Overview
The Ocean Sonics Recorder Buoy is an easy way to deploy one or more icListen Smart
Hydrophones while keeping them synchronized. The yellow drifting buoy is small and
lightweight, so it can be deployed from a small vessel. This solution combines power, data
storage, and time synchronization with a hydrophone array.
Create a custom array using the extension cables and Smart Cables as building blocks.
Setup and configure the hydrophones with the help of the Gordon Application to provide full
time sampling or sample periodically using the duty cycling feature.
Record data on the hydrophones or on a hard drive within the buoy increasing data storage
to 2 TB.
Important Notes
•Store the buoy upright or laying on side.
•Do NOT flip the buoy or turn upside down.
oBattery positioning is ballasted for upright position.
oTurning the buoy upside down could result in damage to batteries.

Ocean Sonics Buoy Quick Start
OSL Tip:
For a quick setup install Ocean Sonics’ Software Programs
Gordon, Marco &Lucy on your PC prior to setting up your buoy.
Assemble Buoy Configuration
1. Ensure the buoy has batteries properly loaded and is in the OFF position
(OFF Position: 0).
2. Attach cables, smart cables and hydrophones in configuration for deployment
(See Appendix A).
3. Turn ON Ocean Sonics Recorder Buoy (ON Position: 1).
Connect to Recorder Buoy
4. Attach the serial cable to the top of the buoy in the designated MCBH8 connector.
5. Connect the cable (USB end) into a computer USB port.
a. If the USB device is not recognized when the test cable is plugged in, run the
setup executable installation package for the driver that can be found on your
data stick (/icListen/Serial to USB Test Cable Driver).

Setup Sampling on Recorder Buoy for Deployment
6. Open the Gordon application on your PC.
7. Choose Connect to a Smart Recorder .
8. Choose your device from the list.
a. Click on the Battery Pack.
b. Click Connect.
9. A page will be displayed with the Battery Pack Status.
a. Click Set Time.
This will set the time to be the same
as your computer. This is important
to avoid unwanted recording and for
all your data to have the proper date
and time.
b. Click Data Settings.
10. Add your hydrophone:
a. Click on the [+] button to add a channel (hydrophone).
b. Type in the serial number of the icListen hydrophone(s) connected to the
Battery Pack.

c. Choose the settings for the Waveform Data, Spectrum Data, Delay and Smart
Recorder Settings.
d. A Start Delay is useful to start the duty cycle at a designated time
(if no delay is chosen, the recording will begin at the start of the next minute
after clicking Apply).
e. Click Apply Settings ‘Click Here to Apply These Settings to Battery Pack #_’.
The Apply Button will disappear to show that settings have been applied successfully.
For more information on Gordon Application and setup see Smart Recorder User Guide on
USB stick under Gordon Folder.

Deployment
1. Set-up Recorder Buoy for deployment (See Appendix A.).
2. Vessel should be stopped while lowering equipment over side of vessel.
3. Start deployment with bottom of array cables.
a. Lower weight on end of cables into water.
b. Slowly feed in the hydrophones and cables of the array.
Special care should be taken with heave plates and hydrophones.
c. The Buoy will be the last instrument lowered to the water.
Recovery
1. Transit to buoy.
2. Use gaff hook to secure buoy.
3. Tie a rope to the top ring of the buoy to secure while recovering.
4. Retrieve the buoy from the water.
a. Place the buoy on deck while holding onto rope attached to cabled array
below. [Winch can be used to allow easier retrieval of buoy on deck.]
b. Slowly pull out heave plate and recover remaining array by hand, with special
care handling hydrophones.
5. Turn off buoy (OFF Position: 0).
6. Hydrophones can be Powered Down to retain battery at 100%.
For each hydrophone: Attach the test cable to the hydrophone. Insert and then remove
the hardware reset tool (9V battery) plug into the barrel connector of the test cable.
7. Rinse the buoy and equipment with fresh water.
Hard Drive Retrieval
1. Recover the Buoy (see above).
2. Dry the buoy fully.
3. In a dry environment ensure all hardware is clean and dry.
Special care should be paid to moving parts and crevasses.
4. Ensure buoy is in OFF Position: 0.
5. Unscrew the eye nuts on the top of the buoy to remove the top hat.
6. Gently pull up the top hat without pulling on the cables within the buoy.
a. The top of the buoy will only be opened momentarily, and cables should remain
attached while retrieving the hard drive.
7. Remove the hard drive by unscrewing the 2 thumbscrews securing the drive.
Before Deployment:
It is suggested that users secure top hat of buoy before deployment. This can be done with
a vinyl coated steel cable and pad lock. Thread the cable through the eye nuts and padlock
to secure in place. This will ensure the eye nuts will not become loose and it will prevent
opening of the top hat until retrieved.

a. Slide out the hard drive along the metal base as a guide.
b. DO NOT pull up on the hard drive as it could damage the connector.
8. Replace top hat of buoy back into place until the hard drive is returned.
9. Use a SATA cable to plug the hard drive into a USB port of a computer.
10. Retrieve the data on the hard drive and remove data for next deployment.
11. After the data transfer, return the drive.
a. If you are replacing the drive with a new drive, ensure the correct formatting
has been applied to the drive (exFAT with MBR partitioning).
Battery Replacement
1. Ensure Buoy is OFF (Position: 0).
2. Unscrew eye nuts and remove top hat.
3. Remove batteries.
a. Disconnect all cables from the top hat of the buoy.
b. Remove batteries carefully from the buoy.

4. Line up new batteries to insert in same fashion batteries were removed.
5. Pull cables through the middle of the batteries.
6. Attach cables to connectors as shown above.
Note: Batteries can plug into either of the top hat connectors.
Maintenance
•The Recorder Buoy should be thoroughly rinsed with fresh water after each
deployment to remove saltwater and debris.
•The Recorder Buoy should only be opened when it is safe to do so in a clean
environment without chance of water entering the inside.
•The Recorder Buoy and hydrophones should be shut down when not in use to
conserve battery.
