Labrador Sea Water (LSW) property variations are analyzed using data from four hydrographic sections occupied along 20°W, from Iceland south toward the equator in 1988, 1993, 1998, and 2003. LSW between the Azores‐Biscay Rise and the Rockall Plateau steadily becomes deeper, colder, fresher, denser, and thicker over the 15‐year time series. LSW apparent oxygen utilization (AOU) remains unchanged during this time period. The changes analyzed are consistent with previously published spreading rates of 8 years for LSW from the Labrador Sea to 20°W, and emphasize the long reach of decadal LSW variability.
