The DGS has begun a multi-year project to install new groundwater monitoring infrastructure and collect baseline data in Sussex County, Delaware. This project is a continuation of a larger effort to construct a statewide groundwater monitoring network.
Geologic maps at the DGS are created as primary deliverables of a project and as derivatives of other projects. Primary deliverables are mainly those that are the result of outside funding sources such as the AASG-USGS cooperative StateMap. Derivative maps are those that have primary data collected for reasons other than geologic mapping can be used to create geologic maps or that geologic maps are derivative products of a project rather than the primary goal of a project.
Amino acid racemization (AAR) geochronology has been applied to Quaternary deposits of the US Atlantic and Pacific coasts for over 40 years (see reviews in Wehmiller, 1992, Wehmiller et al., 1988, Wehmiller and Miller, 2000, and Wehmiller, 2013a, 2013b). In an effort to develop a comprehensive database of results from these various studies, Pellerito (2004) created the MS-Access Database that is part of this open-file publication (see Pellerito citation in reference section). The current version of this database is a work in progress, as information is being updated regularly.
