Personnel of the firm have surveyed hundreds of miles of inland waterways throughout the State of Florida including many coastal regions of the United States, South America, Caribbean, Puerto Rico and the U.S. Virgin Islands. Hydrographic and remote sensing studies are conducted from one of SDI’s fleet of multiple vessels of varying size, type and capabilities. Typical inland and nearshore hydrographic surveys are conducted using a 25-foot survey launch with enclosed cabin and center-hull mounted transducer or 17-foot center console survey launch. These vessels have trailers for efficient mobilization to any location in Florida. For deep water surveys or survey operations requiring accommodations and / or long travel, SDI has a 35-foot launch with enclosed air-conditioned cabin, generator, dive compressor, kitchen, head / shower and sleeping accommodations. This vessel also has a trailer for efficient mobilization to any location within Florida. For extreme shallow water operations, SDI has numerous survey skiffs ranging in size for 12 feet to 19 feet. For sediment testing, including vibra-coring and dive operations, SDI has a 26-foot survey platform with open deck and A-frame. Bathymetric data is collected using Odom single or dual frequency sounder and where deemed necessary this system may be interfaced with a DMS-05 Motion Sensor System. Sounders equipped with multi-beam technology may also be employed as necessary for the project. For horizontal vessel positioning, a Trimble-based real-time Differential Global Positioning Systems (DGPS) is utilized with vessel navigation and data collection/storage provided via the Coastal Oceanographics’ “Hypack” system. “Hypack” is a powerful software used for pre-planning survey transects, vessel navigation, bathymetric data collection and data processing. The system applies horizontal position to sounding data real-time during the course of the survey, allowing review of bathymetric data during the course of collection to ensure quality of data. The software provides an efficient tool for data processi ng, charting and volume computations. Side Scan Sonar Technicians at SDI are also experienced in the field of side scan sonar surveying for efficient mapping of exposed bottom features that may be pertinent to a design or construction project. Side scan sonar will produce an acoustic image of the bottom from a digital tow fish operating at high frequency ranges of generally 400 – 900 kHz. The survey is conducted using an ultra-high resolution (400 / 900 kHz) side scan sonar system that utilizes full spectrum CHIRP technology. Georeferenced acoustic images are collected digitally real -time and translated to digital mosaics in a .tiff format. The system is cable of detecting and mapping exposed bottom features such as exposed rock, vegetation cover, pipeline / cable crossings and manmade debris. This system also enables the rapid location of hazardous debris that might impede navigation in the wake of a storm event. Inlets and harbors are a valuable resource for the supply chain and need to be cleared quickly, efficiently, and positively.
