Space Agency and Eumetsat have just released the first data from their new satellite platform, Sentinel 3-A. This groundbreaking new Earth observation platform can monitor a wide range of Earth systems, and will play a vital role in understanding our planet into the future.

Using GIS in Government Guides

Landsat 9 Will Launch in 2020

The Landsat series of satellites has been imaging the Earth’s surface for nearly 50 years, providing vital imagery for a range of purposes from the natural sciences to civil administration and conflict monitoring. NASA and the USGS recently announced that the next iteration of the program, Landsat 9, is due to launch in 2020.

Scientists at Plymouth Marine Laboratory (PML) in the UK, funded via the UK National Centre for Earth Observation, working with colleagues from France, have combined ocean-colour satellite data made available through ESA’s Climate Change Initiative with in situ measurements from Argo and new Bio-Argo floats, partially-funded by the UK Natural Environment Research Council, to work out how much energy is transported from the ocean’s surface down to the mesopelagic layer. They estimate that seasonal mixed layer pump moves around 300 million tonnes of carbon each year, which is a vital energy source for organisms living in the deep dark part of the ocean.
