Department of Fisheries and Oceans Canada Inspects the High Arctic

The Department of Fisheries and Oceans Canada in Manitoba will use a SEAMOR Marine Remotely Operated Vehicle (ROV) to inspect the High Arctic area which remains frozen year-round. The Chinook ROV will take part in research and evaluating ways to protect this special ecological region. The vehicle will also be used to conduct ecosystem identification and benthic surveys (underwater mapping of the seafloor) and inspection of first-year ice and multi-year ice. Auto-altitude system SEAMOR Marine's Chinook ROV will be equipped with a handheld pendant controller, and a fibre optic tether multiplexer upgrade. These will help control a wide array of...

Next-generation USV to Launch at Ocean Business 2019

Unmanned Survey Solutions (USS) has designed and built the next-generation Accession Class Unmanned Survey Vessel (USV) for use in nearshore and offshore hydrographic surveys. The device will launch at Ocean Business in April 2019. The unique modular design of the USV allows the vessel to increase its base design length of 3.5m to a maximum of 5m for additional payload equipment and/or power for extended endurance depending on operational requirements. James Williams, director at USS, said “We wanted to build a USV that was truly versatile, reliable and robust enough to withstand operating in offshore conditions while keeping it simple...

Seabed 2030 and Five Deeps Sign Agreement

Seabed 2030 and the Five Deeps Expedition have signed an agreement which lays the groundwork for previously unexplored areas of the seafloor to be mapped and the resulting data made available for public use. Seabed 2030 is the collaborative project of The Nippon Foundation and GEBCO aspiring the complete seabed mapping by 2030. In this cooperation with the Five Deeps Expedition, the world's first manned expedition to the deepest point in each of the five oceans, the Seabed project is ensured of data contributions in areas which would not have been collected otherwise. In addition to data gathered at trench sites,... (read more)

Uncovering the Mysteries of the Oceans

What is Oceanography and How to Become an Oceanographer
This article will dig into the field of Oceanography and the trends and methods developed over the past decades. Did you know that marine species compound more than 80% of the Earth’s biodiversity? Or that seaweed and other sea plants living in the ocean produce around 50% of the oxygen in the atmosphere? With this in mind, many efforts are now concentrated on studies of the ocean, such as identification of those beneficial to ocean resources and organisms that can be used as medicines for many critical ailments. Within this article, you will also get familiar with terms like biomimicry,... (read more)

Web GIS Improves Lidar Collection Response Time

The remarkable capabilities of airborne Lidar continue to improve, with scanners now able to emit more than a million pulses every second. Although it has never been easier to acquire high-quality laser data, storing and managing the huge volume of Lidar data collected can prove to be a challenge. Combined with associated metadata such as survey information, environmental conditions and flight lines, data management has now become a critical priority and focus. This article outlines an initiative called the Lidar Management and Analytical Processing (LMAP) that provides an automated workflow for uploading and storing Lidar and metadata into a Geographic...

SDB Day 2019

SDB Day 2019, an international Satellite-Derived Bathymetry Technology and User Forum, will be hosted by EOMAP Australia and will take place on the beautiful Sunshine Coast of Queensland in Australia, at the Mantra Mooloolaba Beach Resort on 14-16 May 2019. Satellite-Derived Bathymetry (SDB) has experienced accelerating uptake in recent years, with users from industry, government and academia using this cost-effective and reliable method for multi-disciplinary hydrographic seabed mapping projects, hydrodynamic modelling, reconnaissance surveys and environmental campaigns across the globe. As SDB is now being considered as an established survey technology, it is increasingly important that both users and providers worldwide have a venue... (read more)

Sonar Plays Integral Role in First Human Reaching Deepest Point in Atlantic

Kongsberg Maritime has announced that the EM 124 sonar, installed aboard the DSSV Pressure Drop, played a key role in the deepest solo human submersible dive completed by the Five Deeps Expedition. Expedition founder and submersible pilot, Victor Vescovo, reached the bottom (depth of 8,376 metres) of the Puerto Rico Trench in his private submersible, the Limiting Factor, following precision mapping of the ocean floor completed by the EM 124. The Kongsberg EM 124, released in 2018, is the fifth generation multibeam system from Kongsberg Maritime and the successor of the EM 122. It is a modular multibeam echosounder that... (read more)

Choosing the Right Sonar Imaging System for Autonomous Underwater Vehicles

Multi Aperture Sonar - a Low-logistics Alternative to SAS
Underwater vehicle operators have to make a choice when deciding on a sonar imaging system to integrate on their systems. The decision could result in a trade-off, with a choice to be made between achieving high levels of range and resolution, and power and weight budgets. The decision made can impact the value of the subsea survey, classifying and mapping operations. But does it always have to be a trade-off?  What is a Multiple Aperture Sonar? In multi-aperture sonar (MAS), the dynamically focused multibeam input from 32 elements is used to extend the focus along the whole swath. Multiple apertures... (read more)

Using RAMMS to Acquire Integrated Land and Sea Data in the Caribbean

Fugro has completed a data acquisition campaign over the Turks and Caicos Islands, marking the first commercial success of its Rapid Airborne Multibeam Mapping System (RAMMS). Working under contract to the United Kingdom Hydrographic Office (UKHO), the company acquired more than 7,400 square kilometres of integrated, high-resolution bathymetric, topographic and image data. The resulting deliverables will support updated nautical charts and coastal zone management activities in the region. Launched in August 2018, RAMMS is a airborne bathymetric mapping system that uses multibeam laser technology to deliver industry-leading depth penetration and point densities. The compact sensor is deployed from a small aircraft... (read more)
