Introduction Between January 1973 and May 1975, the National Science Foundation sponsored a cooperative field program of direct measurements of circulation on the continental shelf of the west coast of the Florida peninsula. With a variety of instruments, records of ocean currents, bottom pressure, coastal sea level and winds over the shelf were compiled, some of which are continuous for nearly two years. Nova University (Dr. Pearn P. Niiler) and University of Miami (Dr. Christopher N.K. Mooers) were responsible for the deployment and recovery of the current meters and the primary data compilation of the water velocity and temperature. Bottom pressure data and bottom temperatures were obtained by the University of Washington (Dr. Lawrence H. Larson) and sea-level data and bottom pressure were obtained by Nova University (Dr. Mark Wimbush). A continuous sea-level wind record was obtained at 26°N, 84°W by compilation of ships of opportunity wind logs, interpolation of coastal wind records and the six-hourly National Weather Service surface level atmospheric pressure charts. Mr. J. Fernandez-Partegas of the University of Miami did the compilation. There were six arrays of instruments deployed on the shelf (Table I). As listed below, the data sets from the first four are described in data reports issued by the University of Miami and Nova University. In this report, we present the overview of this moored array data and the summary of the moored current meter data for the fifth (May 1974-Nov. 1974) and the sixth array (Nov. 1974-May 1975). Published data reports on current meter, sea level, meterological data are: "Current meter data report from Fall 1973", NSF Continental Shelf Dynamics Program, by J.F. Price and C.N.K.

The current meter data which are reviewed in this report are from VACM's which were moored on rather standard, subsurface moorings. Plaisted, et. al., 1975, op.cit.,discuss the mooring configuration, sampling scheme and raw data processing. The description of the operation of the bottom pressure gauge deployed by Nova University is found in Wimbush (1977). The accuracy of the wind analysis is described by Niiler (1975). The mooring locations for the entire study are shown on Figure 1. This Figure should be viewed together with TablesI and II, which give the specific locations of the moorings and the depth of the instruments. The designation of the instruments and moorings changed a number of times throughout the observational period. Here we use the designations assigned by the original 2 Figure 1.

In the following publications, specific use is made of this data set to interpret the dynamics of the circulation.

Current Meter Intercomparis ons Three models of current meters were used in the West Florida Shelf study: the Vector Averaging Current Meter (VACM), the Aanderaa RCM-4, and the Geodyne (now EG&G) model 850. Several intercomparisons of these models have been recently summarized by Beardsley, Boicourt, Huff and Scott (1977). In these 10 tests, the VACM and the 850 have compared well when used on subsurface moorings over the continental shelf. However, the Aanderaa has shown some measurement problems in shelf regions, causing some of its measurements to differ substantially from those of the VACM and the 850. Although subsurface mooring techniques remove the effects of surface wave pumping, which are significant in all of these meters when used near the surface, the Aanderaa sampling scheme can still alias the high frequency energy. In both VACM and the 850, vane direction and rotor speed are split into vector components which are then averaged over a present sample interval and recorded. In the Aanderaa, rotor speed is averaged over the sample interval and recorded with an instantaneous measurement of direction. In the presence of a sluggish low frequency motion,the high frequency motions will govern the position of the direction vane, provided they are of sufficient scale. The VACM and 850 sample scheme will tend to average out these high frequency variations in direction, but the Aanderaa scheme will not. Therefore, whenever the Aanderaa instrument is used in a particular environment, it is useful to carry out a few intercomparisons with other instruments to determine if the Aanderaa sampling noise is significant. Two intercomparisons between the Aanderaa and VACM instruments were carried out during the West Florida Shelf experiment. The first was made at a depth of 130 m in 200 m of water at mooring A in Array 1 during the winter of 1973. This intercomparison revealed a high degree of similarity in the data collected with the VACM and Aanderaa instruments. A scatter diagram of the reconstruced speeds (speed = (u 2 + v 2 ) 1/2 ) is shown in Figure 2. The scatter is shown about a line indicating a perfect 1:1 correspondence 11 2 4 6 8 VACM SPEED WINTER 73 INTERCOMPARISON Figure 2. Scatter diagrams of Aanderaa speed (cm/sec) vs. VACM speed (cm/sec) for Array 1 intercomparison on mooring A (instruments A2 and A3). Upper figure: hourly values of U and V from low-pass series (cutoff at .5 cph) have been used to compute speed. A linear regression yields Aanderaa speed = 0. 