Hydroacoustic Studies of Eulachon Fish Distribution Related to Roberts Bank Terminal 2 Project

ASL Environmental Sciences (ASL) was chosen by Hemmera Envirochem Inc. and the Vancouver Fraser Port Authority (port authority) to perform a hydroacoustic study of eulachon fish (Thaleichthys pacificus) distribution in the vicinity of Deltaport Terminals off the mouth of the Fraser River, BC.  To support the development of the Dredging and Sediment Discharge Plan that will form part of the Construction Environmental Management Plan of the Roberts Bank Terminal 2 Project (project), the port authority has committed to developing eulachon-specific mitigation that will be used during dredging activitie

Florida Current is the Weakest Its Been in a Century

The Florida Current, which forms the start of the Gulf Stream, has slowed over the past century and is the slowest it has been at any point in the past 110 years, a new study reveals.Researchers have developed a method of tracking the strength of near-shore ocean currents using measurements made at the coast, offering the potential to reduce one of the biggest uncertainties related to observations of climate change over the past century.“In the ocean, almost everything is connected,” said Christopher Piecuch, an assistant scientist in the Physical Oceanography Department at the Woods Hole

The Benefits of Sustainable Marine Lumber

Today’s marinas are held to a higher standard of environmental stewardship than in the past. No longer are they just responsible for the environmental impacts of their day-to-day operations, but also of their infrastructure and how it affects both the oceans, waterways and their delicate marine ecosystems. For these reasons, many marinas are being far more selective as to construction materials being specified for their expansion and/or restoration projects.One material that is rising to the top for its eco-friendly and performance attributes is sustainable marine lumber.

Professor Mike Allen of the University of Exeter and Plymouth Marine Lab explained the need for an economically and environmentally viable method: “Processing marine biomass like seaweed usually requires removing it from the saltwater, washing it in fresh water and drying it. The costs of these processes can be prohibitively high.”As a solution, the team

The vents, located in a valley about 14 kilometres (8.6 miles) long and 1.5 kilometres (0.9 miles) wide, has been studied previously, but never mapped until now because of difficult access.Hydrothermal vents are created by magma beneath the seafloor that heats water within the surrounding bedrock, emerging from the seafloor in the form of underwater seeps and geysers.

ASL's 2020 Early Career Scientist Contest

scientists and engineers, graduate students, post-doctoral fellows and others involved in oceanographic or freshwater work.With the unmatched combination of multiple frequency operation, low power and extended endurance, the ASL AZFP offers a new, economical way of obtaining reliable measurements of marine environmental conditions in the water column. The AZFP can monitor the presence and abundance of zooplankton and fish within the water column by measuring the acoustic backscatter returns at multiple ultrasonic frequencies. Other sonar targets realized from the sonar backscatter data include bubbles

Unique Group Develops UXO Recovery System

its expertise in survey and buoyancy technology with Dutch UXO experts, Bodac, to develop an Unexploded Ordnance Lifting & Safe Disposal System (UXO-LSDS), which paves the way for contactless mine recovery.Bodac’s experience in UXO risk mitigation and explosive engineering services in the marine environment has been integrated with Unique Group’s technical expertise to develop the UXO-LSDS, which consists of a housing for two 9l, 300 bar composite cylinders and a Sonardyne Acoustic Lightweight Release Transponder (LRT).Working with known UXO weights and water depths, the UXO-LSDS can

Chinese Port Using Robots to Deploy Mooring Lines

A passenger port in Zhuhai, China has created a new solution using aquatic robots for long distance line deployment.Earlier this month, Zhuhai Jiuzhou Port carried out a series of typhoon-proof reinforcement work for their floating barges. The staff used a small self-powered jet pump device called Dolphin 1 to transport a traction rope, which was attached with the mooring line, to the opposite shore 230 meters away.After the traction rope was transported to the opposite shore, staff used a forklift to pull the mooring line ashore and tightened it to the pile.Every year from June to August is the high

Deep will upgrade one of its survey vessels with a Sea Machines SM300 autonomous control system. This system enables remote command of the vessel, including navigation and positioning, the control of on-board auxiliaries and sensors, and ship-to-shore data flow. The vessel, operating in multiple areas of the Wadden Sea, will be commanded by personnel in the Amsterdam office. (Photo: © Deep BV)

Hydrographic Survey Vessel to be Converted for Unmanned Operations

enabling surveyors to remotely monitor and command multiple autonomous vessels from a shipboard or shore-based center located anywhere with network connectivity. This remote capability also reduces or removes high-risk activities generally associated with crew working aboard small survey craft in dynamic marine environments. By breaking the 1:1 crew-to-vessel relationship, companies can better utilize their technical experts across multiple concurrent projects, the company said.In September 2019, Deep was the first company to conduct remote surveys without surveyors on board in The Netherlands. These early

Dutch Flood Defense, The Natural Way

When the Dutch government and research institutions wanted to monitor how waves and currents would affect the pioneering use of artificial sand banks to protect a levee in a non-tidal freshwater system, Nortek was selected to supply key measuring instruments and set up the data telemetry system.The Houtribdijk is a 25 km long levee, or dike, separating two large artificial lakes, the IJsselmeer and Markermeer. The lakes and accompanying levees protect the Netherlands from the forces of the North Sea’s extreme weather events, and from flooding from inland freshwater river systems.After years of
