Objectives

Recover and redeploy eight moorings. Telemeter data from 4 CPIES. Complete 40 
CTD casts (two sections across current). Occupy one continuous ADCP transect 
across the current.



Challenges 

We had four problems that made for a challenging start to the cruise. (1) Our 
first container had not cleared customs, despite that our mooring technician 
had arrived the week before to handle local shipping issues. As a result, the 
container was not received dockside until the afternoon of the day we sailed 
(3rd November, 2011). (2) The Scripps CTD air freight was also delayed and 
eventually picked up during our first unscheduled port visit on the 5th. (3) 
The first mooring became wrapped around the bow thruster during recovery 
operations. We lost instrumentation and had to return to port (5th) to have 
divers clear the thruster. (4) Our second container was delayed until 9th 
November, when we returned to port for a second unscheduled visit to load it. 
In contrast to the Knorr, Melville does not involve the bosun during mooring 
operations, nor assign crew to man the stern winch or A-frame. As a result, 
science parties need to provide two additional technicians for mooring 
cruises scheduled aboard Melville. A student can be trained on the A-frame, 
but the winch and capstan are integral to the safety and success of 
operations and need people with experience.

We had persistent difficulty with acoustical operations throughout the 
cruise. This adversely affected (1) communications with mooring releases 
during both recovery and deployment (triangulation), (2) collection of 
telemetry data from the CPIES, and (3) quality and quantity of ADCP data. 
Communicating with other PIs who have sailed on Melville in the past, and 
from my own previous experience, these acoustical issues were abnormal. The 
Chief Engineer and myself conjectured that the very light fuel load, on 
account of an ensuing dry dock period, had the ship riding high, which caused 
increased cavitation under the hull and disruption of the acoustics. The 
Chief estimated the ship to be riding order feet higher than typical and the 
stern slapping and snap rolling was the worst I have experienced.

Despite these setbacks, we fulfilled the science objectives, aside from some 
lost mooring instrumentation and some data loss due to poor acoustics during 
CPIES telemetry. 



Narrative 

We left Port Elizabeth on 3 November at 16:00 to arrive at site P1/CTD01 at 
02:00 LT the next morning. A CTD cast was conducted (depth 60 m). Tide gauge 
P1 was not recovered. Next we recovered mooring A, only to have it wrap 
around the bow thruster. Two releases were lost because the line was cut and 
we returned to port to have divers clear the thruster. We recovered mooring B 
successfully on 6 November and occupied CTD stations 02-05. The top 
float/ADCP on mooring C had become loose in November 2010, and on mooring D 
in September 2011, and both were picked up by RV Africana. Upon recovery of 
the rest of the mooring C on 7 November we found the 2nd float and Nortek 
current meter lost. We recovered mooring D the same day, with no losses and 
occupied CTD stations 06-08. Next we recovered mooring E successfully and 
conducted CTD09 before returning to port for a second time to collect our 
remaining gear. Back at sea we picked up the inshore end of the ACT line 
again, deploying the tide gauge P1 and moorings A-E without adverse incident, 
occurring CTD stations at night. On 15 November we recovered mooring F and 
attempted CPIES telemetry with limited success owing to poor acoustics. Next 
day we redeployed F and continued on to recover and redeploy G, conducting 
CPIES telemetry and CTD stations out to the end of the line at P5. We 
conducted a synoptic CTD section from site P5 (CTD20) all the way back along 
the ACT line, delayed by a kink in the CTD wire and retermination on 21st 
November. Finally, we conducted a non-stop underway ADCP section back out to 
P5, before heading north and into Durban for final port stop.



ADCP Report

Melville is equipped with two hull-mounted ADCPs of frequency 75 Hz (range 
about 600-800 m) and 150 Hz (range 200-300 m). Standard UHDAS configurations 
were used, as recommended by Jules Hummon, with collection of narrowband 
pings only throughout the cruise. This recommendation is due to known bubble 
issues on Melville: Air gets trapped in the transducer well and this problem 
was clear from lack of data return during CTD casts on our cruise, despite 
the strong current which we hoped might help flush the air out.