98 * VACM speed -0.42 with a correlation coefficient of .94. Lower figure: hourly values of U and V from M2 band pass series (cutoffs at .065 and .100 cph) have been used to compute speed. Linear regression yields Aanderaa speed= 0.66 * VACM speed + 0.77 with a correlation coefficient of .64. 12 and is typical of what one finds for VACM-VACM intercomparisons (see Figures 1 and 2 in McCullough, 1975). When high frequency energy is contaminating the Aanderaa measurements, one typically finds that the Aanderaa over-estimates the low values of the reconstruced VACM speed. Since this behavior is not indicated in this intercomparison, we can conclude that the two instruments give a consistent estimate of the velocity in this environment. Figure 2 also presents a scatter diagram of the speeds after the velocity has been band pass filtered about the semi-diurnal tidal band (.08 cycles per hour + 4-1/2 cycles per month). The half power points of the filter are at approximately .065 and 0.1 cph. Again, we do not see the characteristics of poor Aanderaa performance. However, a low signal to noise ratio is evident in this band. This noise, whether real or instrumental, is random in the two instruments and is responsible for the low correlation. The second intercomparison between the VACM and Aanderaa instruments was made in Array 2 at a depth of 50 m in 150 m of water during the fall of 1973. The instruments were placed on mooring I in order to be near or in the seasonal thermocline. Data were collected for a four month period. Unfortunately, intermittent sticking of the VACM rotor throughout the recording period made it impossible to conduct a valid intercomparison. The VACM instruments used in this experiment were identical in design to those used in the MODE experiment. These instruments usually developed carbonate deposits on the rotor bearings, causing the rotors to stick after a few months in the water (Dexter, Milliman and Scmitz, 1975). For this study, rotor sticking was determined by visually examining the time series plots of rotor speed for unrealistic intervals of zero value. End times 13 were set at least 12 hours prior to the first detectable onset of rotor sticking. After tidal analysis was performed on the edited data, evidence of fouling was found to occur prior to the sticking of the rotor. Consequently, we suggest that only the first two months of any VACM time series be used for accurate velocity measurements. 3. Computation Method of Summary Statistics-Array 5 and 6. In Array 5 and Array 6 the raw VACM data contain the vector averaged current and temperature every 15 minutes. The raw wind estimation is made every 3 hours, the sea level is recorded once an hour and the bottom pressure gauge data is sampled at various high rates, and typically 15 min. averages are produced. A cosine filter is used throughout to produce low-pass time series. Below is the half-power point of the filter used in each operation: Decimated time series 1 hourly Cosine filter half-power point 0.5 cph 2 hourly 0.2 cph Daily 0.1 cph 14 The computed means, variances, maximum-minimum values, and histograms are computed from 1 hourly data. The 30-day average statistics spectra are computed for 2 hourly data and time series plots of currents, temperature and the progressive vector diagram are computed from daily average data. Start time for 30-day averages are: Day after Jan. 1, 1974 Array 5 98 0000 GMT Array 6 330 0000 GMT Wind stress estimate, tr'' , is computed from wind speed estimate, according to the formula, T= 1.5 x 10 -3 u. The c.g.s. system is used throughout. 4. Low-Frequency Circulation Long records are available from current meters which are 50m below the surface and 6-10m above the bottom. The low-frequency circulation can be most clearly seen on the progressive vector diagrams (Figure 3 ) and is inferred from the long time series of the temperature (Figures 24-27). First we note thatnearthe bottom the flow is along isobaths, while 50m below the surface it is generally eastward, toward shore. The mean component of wind, in contrast, is to the west, off-shore. Because the Loop Current is known to make excursions into this shelf, the circulation within the 15 APR I MAY N 0 75km STA 2901 142 M JAN 75 I DEC I NOV 23 MAR I 0?5km STA- 3301 54 M APR 1 MAY1 MAY I Figure 3. Progressive vector diagram for Array 6. 