Time series of meridional DWBC transport partitioned by layer for the period May 10, 2004 to October 10, 2010. Negative values correspond to equatorward flow. The colors denote: Upper -yellow, and Classical Labrador Sea Water -green, Iceland-Scotland Overflow Water -purple, and Denmark Straight Overflow Water -black. After Toole et al. (2011), extended through the 2008-10 setting of the moored array. Delay in fully resetting the array due to bad weather in 2008 is responsible for the gap in the time series. Details about this transport time series are described in Toole et al. 2011.
