Abstract

- The Long-Term Upper Ocean Study (LOTUS) was a two-year field experiment

near 34*N, 70*W, designed to acquire a continuous set of measurements of

currents and temperatures in the upper, open ocean together with local

hydrography, meteorology, and mesoscale oceanographic features. The first

scientific moorings were deployed in May 1982. The first year of mooring

data, from May 1982-April 1983, is presented by Tarbell, Pennington and

Briscoe (1984, W.H.O.I. Tech. Rept. 84-36). The second year of mooring data,

from April 1983-May 1984, wheql the final mooring recovery occurred, is

INTRODUCTION -.

The Long Term Upper Ocean Study (LOTUS) began in 1979 when it became

clear that even massive one to two month upper-ocean experiments (e.g., JASIN)

could not provide the large variety of possible environmental conditions, nor

could they provide any insights into seasonal effects or give long-term statis-

tical response models.

The LOTUS experimental area (Figure 1) was at 340N, 70°W (the old Woods

Hole site L). The mooring array used in LOTUS was designed to sample the sur-

face meteorology and the full water column, as well as some of the larger scale

properties of the mesoscale field. The arrays consisted of a surface mooring;

a nearby subsurface mooring; and two intermediate moorings, one approximately

20 km east, and one approximately 20 km south of the subsurface mooring. The

surface moorings were replaced every six months during the two years of LOTUS,

so four surface moorings were used. The subsurface and intermediate moorings

were each replaced annually, making the total number of Woods Hole moorings

during LOTUS, ten. Figure 2a shows the duration of deployment of each mooring,

and Figure 2b shows the position of each mooring. Also during LOTUS, a C. S.

Draper Labs profiling current meter (PCM) was deployed for three six-month

periods in the LOTUS area, by C. Eriksen (Scripps). A description of the PCM-

can be found in section C2, but the data will be detailed elsewhere.

The first eleven months of LOTUS (called year 1) and associated current

meter data are described in Tarbell et al. (1984). The remaining thirteen

months (called year 2) of LOTUS current meter data are presented in this

report. The hydrographic data (XBT and CTD) are described in the individual

cruise reports (see References) and are only summarized here.

Data collection for year 2 began in April 1983, when the entire mooring

array was recovered and replaced by the moorings described here: surface moor-

ing 787 (designated LOTUS 5), subsurface mooring 788, and intermediate moorings

789 and 790. Surface mooring 787 was recovered in October 1983, but due to Ldamage to the replacement discus buoy during deployment, the new mooring, 792

(designated LOTUS 6) was not deployed until January 1984. In May 1984, the

entire array was recovered, ending the data collection phase of LOTUS.

*A. Moorings

Three kinds of moorings were used in LOTUS: surface, near surface, and

* intermediate. Table 1 provides the location and duration of each mooring's

deployment. The mooring diagrams (Figure 3) show six different kinds of sub-

surface instrumentation (see next section) on the moorings. The bottom in the

area is essentially flat and featureless sand and silt, with a nominal depth

of 5368 m (corrected).

The two intermediate moorings (789 and 790) and the near-surface mooring

(788) are constructed entirely of chain and wire rope, except for a shortlength of braided nylon line directly under the acoustic release.

The surface moorings (787 and 792) are chain and wire rope in the top

2000 m to guard against fishbite, and braided nylon beneath for compliance.

The surface moorings are slightly longer than the water depth, but the constant

presence of a current at the site prevents any slack and subsequent entangle-

ment in the mooring line. Tension measurements just under the surface buoy

usually show 2000-4500 pounds tension, depending on the large-scale current

field. Local wind and current effects at the surface have little effect on

the mean line tension. See also Clay (1983).

All moorings recovered from the site have shown evidence of fishbite

* (teeth marks in or even removal of the PVC jacket on the wire rope), especially

in the 500-1000 m depth range. Further information on fishbite may be found

in reports by Prindle (1981, 1982).

