How to Derive Shallow-water Bathymetry Measurements From Satellites

TCarta Marine, a provider of marine geospatial products, is commercializing a new technique to derive highly accurate shallow-water bathymetry measurements from NASA’s ICESat-2 satellite data. The new methodology is being developed with funding from the National Science Foundation (NSF). In 2018, NSF awarded the company a Phase 1 Small Business Innovation Research (SBIR) grant to commercialize new satellite-derived bathymetric (SDB) measurement technologies. Referred to as Project Trident, the research focused on leveraging Artificial Intelligence (AI) - machine learning and computer vision - to determine shallow-water seafloor depth in variable water conditions.

This Is How 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 paradise Turks and Caicos Islands. 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 paradise Turks and Caicos Islands. In July 2018, Fugro embarked on a large-scale project to map the Turks and Caicos Islands for the United Kingdom Hydrographic Office (UKHO). This landmark effort called for integrated, high-resolution bathymetric, topographic and orthoimage datasets to support nautical chart updates and coastal zone management activities. To achieve the sizeable bathymetric portion of the... (read more)

How Scientists Use Satellite-mounted Laser to Map Global Ocean Migration

A study published in the 12 December issue of Nature reports on the use of satellite-borne lidar to map the daily vertical migration of zooplankton across the world’s seas over the course of a decade. On Williams Yorktown Daily, a US-based news site, lead author Michael Behrenfeld of Oregon State University says, “What the LiDAR allowed us to do is sample these migrating animals on a global scale every 16 days for ten years. We’ve never had anywhere near that kind of global coverage to allow us to look at their behaviour, distribution, and abundance.” On the study were researchers from... (read more)

This Vast Animal Migration is a Critical Part of Earth’s Climate System

Every night, under the cover of darkness, countless small sea creatures – from squid to krill – swim from the ocean depths to near the surface to feed. This vast animal migration – the largest on the planet and a critical part of Earth’s climate system – has been observed globally for the first time thanks to unexpected use of a space-based laser. Researchers observed this vertical migration pattern using the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite – a joint venture between NASA and the French space agency, Centre National d'Etudes Spatiales – that launched in 2006....

How to Carry Out an Asset Inspection Survey

Bibby HydroMap, a UK-based company, has successfully completed an asset inspection survey of several bridges and the Weaver Sailing Club along the River Weaver in Cheshire (UK). This was an opportunity to demonstrate its marine 3D imaging capabilities in a highly dynamic and fast-flowing environment. The River Weaver is a marine connection between a number of businesses along the river and the Manchester Ship Canal and, ultimately, the Irish Sea, the integrity of which is paramount to their commercial operations. Locate Any Obstructions to Navigation The aim of the survey was to assess the condition of the bridges which span the... (read more)

Scanning Sonar for Poor Visibility Underwater Environments

US-based Blue Robotics is launching the Ping360 Scanning Sonar, which offers small ROVs the ability to navigate in low visibility water conditions. The Ping360 is a mechanical scanning sonar – it uses a small acoustic transducer mounted on a motor that rotates it in one-degree increments. As it rotates, it transmits and receives acoustic pulses to build a 360-degree image of the surroundings. This is similar to laser scanners and LIDARs used for ground robotics and autonomous cars, but using sound waves instead of light. Maximum Water Depth of 300 Metres When mounted on a remotely operated underwater vehicle (ROV),... (read more)

WASSP Technology Utilised by US University Students

Oceanography students at the University of Rhode Island have been busy utilising the latest in WASSP Multibeam technology as part of their research studies. The students, who are specialising in marine robotics, remote sensing and mapping have recently started using a WASSP S3 Multibeam system as part of a project to survey inland ponds and coastal estuaries. They have deployed the WASSP Multibeam system aboard a specially developed autonomous kayak.  WASSP, an acronym for Wide Angle Sonar Seafloor Profiler, is a multibeam sonar system manufactured by ENL Group in New Zealand under ISO9001/2000 certification. Research and development of WASSP commenced in... (read more)
