2. Confirm that information from the on-screen display are streaming to data files by simulating a dive and checking the raw data files.
3. Check DVCam (DSR25) preferences to be sure that time stamp is in real time (Set the clock to GMT, then set time code: Menu- time code- TC1-free run- time code: make preset; h:m:s).
4. Proceed with pre-dive checkouts
Appendix IV- Pre-deployment Checks
A. Vehicle checks
Are the bridle and umbilical and rig (ties –ropes) secured on the ROV?
Are all the plugs secure?
Are there any tools or other equipment sitting on the ROV?
Does the ROV have good vacuum seals?
Turn power on – is there 240 volts?
Are the video and still cameras working (zoom, tilt, strobe)?
Are the lights working?
Are the lasers working and calibrated?
Are all four thrusters working?
Is the transponder plug moved to the on position?
Have the batteries for the strobes been changed?
B. Console Checks
Has the heads up display been checked for new date, dive id, locations, drivers?
Are new VHS and DVCam tapes in the recorders?
Have the WinFrog .DAT and .LOG files been named for the next dive?
Have the cameras dates and times been checked?
Are the WinFrog I/O devices showing green for the Trackpoint,CSI, Leica, KVH, OSD, DVL?
Appendix V- Transect Checks
A. Start Transect Checks
Activate WinFrog session (Fx button).
Mark ‘Start Transect’ with F10 when habitat is first encountered.
Start video and DVcam tapes recording (hold down rec. and push play).
Enter into Access log: start time (GMT) start position (Lat. Long – Deg, min, dec secs), Start depth.
Push text button to display console information for 5 seconds (also must be done every time a tape is switched).
Periodically check depth of clump weight vs. depth and maintain contact with deck to adjust when necessary.
Record all events with F10- especially when ROV is off transect (i.e. out of suitable habitat or driving complications) and back on transect.
B. End Transect Checks
Mark ‘End Transect’ with F10.
End WinFrog session (Stop button).
Stop VHS and DVcam tapes.
Turn off lasers.
Enter into Access log: stop time (GMT), stop position (Lat. Long – Degrees, minutes, decimal secs), stop depth, number of abalone spotted, notes.
Monitor clump weight depth as ROV is ascending.
Alert pilot of number of turns in cable prior to surfacing.
Appendix VI- ROV Deployment
Minimum of 5 scientists and 2 crew members, comprised of the following:
S1- Reelperson, deck communications
S2- Reelperson/tether manager
S3- sling/wire tender
S4- ROV pilot
S5- Recorder, lab communications
C1- crane operator
C2- clump weight tender
B. Hydrophone deployment
Loosen bolts securing hydrophone pole (S1 or S2).
Hydrophone lowered to vertical position on starboard side using the main winch, and hydrophone mount stays (C2).
Hydrophone stays (2 forward, 2 aft) secured (S1 and S2).
Hydrophone checked for approximate 90º position (using wood block) and secured to side of boat with strap (C2 and S2 or S2).
Hydrophone should be positioned using aft stays (C2), and secured using forward stays (S1 or S2).
C. Clump weight (C2 and S2)
Clump weight (~300 lbs) deployed with CTD winch off port side 5m below the surface.
Tighten clamps on clump weight cable and secure one line to the cable, one line to the tether, and clip cable and tether together.
Lower clump weight until desired depth is reached (10m above the bottom, 15m in high relief areas), securing the cable to the tether every 5m.
Last umbilical tag is secured to cable in a triangular fashion when clump is 10-15m off the bottom.
S1 assigns tasks to S2, S3, S4 and S5
ROV deployed using main crane off port side. (Note: vessel should always be positioned so port side deployment of ROV is done on the windward side. This prevents the vessel from being blown down onto ROV or its umbilical).
Alert bridge that ROV is in the water (C2).
ROV will run out to the port side of vessel, between the bow and the clump weight to its working radius (~30-40m; S3).
ROV umbilical attached to the clump weight cable (~ 5m above weight), and tether held taught.
ROV and clump weight lowered simultaneously with depths of both ROV and weight called out to both the CTD winch operator and the ROV pilot.
ROV pilot surveys the bottom while staff monitor sea floor depth (S3), ROV depth (S3), position of the vessel (S3), and the clump weight depth (C1, C2, S1, S2, S3, S4).
E. General notes
Launch should not be started until bridge has alerted deck and lab that screws are disengaged. Depending on conditions it may be necessary to position the boat at a given distance from the target site.
Appendix VII- ROV Recovery
S1- Reelperson, deck communications
S2- sling/wire tender
S3- ROV pilot
S4- Recorder, lab communications
C1- crane operator
C2- clump weight tender/bosun
S1 assigns personel to S2, S3 and S4
1. Lab alerts deck and bridge that recovery is desired (S4).
ROV pilot (S3) tilts the cameras down and turns off the lasers and lights.
Captain will position surface vessel for recovery, with wind on port side, and advise the lab when recovery can begin.
ROV will run out to vessels port side to a length that will allow it to surface in a safe manner (S3).
Clump weight will be raised simultaneously with ROV, ~5m at a time in order to allow ROV team to detach umbilical from the cable (S2, C1, and C2).
Deck crew (S2) will alert pilot when ROV is visible from the surface so pilot can position his/herself on the deck for surface driving.
Once the final tag has been detached, clump weight will be brought aboard (S2, C1, and C2).
ROV will then be recovered using the main crane and a recovery hook and lanyard ((S1, S2, S3, C1, and C2).
Once ROV has been recovered the hydrophone stays can be released and hydrophone will then be raised and secured (see Appendix V, section B).

1. Configure- Data Events- Setup- change to ‘Manual Start’- save with appropriate filename
2. File- Edit working files- choose Logs- enter appropriate filename
Appendix X- NOAA Corps and Scientist operation briefing
The lab places a cross on the WinFrog display at the point where the transect is to start.
The bridge is to advise the lab when the ship is ready - 15 minutes of drift time away from the transect start (10 minutes for ROV deployment, plus 5 minutes for the ROV to dive to operating depth).
One scientist, who is also the observer on the ROV console, sends and receives all lab communication between the bridge and the deck.
The bridge navigates the ship so the wind is on the port side for deployment.
The ideal speed of the boat over the ground for ROV transects is between 0.3-05 knots
If the end of the tether is reached, from the clump weight, then the ROV begins to be towed by the boat and control is lost.
The lab is to keep the WinFrog display on-line during deployment to assist the bridge in navigation and drift prediction. At all other times, unless necessary, the display should also be available to the helm for naviagtion.
Abort the ROV launch if ROV cannot dive to the bottom and stay with the ship at the same time (usually when the drift is greater than 1-knot).
The bridge is to advise the lab when the speed and direction of the ship needs to changed to maintain transect depth or ship safety.
The command “De-clutch” is to be used to stop propellers if the tether is in immediate danger of fouling the props.
