HydroSurveyor, San Diego


rQPOD Remote Boat Surveying Package

INTEGRATED WITH HYPACK® The HydroSurveyor is a system designed to collect bathymetric, water column velocity profile, and acoustic bottom tracking data as part of a hydrographic survey.  The two key components of the system are the HydroSurveyor Acoustic Doppler Profiler (ADP®) platform, and the powerful, yet user-friendly, data collection software. With the HydroSurveyor platform, SonTek is able to offer an exclusive 5-beam depth sounding device, with built-in navigation, full water column velocity (currents) profiling, full compensation for speed of sound (with the CastAway-CTD), and an integrated positioning solution.

Flexible and Fast.

Water sound speed corrections are interpolated in both space and time with the fully integrated CastAway-CTD.

All Inclusive.

Full water column velocity mapping, 5-beam depth sounding and acoustic bottom tracking (for speed over ground when GPS is lost) provide comprehensive data for a complete solution with a single package.

Software Centric.

With built-in automatic data gridding and interpolation, even intricate surveys will not require specialized complex software, saving you time and money.

The Hunt for Sumerged Steams

The Hunt for Submerged Streams

Hydrologists and water monitoring specialists at the St. Johns River Water Management District are on the hunt to find submerged springs along the bottom of the Saint Johns River and to understand the springs' input to the river system when the river level is at different stages. After discovering that their M9 could also function as a more effective tool for bathymetric mapping and velocity field mapping, they decided to upgrade the M9 to a HydroSurveyor. With data from both modes, they could create river flow models to find those submerged streams - and what they found open the teams eyes!