We noticed a bias issue with the underway data, due to bleeding of ship 
velocity into the ocean velocity data (see below figure)

LADCP Setup:

Full water column velocity profiles for the ACT November 2011 cruise were 
collected using a hybrid 150/300kHz Workhorse configuration.  Most of the 
instruments, cables, and related equipment were supplied by Dan Torres of 
Woods Hole Oceanographic Institution, with two spare star-cables on loan from 
NOAA’s AOML.  A total of three profilers were on board.  The 150 kHz 
prototype (s/n 13656) and one of the 300 kHz workhorse monitors (s/n 10417) 
belong to WHOI.  The third 300 kHz workhorse monitor (s/n 6820) belongs to 
the University of Miami.  Two custom-made 48-volt deep-sea batteries were 
supplied by WHOI as well.  The two Workhorse ADCPs were mounted on a 12-
bottle CTD rosette, with mounting brackets for the ADCPs and battery provided 
by Scripps Institution of Oceanography.  The upward-looking ADCP was mounted 
near the outer edge of the rosette, situated above the upper rim of the 
frame.  The downward-looking 150 kHz ADCP was mounted in the center of the 
frame; with the transducer face about 10cm off the bottom.  The WHOI-owned 
300 kHz workhorse was originally intended as a spare, with the UM workhorse 
serving as the primary upward-looking ADCP.  After initially trying to mount 
the UM ADCP, I decided to switch to the smaller-footprint workhorse from 
WHOI.  The UM unit has a sentinel-style housing, which is about twice the 
length of the WHOI unit.  The rosette had only one clamp available for 
securing the upward-looking ADCP.  Additionally, the proximity of the Niskin 
bottles made it impossible to lower the height of the transducer head to a 
safe distance.  Ultimately, I felt it was safer to use the monitor-style 
workhorse, given the rosette size and configuration. 

The sea-battery was initially secured adjacent to the downward-looking ADCP 
using ratchet straps.  After returning to Port Elizabeth to pick up late-
arriving equipment, the battery was placed in a stainless steel box secured 
to the rosette frame.  Both ADCPs were wired to run off a single battery pack 
using the supplied star-cable.

The 150 kHz ADCP was configured for 16 16-meter bins, 10 meter blanking 
distance, and an ambiguity velocity of 350 cm s-1.  The 300 kHz ADCP was 
configured for 20 8-meter bins, zero blanking distance, and an ambiguity 
velocity of 350 cm s-1 (though the instrument limited this value to 330 cm s1).  
The units were configured for staggered single-ping ensembles; the upward-
looking ADCP was set to 1 sec ensembles, and the downward-looking ADCP was 
set to burst-sample every 2 seconds with 0.8 seconds between pings.  
Measurements were saved in beam coordinates, with 3-beam solutions and bin-
mapping disabled.  The upward-looking ADCPs were running firmware version 
51.36, while the downward-looking ADCP was running version 51.40.


Data Acquisition Setup:

Inside the main lab of the Melville, a dedicated laptop running Windows XP 
with two USB-serial ports was set up as the primary data acquisition 
platform.  Two separate instances of BBTalk were run to communicate with the 
instruments.  Data files downloaded to the laptop were transferred to my 
laptop via shared network drive for processing and archiving.  A Soneil 
4808SRF was used as the primary battery charger.  The supply was programmed 
to output 58 Volts.  The charger was plugged directly into the battery for 
recharging between stations using a third cable.  Two long ADCP 
power/communication cables were set up to program the instruments and 
download data.  Each cable was connected to a standard RDI-supplied 48 Volt 
power supply, which powered the instruments when the battery was disconnected 
for charging.


Deployment and Recovery:

Lowered ADCP operations began on November 4th, 2011 with a “test” cast near 
the beginning of the main transect line in 60 meters of water.  No 
operational problems were found with the hybrid setup.  The first real 
station cast took place soon after, around 01:00 UTC.  Initial operations 
proceeded slowly at first as the two LADCP shift operators needed to 
familiarize themselves with the equipment and procedures.  CTD/LADCP casts 
were somewhat infrequent for several days, as mooring operations took 
priority, with two return trips to P.E.  As they became more comfortable with 
the equipment, the typical deployment procedure was as follows:

  • About 15-20 minutes prior to arrival on station, the LADCP operator shuts 
    off the battery charger and reconnects the battery to the star-cable on 
    the rosette.
  • The operator wakes up the two ADCPs using RDI’s BBTalk terminal program.
  • Internal clock, memory and instrument voltage check are made.  Clocks are 
    synchronized to the ship’s GPS.
  • The appropriate command file would then be sent to the instrument to 
    initiate sampling.  The output from this operation is captured to a log-
    file.
  • Once the ‘cs’ command was sent, the operator would listen for audible 
    ‘pings’ from both ADCPs to verify operation.
  • The operator would then replace the vent plug on the battery, disconnect 
    the two serial cables, and insert the dummy plugs.

