Robots probe ocean depths in mission to fine-tune hurricane forecasts

The robotic, unmanned gliders are equipped with sensors to measure the salt content (salinity) and temperature as they move through the ocean at different depths. The gliders, which can operate in hurricane conditions, collect data during dives down to a half-mile below the sea surface, and transmit the data to satellites when they surface. NOAA scientists are launching the underwater vehicles from ships off the coast of Puerto Rico; more gliders will be deployed later in the summer in other parts of the Atlantic.  When it comes to hurricanes, ocean conditions matter Water temperature and salinity provide important clues to...

Study Clarifies Influence Currents in the Atlantic Ocean on Sea Level Rise

A study by the Woods Hole Oceanographic Institution (WHOI) clarifies what influence major currents in the North Atlantic have on sea level along the northeastern United States. The study, published June 13 in the journal Geophysical Research Letters, a biweekly peer-reviewed scientific journal of geoscience published by the American Geophysical Union, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC), the zonally-integrated component of surface and deep currents in the Atlantic Ocean, and historical records of sea level in coastal New England. The AMOC is characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a... (read more)

Joined Forces to Reduce Fuel Consumption

Kongsberg Maritime has formed a partnership with DOF, SINTEF Ocean and NORCE, which aims to reduce fuel consumption and greenhouse gas emissions for complex offshore operations while streamlining fleet-wide maintenance. Enabled through sponsorship and support from Innovation Norway, the new partnership between four of Norway’s most maritime organizations will develop a new Decision Support System (DSS) for offshore vessel operations. This tool will act as the foundation for DOF to simplify operational complexity with objective measurement, ultimately enabling optimal utilization and more sustainable fleet management. Catalyze a Tangible Transformation Highlighting the potential of the partnership to catalyze a tangible transformation,... (read more)

Fugro to Support Climate Change Research in the Caribbean

Geo-data specialist company Fugro is embarking on a coastal mapping project in Jamaica and Haiti to support The Investment Plan for the Caribbean Regional Track of the Pilot Program for Climate Resilience. The work, which comprises approximately 2,000 square kilometres of integrated shallow water and land-based elevation data, was awarded to Fugro by the University of West Indies Mona with financing from the Inter-American Development Bank. Fugro will accomplish the project using its Rapid Airborne Multibeam Mapping System (RAMMS). Reduce CO2 Emissions Introduced in August 2018, RAMMS delivers depth penetration and point densities for nearshore and coastal mapping. Weighing just... (read more)

iXblue Conducts toFuture Groix & Belle-Île Pilot Wind Farm Geophysical Survey

iXblue’s Sea Operations division has been selected by EOLFI, the “Ferme Eolienne Flottante de Groix & Belle-Île” delegated project contractor, to conduct the geophysical survey of the future Groix & Belle-Île pilot wind farm located in the South of Brittany, off the West coast of France. The survey, that began earlier this week, will last for about five days and will be conducted by a dedicated crew of 5 iXblue hydrographic surveyors and geophysicist engineers onboard the company’s own Marine Renewable Energy (MRE) hydrographic research vessel, FeliX. "Our vessel has been designed and manufactured by our own shipyard and survey... (read more)

Dr. Gary Borstad Receives Val Shaw Memorial Award

ASL's Dr. Gary Borstad recently received the Val Shaw Memorial Award in recognition of his career-long contribution and lifetime achievements in practical remote sensing applied to natural resource management. This award was presented at the 40th Canadian Symposium on Remote Sensing in Fredericton, New Brunswick on June 25th, 2019. The Val Shaw Award was established in 1990 in memory of Val Shaw, an executive with the Bercha Group and a strong proponent of remote sensing in Canada. Remote Sensing Gary was educated at the Universities of Alberta, Paris, and McGill and has been active in remote sensing since 1975. With... (read more)

Exploring the Deepest Points on Planet Earth

Report on The Five Deeps Expedition
As extreme explorer Victor Vescovo continues his round-the-world expedition to become the first person to descend to the five deepest points in the Earth’s five oceans using the custom-built deep submergence vehicle Limiting Factor, it prompts the question: ‘Do we know as much about the deepest places on our planet as we thought?’ As extreme explorer Victor Vescovo continues his round-the-world expedition to become the first person to descend to the five deepest points in the Earth’s five oceans using the custom-built deep submergence vehicle Limiting Factor, it prompts the question: ‘Do we know as much about the deepest places on our planet as we thought?’ Today, the best global maps of the oceans have a resolution of 30 arc-second grid cells (926m at the equator). Approximately 82% of the grid cells do not include a single depth measurement (Weatherall et al., 2015), and the percentage of the seafloor that has been directly... (read more)

USGS and Scientists Test Drone-based Stream Gauging at 2019 Aquatic Airshow

The US Geological Survey (USGS) and independent scientists gathered recently in Auburn, Maine, to evaluate the use of sensor-mounted unmanned aircraft systems (UAS), or drones, to gauge stream stage, velocity, bathymetry, and discharge. The technology is being evaluated and modelled to determine whether it will support the fast, accurate and safe measurement of rivers, especially when they are flooded or contain floating trees, ice or other debris. Two Dozen Experts Close to two dozen hydrologic, geospatial and scientific experts gathered in what has been dubbed the '2019 Aquatic Airshow' to assess this technology. They were led by John Fulton of... (read more)

Falcon Flies In Canada's First Nation Waters

The University of Victoria has engaged Ocean Dynamics to deploy a Saab Seaeye Falcon robotic vehicle for the inspection of instrumentation platforms monitoring the ocean around Canada’s north-west coast, particularly in First Nation coastal waters. A total of 50 instrumentation platforms, together with six observatories are plugged into over 900 kilometres of fibre-optic cable on the seafloor giving internet access to marine scientists and coastal communities to enable evidence-based decision-making on ocean management, disaster mitigation, and environmental protection. The University’s world-leading Ocean Networks Canada undertaking was launched in 2006 with the first “wired” seafloor observatory. Since then, community observatories have... (read more)
