Basin site in late July. The collection of detailed measurements over two years will assess the deep-sea site, approximately 200 kilometers southeast of Vancouver Island, for future use.“A potential full-scale neutrino observatory at Cascadia Basin would benefit particle physics, astrophysics, ocean science and marine biology by offering reliable long-term detection capabilities,” said Benoit Pirenne, ONC’s executive director of user engagement.The equipment being used to detect neutrinos is also sensitive to bioluminescence, providing scientists with data to study trends in this emission

Mappers Look to Chart World's Ocean Floor by 2030

, the U.N. secretary general's special envoy for the ocean, said he was "very aware ... of the mineral aspects" of exploring the seabed, adding that the main charting activity would be from the scientific community."The United Nations has adopted a resolution to have a decade of ocean science for sustainable development running from 2021 to 2030. And during that decade I'm very confident we will have totally mapped the floor of the ocean."(Additional reporting by Stuart McDill; Editing by Dale Hudson

of how ocean conditions influence the zone size.“The data collected from this annual, long-term research program is critical to our understanding of a wide range of Gulf issues including hypoxia and beyond,” said Steven Thur, Ph.D., director of NOAA’s National Centers for Coastal Ocean Science. “Not only is measuring the size of the Gulf of Mexico dead zone vital to informing the best strategy to reduce its size, but also to reduce its impacts on the sustainability and productivity of our coastal resources and economy.”These nutrients stimulate massive algal growth that

also provide more responsive control and advanced health monitoring of subsea equipment.But, this new infrastructure could support more than pumps, compressors and actuators. It could also be used to support a growing fleet of unmanned underwater vehicles, as well as supporting other industries, from ocean science to deepsea mining.“Once you have power down there, you can power ROVs (remotely operated vehicles), heating in pipelines (to prevent blockages), and a number of other applications, that are coming up,” says Jan Bugge, Vice President of subsea technology at ABB and Project Director

a Moving Vessel Profiler (MVP) for the research vessel Jia Geng.   The university’s State Key Laboratory of Marine Environmental Science will use the deep water underway profiling system, MVP300, to collect CTD, sound velocity and environmental data in support of both hydrographic and ocean science applications. The ability to collect high density data in real-time while the vessel is underway will produce higher quality results than can be achieved with static profiling systems, and in a fraction of the time.   The contract was secured through manufacturer AML Oceanographic&rsquo

These ADCPs are installed in three different ways: Shallow Profiler Moorings (SPM), Benthic Experiment Packages (BEP), and Seafloor Instrument Arrays (SIA).    Water-Column Processes One focus of the Cabled Array is water-column processes. Topics studied span all facets of ocean science. Some promote cross-discipline cooperation, such as biological-physical coupling, while others entrain citizen science. Sustained observing tackles understanding environmental impact and anticipated climate changes. Long-term observing at high sampling rates will reveal both rapid and slow-changing
