Abstract

We describe the current-meter data collected from 4 moorings

(11 current meters) in the vicinity of the Blake-Bahama Outer Ridge.

These 12-month records document both mean and eddy activity of the deep

western boundary current of the North Atlantic, near 300N. In addition

the temperature records show large-scale, westward propagating eddies in

which the ocean above the thermocline actively affects the abyssal jet.

EXPERIMENT DESCRIPTION

In May 1977, the Moored Array Group set out 5 moorings with 15

temperature recording VACM current meters and 2 M.I.T. temperature-

pressure (TP) recorders in the vicinity of the Blake-Bahama Outer Ridge

(near 30.5*-310 N, 73.5*-76.5*Wsee figure 1). The duration of the obser-

vations was twelve months. The purpose was to provide the first long-term

measurements of the deep western boundary current in the North Atlantic,

sometimes known as the Western Boundary Undercurrent. Supporting hydrographic,

geo-chemical, radio-chemical, and XBT data were collected by Rhines on

cruise 31 of R/V Oceanus, and during the mooring pick-up, cruise 100 of

R/V Atlantis II. At the deployment, cruise 66 of R/V Knorr, hydrographic

data were collected by Larry Armi.

The 12-month mean currents, figure 4, show the abyssal flow, with

speed increasing downwards (below the thermocline). The deepest measure-

ments (200 m above bottom) lie close to topographic contours. The bottom

slopes steeply in this area. The mean path of the abyssal current thus

follows the deep topographic boundary on its way south.

As one moves upward from the bottom, however, the mean currents

veer significantly. This veering is always in a sense appropriate to

allow some of the flow tc rise up and over the topographic obstacles.

At mooring 618 for example, the flow has passed southwestward along the

gentle continental rise north of 320N. Then, it is confronted with a

major obstacle, the Blake-Bahama Outer Ridge, which forces it to turn

southeastward. The convergence of the isobaths suggests a thinning and

acceleration of the flow.

The current only partially negotiates this turn, flowing up and

over the Ridge crest at shallower levels. Even in ignorance of the topo-

graphy, we would know that clockwise veering as one moves upward requires

upward vertical velocity, from Bryden's (1976) rewriting of the thermal

wind equation. The vertical velocity inferred in this way from the veering

is indicated in figure 4.-1

The mean current in the deep jet reaches 21 cm sec at 3800 m,

on the eastern flank of the Ridge (record 6183, figure 6) decreasing upward-i

to 5 cm sec at 2000 m (often taken to be the 'level of no motion' in

classical studies). Combined with the hydrography (e.g. the August 1977

section of Oceanus 31, figure 2) we can provide estimates of the volume

transport of the abyssal circulation.

ix *-

The time-series from the deep jet, page 18, show the mean flow-i

standing out well above the eddies. The jet reaches speeds of 40 cm sec

and, occasionally, shuts off entirely.

Eastward of the jet core, we placed mooring 620 to catch the sea-

ward fringe of the current. In fact, the 12-month mean velocity at this

point was north-westward at all levels (figure 4). Comparing with figure 2,

we see that the broad region of sloping isotherms, which would suggest

a broad southward flow, is atypical. The instantaneous current (page 19)

was southward (i.e., atypical) during this section, and during several

others that we have taken. (The important section of Amos, Gordon and

Schneider (1971) also resembled this one.) This underlines the value

of long-term current measurements in augmenting hydrographic determinations

of transport. The mean southward current is thus more barotropic and more

narrowly confined (laterally) than the classical, purely hydrographic,

determinations suggested. One of a number of chemical tracer sections

from Oceanus-31 is shown in figure 3. This shows the (bomb-test)tritium

concentration, forming a strong, narrow core in the abyssal jet (Jenkins

and Rhines, 1979).

On the west side of the Ridge, mooring 617, the mean flow involves

a downward vertical velocity, complementary to mooring 618. Otherwise,

the flow is basically along depth contours. Downstream, at mooring 616

the jet once again encounters a converging, leftward bend in the isobaths,

and the vertical velocity is positive, with the upper levels negotiating

the turn less perfectly than the deep layers.

The deep flow at the seaward end of the array, mooring 620, is

oscillatory with roughly 6 month period. This is clearly a different

new regime, from that of the jet. The northwestward mean is consistent

with the schematic circulation diagram of Worthington (1976), which has

a strong, deep gyre beneath and south of the Gulf Stream, flowing north-

westward in this area.

