End of the Rainbow, Ends of the Earth

In August 2011, R/V Knorr sailed to the North Atlantic to deploy a set of moorings across the Denmark Strait. The moorings will remain in place for one year as part of a study led by WHOI physical oceanographer Robert Pickart to measure water flowing through the strait deep beneath the surface. A recently discovered flow known as the North Icelandic Jet is believed to be an important part of circulation patterns in the North Atlantic that helps regulate regional climate patterns in North America and Europe. The team will return in August 2012 to retrieve the moorings and conduct additional surveys across the strait. (Photo by Dan Torres, Woods Hole Oceanographic Institution)
