Short Description
Example data product - Seafloor classification, Northern Gulf of Mexico |
Statement: dbSEABED describes the materials and features of the global seafloor.
Abstract: [[Extended data description::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.
- The project supplies gridded outputs suitable for use in numerical models. The basic set of gridded parameters is: gravel, sand, mud (%), rock exposure (%), average grainsize and sorting (phi), carbonate (%). A specification of the parameters is given in the usSEABED web pages. dbSEABED uses the Wentworth grain size classification and scale.
A collection of ESRI ArcView 3.x and ArcGIS 9.x legends to this standard is available from this web address: GIS Legends. The format for delivery of gridded data from dbSEABED is the E.S.R.I. ASCII grid format, at finest 0.02 degrees cell size, with WGS 84 datums. The grid extents are grid-centred, i.e. ArcView 3.x format.
