A Jet Stream in the Middle of the Earth

Elizabeth Borneman

Researchers from the University of Leeds published an article in the journal Nature GeoScience with data gathered by the Swarm satellites that reveals the existence of a molten core jet stream using changes in the magnetic field.

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.

This global land-cover map was created using data from the Envisat mission for the 2010 epoch (2008–12). This is the most recent data product from the Climate Change Initiative (CCI) Land Cover team led by the Université catholique de Louvain, showing 22 different types of global land cover classes, plus 14 regional land cover classes.
