Bottom
tripods for oceanographic and hydrologic instruments
The
Sea Spider is an inexpensive, trouble-free tripod
for your seafloor instrument packages. It is designed
for deployment of ADCPs, ADPs, transponders, pressure
sensors, wave gauges, CTDs and virtually any other
type of oceanographic instrumentation package.
The Sea Spider can carry multiple instruments
and a popup buoy for diverless recovery.
Gimbals are available for deployment on unlevel
seafloors.
The Sea Spider platform is
built around a thick fiberglass casting that's
designed for long-term immersion in seawater at
any depth. It has lead ballast feet and corrosion-free
plastic instrument clamps. All fasteners are 316
stainless steel.
The standard Sea Spider weighs
45 lbs without lead ballast. A modular option
allows the assembly to be shipped in a box rather
than on a pallet. See the photo of a disassembled
modular Spider at right.