B. Instrumentation

1. Current Meters

The primary current meters used in the LOTUS experiment are Vector

Averaging Current Meters (VACM) and Vector Measuring Current Meters (VMCM)

(Figure 4). They differ mainly in their flow-sensing elements: the VACM uses

a Savonius rotor and a vane to give speed and direction which are resolved

against an internal compass to East and North components whereas the VMCM uses

*orthogonal cosine-response propellers that sense directly the flow components

which are then rotated, relative to an internal compass.

Both instruments provide a continuous vector-averaging during a recording

interval by sampling 8 (VACM) or 4 (VMCM) times per rotation of the sensor;

both cases correspond to sampling and vector-averaging at least several times t

per second. 4

The recording interval of an instrument depends on the planned deployment

period of the mooring. The one year moorings had current meters with recording

intervals of 7.5 minutes whereas those on the 6 month (surface) moorings had

3.75 minute recording intervals.

Additional technical information on the VACM and its sensors may be found

in Fofonoff and Ercan (1967), McCullough (1975), Payne et al. (1976), and Dean

(1979). The VMCM is described in Weller and Davis (1979). Intercomparisons of

these instruments are given in Halpern et al. (1981).

Both current meters record on Phillips-type cassettes by means of Sea

Data recorders. The cassettes are removed ashore and transcribed to 9-track

computer tapes for further processing.

During the second year of the LOTUS experiment, a General Oceanics cur-

rent meter was deployed adjacent to the top VACM on mooring 790, for testing

purposes. The General Oceanics current meter uses a large vane and compass to

measure direction, and the speed is derived from instrument tilt. Details of Lthis current meter intercomparison will be described elsewhere.

Temperature measurements were made by both the VACMs and VMCMs. The VACM

temperature sensor (a thermistor embedded in its end cap just above the vane)

has an accuracy of approximately .019C (Payne et al., 1976), and resolution of

.07 x 10 C (Tarbell et al., 1979). Some VACMs have either a pressure sensor

(VACM-P) (located just above the vane) or a pair of thermistors separated by

approximately one meter to give the vertical temperature gradient (VACM-DT)

(Dean, 1979). The time response of the end-cap thermistor is approximately

94 sec, whereas the thermistor system used in the VACM-DT has a 12 sec response

(Levine, 1981); this difference could affect certain kinds of data comparisons.

Only the temperature and pressure sensors were calibrated prior to

deployment; the rotor and vane weights, sizes and bearing clearances were

simply kept within narrow specifications to permit the nominal calibrations

(McCullough, 1975) to be used.

The VMCM also senses temperature with a thermistor embedded in the upper

end cap of the pressure case. According to the manufacturer's specifications ra calibrated thermistor has an accuracy of .010C. For the temperature range

selected for the LOTUS VMCMs (170C to 300C) the resolution of the system is

1.4 x 10- 3C. The statistics tables (p. 158) give the instrument identifica-

ticn numbers for each depth and mooring.

2. VMCM Variations

The VMCM is a relatively new instrument still undergoing tests to perfect

its long term performance. One component of the instrument which was under

examination was the material used for the orthogonal propellers. Propellors

fabricated of black Delrin (a Dupont Co. Acetal homopolymer resin) have had the

best performance record, and were used on the LOTUS 5 and 6 VMCMs. The color

black was chosen to decrease their visibility and thus discourage any interfer-

ence by fish.

During the first year of LOTUS, various antifouling compounds were used

on LOTUS 3 propellers, and nothing used on those of LOTUS 4. A significant

difference in the amounts of growth on LOTUS 3 and LOTUS 4 was observed,

consequently, antifouling agents were used on both LOTUS 5 and LOTUS 6 VMCMs. -

LOTUS 5 and LOTUS 6 VMCMs were made using dovetail joints to fit the

rotor blades into the hubs, as dovetail joints increased rotor life on LOTUS 4

VMCMs. Balancing the rotors also contributed to increased instrument life,

and so all rotors on LOTUS 5 and 6 VMCMs were balanced.

