A continuous marine broadcast, or CMB, is a marine weather broadcasting service [1] operated by the Canadian Coast Guard. CMBs are programmed from the various Marine Communications and Traffic Services centres on the Atlantic, Pacific and Arctic coasts of Canada , as well as on the coasts of the Great Lakes .
2013 map of Ocean Networks Canada installations along the Endeavour segment of the Juan de Fuca mid-ocean ridge in the northeast Pacific. This site is part of the NEPTUNE observatory. Endeavour (depth 2200–2400 m) is a northern segment of the Juan de Fuca Ridge which, in turn, is part of the complex, 80,000 km long mid-ocean ridge system ...
Between 1986 and 1989, [8] the portion of the National Meteorological Center (NMC) known as the Ocean Products Center (OPC) was responsible for marine weather forecasting guidance within the NWS. [9] Between August 1989 and 1995, the unit named the Marine Forecast Branch also was involved in providing objective analysis and forecast products ...
Marine weather forecasts by various weather organizations can be traced back to the sinking of the Royal Charter in 1859 and the RMS Titanic in 1912. The wind is the driving force of weather at sea, as wind generates local wind waves, long ocean swells, and its flow around the subtropical ridge helps maintain warm water currents such as the ...
Weather Buoy / Data Buoy / Oceanographic Buoy operated by the Marine Data Service. The first known proposal for surface weather observations at sea occurred in connection with aviation in August 1927, when Grover Loening stated that "weather stations along the ocean coupled with the development of the seaplane to have an equally long range, would result in regular ocean flights within ten years."
The Coastal-Marine Automated Network (C-MAN) is a meteorological observation network along the coastal United States. Consisting of about sixty stations installed on lighthouses, at capes and beaches, on near shore islands, and on offshore platforms, the stations record atmospheric pressure, wind direction, speed and gust, and air temperature; however, some C-MAN stations are designed to also ...
A tsunami warning was issued Thursday morning following a 7.0 magnitude earthquake that struck in Humboldt County, 7 miles west-southwest of Ferndale, Calif., the National Weather Service said in ...
If there is long-term wave data available in a nearby offshore location (e.g. from satellites), a wind wave model can be employed to transform the offshore wave statistics to the nearshore location (provided the bathymetry is known). Often, long-term local measurements of wave conditions due to extreme events (e.g. hurricanes) are missing.
