At each station, the weighted mean anomaly was calculated referred to the depth at which sigraa-t was equal to as read from STD curves. The direction and volume of transport Is shown in figure 9» Total volume transport as calculated is h$ x 10^ m3/sec through the area, with an error of 2j$ between incoming and outgoing transport. The presence of Internal tides (inferred by figure lU and discussed under VI. Tidal Influence) may account for the Fig. 9. Dirocti of transport calculated to an averago depth of 920 meters -- USS PURSUIT data For the most part, the GEK's are in good agreement with the cal- culated transport directions. Where the strong currents in disagree- ment are found, 2 sets, GEK's 25-26 and 27"28, may be explained by winds of 10 to 3J4 knots (high for the time of year) occurring 18 to 20 hours earlier. For GEK's 37-38 no simple explanation presents itself, but other observations taken the same day in the sane general area support the calculated transport direction,, Too much importance should not be attached to the discrepancies, however, since it was in this area that the time lag between GEK's and oceanographic sta- tions was Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Keen, D.
