Short Description

Example data layer:
Mud areas of the Adriatic Seafloor.

Statement: dbSEABED describes the materials and features of the global seafloor.

Abstract: dbSEABED is a Database/GIS that deals with the materials and features of the seabed. It holds data describing about 2 million seafloor sites. dbSEABED deals with the grain size textures, strengths and porosities, carbon and carbonate compositions, colors, structural features, and grain components of the seafloor. The scope of dbSEABED is global, from shoreline and continental shelf to the abyssal floor, addressing terrigenous-, volcanic- and biogenic-derived materials in their rock and sediment forms. This site publishes gridded outputs suitable for use by numerical modellers.

 {{Data description
 |One-line data description=dbSEABED describes the materials and features of the global seafloor.
-|Extended data description=dbSEABED is an integration of all the  datasets that deal with the materials and features of the seabed. It holds data describing about 2 million seafloor sites, and integrates that pointwise data using an Information Processing System that has a number of processing steps and options. A unique and advantageous feature is that word-based descriptive data about seafloor bottom type is parsed and brought into conformance with the analytical numeric data type, so that they become co-mappable. This gives the best possible geographic coverage and information richness from the available data.

-dbSEABED deals with the grain size textures, strengths and porosities, carbon and carbonate compositions, colors, structural features, and grain components of the seafloor. The diverse inputs on these properties from thousands of individual datasets are harmonized into a standardized and calibrated set of outputs, which initially is pointwise but then is computed into grids and other visualizations. For quality assurance reasons, a significant amount (about 20%) of the original data from the diverse input datasets are not accepted to outputs.
+This site publishes gridded outputs suitable for use by numerical modellers.
-The scope of dbSEABED is worldwide, from estuaries across the continental shelves to the very deepest ocean, dealing with the rock and sediment, and the terrigenous-, volcanic- and biogenic-derived materials. The data are sourced from public domain and collaborative datasets, from all the fields of science, survey, engineering and commerce.
