Note how the knock downs in December 1991 and February 1993 are related with reversals in the flow. The output was written at 6-hour intervals. At these times, the transports were blanked and interpolated using EPIC as described above. All transport series were filtered to remove oscillations less than one week and decimated to daily intervals. All spectra presented are variance preserving and were obtained from 2 year series in the deep moorings and 660 day series for the shallow water transports.
Negative values indicate southward transports.
The numbers within the graphs correspond to the period of the peaks underneath. The numbers within the graphs correspond to the period of the peaks underneath. Mean St. Dev. Mean St. Dev. There is a mean southward flow, with the most surface intensified profiles at moorings 4 and 5, while mooring 6 shows a more barotropic behavior.
