In 2015, the Hanna Shoal region of the Chukchi Sea shallower than the 40 m isobath was withdrawn from outer continental shelf oil and gas exploration, a move the White House noted was designed to protect areas of “critical importance … for marine mammals, other wildlife, and wildlife habitat”. Arctic regions are projected to strongly manifest impacts of an altered climate and subsurface moored continuous...
EMSO (European Multidisciplinary Seafloor and water-column Observatory; http://www.emso-eu.org) is a large-scale European Research Infrastructure (RI) of the ESFRI roadmap composed of fixed-point, seafloor and water-column observatories with the basic scientific objective of near- and realtime, long-term monitoring of environmental processes related to the interaction between the geosphere, biosphere,...
Natural phenomena, such as solar flare and sporadic E layer, have some influences on radio propagation characteristics. Since radio waves are utilized for many broadcasting and communications systems today, it is important to observe the influences of the natural phenomena on radio propagations. And it is also useful to observe the radio propagations for a long term and in different propagation paths...
EMSO, an ESFRI large-scale Research Infrastructure (European Strategy Forum on Research Infrastructures Roadmap), is the European-scale network of multidisciplinary seafloor and water column observatories from the Arctic to the Black Sea with the scientific objective of long-term real-time monitoring of processes related to geosphere/biosphere/hydrosphere interactions. EMSO will enhance our understanding...
Our understanding of physical and biogeochemical processes in the Arctic, especially related to marine ecosystems, is rudimentary yet it is precisely here where we are witnessing the most rapid and profound impacts of global environmental change. Many national and international organizations have stressed the need for long term monitoring of Arctic ecosystems to understand better how they function...
Canada has gained a world-leading position in the science and technology of cabled ocean observing systems, principally through the federal and British Columbia (BC) government investments ($120M) in the VENUS and NEPTUNE Canada ocean observatories, now deployed in coastal to deep ocean waters off BC's West Coast. The combination of continuous power, high bandwidth and real-time data streaming make...
To assess hydrodynamics and particle transport variability at the Arctic shelf-basin boundary, a bottom-moored marine observatory was maintained from October 2003 to October 2006 over the ca. 300 m isobath on the slope of the Canadian Beaufort Sea (western Arctic Ocean). The mooring line was equipped at ~200 m depth with an oceanographic multi-sensors and a sequential sediment trap. Each winter, an...
