Sea Floor Platforms Sea Spider Barnacle The Dependable Choice For Seafloor Deployments Oceanscience seafloor platforms are selected when a deployment system has to last. High quality materials and construction designed for long-term immersion in seawater ensure a package that will stand the test of time. Acoustic profiler mounts for most common instruments are available as standard. Custom mounts can be designed and added to each of the platforms for many other sensor types and deployment requirements. Sea Spider - Tripod The Oceanscience Sea Spider is used by major oceanographic institutions across the world. It is designed for deployment of ADCPs, transponders, cameras, pressure sensors, wave gauges, CTDs and virtually any other type of compact oceanographic instrumentation package. The Sea Spider can carry multiple instruments and a pop-up buoy for diverless recovery. Gimbals are available for deployment on uneven sea floors. The Sea Spider has lead ballast feet and corrosion-free plastic clamps to protect your instruments. A modular version is available to allow the Sea Spider to be shipped in a box rather than on a pallet. Barnacle 53 - Trawl Resistant Frame The Oceanscience Barnacle 53 is for deployment in areas where trawling is a problem. The Barnacle’s low profile and curved edges minimize the potential for disturbance. The Barnacle provides the strongest protection available for your Doppler profiler or other sensors. There are no corners or edges to snag. Externally inserted lead ballast makes the Barnacle easy to handle on deck and easy to deploy from any size boat. The optional canister gimbal insert houses the gimbaled instrument so that the entire assembly may be easily removed by a diver.
