Oceanography 98 Lavelle et al.: Results of Meter and Sediment Observations shelf (Swift et al., 1973). Field work was divi- ded into two concurrent operations: a sediment tracer experiment and a current meter array of high spatial resolution. We present here a quali- tative, preliminary view of the data collected in those efforts. Current Meter Observations During the first six weeks of the current meter operation (October 16 to December 4, 1974), nine- teen stations (Figure 1) were occupied. A single current meter string was retained in the area during the remainder of the experiment. Aandaraa RCM-4 Savonius rotor current meters which record instantaneous direction and integrated average speed at 10-minute intervals were used throughout. Measurement emphasis was placed on a well-defined ridge and trough; meters were located on a crest, flank, and trough on each of three transects (B, C, and D of Figure 1) as well as the adjacent flank of transect C. Additional meters were set outside the central study area to measure far- field velocities. Flow during the observation period trended both east and west, parallel to the coast. Figure 2 is a vector time series of velocities at station 2C ( m above the bottom) and is representative of near-bottom water movement during one of the most active periods of flow. The data presented here have been subjected to a 40-hr low pass filter and then resampled at hourly intervals. Although east is the dominant flow direction during this sampling interval, the most intense flow was westward during a three day period near the end of this period. Predominance of eastward flow is consistent with 15 - 16- ,*os*- 17 T ia ( 19 m 20 f 21 L 22 Wr 23 i 24 V 25 r 26 1 27 k 28 f 29 j 30 !.! DEC 74 " 2 <^k\ 3 ™d».
