This Is How Sonar Noise Can Be Cleaned And Classified

Teledyne CARIS, a Teledyne Technologies company, has announced the release of HIPS and SIPSTM 11.3. This new software upgrade will introduce the first-ever COTS (commercial-off-the-shelf) release of an AI solution for classifying and cleaning sonar noise. Teledyne CARIS seeks to reduce significantly the need for manual cleaning and to move data swiftly from acquisition to review. The Sonar Noise Classifier automatically identifies the vast majority of sonar noise, resulting in a reduction of manual cleaning effort by a factor of up to 10x at an accuracy of 95%. This allows the hydrographer to focus more time on other important aspects... (read more)

Easy Ways to Utilize Hydrographic Survey Data

Maritime software company QPS and GISGRO, an online platform created by the Finnish high-tech company VRT Finland, have joined forces to enhance the utilization of hydrographic data. Integration of the two software in March 2020 will provide hydrographic surveyors with an easy way to share the complex 3D data with their clients, who can gain major benefits by further sharing and utilizing the data in their daily operations. Digital 3D modelling has reached the underwater world; for example, in forms of seabed scanning for safe navigation and scanning of underwater structures for maintenance purposes. The constantly growing amount of digital... (read more)

Woolpert Starts Acquiring Bathymetric Lidar Data of Saint Lucia’s Coastal Zone

The Woolpert-GDS Joint Venture (JV) has been contracted to acquire topographic and bathymetric lidar data of the Caribbean island Saint Lucia’s entire landmass and coastal zone. The contract was signed under the World Bank’s Disaster Vulnerability Reduction Project (DVRP), which aims to measurably reduce vulnerability to natural hazards and climate change in Saint Lucia and the Eastern Caribbean Region. High-resolution, 3D lidar data has proved effective around the world in mapping and modelling landscapes and environments, helping policy-makers make informed decisions about how best to utilize resources to prepare for and recover from weather-related disasters. Flood Modelling According to a... (read more)

This Undersea Imaging Technology Helps Oceanographers and Researchers

Video Included
Robust recovery of lost colours in underwater images remains a challenging problem, say engineer and oceanographer Derya Akkaynak and Tali Treibitz, her postdoctoral research advisor, of the University of Haifa and the Leon Charney School of Marine Sciences (Israel). They recently showed that this was partly due to the prevalent use of an atmospheric image formation model for underwater images and proposed a physically accurate model. The revised model showed that the attenuation coefficient of the signal is not uniform across the scene but depends on object range and reflectance. They also showed that the coefficient governing the increase in backscatter with distance...

“Blue technology industries will help the expansion of the hydrographic market”

A view of hydrographic technology and the market for 2020
In the last decade, there has been a steady march towards the automation of hydrographic data collection. Jim Gardiner, a research scientist at Valeport, views the technical and commercial challenges in hydrographic operations. In the last decade, there has been a steady march towards the automation of hydrographic data collection. Jim Gardiner, a research scientist at Valeport, views the technical and commercial challenges in hydrographic operations. In terms of multibeam technology, we’ve seen continual advancements from the main players such as Teledyne Reson, Kongsberg, R2Sonic and the emergence of Norbit. Alongside this, there has been a steady improvement in GPS, inertial positioning systems and acquisition/processing software. As the capability of these systems has improved, it has placed a focus on the importance of accurate and reliable sound velocity data. To achieve accurate bathymetry,... (read more)

Netherlands-based Fugro Gets NOAA Survey Contract

NOAA, the US National Oceanic and Atmospheric Administration, has contracted with Netherlands-based Fugro to provide five years of hydrographic surveying services in the United States. The contract was issued by NOAA’s National Ocean Service, Office of Coast Survey, to support the creation and maintenance of highly accurate nautical charts. Fugro has worked continuously with the agency on similar contracts since 1998. “Over the past 20 years, NOAA has been one of Fugro’s key clients in the US,” said Mark MacDonald, hydrography director for Fugro in the Americas. “Through this long and valued partnership, we have pioneered the use of multiple...

This Is How Airborne Multibeam Lidar Coastal Mapping in Paradise Is Done

Insights from the first commercial use of Fugro RAMMS
The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradisal Turks and Caicos Islands.

Scientists Discover Roman Shipwreck Dating Back to Time of Jesus Christ

In October, a scientific team from the Balearic Institute of Maritime Archaeology Studies found a Roman cargo ship with jugs containing olive oil and perfectly preserved garum sauce, an ancient form of ketchup. Scientists have discovered the extremely large Roman shipwreck dating back to the time of Jesus Christ. The ship and its cargo could reveal new information about shipbuilding and trade during that time period. The sunken vessel was recently discovered off the coast of Greece, near Kefalonia Island, during a survey conducted by the Oceanus Network of the University of Patras, Greece.
