NORBIT Multibeam System for Emma Rentals

Peter Eriksen of NORBIT delivered a NORBIT iWBMS system for Emma Rentals during Oceanology International 2016. The iWBMS is the tightest-integrated high-end multibeam echosounder with built-in GNSS/INS. Several jobs have already been contracted by Emma Rentals, both for inland waterways and off the Baltic coast. The NORBIT iWBMS system including the Applanix Wavemaster 2 OEM GNSS/INS will also serve as an important asset for Emma Technologies' research activities within the field of advanced backscatter processing. Emma Technologies, a manufacturer of  ASVs/ USVs, has chosen NORBIT as the most compact and user-friendly fully integrated MBES for mobile inspections on such vehicles.... (read more)

WASSP Launches New Rapid Deployment Multibeam Sounder

WASSP Multibeam has launched its new rapid deployment multibeam sounder – the W3 Rapid Deployment System (RDS). Revealed at the recently held Pacific Expo 2019 in Sydney, Australia, W3 RDS has been designed for navies, maritime police and search & rescue organizations for use where depths are unknown and to find safe navigation routes for larger vessels. When a fixed transducer installation in a small vessel such as a tender isn’t always practical, the W3 RDS has been designed around a portable Carbonfibre Mast that includes a transducer, motion sensor and satellite compass. This allows operators to deploy the unit... (read more)

Low-cost Expedition-ready Multibeam System

A new cost-efficient sonar bridging the gap between singlebeam echosounders and high-resolution multibeam sonar systems is the HydroBat, a multibeam system operating at 160kHz and covers a swath of 120°. Rich Lear at RESON explains the significance: "A task that used to take a week with the old singlebeam echosounders, takes only three days with this new multibeam HydroBat."  Designed to be simple and reliable, the new HydroBat from RESON is ready to meet the demands of serious hydrographic users in harbours and ports. Former software developer, Simon Barchard, states: "A really neat feature is the ability to run a... (read more)

Multibeam Mapping of Continental Margin Morphology

Bathymetry in understanding oceanic & continental evolution
A jigsaw puzzle of lithospheric plates comprises the outer shell of the earth. Oceanic plates, formed by ascending magma at mid-ocean ridges and transported towards the continents by internal convective forces, collide with continental plates at convergent margins and are subducted beneath them. This is accompanied by violent geological processes such as earthquakes, volcanic eruptions, submarine landslides and tsunamis. The speed of drift of the plates is in the order of several centimetres per year, too slow to be observed directly. Still, these processes shape the surface of the ocean bottom and submarine morphology records these forces acting on the... (read more)

Developments and Trends in Multibeam Echo Sounders

The multibeam echo sounders available on the market are constantly evolving as technology advances and as sonar producers seek new ways of refining and utilising the products. In this article we will provide a snapshot of current products and trends from the dominant (high-end) sonar producers focused on survey-grade products. Trend #1 – Resolution The neverending trend of getting higher resolution sonar systems is battling the physics of acoustics. Over the past several years, the battle for best-in-class multibeam for medium water depth has been between the Teledyne RESON SeaBat 7125, the Kongsberg EM 2040/2040C and the R2Sonic Sonic 2024....