The operator then notes the time and position for the beginning of the cast, 
the maximum CTD depth, and the end of the cast on the log sheet.  Upon the 
safe recovery of the rosette, the operator would begin the recovery 
procedure:

  • Once the rosette is secured on deck, the operator connects the two serial 
    cables to the instruments.  The ‘break’ command is sent to halt pinging 
    and close out the data files.
  • After verifying the battery charger is off, the operator would connect 
    the charger cable directly to the battery and open the battery purge 
    port.
  • The battery charger is powered on as soon as possible to maximize the 
    time available for charging.
  • The instrument baud rate is changed to 115,200 bps to minimize the 
    download time.
  • The most recent good data file is transferred to a temporary cruise 
    directory on the acquisition computer.
  • The operator copies the downloaded data files to a separate folder, 
    labeled by station number.  The files are renamed here using the cruise 
    convention: ‘ACT0410_DN_nnn.000’ or ‘ACT0410_UP_nnn.000’ where ‘nnn’ is 
    the station number.
  • The baud rates are changed back to 9600 and the ADCPs are powered down.

The main transect line contained 22 CTD stations, starting at mooring ‘P1’ 
and ending at mooring ‘P5’.  CTD/LADCP casts were done up to station 9 during 
the first mooring recovery period, November 4th through the 8th, before briefly 
returning to port.  A second series of consecutive casts along the same 
transect line began at station 1 (at site P1, cast number 10), on November 
10th at 08:47 UTC, ending at station CTD-20, near station P5 (cast number 31) 
on November 20th at 01:09 UTC.  The third series of CTD/LADCP casts began with 
cast number 32 on November 20th at 08:22. Continuous casts were then made back 
up the transect line towards P1, ending on November 23rd.

There were three incidents during CTD operations that resulted in aborted 
casts.  Two were winch malfunctions at the beginning of a cast that caused 
damage to the winch cable.  The first occurred on cast 14, where the cable 
was pinched while raising the rosette off the deck.  The rosette was 
transferred to a second winch cable on the starboard A-frame.  There was no 
damage to the LADCP system, but the charger and comms cables had to be re-
located to reach the side A-frame.  Once repositioned, cast 14 was done 
without incident.  The second winch problem occurred at cast number 41 on 
November 22nd at 01:00.  The rosette had been moved back to the original 
winch.  Once again, a cable malfunction led to the package being dropped onto 
the deck from about 3 ft. up.  Fortunately, no observable damage was done to 
the LADCP system.  As before, the rosette was moved to the alternate winch 
and A-frame.

The most significant damage to the LADCP system occurred at cast number 17, 
on November 12th at 14:00.  After the rosette had been brought back on board 
at the end of the cast, the operators noticed that the LADCP was not pinging 
and there was an acrid odor coming from the battery.  Upon closer inspection, 
it was discovered that the 2 ft. 2-pin to 7-pin adapter cable coming off the 
battery cable had completely burned through and was severed.  The impulse 
connector at the battery-star-cable connection had swollen and burned as 
well.  The star-cable segment leading to the battery connector was scored in 
several places up to the main junction.  This was the only visible damage; 
the rest of the cable assembly appeared normal, while both ADCPs appeared 
unaffected.  The battery had clearly shorted out and the high current had 
melted the cable.  It is unclear where the short initially occurred, although 
the most likely explanation would seem to be that there was a leak in the 7-
pin connector where the battery connects to the 2-ft. adapter cable.

The battery and star-cable were rendered unusable.  A spare battery and star-
cable were installed and the system was tested before being re-deployed.  
After examining the data recovered from the 150 kHz ADCP, it was found that 
the battery had failed shortly after the beginning of the upcast at a depth 
of about 3000 meters. 

Another unusual behavior in the LADCP system was the occasional, somewhat 
random communications disruption.  The instrument would become unresponsive 
when certain routine commands were sent, most commonly during baud rate 
changes or when uploading data from the recorder.  The cause of these 
disruptions is unclear, and the solution usually involved disconnecting the 
instrument from the star-cable and running a direct power/comms cable to it.  
This problem did not cause any significant delays.

Preliminary processing shows that there was only one cast, number 23, that 
contained some unusual data which caused problems during the LADCP 
processing.  Examining the raw data, there appeared to be some abnormally 
high velocities near the beginning of the cast, especially in the vertical 
component; however, this is not reflected in the error velocities.  
Examination of the downward-looking raw data revealed several missing 
ensembles and timestamp errors that caused the processing software to crash.  
This was resolved by cutting the first 1932 ensembles from the file, which 
allowed the processing to complete successfully. 

