CSE’s Coast Guard certified captain, Drew Giles, pilots the RV Southern Echo for offshore data collection. RV Southern Echo is a 24 foot Tuff Boat Great White with a custom welded aluminum hull with twin 90 Honda outboards. A fully enclosed cabin and spacious working deck allow our crew to survey, deploy gauges, and collect samples in a comfortable and controlled manner.
CSE’s field data collection, equipment, and in-house capabilities focus on three critical aspects of coastal engineering:
- Measurement of coastal processes and sediment transport.
- Measurement of topography and bathymetry.
- Measurement of sediment quality.
Among CSE’s high-end instrumentation are:
- RDI acoustic current meter (Workhorse ADCP).
- Sontek acoustic current meters (XR).
- Two CL wave gauges with paros sensors.
- Four CL tide gauges with paros sensors.
- One CTD profiler.
- Trimble® Model R8 GNSS RTK-GPS survey equipment.
- Integrated Trimble® Odom CV100 real time GPS bathymetry mapping system.
- Proprietary coring system operated by divers for borrow area sand searches.
In one project, CSE’s in-house staff (including certified diver-engineers) deployed nine instru-ments for 30 days, retrieved them, downloaded the data, and then redeployed them at new locations for another month before retrieving the gauges. Despite zero visibility in the turbid waters of the site, CSE’s technicians were able to recover all gauges, and only 5 percent of the data were lost because of equipment malfunction.
