World-Wide Navigational Warning Service

NAVAREA V

Coordinated by Brazil (Brazilian Navy Directorate of Hydrography and Navigation); covers the western South Atlantic off Brazil.

NAVAREA V covers the Atlantic off Brazil, from the equator southward. The Brazilian Navy coordinates it. Offshore oil production in the Campos and Santos basins, survey work and buoys and lights along the long Brazilian coast generate many of its warnings.

seahazards does not read Brazil's own list; NAVAREA V warnings appear here as NGA HYDROLANT relays that name the area as their source.

What the archive shows

16,309 warnings in this archive are attributed to NAVAREA V, issued from 1999-05-15 to 2024-05-08. None of them is in force in the latest lists we collected.

All of them are NGA relays (HYDROLANT, HYDROPAC or HYDROARC) that name NAVAREA V as their source; the area's own list is not in this archive.

Cable ops accounts for 6,245 of 16,309 recorded messages (38%), the largest warning type group in this selection.

The stations and services named as originators most often are NAVAREA V S (2,042), NAVAREA V E (1,527), NAVAREA V SAR (1,429) and NAVAREA V COASTAL S (1,090), among 47 in all.

The largest yearly count is 2000, with 1,626 warnings. Collection is incomplete between 2024-05 and 2026-08-17, so those years are not comparable.

They reached this archive through HYDROLANT (16,305) and HYDROPAC (4).
