Mapping the Vector Correlation Between Velocity Time Series in the Upper Ocean and the Deep Water of the North Atlantic
Abstract
To measure the attenuation of surface effects with depth, this study surveyed historical time series of velocity obtained on current meter moorings by POLYMODE, WOCE and other experiments in the North Atlantic. Vector correlations were obtained between time series obtained in the upper ocean and those obtained at 4000 m and below on single moorings. The vector correlation uncovered a very strong relationship between the upper ocean and near-abyssal circulation: the correlation between time series in the upper 1000 m and those at 4000 m and below is as high as 0.8 on some moorings. The highest correlation estimates appear to be found away from the strong current systems, and in particular, away from their boundaries.
