A methods-oriented page serving multiple projects and applications

This page inventories and links to internet-based tools for assembling and analyzing data relevant to the relationships between environmental and biotic variables. Contents will be expanded as products are developed and links contributed.

Currently Available Tools:

       Geospatial clustering and visualization (LOICZVIEW)
              Information, description, and instructions for use
              Login to application

This robust and flexible k-means clustering tool for high-dimensionality data sets is scale independent, features map-type visualization and comparison of outputs and inputs, and provides output of cluster results and statistical cluster summaries. It is linked to the LOICZ/Hexacoral environmental database (see below), and can also accept independent dataset uploads. Unsupervised and supervised clustering are provided, as are eigenanalyses, overlay comparisons, and cluster merge capability.

LOICZ/Hexacoral environmental database (Envirodata)
       Information, description, and instructions for use
       Login to application

This database of environmental variables relevant to coastal and marine areas provides global information on a half-degree grid. It is designed primarily for typology applications using the LOICZVIEW clustering tool (see above), but is useful for a variety of applications. In addition to permitting clustering or downloading of variables selected by type and geographic range, it contains tools and for filtering, tansforming, and viewing the distributions of the variable values.

Hexacoral taxonomy and distribution (Biodata)
      Login to application

The interface for this database provides a catalogue of species, bibliography of literature in which they were described, inventory of type specimens, distribution maps, and images. An integral feature is the Syngraph database that identifies synonomies and the current status of taxonaomic names.

Areas of Development:

     Biogeographic distribution analysis and prediction will be supported by further development of tools linking the geographic distribution of Hexacorallian taxa with the distribution records of other cooperating projects and the environmental data sets and analytical results. We anticipate cooperative development of biodiversity model and analysis tools (e.g., with "Development of a Biogeographical Information System for Seamounts" NSF DBI-0074498, Karen Stocks, SDSC) as well as descriptive and predictive biogeographic models.
