DeepWater Buoyancy’s Pop-Up Buoy Recovery System (PUB) allows for direct retrieval of seabed packages, such as anchors, anchor lines, and bottom-mounted frames and instruments. Easily mounted to any framework, the assembly sits on the seafloor until the acoustic release is activated. Once the release completes its disconnection, the buoy sub-assembly lifts free from the canister sub-assembly and rises to the surface. A synthetic line connects the buoy directly to the framework of the seabed item and allows for retrieval.
The buoy sub-assembly is configured with a syntactic flotation collar, an electro-polished 316 stainless steel frame, and 75 meters of 1/4″ synthetic line. (Other line lengths are available upon request.) The recovery buoy is made from high-strength DeepTec® solid syntactic foam that is rated to 500 meters of depth. The foam is finished with an abrasion-resistant, polyurethane elastomer coating.
The canister subassembly is made from PVC and 316SS plate. It has a rugged design and has attachment features to permit various mounting configurations, including easy mounting to our BTM-AL50 tripod bottom mounts. The standard recovery system is designed to work with both the legacy Teledyne Benthos 875 shallow water release, as well as the new R500 series release.

AML Oceanographic UV Biofouling Control
When instrumentation is deployed underwater in a stationary position for long periods of time, biofouling will occur. This unwanted marine growth causes sensor drift, requiring preventative measures to ensure accurate data.
