SeaBat T-Series normalized backscatter demo

Fri, 16 Jun 2023 11:20:47 GMT

Ever had to do a multibeam survey but told not to change the sonar settings because it ‘messes’ up the backscatter? Let’s make things simpler. Normalized Backscatter corrects for sonar settings in real-time so that you collect good bathymetry and good backscatter.

SeaBat T-Series v2.0 update. Introduction and demo

Fri, 27 Nov 2020 10:28:11 GMT

SeaBat is the world’s leading sonar brand in seabed mapping.

A SeaBat sonar is specifically designed to provide the best performance possible. It is designed to solve the task as quickly, effortlessly, efficiently, accurately and as user friendly as possible.

Measuring a distance may sound easy, but transmitting mechanical wave fronts (sound) from a non-stationary platform (boat), into a dynamic and highly absorbent medium (water) and very accurately detecting and analyzing extremely weak sound signals that return, in real-time, is an incredible engineering challenge that only very few companies master – and a SeaBat sonar does this up to several millions times per minute.

TM Academic Grant Winner - Christian Armstrong - Teledyne RESON SeaBat T50-R...

Thu, 30 Jul 2020 17:20:00 GMT

Scottish Association for Marine Science (SAMS).

Product grant: Teledyne RESON SeaBat T50-R Multibeam Sonar / INS

The project's aim is to assess the physical stability of the seafloor in the extremely energetic tidal flows of western Scotland, UK: The Gulf of Corryvreckan and the Falls of Lora, Loch Etive.

The nature of the seabed beneath extreme tidal flows (flow speed > 4m/s) has been little studied, mainly due to the obvious operational challenges posed by the area's hydrodynamics. However, these regions are now receiving research attention due to their value for renewable energy and the insights into turbulent flows that they can bring.

As a student researcher, I am working with a team from the Scottish Association for Marine Science (SAMS) on plans to develop survey techniques for mobile bedform analysis. By comparing two bathymetric data sets (one collected in 2012, and one using Teledyne equipment scheduled for 2020), bedform migration rates and thence the physical stability of the seabed can be quantified.

Combined Laser/Multibeam Sonar Survey of Sydney Harbor

Fri, 06 May 2016 10:34:02 GMT

By Dario Conforti - Teledyne Optech

Combined Laser/Multibeam Sonar Survey of Sydney Harbor

Teledyne Optech has been a world leader in the design, development and manufacture of advanced lidar instruments for 40 years. In the last few years Teledyne Optech and its sister company Teledyne RESON developed a full and seamless integration between their sensors, the motion-compensated ILRIS-3D laser scanner and the SeaBat 7125 Sonar System, through the PDS 2000 software. The ILRIS Motion Compensation (MC) option was developed to let surveyors use the normally static ILRIS dynamically by combining it with a Position and Orientation System (POS) and Global Positioning System (GPS) receivers. The resulting system is integrated into a mobile mapping system and enables much more effective mapping in wide and complex terrain. This type of mobile laser scanning is now at the cutting edge of coastal survey technology because it allows surveyors to easily survey coastlines directly from a boat and is particularly useful for mapping long or inaccessible coastal areas. This presentation will explain the integration of the ILRIS and SeaBat sensors and showcase several applications in the last few years from Europe to North America to Australia. The survey in Sydney, Australia is the most recent survey made and shows the perfect match between the underwater data from the sonar and the shore data collected from the lidar scanner.

The history of the SeaBat Sonar

Wed, 02 Dec 2015 09:47:04 GMT

Uni Bull, Senior Product Manager at Teledyne RESON, guides you through the evolution of the SeaBat sonars, starting with the first commercial forward looking sonars from the early 90′s to the newly released SeaBat T-series multibeam echosounders.

Uni Bull describes the sonar evolution like this:
“The early sonars were good then, a bit like the commodore 64 computers, but compared to the technology of today, they have a hard time.”

The benefits of online analysis of sound speed profiles during data acquisition

Mon, 06 Jan 2014 15:35:04 GMT

By Hydrographic surveyor - Morten Sølvsteen, Danish Geodata Agency

Presentation outline

The two major uses of the ”skeleton”

1) Line planning
Line planning for more efficient surveys.

2) On-line analysis of sound speed profiles during data acquisition
A method for analyzing overlapping areas in multibeam echosounder surveys is introduced. The method requires that the velocity of sound at the transducer is monitored during the survey.

The method applies the principle of least squares to determine the vertical offset and the bias of the swaths caused by insufficient knowledge of the velocity of sound in the water column below the transducer.

This presentation was given at the Teledyne RESON Underwater Technology Seminar in Copenhagen 2013.

Herring-eating killer whales see with a SeaBat 7128

Mon, 02 Dec 2013 11:27:37 GMT

Icelandic killer wales: the case of herring-eating killer whales

Killer whales, as top predators can have important impacts on marine food webs, but understanding these impacts, particularly in the face of changing environmental conditions requires an understanding of the adaptability of their feeding behavior. Icelandic killer whales are thought to feed predominantly on herring, a fish that dramatically changes its behavior throughout the year, depending on whether it is spawning, in the summer, or overwintering, in the winter. The aim of this project is to study if and how the feeding behavior of Icelandic killer whales changes at different times of the year to adapt to their prey behavior.

Video paper: Pipeline surveying from a surface vessel in the Caspian sea

Mon, 25 Nov 2013 12:49:39 GMT

Surface Vessel Based Multibeam Pipeline Inspection

In a special collaboration between BP, Fugro Caspian and Teledyne RESON an unconventional approach was used to survey pipelines in the Caspian Sea. A vessel was outfitted with two pole mounts each equipped with a SeaBat 7125 SV2 using FP3. Teledyne PDS software was used to automatically detect and track the pipes in real time. A total of 710 km pipe was surveyed in just seven days. This presentation outlines the advanced technologies that were involved to collect such high resolution pipeline data.

Surveying in the most remote place in the world, Antarctica

Fri, 01 Nov 2013 14:41:45 GMT

Navigation data is poorly available in Antarctica. If navigational data is available it often dates back to the early 1900s with many lead line surveys. An initiative was undertaken by Stephen Wilkins of Xplore Expeditions to collect bathymetry with a multibeam SeaBat 7125-SV2 survey system making use of the sailing vessel Xplore. Together with Yoann Boulaire from SHOM, France and Fernando Landeta, hydrographic technician from Skyring Marine Chile, an IHO qualified survey was performed in Antarctica on an expedition sailing yacht.
