High-resolution Survey on Versatile USV

Skansen is a historic area in the city of Trondheim in central Norway and home to the Skansen Bridge, a 52m span bascule railway bridge that opens for marine traffic to access the Trondheim Fjord. The Skansen Bridge was built in 1918 and designed by structural engineer Joseph Strauss, who also designed the Golden Gate Bridge in San Francisco. The displacement of rocks and other objects in shallow waters over time can result in structural integrity issues for bridge piers such as the Skansen Bridge and hazards for vessel traffic, so that regular inspection of the structural integrity is required...

UKHO Announces Release of Seabed Mapping Service

The UK Hydrographic Office (UKHO) has launched a new beta version of its Seabed Mapping Service, now available via the ADMIRALTY Marine Data Portal. The ADMIRALTY Marine Data Portal is the UKHO’s portal for a wide range of marine data sets ranging from the seabed to the coast, offshore and beyond. This includes extensive data on bathymetry, wrecks and obstructions, along with a range of apps and APIs, to enable users to help inform a wide range of decisions to support a safe, secure and thriving future for the blue economy. The Seabed Mapping Service provides access to data that has... (read more)

Hydrospatial and the Marine Environment

The First Steps to Going Beyond Charting
Hydrographic offices (HOs) today exist in a world of accelerating technological change that is influencing human behaviour and creating new needs and ways of exploiting data to understand our world. HOs have traditionally been the producers of nautical information for safety of navigation. By the end of the 20th century, with the appearance of the IHO S-57 Standard, their main challenge was to evolve into a central database production system. Now, the critical challenge and opportunity is to evolve from there into a true geospatial agency, developing a hydrospatial information system (HIS) capable of providing products and services for multidimensional...

How an Ocean of Curiosity Led BCIT Geomatics Student to Pursue a Career as a Hydrographic Surveyor

A reflective gaze toward the open sea might be how some of us ponder one of life’s riddles or dream away a warm holiday afternoon. However, for a creative Vancouver Island student enrolled in the BCIT Geomatics Engineering Technology diploma programme, a curious glance across the waves is often to imagine what topographic mysteries lie below. Sian Cornwell loves the ocean and has a passion for topography. One of her favourite pastimes in high school was to convert topographic maps into 3D wooden terrain models. “It was art with real topographic maps,” she said. “I started to really enjoy it.” Using the...

USF and NOAA Launch Cooperative Ocean Mapping Center

The University of South Florida’s College of Marine Science has been awarded a five-year, US$9 million cooperative agreement by the National Oceanic and Atmospheric Administration’s (NOAA) Office of Coast Survey to launch the Center for Ocean Mapping and Innovative Technologies (COMIT). COMIT, located on the USF St. Petersburg campus, will develop new technologies and approaches to ocean and coastal zone mapping in line with NOAA’s commitment to building resilient coastal ecosystems, communities and economies.  “This partnership between the University of South Florida and NOAA will enable us to deliver detailed maps of the seafloor in the Gulf of Mexico,” said...

M&E Deploys Autonomous Survey Vessel on Florida Reef Survey

Morgan & Eklund (M&E) recently announced the successful completion of a multibeam and side-scan sonar survey to map and monitor an artificial reef offshore Fort Pierce along the Treasure Coast of eastern Florida. A post-construction survey was completed entirely using a SeaRobotics (SR) 'Surveyor Class' autonomous surface vessel (ASV). The objective of the survey was to verify seafloor conditions and accurate placement of artificial reefs. With its catamaran hull design, the SR-Surveyor M1.8 is an autonomous platform equipped with a multi-sensor package, that includes an EdgeTech 2205 multibeam echosounder, a 1,600kHz and 540kHz dual-beam side-scan sonar, an AML Oceanographic SV...

The Marine 2020s: Three Ambitious Global Projects

“In all beginnings dwells a magic force …”. Hermann Hesse’s famous verse seems to be particularly relevant to the coming decade when it comes to marine activities. Three ambitious global projects relating to the maritime domain will span the forthcoming 2020s. The broadest is no doubt the Decade of Ocean Science for Sustainable Development (2021-2030), spearheaded by the United Nations “to support efforts to reverse the cycle of decline in ocean health”. The second half of the proclamation “for Sustainable Development” seems to indicate two intentions: first, to link to the United Nations Sustainable Development Goals (2030), and second, to...

NOAA Institute Chooses DriX USV for Next-generation Ocean Exploration System

The Ocean Exploration Cooperative Institute (OECI), funded by NOAA’s Office of Ocean Exploration and Research (OER), recently signed a purchase contract to acquire a DriX Unmanned Surface Vessel (USV) from high-tech company iXblue. Signed over the summer, this contract consists of one DriX USV along with a novel custom-designed Universal Deployment System able to launch and recover the USV as well as other AUVs. The autonomous solution is expected to be put to sea by mid-2021. Along with the innovative Universal Deployment System, other features that led to the selection of the DriX were its mission endurance, ability to operate... (read more)

Seafloor Location of MV Nella Dan Mapped During Underwater Earthquakes Research

Australian scientists have for the first time mapped in high resolution the seafloor location of MV Nella Dan, a polar resupply ship that was sunk near Macquarie Island nearly 33 years ago. The 75-metre Nella Dan was damaged when it dragged its anchor in bad weather and was driven aground on Macquarie Island in December 1987. All on board were safely transferred to shore but, after careful inspection, the ship was deemed by its Danish owners to be too badly damaged to be salvaged. It was later towed out to sea and sunk in deep water. The location where Nella Dan sunk has now been... (read more)