Another aspect of the VMCM under study is the type of bearings used on

the propeller shaft. All LOTUS 5 VMCMs had a 1/4" propeller shaft, used 1/40

bearings and had a type 18-8 stainless steel retainer ring, first used in

LOTUS 4. Instruments shallower than 75 meters had bearings made of type 440

stainless steel, and instruments deeper than 75 meters used bearings made of

type 316 stainless steel.

The LOTUS 5 and 6 VMCMs at 75 meters and deeper were identical. The

shallow instruments on LOTUS 6 were modified slightly to increase the durabil-

ity of the instruments. The propeller shaft and bearings of these instruments.-

were 3/8" instead of 1/4". Type 440 stainless steel was used on the 5, 10,

and 25 meter instruments, and the 50 meter instrument had bearings coated with

Armaloy. The shallow instruments used in LOTUS 6 also had anodes, made of

type 6-32 aluminum acorn nuts, bolted to the ends of each propeller shaft. The .

16

aluminum was oxidized more readily than the stainless steel of the bearings, so

functioned to lessen the corrosion of the bearings.

Table 2 summarizes the differences between the LOTUS 5 and LOTUS 6 VMCMs.

3. Aanderaa Temperature Recorders

Both of the second year LOTUS surface moorings (LOTUS 5 and LOTUS 6) had

three 100 m long thermistor cables with Aanderaa TR-l or TR-2 recorders situ-

ated to give 10 m resolution between 50 and 350 m. This placement of the ther-

mistors was planned to allow the depth of the mixed layer to be monitored.t

The temperature range of the thermistor chains used during LOTUS was

10.086 to 36.04OC; the resolution was .0250C. The 6 month deployment period

and the limited tape capacity restricted the sampling interval to 60 minutes.

Calibration of the thermistor cables was performed at WHOI. The proce-

dure involved immersing the entire cable into a calibration bath and then

decreasing the bath temperature in a series of steps from 300 to 100C. Cali-

bration coefficients were calculated for each thermistor using a second order

polynomial.

The data return from LOTUS 5 and LOTUS 6 Aanderaa temperature recorders

. was much less than expected. Most of the instruments failed within 50 days of

-" deployment; the primary cause of failure was that the battery packs cracked

and leaked, causing loss of poar; in one case the encoder went bad. The

- batteries were manufactured by Leclanch4.

There was only about 30 percent overall data return from the LOTUS 5

• Aanderaas. However, most of the thermistors on the 50-100 m instrument worked

for about six months, so there was fair data coverage for that time period and

* depth range. The overall data return for LOTUS 6 (22 percent) was only a

little worse than that for LOTUS 5, but only one thermistor of 33 produced a

record longer than two months. The rest of the data was short pieces, all of ..-

- which occur in the first two months of the deployment. Due to the small

amount of data available, a composite plot of the Aanderaa temperature data

will not be presented.

4. Vector-Averaging Wind Recorder

The Vector-Averaging Wind Recorder (VAWR), a modification of the Vector

*Averaging Current Meter (VACM), has been used at WHOI for making high quality,

long duration observations of meteorological parameters from moored oceanic

buoys. The VAWR contains averaging and recording circuitry that computes

vector-averaged wind velocity. The VAWR also allows for recording additional

measurements such as: air and sea temperatures, barometric pressure, relative

humidity, insolation, and compass orientation.

The VAWRs used in LOTUS were fitted with several different sensors. The

integral direction and speed sensors used in LOTUS 5 were developed for use in

the Coastal Ocean Dynamics Experiment (CODE) (Dean and Beardsley, in prepara-

tion). All sensors were positioned on the discus buoy's tower so that interac-

tive effects such as shading, and wind diversion would be minimized. The rela-

tive humidity measurement was adversely affected by salt that accumulated on

the sensors, and the barometric pressure measurement was affected by the wind.

Table 3 gives a summary of the meteorological sensors used in LOTUS 5 and

6; the values (mostly estimates) in the "system accuracy' category are par-

tially due to environmental effects on the sensor, and partially due to mechan-

ical and electronic system effects.