The single upper-level current meter, 6171, at 600 m, shows a 'parade'

of warm and cold eddies passing westward across the region (page 25 and

page 17). Some of the cold eddies are well documented as Gulf Stream rings

by Richardson (1969). These alternate with larger warm features in

which the 180 water content is particularly great.

x

....__ _ _..--- .

The upper-level mean flow at 6171 is strongly westward, in nearly

the same direction as the isobaths and the deep flow. This may represent a

concentrated inflow to the Florida Current, which is known to entrain

considerable amounts of water between the Florida Straits and Cape Hatteras.

The temperature time-series show unexpected coherence in both hori-

zontal and vertical. Despite the 0(100 km) spacing of the moorings one

sees in page 28 a systematic westward phase motion of temperature features,

across the array at 2000 m, at speeds of order 3 km day-1 . The hydrographic

sections verify that very large-scale warm eddies (of order 300 km in

east-west extent) were present, accounting for this coherence. In this

special region, where the southward flowing boundary current turns westward,

its path temporarily coincides with the sense of westward propagation

that prevails on a $-plane.

The vertical interrelationships of temperature show coherence

between 600 m and 2000 m, page 25, and coherence of certain events between

these levels and the deeper water, pages 24, 25, 26. The most striking

effect is the penetration of 'sudden warmings' down through the water

column, e.g. at the end of July at mooring 618. This occurs at the leading

front of large, warm eddies of 18' water, as it passes westward across the

moorings. This deepening of the thermocline evidently imposes downward

vertical velocity right to the sea floor (The downward motion is made

possible by the steep slope of the ridge.)

The corresponding velocity events, page 18, current meter 6183, show

the deep jet to switch off suddenly during the warm pulse. It is uncertain

whether this represents a seaward meander or a pulse-like event in which

the jet ceases over the entire cross-section. In either case, it demonstrates

how eddies above the thermocline can induce major disruptions in the deep

flow. After this 'shock' the deep jet quickly recovers, surging to a

speed of 40 cm sec -1 , the fastest of the entire year.

Final resolution of the coherent structure of the jet pulsations

will, regrettably, not be possible from this data set; mooring 619, which

was set 16 km northeast of mooring 618 to provide such information, was silent

during attempts to transpond with it in August 1977 and again in May 1978.

a xl

It is speculated that the height, stiffness, and drag of the mooring

(bottom to 600 m depth, with 70 glass balls) led it to drag southeastward

in the unexpectedly strong currents. Acoustic searches were carried out,

extending 10 miles upstream (NW), 40 miles downstream (SE) and back, on

the May 1978 pick-up cruise, R/V Atlantis-II-100.

Instrumentation

The instruments represented in this data report are the Vector

Averaging Current Meter (VACM) and a temperature and pressure recording

device (T/P) developed at M.I.T. (Wunsch and Dahlen, 1974). The VACM

uses a Savonius rotor to measure water speed and a vane and internal

compass to measure direction. East and North components are calculated

from the compass and vane values 8 times per rotor revolution. The

components are accumulated over the recording interval resulting in

vector averaged velocities.

The VACM has a thermistor embedded in its end cap just above the

vane. Temperature accuracy is approximately .01°C (Payne et al., 1976).

The top instrument on each mooring was equipped with a pressure sensor.

The T/P contains a thermistor and pressure sensor. Temperature

accuracy is about .010 C; pressure accuracy is .03% of sensor full scale.

Both the VACM and T/P contain a crystal oscillator with an accuracy

of ± 1 second per day to set the time base and record on Phillips-type

cassettes with Sea-Data recorders.

Data Quality

Except for mooring 619, which was lost, data recovery was excellent.

There were two problems, both with pressure: in record 6161 the pressure

signal drifted 12 decibars or 11 months; in record 6181 the pressure

signal ceased after 4 months.

Data Processing

The cassettes were transcribed to 9-track computer compatible tapes,

and the data were converted to scientific units, edited to remove launch

and retrieval transients, and linearly interpolated across missing or

erroneous data cycles.

