MBARI: Hydrothermal Mapping is Heating up

A recent paper by Monterey Bay Aquarium Research Institute (MBARI) has revealed almost 600 hydrothermal chimneys around the Endeavour Segment of the Juan de Fuca Ridge, about 350 kilometres (220 miles) northwest of Washington State. 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.

Deep Sea Mining Could Destroy Undiscovered Species, Says Ocean Panel

Mining on the sea floor should not begin before a full assessment of likely environmental impacts can be made, a report commissioned by the High Level Panel for a Sustainable Ocean Economy (Ocean Panel) said on Wednesday.Environmentalists including Britain's David Attenborough have called for a ban on deep-seabed mining that would extract resources including copper, cobalt, nickel, zinc, lithium, and rare earth elements from nodules on the ocean floor.The International Seabed Authority (ISA), a U.N. body headquartered in Jamaica, has drawn up regulations on exploration, but has yet to establish

Fast-moving Waterfalls in the Deep Sea

New research led by the National Oceanography Center (NOC) has discovered how fast-moving waterfalls under the sea control the shape and behavior of submarine channels. These underwater channels are the offshore equivalents of rivers, but can be much larger. Submarine channels can extend for tens to thousands of kilometers offshore, providing an important conduit for the transfer of sediment, nutrients and pollutants, such as microplastics, to the deep-sea. Avalanches of sediment that flow down these channels also pose a hazard to networks of seafloor cables that underpin global communications,

A unit recently arrived in western Panama where one of the country’s hydroelectric generation companies has begun using it for tunnel inspections of two hydroelectric projects on the Old Chiriqui River.  “We are excited to bring this new innovation to the pipeline industry,” said Robin Li, President of Seamor Marine. “The ROV 3-kilometer fiber optic tether and reel system expands the range of our vehicles from two

Case Study: Helping Ocean Researchers Obtain Hi-Resolution Measurements at a Lower Cost

Understanding the three-dimensional nature of the ocean is becoming a critical focal point of ocean research, but it can be a costly affair.Paired with Nortek current profilers, Del Mar Oceanographic’s Wirewalker is giving researchers from around the globe a cost-effective way to answer vital questions surrounding the functioning of ocean processes. This information helps improve environmental monitoring and climate forecasting, which in turn assists in developing measures to adapt to our changing climate.Information on the three-dimensional structure of the ocean is proving increasingly vital

Meterologists, Oceanographers Help Pave a Safe Path for USN Hospital Ships

USNS Mercy (T-AH-19) arrived safely in Los Angeles last week and USNS Comfort (T-AH-20) arrived safely in New York on Monday. While the Navy’s hospital ships prepare to receive patients, Naval Oceanography’s team of meteorologists and oceanographers ensured these ships were safe from hazardous weather as they traveled to their destinations.On March 20, Fleet Numerical Meteorology and Oceanography Center (FNMOC) rapidly configured two ship-following coupled ocean/atmosphere mesoscale prediction systems (COAMPS) for the USNS Mercy and Comfort. The center of these high-resolution weather

Kraken Debuts Ultra High Def Upgrade for AquaPix Imaging Sonars

Kraken Robotics Inc. announced it has achieved a practical resolution of 2 cm with a Commercial-Off-The-Shelf (COTS) Synthetic Aperture Sonar (SAS), Kraken’s AquaPix MINSAS.“For demanding subsea survey missions in mine countermeasures, infrastructure monitoring and oil & gas exploration; data quality is of the essence," said Karl Kenny, Kraken’s President & CEO. "The sensor that gets the job done most effectively is one that combines Ultra High Definition (Ultra HD) imagery with an extremely high area coverage rate.  Kraken’s latest development, the next

Environmental DNA Emerging in the Ocean Science Community

hundreds or thousands of years. But in aquatic environments, the DNA released by an organism can be detected for only a few days. Despite this, the ocean science community is eager to employ this relatively new tool. In late November 2018 approximately 100 ocean scientists and stakeholders interested in marine eDNA assembled at The Rockefeller University in New York City for a conference sponsored by the Monmouth University-Rockefeller University (MURU) Marine Science and Policy Initiative. The executive summary of this gathering made it clear: “eDNA works. Get going.”But what does that mean

SubSeaSail G6 Platform Passes the Test

The Engineer Research and Development Center (ERDC) of the U.S. Army Corps of Engineers (USACE) along with logistical support from the US Navy successfully tested their SubSeaSail G6 platform at multiple coastal sites off the Vieques Island, Puerto Rico. Remote sensing applications for monitoring underwater unexploded ordnance were demonstrated by mounting a passive filter assembly to the G6 platform to detect explosive compounds in the water. Additionally, a water quality sensor was mounted to monitor other water quality parameters including temperature, salinity, depth, and turbidity.  During
