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 ...
Within the United States National Weather Service (NWS), forecast weather maps began to be published by offices in New York City, San Francisco, and Honolulu for public use. North Atlantic forecasts were shifted from a closed United States Navy endeavor to a National Weather Service product suite via radiofacsimile in 1971, while northeast ...
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 .
The main factors affecting sea level are the amount and volume of available water and the shape and volume of the ocean basins. The primary influences on water volume are the temperature of the seawater, which affects density , and the amounts of water retained in other reservoirs like rivers, aquifers, lakes , glaciers, polar ice caps and sea ...
These factors can each influence the safety of marine transit. Consequently, a variety of codes have been established to efficiently transmit detailed marine weather forecasts to vessel pilots via radio, for example the MAFOR (marine forecast). [104] Typical weather forecasts can be received at sea through the use of RTTY, Navtex and Radiofax.
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."
According to Fisheries and Oceans Canada 2023, the Estuary and Gulf of St. Lawrence planning area covers most of the Estuary and Gulf of St. Lawrence bioregion, an area with some of the warmest surface waters in Atlantic Canada during summer and the largest amount of sea ice during winter. The planning area is approximately 240,000 km².
Weather ship G ("George") was dropped from the network on July 1, 1949, and Navy weather ship "Bird Dog" ceased operations on August 1, 1949. [8] In the Atlantic, weather vessel F ("Fox") was discontinued on September 3, 1949, and there was a change in location for ships D ("Dog") and E ("Easy") at the same time. [7]