Additionally, there were a few casts early on, numbers 5 and 8 in particular 
where the ADCPs recorded very high pitch/roll values, in excess of 30 
degrees, which is the normal cutoff limit in the processing software.  This 
limit had to be increased on cast 5 in order for the processing to complete 
successfully.  This cast also did not record any clear bottom-track data.  
The resulting profile is therefore rather questionable.

As might be expected, using the 150 kHz prototype in very shallow water did 
not always produce solid results, especially when not using CTD depth or 
bottom tracking.  The LADCP software had trouble distinguishing the bottom 
reflection from other reflections and high backscatter.  Overall, however, 
the 150 performed well, with consistent signal strength and range throughout 
the survey.  The same can be said of the 300 kHz unit as well.  This 
particular combo also seemed to be very efficient as well; rarely did the 
battery charger require a substantial amount of time to bring the battery 
back to nearly full-capacity.


Data Processing:

The two raw ADCP data files were first copied to a dedicated laptop for 
processing.  Navigation data were extracted from the uncorrected one-second 
time-series CTD data provided by the CTD operator, downloaded over the ship’s 
network.  Once the files were in the proper directories, the “first-pass” 
processing could be executed.

The initial processing of the raw ADCP data was done using version 10.8 of 
the M. Visbeck & A. Thurnherr MATLAB toolbox, modified by G. Krahmann.  The 
‘process_cast(nnn)’ script was run, with ‘nnn’ representing the station 
number, which called subroutines to copy, load, scan in, and run the shear 
and least-squares inverse methods.  About a dozen graphics are generated with 
useful diagnostic information and the final water column profile.  The 
processing scripts required some code modifications, primarily to ensure the 
ADCP and GPS data were properly loaded.  Two small m-files were added: 
‘load_ctd_for_nav.m’ and ‘load_ctd_for_prof.m’ to the local /m directory that 
were called by the ‘prepctdprof.m’, ‘prefctdtime.m’ and ‘prepnav.m’ scripts 
to generate mat-files for processing.  Manual changes to the 
‘cruise_params.m’ and ‘prepare_cast.m’ codes were also necessary to ensure 
that only the navigation data would be used in the first-pass processing, and 
that bottom tracking was disabled.  When the first-pass was finished, the 
operator would note in the log sheet the calculated depth based on the 
integrated vertical velocity and compare it to the maximum depth reported by 
the CTD.

During the CTD/LADCP survey, the casts were re-processed to include the CTD 
pressure record and time-series data.  The inclusion of the CTD depth allowed 
the LADCP software to be far more accurate in determining the bottom-track 
velocities and masking out data below the sea floor.  The 1st –pass processing 
run was not able to accurately mask out bad data below the sea floor because 
of what appears to be a flawed bottom depth calculation.  Depth from the 
integrated W values appears to be valid, but without CTD input, it is 
ultimately in error, therefore the calculated velocity profiles are 
substantially deeper than they should be.


Summary:

Overall, the prototype 150 & 300 kHz ADCPs performed quite well, with no 
major communication or power issues.  In total, 50 LADCP profiles were 
collected.  Processing shallow water casts (less than 100 meters or so) 
proved somewhat difficult due to errors in bottom detection. Both units 
experienced significant drops in profile range at depths below 2000 meters, 
down to around 50 meters for the 300 and 150 meters for the 150 kHz unit at 
the 3000 to 4000 meter range.  Many stations appeared to have somewhat high 
error velocity in the downward looking profile immediately after the rosette 
begins the upcast, possibly related to turbulence in the wake of the rosette.  
As expected, the change from a dual-300 kHz system to the 150/300 hybrid 
produces better results overall, with greater range at depth and less 
occurrence of the “runaway shear” profile.  The cause of the battery short 
remains unclear.  Some improvement to the 1st –pass processing would seem to 
be needed to more accurately determine the true water depth.

;  WH150kHz master/downlooker deployment script 
;  for *new* lowered 150 from RDI (ten years in the making!)
;==================================================
; Changes from previous deployment scripts:
; (1) "wm15" command for LADCP mode and no longer need "L" commands
; (2) only commands that change defaults are included (EA,ES etc removed)
; (3) data collected in beam coordinates (allows better inspection of 
;     raw data and 3-beam solutions if necessary)
; (4) staggered single-ping ensembles every 0.8/1.2 s (Andreas has seen
;     bottom-interference in WH300 data in Antarctic - seems unlikely for
;     Abaco, but does not lose us pings).
; (5) 16 x 16 m bins - for a range of 256 m (could try less for casts > 3500 
m)   
;
; Changes made after email discussions with Eric and Andreas, April 2008
; and looking at Dan Torres' command file for his new wh150.
