The Output Parameters
The output parameters from dbSEABED are defined in this document.

One-Page Information Sheets
Seabed composition data is complicated. Here are one-page guides to some of the issues and tasks performed in dbSEABED:
The Coastline: Boundary Condition
Numerical Forms for Folk & Domnc Grids
Supporting Environmental Data LeyersCompositional Data Analysis Compliance
Materials Classified as 'Rock'Polygon-to-Point Methods
Land Proximity Data
Standardized GIS Legends
A collection of *.avl and *lyr files which can efficiently be picked up and used in Geographic Information Systems.

It is strongly recommended that labs use these standard schemes - liveries - for quick and accurate visual communication with maps, especially within the dbSEABED community

       - For ArcGIS9.x and ArcView3.x
       - For Quantum GIS (QGIS)

Data Model
The output parameters from dbSEABED are described with a Semantic Web syntax. This is suitable for use with applications like SPARQL.
Random Forests "Painter"
A Random Forests method of expertly extending - painting - gridded results from dbSEABED over vast unmapped regions such as the South Pacific Ocean. While we would prefer that there was more data it is necessary for some projects to give a current 'best estimate' of conditions. RF methods boast very high reliability if a proper technique is used.

Maximum a-Posteriori Resampler
This tool for 'interpolation' of noisy, heterogeneous data was contributed by John Goff of UTIG/UTexas, Austin USA. A paper has been published, describing the tool.
IODP - ODP - DSDP Parameter Sets
For the SEDIS III project the parameter vocabularies of datasets connected with Ocean Drilling were analysed with a view to rationalization and preparation for use with the Semantic Web query techologies.

Interpolator for Marine Substrates
An interpolator suitable for mapping marine substrates (ONR Award). Special measures are taken to: interpolate sensibly near shorelines and through archipelagos, retain the resolution in well-surveyed areas, avoid spatial biases using isotropic data selection, quantify uncertainties, validate the grids with jacknife methods.
GeoMaterials Vocabulary
For the Dark Data (NSF EAGER Award 1242909)  a vocabulary of  lithology, soils, fluids, ice terms was compiled which could help locate and rate 'dark' geoscience datasets from their web presence in metadata or publications. The vocabulary is also useful for reconciling geomaterials terms between land/coast/ocean (NSF RAPID Award 1047776 'Seamless over Strandline').
