Full text: The subsurface eastern boundary current of the North Atlantic between 32·N and 53·N (BSH-Bericht, Nr. 23)

I. Introduction 
This data report presents current data collected by the Bundesamt Шг Secschiffahrt und 
Hydrographic (BSH, Federal Maritime and Hydrogaphic Agency) between 1983 and 1995 
along the European and Northwest African continental slope between 32°N and 53°N, 
The mooring positions are located along the coast of the Iberian Peninsula, the northern 
part of the Moroccan coast (М3. R), in the Great and Little Sole Bank area (G-moori ngs), and 
west of the Irish Coast close to the Porcupine Bank (F-moorings). 
Itic deployment periods vary between 15 and 414 days. All current metres were 
Aanderaa RCM 4,5,7, or 8. The sampling interval for the long-term moorings was 60 minutes, 
for the shorter deployment peri odes (< 6 months) the sampling interval varies between 5 and 30 
minutes. 
Some of the data have been discussed in previous reports 1 ' 2 , but this report includes all 
BSH current data relevant to the subsurface Eastern Boundary Current north of 32°N. Table I 
and the map in Figure 1 give the mooring positions together with deployment time, water depth, 
and the number of current meter records in the respective mooring. 
For each mooring there is a table with mooring data followed by a table with low-passed 
current statistics and a progessive vector diagram (hereafter PVD) of all current meters in the 
mooring. For each record there is a lime series plot (low-passed), an energy density spectra for 
the zonal and meridional current component, and an individual PVD, For the current statistics 
and the time series a Gaussian low-pass over 48 hours was applied to remove short-term 
fluctuations such as tidal and inertial movements. 
The PVDs were processed from unfihercd data. The start position of the PVDs is 
marked by a big cross (+), The spacing of the Lime marks (x) depends upon the record length 
and is given in the text of the diagram. 
The spectra arc В lackman-Tukcy power spectra calculated with the Singular-Spectrum- 
Analysis Toolkit^.
