EdgeTech Introduces Two New 3400-OTS Lightweight Pole Mount Sub-Bottom Profiling Systems
EdgeTech, the leader in high resolution sonar imaging systems and underwater technology, has recently introduced two new Pole Mount Sub-Bottom Profilers to the family of 3400 Sub-Bottom Profiling Systems.
Building on the long running success of the EdgeTech sub-bottom profiler product line, the new Ultra-Lightweight Shallow Water and Lightweight Shallow Water over-the-side pole mount 3400-OTS systems provide users many unique enhancements to current sub-bottom profiler systems. The 3400-OTS transmits wide band Frequency Modulated (FM) pulses utilizing EdgeTech’s proprietary Full Spectrum CHIRP technology. The systems use flat multi-channel hydrophone arrays to generate high resolution images of the sub-bottom stratigraphy in oceans, lakes, and rivers and provides excellent penetration in various bottom types. The 3400-OTS receiver array is segmented for standard sub-bottom profiling operations or “pipeline” mode for optimal location and imaging of buried pipelines or cables. The system offers real-time reflection coefficient measurements. This unique function of the EdgeTech sub-bottom profiler system allows users the ability to collect complex ‘analytic’ data using linear system architecture to measure sediment reflection and analyze sediment type determination. Additionally, the system has discrete transmit and receive channels allowing for continuous data collection resulting in a high ping rate particularly important for construction and pipeline surveys.
The lightweight 3400-OTS systems are ideal for shallow water surveys using small boats of
opportunity. The sub-bottom profiling systems come as a complete package including EdgeTech’s DISCOVER sub-bottom acquisition & processing software. The 3400-OTS can also be interfaced to 3rd party software.

New camera technology brings huge savings and hugely improved performance
A new combined Stills-Laser-Video camera is taking the marine science market by storm.
C-tecnics have used new technology to bring huge savings for customers looking for a camera offering multi-functions required in aquatic and benthic studies. The system offers real time video and stills photography with built in lasers for scaling marine creatures.
The SLV Mk 2 camera minimises use of wiring and separate components to reduce costs in production and assembly and is significantly less than any competing system. The design results in an exceptionally robust product with up to date video processing technology.
Once the deployment has finished, all video recording and still images can be easily downloaded via a USB connector. Controls are through RS232/RS485 connection via software.
A major Scientific institute has recently exchanged older systems for the new product and are delighted with the increased performance and high quality images.
Teledyne CARIS announces its complete workflow software, Onboard360, featuring data acquisition with CARIS Collect
Teledyne CARIS partnered with Teledyne Marine to leverage years of leadership in the marine survey market to create CARIS Collect, a modern and easy to use software package for data acquisition.
Teledyne CARIS, a Teledyne Technologies [NYSE:TDY] company, and leading developer of marine mapping software, is pleased to announce the release of Onboard360 featuring CARIS Collect. The newly released software delivers a seamless flow of data into the Ping-to-ChartTM workflow. When combined with the Onboard360 Process module, logged data is imported and processed automatically allowing near real-time and remote quality monitoring of in-progress surveys.
The CARIS Collect module provides simple and effective data collection for the most common sonar and lidar systems in the market. CARIS Collect was designed with an intuitive user experience for ease of integration and simple user adaptation, minimizing the effort required to implement new software.
Vice-President of Sales and Marketing Andy Hoggarth commented: “We are pleased to offer our customers the ability to collect with confidence using CARIS Onboard360. Our Ping-to-Chart solution is now complete with the inclusion of the simplest acquisition software available for hydrographic survey operations whilst providing significant reductions in ship to shore turnaround times.”
Available as a perpetual or SaaS annual license, Teledyne CARIS has made Onboard360 the most cost-effective acquisition software package on the market.
Teledyne CARIS is hosting a webinar on Thursday, March 25, 2021 at 10:00 a.m. EDT to expand on key features and benefits of Onboard360 and the CARIS Collect module. Interested parties can register here:

Sequoia launches a new high-precision transmissometer for underwater vehicles
Sequoia announces the LISST-Tau – a new, compact, 2,000-m rated high-precision transmissometer for underwater vehicles, profiling packages, CTDs, remotely operated towed vehicles and other underwater systems. The LISST-Tau is available with a green or red light source and uses a 15-cm pathlength for high-precision measurements across a wide range of water types. More information and data sheet for the LISST-Tau is available here: www.sequoiasci.com/product/lisst-tau/
Dr. Ole Mikkelsen, Sequoia’s President, says about the new development ‘We are delighted that we are able to bring a high precision transmissometer to market. Our particle-sizing LISSTs, on the market since 1995, have always been able to measure transmission but the LISST-Tau is our first dedicated transmissometer. It has been field-tested and performs very well in challenging waters and at depth.’
The LISST-Tau is available through Sequoia and Sequoia’s worldwide distributor network (www.sequoiasci.com) for all commercial and scientific applications. The LISST-Tau is available for immediate ordering with a six-week lead time. Sequoia expects the LISST-Tau to be available from stock by Q4 2021.
Kongsberg Maritime launches new cNODE MiniS transponder with pressure sensor
Kongsberg Maritime is pleased to announce that it has augmented its range of cNODE MiniS SSBL (Super Short Base Line) and LBL (Long Base Line) transponders with new models incorporating an internal, high-accuracy strain gauge pressure sensor.
The new transponder units are designed primarily for positioning ROVs, AUVs and towed bodies, and are also well adapted for operations where additional depth data or depth aiding is required, such as when locating subsea structures. This makes them particularly useful for windfarm installation support applications.
A range of models with different pressure sensors are available to maximise the accuracy of the reading. The 100m-rated unit would be best suited for windfarm installation, while the 1,000m- and 4,000m-rated units are ideal for use in contexts such as subsea construction, deep-water research, towfish tracking and AUV missions.
Pressure sensor data can be simultaneously reported on the back of the SSBL navigation reply pulse with no requirement for additional telemetry. The new transponder shares its specification with standard MiniS models and is fully compatible with HiPAP, µPAP and cPAP medium-frequency underwater positioning systems, using KONGSBERG’s Cymbal wideband acoustic protocol and FSK (Frequency-Shift Keyed) signalling. Configuration is carried out via an RS-232 connection or acoustic telemetry.
“Our cNODE MiniS transponders have attained a very solid reputation for the enhancements in accuracy and operational safety they have helped to establish in a broad variety of important functions,” says Erik Bjerke, cNode Product Line Manager, Kongsberg Maritime, “and the new units are destined to bring that same vital level of detail and reliability to an even wider range of applications.”