The data are identified by a mooring number (here 616-620), a

sequential instrument numbered from the surface down (e.g., 6163 is

the third instrument down on mooring 616), a letter to indicate the

data version (e.g., 6163C has been through three editing steps), and

a number to indicate the data interval in seconds for that version

(e.g., 6163C900is the basic data series). 1H in place of the number indicates

a one-hour averaged version, 24 GAU indicates a 24 hour subsampled

version of a Gaussian filtered series.

5t

The T/P data were processed by the T/P processing group at M.I.T.

They are identified by a mooring and instrument number and a data record

time interval.

Data Presentation

The presentations in this report are time series, progressive

vector plots, spectra, mean statistics, histograms, and scatter plots.

Additional details are below. Composite plots appear in the printed

portion of the report. Presentations for individual data files are

presented only in the microfiche portion.

Time Series

The presentations use several averaging times. The 1 hour version

is made by vector averaging the 900 s basic series. To make the 24 hour

series, the basic time series is first filtered using a symmetrical

running Gaussian filter with a half width of 24 hours. The filtering

is sequential and the resultant time series is 48 hours shorter than

the input time series. A simple running hat filter is then applied to

form a series with one data point per day, the point representing the

average from midnight to midnight.

Variables versus time (pages 24-30) and current vectors ("stick

plots") versus time (pages 16-19) are presented. The former are based on

1 hour averaged series subsampled every 4 hours, the latter on the 24 hour

series. Current variables are presented as speed and direction in the

microfiche portion of the report.

Progressive Vectors

Based on the 24 hour series, the current vectors are placed tail-

to-head so as to show the path that a perfect particle in a perfectly

homogeneous fluid would have traveled. The plots (pages 20-23) are useful

for giving an idea of flow regimes and low frequency behavior. Symbols

denote the end of a month.

Spectra

The horizontal kinetic energy (HKE) and (where available) the

temperature and pressure series are displayed as spectra computed from

the basic series.

The horizontal kinetic energy spectrum is half the sum of the

spectra of the east and north components: it has the advantage of not

being tied to a particular coordinate system.

The HKE, temperature, and pressure spectra have units of (cm2 /sec2)/

cph, (oC) 2/cph, or (dbar) 2/cph, respectively. The spectra are all

one-sided, i.e. the area under the spectrum is equal to the variance of

the original record. The spectra are presented as linear-log plots

("variance preserving") in the printed portion of the report (pages 31-42)

and as log-log plots (not "variance preserving") in the microfiche portion.

The current meter spectra are all calculated based on averaging

across four data segments of 4000 points each, followed by frequency-band

averaging across three frequencies with a recording interval of 900 s.

This gives a lowest frequency of (666.7h)- and a highest frequency of

(0.5h)- l. The TP spectra are based on averaging across two data segments

of 4000 points each, followed by frequency band averaging across three

frequencies. With a recording interval of 1800 s this gives a lowest

frequency of (1333.3h)- 1 and a maximum frequency of (lh)- l. No data-

windowing or prewhitening has been done.

TIMSAN, the W.H.O.I. program (Hunt, 1978) used to produce the spectra,

additionally averages the spectra in increasing groups at the higher

frequencies to prevent having to plot thousands of points; this gives

few degrees of freedom (d.o.f) at the lowest frequencies, many at the

highest frequencies. For spectra calculated from 4 pieces with 3 frequen-

cies averaged, there are 24 d.o.f. in the 40 lowest frequencies and

1200 d.o.f. in the two highest frequencies; the 95% confidence limits

corresponding to these two extremes are (.61, 1.94) and (.97, 1.03).

Mean Statistics

The statistics for each variable for the time period shown are

given for the basic series, also the east and north covariance, correlation,

and vector statistics on pages 44-45.

For reference note that a Gaussian random variable would have a

kurtosis of 3 and a skewness of zero.

Histogram

Each variable is plotted as relative frequency of occurrence (in the

basic series) per unit cell width versus amplitude on pages 43-55; the area

under the histogram is 100%. The mean value is marked on the horizontal axis.

Scatter Plots

Scatter plots of north vs. east component, and temperature vs. east

component and vs. north component are shown for each current meter record on

pages 56-77.

The deep boundary current flows southward along the eastern slopeof the Ridge, and returns northward on the western slope. The mooring recordsshow, however, that the long-term mean flow is narrower than would be inferredfrom the region of tilted isotherms (at 620 the 12-month mean is northwest-ward: fig. 4, and page 14).