Because of the difference in planned lengths of deployment, the VAWRs in

LOTUS 5 and 6 used different sampling rates. VAWR No. 141 (LOTUS 5) recorded

data averaged over 7.5 minutes, but since VAWR No. 177 (LOTUS 6) was to be out

for only four months instead of seven, a sampling interval of 3.75 minutes was

used. These sampling rates are long enough to average out the bulk of buoy

motion, but short enough to retain high frequency variability in the meteoro-

logical data.

As well as having a VAWR on each LOTUS surface mooring, there was also an

independent set of sensors that telemetered their data via the ARGOS system.

On LOTUS 5 there was also a meteorological recorder (MR) that measured similar

parameters to those measured by the VAWR, using different sensors (Payne, in

press). For additional information on the meteorological data acquisition

systems used in LOTUS, consult Deser et al. (1983).

C. Other Data

1. XBT and CTD

During each cruise to the site, an XBT section was made along approxi-

mately 70OW from about 40ON to 340N, and CTD stations were made near the moor-

ings and around the array. The XBT and CTD data are all given in detail in

each cruise report.

The positions of all the CTD stations taken during the second year in the

LOTUS area are shown in Figure 5. For general reference, Figures 6a and 6b

show typical CTD profiles at the LOTUS site for each season. Below 200 m there

is little seasonal influence, but the mesoscale effect of a variable eddy field

is visible especially in the main thermocline.

2. Profiling Current Meter (PCM)

The M.I.T.-Draper Labs Profiling Current Meter (PCM) is a programmable

moored upper ocean current and density profiler capable of making over 1000

repeated profiles from 20-200 m depth along the upper section of a barely sub-

surface mooring; Dr. Charles Eriksen (now at Scripps) is the Principal Investi-

gator for the PCM. The PCM is free to move along the guideline portion of its

mooring by adjusting its buoyancy using a computer controlled electric oil

pump/swim bladder assembly. As the instrument ascends, it measures current

with a spherical 2-axis electromagnetic current probe, temperature with a ther-

mistor, electrical conductivity with an inductive cell, and pressure with a

strain gauge. Samples are accumulated at 1 Hz and averaged into pre-programmed

depth bins, typically 5 m thick. Magnetic field and tilt information are used

to vector-average horizontal current data. The instrument maintains a rise

rate of 10-15 cm/s during ascents so that profiles can be repeated as often as

I hour. Battery and tape recorder storage provide the principal limitations to

the duration of the PCM deployments. The instrument is not from Woods Hole and

the data are not presented here.

3. Engineering Data

The VACM pressure sensors on the subsurface moorings provide useful

engineering data: during low current periods they confirm the nominally cal-

culated depths of instruments, and during high current periods they help relate

the currents to mooring tilt-over.

Surface mooring 787 (LOTUS 5) nad, at the base of the discus buoy's rigid

bridle, a tensiometer that telemetered data to the ARGOS system. This tensi-

ometer stopped working after approximately two months, so there is no tension

data available between June and November 1983. The LOTUS 6 surface mooring

was deployed in January 1984 with a tensiometer at 267 meters, as well as the "

telemetering tensiometer at the base of the rigid bridle. Both instruments

functioned until final recovery of LOTUS in May 1984.

D. Data Quality

Figure 7 shows all the data considered good that were returned from the

two years of LOTUS. Bar graphs are for current meter data, meteorological data

and Aanderaa thermistor chain data. Table 4 lists problems encountered causing

instruments to have less than 100 percent data return.

E. Data Processing

Time series are identified by a three digit mooring number, a sequential

S instrument position number, a letter to indicate the data version, and a number

to indicate the time sampling interval of that data set. Sequential position

numbers, if preceded by an "S', indicate that the instrument was set on the

surface buoy. 787SIElDG24 is the first instrument set on the surface flotation

of mooring 787. It has been edited to the Eth version and was sampled at one

point per day from a Gaussian filter having a half width of 24 hours. Simi-

larly, 7892C450 is the second instrument on mooring 789. It has been pro---

cessed to the Cth version and is sampled every 450 seconds (or 7 1/2 minutes).

