Parsing in dbSEABED

Numeric data mined from verbal logs, core or grab descriptions, shipboard notes, and photographic descriptions are classified as “parsed” data. Input data are maintained using the terms employed by the original researchers and are coded using phonetically sensible terms for easier processing by...

dbSEABED: Data processing and mining

At the core of usSEABED is dbSEABED, a data-mining program based on the application of fuzzy set theory to marine geological and biological data. Fuzzy set theory allows expansion of coverage of the seafloor by the use of word-based data from core logs, sample descriptions, photos, and videos, as well as the more standard numeric data from a laboratory.

Great Lakes Geologic Mapping Coalition (GLGMC)

The Great Lakes Geologic Mapping Coalition (GLGMC) advances the understanding of the three-dimensional distribution of the glacial, periglacial, and proglacial deposits that overlie the bedrock of the glaciated Midwest. It recognizes the fact that several continental glaciations of the last million years have profoundly...

Water Quality Across Regional Stream Networks: The Influence of Land Cover and Land Use, Climate, and Biogeochemical Processing on Spatiotemporal Variance

Land cover and land use (LC/LU), climate, and biogeochemical processing are significant drivers of water quality in streams and rivers over broad scales of space and time. As LC/LU and climate continue to change we can expect changes in water quality. This project seeks to understand the drivers of spatial and temporal variability in water quality across scales using new and existing data to...
