ESA’s Swarm mission thoroughly probing mysterious ocean’s magnetic field, which has long been one of the most controversial theory, as the mission is continually providing scientists with more exciting evidences clearing the arguable theories of earth’s origin of the protective shield, its behavior and changes.
Swarm mission was launched by European Space Agency (ESA) dedicating it to explore the Earth’s magnetic field and obtain more précised and high-resolution data belonging to the direction, variations and strength of the robust magnetic field of the Earth, along with more accurate navigation, electric field measurements and accelerometer.
“We have used Swarm to measure the magnetic signals of tides from the ocean surface to the seabed, which gives us a truly global picture of how the ocean flows at all depths – and this is new”, said Nils Olsen from Technical University of Denmark. “Since oceans absorb heat from the air, tracking how this heat is being distributed and stored, particularly at depth, is important for understanding our changing climate.”
Now, Swarm mission is heading towards its next aim to track the variations across the magnetic field yielded in the oceans on the Earth, more deeply than ever done. However, the scientists say these new findings obtained by the Swarm satellites will be exciting the upcoming European Geosciences Union meeting 2018 in Vienna, Austria.
“This is the highest resolution model of the lithospheric magnetic field ever produced”, Erwan Thebault of the University of Nantes stated. “With a scale of 250 km, we can see structures in the crust like never before. And, we have gained even finer detail in some parts of the crust, such as beneath Australia, where measurements from aircraft have mapped at a resolution of 50 km.”
