Pole Buoy
Pole Buoy
The purpose of the pole buoy is to help track, find, and support the drifting recorder. The pole buoy consists of;
- Aluminum Pole: 9’ length, 1.25” 6063 aluminum round tube
- Lead Weight: approximately 17 lbs, attached to the bottom of the pole to keep buoy vertical
- Crab Floats: to keep pole buoy floating, with bolts above and below it to keep it from sliding along the pole
- Bridle: 12 strand line that links the pole buoy to the rest of the drifting recorder setup and arrray
- Radar reflector: so ships can see the pole buoy
- GPS mount: to hold the solar GPS and strobe light
Pole Buoy Assembly
Prepare the bridle:
There should be 3 pieces of clear abrasion resistant hose along with the 12-strand thick blue/green line in the tote
The bridle will have 3 loops in it: two go around the pole (1 loop below the crab floats, 1 loop above the crab floats) and one loop is in the middle to attach to the rest of the gear
These loops get a BIG workout– put the hose on the line at each of these loops to minimize abrasion of the line during deployment
Put lower loop of bridle onto the pole
Add crab floats:
Put 2 orange crab floats onto the pole so that the flat ends of the crab floats butt up against each other
There are bolts that go through the pole at the top and bottom of the floats to help keep them in place
We have also been putting a hose clamp between the buoys & the bolts, and then wrapping this in electrical tape
Radar reflector and GPS mount:
At the top are the radar reflector and the GPS mount
The radar reflector goes over the pole, and then the GPS mount is inserted into the top of the pole
A bolt (currently attached to the GPS mount) holds both in place
The pole, reflectors, and GPS mounts are labeled A, B, C to identify sets that fit well together previously
Strobe Light- Prior to deployment, add batteries & zip tie the strobe onto the GPS mount
Add reflector tape to the pole below the radar reflector
Note: We are still working on improving this design– all suggestions are welcome!
