To provide tabular data on the trends of chlorophyll-a concentration on a pixel by pixel basis for identifying areas with improving, declining, and stable coastal water quality that can provide guidance for decision making in the context of coastal management.

To provide a gridded version of existing SeaWiFS data in GIS-compatible formats in order to determine concentrations of chlorophyll-a in the coastal water column and to facilitate the integration with other data.

To provide data that can assist in the extraction and analysis of chlorophyll-a concentration and trends from global grids.

To provide documentation on roads data sets that are potential candidates for inclusion in the Global Roads Open Access Data Set (gROADS), and which may be useful to others searching for data on road infrastructure.

To provide a gridded version of existing vector maps of amphibian species distribution in which each grid cell is recoded to 1 (for present) or 0 (for not present) for use in modeling efforts.

To provide a gridded version of existing vector maps of amphibian species distribution at 1- kilometer that preserves the original coding (1=Extant, 2= Possibly present, 3=Probably extinct, 4=Extinct, 5=Extirpated purposely, 6=Occurs on indicated island chain, and 7=Subfossil/fossil).

To provide information on the number of amphibian species present at a 1 kilometer spatial resolution which can be used in modeling efforts, wildlife conservation planning, natural resource management, policy-making, biodiversity studies and human-environment interactions.
