Mariners Weather Log

The Mariners Weather Log (MWL), a publication of the National Weather Service (NWS), contains articles, news and information about marine weather events and phenomena, storms at sea, weather forecasting, the NWS Voluntary Observing Ship (VOS) Program, Port Meteorological Officers (PMOs), cooperating ships officers, and their vessels.

The MWL provides meteorological information to the maritime community, and contains a comprehensive chronicle on marine weather. Through the MWL, the VOS program recognizes ships officers for their efforts as voluntary weather observers, and allows the NWS to maintain contact and communicate with over 10,000 shipboard observers (ships' officers) in the merchant marine, NOAA Corps, Coast Guard, Navy, etc.

The MWL is currently published three (3) times per year (April, August, & December), and has a circulation of approximately 3000 copies distributed to mariners, marine institutions, the shipping industry, scientists, educational and research facilities, libraries, government agencies, and offices worldwide. Courtesy copies are provided for those participating directly in meteorological support activities such as the Voluntary Observing Ships (VOS) program. For all others, the VOS program offers the MWL in an on-line "webazine" format or hard copy subscriptions can be obtained from the Government Printing Office (GPO).