16 observational area is at times very strongly affected by it. The Loop Current has significant year to year variability, and in concert we notice no clear seasonal cycle across the entire shelf. The progressive vector diagrams, however, do suggest that particularly in winter of 1973-74 and 1974-75, the flow in the entire water column shallower than 110m is to the south, while the bottom flow at 150m isobath on the average flows to the north. Note that the mean flow at 150m ( #15 ) in May-Nov. '74 is to the south. In the period of Nov. '74-April '75, the 50m mean flow was to the left of the mean wind. The seasonal cycle is more evident in the temperature records. In summer, warming of the entire column occurs above 100m, which is followed by winter time cooling. The winter mixed layer in this area is typically 100m deep. Below the direct effect of the seasonal heating a very different cycle occurs, for the bottom water at 150m is colder in summer than in winter. Furthermore, while this cooling in '74 and '75, in spring is quite rapid, the warming occurs much more slowly throughout the year. Evidently, cold water flows unto the mid-shelf, or "upwells", quite rapidly in spring, perhaps in response of the intrusion of the Loop Current into the Northeastern Gulf of Mexico. The mean bottom temperatures at 150m depth, are very nearly equal within each array, indicating that in 7-6 month mean the isotherms align with isobaths. The daily current stick diagrams for Array 5 and 6 are displayed on Figures 28-32. The inertial motions and tidal motions have been effectively filtered from these. Here it is evident that the low-frequency kinetic energy at the bottom is quite uniform from shelf depths of 200m-60m (also see Plaisted et al., 1975), however, the flow at 50m below the surface is much more energetic over the deeper shelf. Energetically, large 17 fluctuations are found on the near surface instrument on #17, #31, #32, G, H, I and J. As with the mean motions, the low-frequency current ellipses are oriented along isobaths at the bottom and these ellipses rotate counterclockwise toward the surface. Low-frequency temperature variability is more intense at the bottom, especially when the shelf is rendered vertically (and horizontally?) homogeneous to 100m in winter. We have studied the coherence of the low-frequency motions in the period Aug. '73-May '74 (Arrays 3, 4) and Nov. '74-May '75 (Array 6). Very clear and significant propagation of low frequency current variability was found to the north in Array's 3 and 4, while in Array 6 propagation and horizontal coherence is not as clearly evident. Mesoscale winds have more energy in the clockwise rotary sense. The most coherent variations with local winds are found in winter and in shallow water in moorings K and #34. In summertime, no apparent relationship exists between the local winds and the currents in this area. 5. Tidal Currents The coastal sea-level and bottom pressure measurements reveal strong, and significant tidal lines at K 1 , 0 1 , M2 and 52. frequencies. Spectra of the currents on the shelf indicate that here both diurnal and semi- diurnal, tidal currents rotate clockwise. The diurnal band in this latitude is very close to the inertial frequency band. In the 50m level instruments, there is a relative continuum of energy across this diurnal band. In fact, the kinetic energy spectra at 50m are all elevated with respect to the bottom instruments in the entire band from 10 day period to inertial period, such that the diurnal and inertial motions in the 18 surface layers are not as dramatically more energetic as they are next to the bottom. As from the stick diagrams, there is a definite impression from the spectra that the sub-inertial frequency motions are strongly attenuated near the bottom, while the supra-inertial or tidal motions are not. The supra-inertial wave band is also more evident in the temperature signal near the bottom because, relative to the 50m instruments, near the bottom there is a dearth of energy between 20 and 1 day periods. No concise study of the internal waves with this data set has been attempted, however, tidal motions and energetics, are thoroughly analyzed by Koblinsky (Ph.D. Thesis, Oregon State University, 1979). The semi-diurnal tidal currents are horizontally and vertically coherent across the entire array. Figures 4 and 6 display the semi-diurnal ellipses. The strength of the tidal flow increases toward shore (recall that the low-frequency motions decrease toward shore) and the observed motions are consistent with the dynamics of a topographic, rotational gravity wave which propagates to the north-east. Figure 5 shows the energy flux associated with this semi-diurnal wave. The energy in the diurnal band, which also includes the inertial motions, is not coherent across any vertical or horizontal distance of the array and no simple consistent picture of motions has yet been achieved. Figure 7 displays the time series of current ellipses in the diurnal band. These ar non-stationary in size, direction and vertical structure from month to month. 19 DASHED LINE ELLIPSES USED FOR INSTRUMENTS IN MIDW ATER: GI, HI, 12. KI, Rt.
