A NASA researcher finds that the amount of sea ice that moves between Greenland and Spitsbergen, a group of islands north of Norway, is dependent upon a "wave" of atmospheric pressure at sea level. By being able to estimate how much sea ice is exported through this region, called Fram Strait, scientists may develop further insights into how the ice impacts global climate.
This export of sea ice helps control the thermohaline circulation, a deep water ocean conveyor belt that moves warm, salty water poleward and cold, fresh water toward the equator. The thermohaline circulation is one of the primary mechanisms that maintains the global heat balance.
Don Cavalieri, a researcher at NASAs Goddard Space Flight Center in Greenbelt, Md., discovered a link between the transport of sea ice through this region and the position or phase of the longest sea level pressure wave circling the Earth at polar latitudes.

Combining an atomically thin graphene and a boron nitride layer at a slightly rotated angle changes their electrical properties. Physicists at the University of Basel have now shown for the first time the combination with a third layer can result in new material properties also in a three-layer sandwich of carbon and boron nitride. This significantly increases the number of potential synthetic materials, report the researchers in the scientific journal Nano Letters.
Last year, researchers in the US caused a big stir when they showed that rotating two stacked graphene layers by a “magical” angle of 1.1 degrees turns...
