Marotiri - îlot Sud
Marotiri is a group of four uninhabited volcanic rocks protruding from the sea (and several submerged rocks), forming the southeastern end of the Austral Islands of French Polynesia. Marotiri is also known as Bass Rocks (''Îlots de Bass'' in French), maybe according to the name of the European explorer George Bass. Marotiri is very isolated, located about west-south-westward of Pitcairn Island. The closest island is Rapa Iti, 75 km farther northwest, but separated from it by an ocean depth of more than 1,500 meters.According to the French hydrographic office (SHOM) nautical charts 6607, there is a depth of 1,646 meters midway between Rapa and Marotiri. The rocks are part of the municipality of Rapa. The climate is wet temperate. The lower rocks are almost devoid of vegetation - although there is some vegetation on the upper slopes and summits. They are important as a seabird rookery. Fish abound in the adjacent waters. The rocks emerge from a submarine platform 100 meters ...

Nautical Chart
A nautical chart or hydrographic chart is a graphic representation of a sea region or water body and adjacent coasts or river bank, banks. Depending on the scale (map), scale of the chart, it may show depths of water (bathymetry) and heights of land (topography), natural features of the seabed, details of the coastline, navigational hazards, locations of natural and human-made aids to navigation, information on tides and Ocean current, currents, local details of the Earth's magnetic field, and human-made structures such as harbor, harbours, buildings, and bridges. Nautical charts are essential tools for marine navigation; many countries require vessels, especially commercial ships, to carry them. Nautical charting may take the form of charts printed on paper (raster navigational charts) or computerized electronic navigational charts. Recent technologies have made available paper charts which are printed "on demand" with cartographic data that has been downloaded to the commercial ...

Desert Island
An uninhabited island, desert island, or deserted island, is an island, islet or atoll which lacks permanent human population. Uninhabited islands are often depicted in films or stories about shipwrecked people, and are also used as stereotypes for the idea of "paradise". Some uninhabited islands are protected as nature reserves, and some are privately owned. Devon Island in Canada's far north is the largest uninhabited island in the world. Small coral atolls or islands usually have no source of fresh water, but occasionally a freshwater lens can be reached with a well. Terminology Uninhabited islands are sometimes also called "deserted islands" or "desert islands". In the latter, the adjective ''desert'' connotes not desert climate conditions, but rather "desolate and sparsely occupied or unoccupied". The word ''desert'' has been "formerly applied more widely to any wild, uninhabited region, including forest-land", and it is this archaic meaning that appears in the phrase "d ...

Hydrographic Office
A hydrographic office is an organization which is devoted to acquiring and publishing hydrographic information. Historically, the main tasks of hydrographic offices were the conduction of hydrographic surveys and the publication of nautical charts. In many countries, various navigation-related services are now concentrated in large governmental organizations, sometimes termed "maritime administration" (however, the International Hydrographic Organization uses the term "hydrographic offices" for its member organizations). Besides nautical charts, many hydrographic offices publish a body of books and periodicals that are collectively known as nautical publications. The most important of these are: * Sailing Directions (or ''pilots''): detailed descriptions of areas of the sea, shipping routes, harbours, aids to navigation, regulations etc. * lists of lights: descriptions of lighthouses and lightbouys *tide tables and tidal stream atlases * ephemerides and nautical almanacs for ...
