The Sea Bulletin is an application developed by the Hydrography and Navigation Directorate (DHN), in conjunction with the Mariner's Shelter and the Rumo ao Mar Institute (RUMAR). Available for free for Android and iPhone (iOS), its goal is to make the information already produced by DNH accessible to the maritime community, enabling greater interaction with products created for navigation safety. Through the app, it is possible to view warnings of bad weather, which alert to conditions that may impair navigation.

Through the app, you can access the weather report, which, in addition to the weather forecast, also informs about wind conditions, waves and visibility. The Sea Bulletin also makes it possible to view weather reports, synthetic charts, numerical models prepared by the Marine Weather Service, in addition to Nutricional Radio Warnings and SAR (Search and Rescue). One of the main functions of the application is bad weather warnings, which are warnings issued in advance to avoid situations that may cause problems in navigation.
In addition to bad weather warnings, the Sea Bulletin has functions such as synthetic letters Photo: Sea Bulletin / Disclosure
With the synthetic charts, it is possible to observe the meteorological variables in various layers of the atmosphere. Meteograms, in turn, report pressure, temperature, relative humidity, wind, precipitation and cloudiness. Nutritional Radio Warnings are the urgent messages transmitted to ships, and SAR Radio Warnings correspond to emergency alerts or search and rescue coordination.
All of this information is reliably generated by the Brazilian Navy DNH, and can help anyone wishing to navigate the Brazilian coast, South Atlantic ocean areas and inland waterways (rivers, lakes or lagoons). Thus, the app tends to contribute directly to the activities of hydrography, oceanography, cartography, marine meteorology, navigation and nutritional signaling.
