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)

Investigating a Non-polluting Alternative to Diesel Engines

Marine research and hydrographic activities could soon be possible without the risk of polluting either the air or the ocean thanks to a zero-emissions ship design and feasibility study led by Sandia National Laboratories. Hydrogen fuel cells have existed for decades, and there are multiple advantages to using them instead of diesel engines to power research ships. For example, with zero-emissions technology, fuel cells will not contaminate air or water samples collected in sensitive ecological areas. Additionally, they make almost no noise, so they will not upset marine life or interfere with the many sensors scientists use to listen to... (read more)

Pioneer Grows Saab Seaeye Falcon Fleet

ASI Marine, a pioneer in long tunnel excursions and international operator for inland marine work, is expanding its Saab Seaeye Falcon fleet. Renowned for being the first to exploit the Falcon’s adaptive intelligent technology by sending the 300 metre rated remotely operated underwater vehicle on a five-kilometre-long tunnel inspection, the company is now adding the 1,000 metre rated Falcon version to their collection. Inland Operations Bob Clarke, manager of ROV services at ASI Marine, said “We are familiar with the Falcon’s potential, its operation and its maintenance. It’s also compatible with umbilical tethers already in our inventory and it is... (read more)

Unique 3D Habitat Map of the Great Barrier Reef

International aquatic remote sensing company EOMAP recently showcased its unique contribution to the world's first 3D habitat map of the Great Barrier Reef (GBR) at the International Forum on Satellite-Derived Bathymetry (SDB Day 2019) in Australia. The mapping project, titled ‘3D live habitats for the full extent of the Great Barrier Reef’, will for the first time provide maps of the predicted coral types and underwater landscape for the more than 3,000 reefs within the 350,000 square kilometres of the GBR. EOMAP’s cutting-edge technology provides essential data for this revolutionary project, in which the University of Queensland (UQ), Great Barrier Reef Marine Park... (read more)

CSA Completes Field Surveys Offshore Puerto Rico

CSA Ocean Sciences (CSA), under a subcontract to Jacobs, has announced the completion of a comprehensive environmental monitoring survey. The survey included physical, biological and chemical field sampling and data collection for 301(h) waiver demonstrations at the Aguadilla, Arecibo and Ponce Regional Wastewater Treatment Plant (RWWTP) outfalls offshore Puerto Rico for the Puerto Rico Aqueduct Authority (PRASA). Since 1999, CSA has been helping to evaluate compliance with receiving water quality standards and describe environmental conditions. Acoustic Doppler Current Profilers During this recent survey, CSA deployed and retrieved acoustic Doppler current profilers (ADCPs), a conductivity-temperature-depth (CTD) water profiler with ancillary sensors...
