The Warm Springs Dam on Dry Creek, near Healdsburg, California provides much needed water storage for residents of Sonoma and outlying counties in Northern California. In 2008, the National Marine Fisheries Service (NMFS) determined that the 13 mile long tributary to the Russian River was lacking sufficient habitat diversity to support natural spawning and rearing for endangered CohoSalmon and Steelhead Trout.
HyDrone-RCV: Integrated with SonTek’s M9 ADCP for Surveying a Glacier
Written by Carol Cartier
El Dorado Hills, California, September 14, 2015 – Seafloor Systems is pleased to announce the collaboration with SonTek/Xylem for integration of the HyDrone-RCV with a SonTek® M9 ADCP (acoustic Doppler current profiler).
Two integrated HyDrone catamaran platform systems were shipped last week to IMAX videographer Sean Casey, who will return to Alaska for a month-long filming of Dawes glacier. Casey is producing an IMAX documentary for National Geographic called “Extreme Weather”. One of the film’s main sequence follows a glaciologist to Alaska where she and her team collect data on: the amount of ice and water that is being ejected from a glacier; track the speed of which it is melting; and determine how much water the glacier is adding to the ocean.
The HyDrone–RCV system—released in June 2014—is a remotely controlled multi-purpose vessel that was designed to survey in uncertain environmental conditions and may be specified to individual customer requirements. The unit may be purchased with the desired depth sounder pre-installed, as an integrated total solution, or supplied ready to accept existing equipment from the user's survey pool.
