Teledyne Reson SeaBat T50

Land & Sea Surveying remains at the forefront of surveying technology. The latest and greatest of our technology is the Teledyne Reson Seabat T50. The Seabat T50 is designed for shallow water surveys.  Combined with the Portable Sonar Processor, the SeaBat T50 provides unprecedented survey data, providing faster operational surveys and reduced processing time. The T50 is designed for fast mobilization on smaller vessels. This equipment is fully frequency agile from 190 to 420 kHz, allowing for improved swath performance and reduced survey time under challenging conditions. It is capable of bathymetry, snippets, side-scan and water column backscatter, compressed water column, normalized backscatter; 7K data format; Gbit Ethernet. 

Here are some examples of Reson SeaBat T50  collected data in Lhoist Lowell Quarry.

These are from Cocoa Grand Borrow Pit; bottom left shows an old sunken crane at the bottom of the pit.

EdgeTech  Full Spectrum SB-216S, 3100 Portable Sub-Bottom Profiler

The EdgeTech Sub-bottom Profiling System is a wideband Frequency Modulated (FM) sub-bottom profiler utilizing Edge Tech's  Full Spectrum CHIRP technology. The system generates high-resolution images of the sub-bottom stratigraphy in oceans, lakes, and rivers. Sub-bottom profiling systems are used to determine physical properties of the sea floor and to image and characterise geological information below the sea floor. 

Just above are Sub-Bottom Profile reports.

Edgetech 4125 Side Scan Sonar 

EdgeTech’s 4125 Side Scan Sonar System was designed with both the Search & Recovery (SAR) and shallow water survey needs in mind. The 4125 utilizes EdgeTech’s Full Spectrum CHIRP technology, which provides higher resolution imagery at ranges up to 50% greater than non CHIRP systems operating at the same frequency. This translates into more accurate results and faster surveys, thus cutting down on costs.  The 600/1600 kHz set is ideally suited for ultra high resolution imagery in order to detect very small targets (SAR).

Ultra high resolution imagery for easier identification of targets
Lightweight for one person deployment
Dual simultaneous frequencies
600/1600 kHz towfish

Gladius Mini Underwater ROV Drone

The new ROV mini drone is small, compact and is utilized for underwater surveying.  This underwater drone can dive to 330 feet. It is equipped with a camera that can capture UHD 4K and Full HD video, and it can also capture 12-megapixel stills. On both sides of the camera are adjustable 1200-lumen LED headlights with a continuous-power dial on the controller. The battery and 64GB SDXC card are sealed in the vehicle. We attach a smart phone or tablet to the remote control, and the base station creates a Wi-Fi signal that allows the remote control to position the vehicle in the water which allows us to see what the camera is seeing on the smart phone or tablet with the specified app. 

Two Specialty Devices Singlebeam Hydrographic Survey Systems:

Intelligent Depth Sounder that digitizes the echo to 16 bit resolution and stores the full digital record on hard disk 
Sounding ranges to 200 meters with accuracy to one centimeter 
DepthPro Software and Depthpic Software provide convenient replay and reprocessing of hydrographic data.

SonTek CastAway-CTD

The CastAway-CTD is a small, rugged and technically advanced CTD designed for profiling to depths of up to 100m.This  system incorporates modern technical features which allow it to achieve a 5 Hz response time, fine spatial resolution and high accuracy. It uses a six electrode flow-through conductivity cell with zero external field coupled with a rapid response thermistor to attain high measurement accuracies.  Each CastAway-CTD cast is referenced with both time and location using its built-in GPS receiver. Latitude and longitude are acquired both before and after each profile. Plots of conductivity, temperature, salinity and sound speed versus depth can be viewed immediately on the CastAway's integrated color LCD screen in the field.

Vibracore 

Vibracoring is a sediment sampling technology to obtain undisturbed cores of sediment in saturated or nearly saturated conditions by driving sampling tubes with a high-frequency-low-amplitude vibrating device. During sediment coring, the high-frequency vibration transfers the energy to the sediment and aids in the liquefaction of the surrounding sediment.

Specifications:

High frequency vibration acquires near undisturbed cores
Ideal sampler for sediment geophysical parameters, contaminants, and trace metals
Unique near zero “core compression” for accurate true depth of sample recovery
30 foot long core samples from up to 350 foot water depths
Designed for small boat operation. Powered by two 12 volt batteries
Core Keepers in Stainless Steel or Aluminum available for very soft or coarse sand sediments
Integral “floating” top vent and seal helps collect very soft sediment samples
Unique, power saving “Energy Storage” weight ring design increases effectiveness
Quick-change and long-life core tube mount makes core tube mounting a simple operation
Simple, safe low-voltage car battery power, no generator or compressor needed on a small boat

Here is a sample Vibracore Report shown below...
