In 1874 the current Hydrographic and Oceanographic Service of the Chilean Navy was created, becoming the first cartographic national agency; the first one created in Latin America and No. 12 in the world. The same year it was founded it begins to issue notices to mariners, through the Hydrographic news Bulletin.

        Through the years, the Hydrographic Service has implemented new methodologies, due to a constant concern to provide mariners onboard all the available information that would allow them a safe displacement at sea, with their charts and updated nautical publications. That is how to this date it provides, either national or foreign, war, merchant, fishing or sailing vessels, with cartography and updated nautical publications on the date of their delivery or purchase at a Sale Agency. From that moment, the users of the above-mentioned navigational aids are responsible for incorporating information and corrections produced thereafter and which are spread by SHOA in the “News Bulletin to Mariners”. This Bulletin which is monthly published contains all the information and hydrographic news that have occurred during that period, and it helps to correct the charts and nautical publications used onboard vessels and that are affected by such news. This is very important for navigational safety, because charts and nautical publications are corrected at the moment of its distribution, but many changes that are necessary to consider may occur later on, such as: buoys out of place, turned off, inaugurated or remote lights, new sounding lines, changes in the characteristics of ports, etc.

       Their commitment to provide safety to navigation and optimal quality of service to users of mapping edited by SHOA, it reflects this more than century-old publication, which since October 2003 is available online, its main body, first in html and in PDF. Under continuous improvement, since January 2008, published the main body of the Bulletin Notices to Mariners, and replacement pages involving nautical publications that SHOA edits, for download from the web.
