  Worldwide seabed sediment map - pack

The “World Seabed Sediment Map” product contains geo-referenced digital data, describing the nature of the sediment encountered in different seas and oceans of the world. The objects are all surface areas and the description of an object includes in particular the nature of the sediment including rock-type bottoms.

Statement

The information used for the development of this product is based on the nature map of the ocean floor published by UNESCO in 1972 and digitized by the Shom in 1995. The purpose of this initial rather coarse map was to provide basic information on to the nature of the seabed and mainly concerned the deep sea. It was gradually improved by the Shom which incorporated more precise maps produced by the Shom, digitized sedimentary maps or summary documents published by various organizations. These maps were previously edited and put into the format of the classification of the nature of the sediments established by the Shom. This version of the world map includes the maps listed in appendix 7.3. These maps were only integrated into the world map when the following conditions were met: - their quality and the interest of their content authorized their integration and validation in the Shom Sedimentological Database (BDSS); - their scale is less than or equal to 1 / 100,000. The product was developed from sedimentary maps identified, digitized and integrated into the BDSS from 1992 to 2020. Some of these maps are synthesis of maps which are themselves derived from the synthesis of very diverse sedimentary data. Many of these compilations were produced by the Shom. The compilation of all these maps in a single document required redefinitions of the overlap zones which were carried out from the data of the morphology and the knowledge of the regional sedimentology (bibliographic and cartographic data).