Data from cassettes were transcribed onto 9-track magnetic tapes, con-

verted to scientific units, and edited to remove launch and retrieval tran-

sients and erroneous data values. All the directional values have been con-

verted from the Magnetic North coordinate system to True North.

Low passed versions of the data series were formed by passing the data

* through a Gaussian filter with a 24 hour half-width, then subsampling the re--

* sultant series once a day. The unfiltered series all start at noon, therefore

the filtered series also present noon data points.

F F. Data Presentation

Following the text, composite plots summarizing the second year's data

are presented. Current meter temperatures, current meter speeds, and progres-

sive vector diagrams of the current meter data are shown.

The data are broken into three groups. The meteorological data are pre-

sented first; time series, histograms and spectra for the VAWRs (Vector

Averaging wind Recorders) are shown. The second group of data is the current

meter data for the two second-year surface moorings. The third group is the

data from the near surface moorings and two subsurface moorings, which are

presented by depth. All the time series are followed by the histograms, then

by the spectra in each group. The statistics for all the instruments are pre-

sented at the end of the data section.

The following is a brief description of the different plots.

Progressive Vector Diagrams

Current vectors from the filtered time series are placed tail-to-head so

as to show the path that a particle in a perfectly homogeneous flow would have

traveled. The plots for each time series begin with an asterisk and are anno-

tated monthly. Moorings 787 and 792 were set consecutively, so the progressive

vector diagrams representing data from mooring 792 are shown on the same page

as plots from mooring 787. In those cases where there is a time separation of

greater than a few days the positioning of the following Provec is arbitrary

but subjectively reasonable.

Variables vs. Time Plots

Individual variables and the stick plots are plotted against time from

* one day Gaussian filtered time series.The plots have been done to the same scales to facilitate comparisons.

In the case of the deepest temperature measurements, the temperature has been

plotted on two scales, first the general scale then at a scale selected for

" that data set, which shows details. Pressures have been plotted against a

negative decibar scale to invert the trace to facilitate comparisons with

temperature and speed.

The plots for time series from consecutive moorings 787 and 792 are

combined for appropriate depths.

Histograms

Data are taken from the unfiltered time series. For each class interval

the frequency value is a percentage of the total count. For the 'weighted

direction' histogram each value is weighted by the corresponding speed value

* before assigning to a class interval. All histograms have 50 class intervals

* per inch.

The plots have been done to the same scales to facilitate comparisons.

* In the case of the deepest temperature measurements, the temperature has been

-- *--

28

plotted on two scales, the general scale as indicated below, then at a scale

selected for the individual data set, which shows details.

Spectral Plots

Table 5, in the Spectra section of this report, shows the exact number

of cycles per piece and number of pieces used to create the spectra.

Generally speaking the 225 second sampled current meters have a piece length

of 32000 points. All LOTUS 6 instruments had 1 piece used, and LOTUS 5 was

evenly split between 1 and 2 piece spectra. The year long subsurface and

intermediate current meters have four 16000 point pieces. NOTE: No prepro-

cessing (e.g., prewhitening or windowing) has been done to any spectra, so

these plotted results should not be used for any detailed scientific analyses.

Statistics

The statistics are created from the unfiltered time series. See Volume

XVII (POLYMODE Array II) of this series for a description of the various types -.

of statistical parameters.

The Long-Term Upper Ocean Study (LOTUS) was a two-year field experiment near 34*N, 70 0 W,designed to acquire a continuous set of measurements of currents and temperatures in the upper,open ocean together with local hydrography, meteorology, and mesoscale oceanographic features.The first scientific moorings were -deployed in May 1982. The first year of mooring data, frommay 1982-April 1983, is presented by Tarbell, Pennington and Briscoe (1984, WHOT Tech. Rept.84-36). The second year of mooring data, from April 1983-May 1984, when the final mooring recoveryoccurred, is pr(. sented here.
