- Nautical Charts - National Oceanic and Atmospheric Administration
NOAA ENCs are vector data sets that support all types of marine navigation They hold all of the navigational information associated with traditional nautical charts, while also facilitating real-time ship positioning and helping with collision and grounding avoidance
- Marine Navigation
Our goal is to make this information easily accessible and readily available in internationally recognized navigation standards, such as S-100 Doing so will provide support to mariners throughout every step of a voyage
- About Marine Navigation
For large vessels entering a port — when space is tight and time is critical — mariners anticipate ocean and weather conditions by using observations, forecasts, and underlying foundational data in addition to nautical charts
- Real-Time Observations
Information on where to find real-time observations for each of the primary marine weather and oceanographic variables is given below, along with detailed descriptions of the various observing networks and programs
- Forecasts and Predictions - National Oceanic and Atmospheric Administration
Mariners rely on NOAA’s National Weather Service (NWS) marine weather forecasts, along with tidal predictions and forecast guidance from NOAA’s weather, wave, and ocean circulation forecast models, for safe and efficient marine navigation
- Marine Weather Warnings
Marine Weather Warnings NOAA’s National Weather Service (NWS) issues marine weather watches, advisories, and warnings for hazardous winds and sea conditions
- Nautical Publications
The US Notice to Mariners (NM) provides timely marine safety information for the correction of all U S Government navigation charts and publications from a wide variety of sources, both foreign and domestic
- Marine Navigation Warnings
Marine Navigational Warnings are issued by the U S National Geospatial-Intelligence Agency (NGA) to provide information about persons in distress, or objects and events that pose an immediate hazard to navigation and safety of life at sea across the world
