\n\t\t20 years of data demonstrates it remains stable<\/p>\n


\n\tNARRAGANSETT, R.I. \u2013 March 3, 2014 \u2013 Several recent studies have generated a great deal of publicity for their claims that the warming climate is slowing the pace of the Gulf Stream. They say that the Gulf Stream is decreasing in strength as a result of rising sea levels along the East Coast. However, none of the studies include any direct measurements of the current over an extended period to prove their point. <\/p>\n


\nBut this is exactly what has been underway at the 溏心vlog免费B站 and Stony Brook University for the last 20 years: measurement of the strength of the Gulf Stream. And according to a paper published in Geophysical Research Letters, the researchers find no evidence that the Gulf Stream is slowing down. These new results reinforce earlier findings about the stability of Gulf Stream transport based on observations from as far back as the 1930s. <\/p>\n


\n\tH. Thomas Rossby, a professor at the 溏心vlog免费B站 Graduate School of Oceanography, has spent much of his long career studying ocean circulation \u2013 especially the Gulf Stream \u2013 and how it makes its way across the Atlantic towards Europe and as far north as northern Norway. For the last 20 years he and his colleagues have measured the Gulf Stream using an acoustic Doppler current profiler (ADCP) attached to a ship, the freighter Oleander, which makes weekly trips across the Gulf Stream from New Jersey to Bermuda. The instrument, which measures the velocity of water moving beneath the ship down to more than 600 meters, has collected some 1,000 measurements of the Gulf Stream since it was installed in late 1992.<\/p>\n


\n\t\u201cThe ADCP measures currents at very high accuracy, and so through the repeat measurements we take year after year, we have a very powerful tool by which to monitor the strength of the current,\u201d said Rossby. \u201cThere are variations of the current over time that are natural — and yes, we need to understand these better — but we find absolutely no evidence that suggests that the Gulf Stream is slowing down.\u201d<\/p>\n


\n\tThe rapidly flowing Gulf Stream plays a major role in the global heat balance through its transport of very warm water from the Caribbean toward Europe. <\/p>\n


\nFor this reason alone, Rossby says, there is good reason to be concerned about the long-term stability of the Gulf Stream, since if the Gulf Stream were slowing, a decrease in the flow of warm water to the northern North Atlantic could cause significant cooling in parts of Europe. But the data tell him that there is no evidence that this is happening, contrary to recent claims in the literature. <\/p>\n


\n\tAlthough he officially retired in 2011, Rossby is continuing his Gulf Stream research and hopes to install a new instrument on the Oleander in the coming years that will be able to profile currents to even greater depths. <\/p>\n


\n\t\u201cOnce we do that, all of the water going north will be well within our reach,\u201d he said.<\/div>\n","protected":false},"excerpt":{"rendered":"
