1. 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:

Dynamics Program, by J.F. Price and C.N.K. Mooers, R.S.M.A.S.,
University of Miami, #UM-RSMAS, #74035, Dec. 1974.

Hydrographic data taken on the deployment and recovery operation are
reviewed in:

Each of the above data reports present the method of measurements,
calibration and accuracy of instruments. 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. 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

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

Linear regression yields Aanderaa speed= 0.66 * VACM
speed + 0.77 with a correlation coefficient of .64.

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:

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.

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

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.

7. Acknowledgments
It is a pleasure to acknowledge the support of the National Science
Foundation and Oregon State University for the support through data
preparation phases of and analysis for Arrays 5 and 6. Mr. Phil Bedard
headed the capable field crew in the field experimental phases and Mr.
Keith Waters was instrumental in initial phases of data analysis. This
work could not have been completed without the generous help of
Professor C.N.K. Mooers, Dr. J.F. Price and Professor G. Weatherley. We
are grateful for the support of the Atlantic Marine and Oceanographic
and Meteorological Laboratory of NOAA for support in preparation of this
Summary Report under contract NA-79-RA-C-00048, through Interagency
Agreement EX-76-A-29-1041, Task Order TO27 with the Department of Energy.
