International Celestial Reference System (ICRS) - ICRS is the fundamental celestial reference system adopted by the International Astronomical Union (IAU) for high-precision positional astronomy. The ICRS, with its origin at the solar system barycenter and "space fixed" axis directions, is meant to represent the most appropriate coordinate system for expressing reference data on the positions and motions of celestial objects.
ChartCo MetManager - Using the same ChartCo system and software already fitted on many commercial vessels for the receipt of critical chart correction information, the ChartCo MetManager service provides comprehensive weather information and computer-based onboard vessel routing advice.
Coastal Data Information Program (CDIP) - Measures, analyzes, archives, and disseminates coastal environment data for use by coastal engineers, planners, and managers as well as scientists and mariners.
European Centre for Medium Range Weather Forecasts (ECMWF) - An independent international organisation supported by 30 States. Developments numerical methods for medium-range weather forecasting; prepares medium-range weather forecasts for distribution to the meteorological services of the Member States; conducts scientific and technical research directed at the improvement of these forecasts; collects and stores meteorological data
Global Maritime Distress and Safety System (GMDSS) - Provides emergency and safety communications and disseminates Maritime Safety Information (MSI) to all ships on the world's oceans regardless of location or atmospheric conditions. MSI includes navigational warnings, meteorological warnings and forecasts, and other urgent safety related information. The National Weather Service participates directly in the GMDSS by preparing meteorological forecasts and warnings for broadcast via NAVTEX and SafetyNET.
INMARSAT-C SafetyNET - An internationally adopted, automated satellite system for promulgating weather forecasts and warnings, marine navigational warnings and other safety related information to all types of vessels and is part of the Global Maritime Distress and Safety System (GMDSS). There are no user fees associated with receiving SafetyNET broadcasts.
Jenifer Clark's Gulfstream - Using infrared imagery, satellite altimetry data, and surface isotherm data, oceanographic analyses are produced and available for the Gulf Stream area and all the major currents of the world.
Marine Weather - Dedicated to supplying the best and most complete marine weather possible.
MeteoGroup: Ship Performance Optimisation System (SPOS) Onboard - SPOS is the world's leading onboard routing system. SPOS has proven to be an accurate and reliable weather routing system and its high quality weather updates ensure the crew is aware of the weather ahead. With SPOS the ship's route can be optimised onboard, taking into account wind, waves, swell, current and other elements.
National Oceanic and Atmospheric Administration (NOAA) - An organization of the Department of Commerce, NOAA is comprised of the National Ocean Service, National Weather Service, National Marine Fisheries Service, National Environmental Satellite Data, and Information Service, and Office of Oceanic and Atmospheric Research.
NAVTEX - An international automated medium frequency (518 kHz) direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent marine safety information to ships. It was developed to provide a low-cost, simple, and automated means of receiving this information aboard ships at sea within approximately 200 nautical miles of shore. NAVTEX stations in the U.S. are operated by the U.S. Coast Guard. There are no user fees associated with receiving NAVTEX broadcasts.
NOAAWatch - A Web portal offering information about ongoing environmental events, and explains the role of NOAA in prediction, monitoring, and recovery from environmental hazards. It provides public access to current information on a number of environmental threats ranging from oil spills, to hurricanes and tsunamis, to space weather. Provides information about severe weather warnings across the US mainland and coastline. You can access the latest satellite imagery, storm, hydrometeorological and climate prediction centres.
Ocean Prediction Center - Component of the National Centers for Environmental Prediction (NCEP) whose responsibility is the issuance of marine warnings, forecasts, and guidance in text and graphical format for maritime users.
Storm Prediction Center (SPC) - Part of the National Weather Service (NWS) and the National Centers for Environmental Prediction (NCEP). SPC provides timely and accurate forecasts and watches for severe thunderstorms and tornadoes over the contiguous U.S.
Tides & Currents (CO-OPS) - The Center for Operational Oceanographic Products and Services (CO-OPS) collects, analyzes and distributes historical and real-time observations and predictions of water levels, coastal currents and other meteorological and oceanographic data.
Tide Tables - NOAA tide station data and graphs. Predictions of the oceans tides along United States coastal shores, rivers and harbors. Usually listed are tide peak times and levels and current direction, speed and strength. Sunrises, sunsets, moonrises, moonsets and moonphases are often included along with expected tidal data.
WWW Tide and Current Predictor - Select a region here, then from that page, select a site for which to generate predictions. You will get basic predictions and a form for customized predictions.
