http://wapo.st/1N1hzaD And now this week brings news of another potential mega-scale perturbation. According to a new study just out in Nature Climate Change by Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research and a group of co-authors, we’re now seeing a slowdown of the great ocean circulation that, among other planetary roles, helps to partly drive the Gulf Stream off the U.S. east coast. The consequences could be dire – including significant extra sea level rise for coastal cities like New York and Boston. |

I remember reading a few years or more back, that since 1950 the Gulf Stream had slowed 30%. Then a claptrap article very recently saying it had increased in speed. Cold water influx from melting ice has slowed at least the Gulf Stream. I would think that after all the ice has melted, the currents will speed up. I don't think there will be anyone measuring it........ |

http://pubs.usgs.gov/tm/3a22/pdf/tm3a22_lowres.pdf It seems the Acoustic Doppler Current Profilers (ADCP) have issues if there are variations in salinity and or temperature in addition to the normal problems with the changes in the speed of sound at depth. I suppose that "very high accuracy" allows for a +7% variation as indicated is the range of accuracy for this type of sensor. |
