We welcomed U.S. Research Vessel Knorr to Reykjavik this week. The Knorr, which is operated by the Woods Hole Oceanographic Institute, is known as the vessel that discovered the Titanic and hydrothermal vents at the bottom of the ocean. The Knorr has been visiting Iceland for many, many years to conduct oceanographic research in the area. One of its recent trips was used to study the recent discovery of a warm current around Iceland by two leading Icelandic oceanographers. The potential implications of the newly discovered current for climate change could be enormous.
