Collection of Data from Aquifer Tests and Other Hydraulic Tests of Subsurface Material from Maryland
The collection consists of Excel files describing each aquifer (pump) test, containing raw data, plots, and calculations of hydraulic properties (currently Coastal Plain only) and a list of references associated with the collection. Approximately 262 well locations currently have digital aquifer test data; approximately 345 well locations have hydraulic properties described in a published report. This collection will continue to expand as data from additional wells is acquired. The long-term goal is to incorporate pump test data from non-Coastal Plain provinces/Piedmont of Maryland as well.

This collection consists of about 4,000 photographs, as many film negatives, and an estimated 12,000 slides of tidal shorelines in Maryland. The photographs, most black-and-white, were taken between 1948 and 1977 during periodic surveys of shore erosion at specific sites, or benchmarks, along the Chesapeake Bay, its major tributaries, and the Atlantic coast. The coastal counties included in the surveys were: Anne Arundel, Baltimore, Calvert, Cecil, Charles, Dorchester, Kent, Queen Anne’s, St. Mary’s, Somerset, Talbot, and Worcester Counties. Survey geologists established informal benchmarks at a number of sites along the shoreline in each coastal county, on average about a dozen sites per county. The surveyors...

Collection of Cores and Sediment Grab Samples collected from Maryland Chesapeake Bay and Tributaries
To date, the collection consists of about 4,200 unprocessed, surficial sediment (grab) samples collected by Maryland Geological Survey (MGS) from the bottom of the Maryland Chesapeake Bay and its major subestuaries between 1976-1984, as part of the Chesapeake Bay Earth Science Study (CBESS), a multidisciplinary research effort authorized by Maryland and Virginia through the U.S. Environmental Protection Agency (EPA). MGS collected samples according to two sampling schemes, mid-bay and nearshore, and then processed them to develop a baseline inventory of certain physical and geochemical characteristics of bay bottom sediments, in particular, water content, grain size composition, and carbon and sulfur content. Since...

Unpublished reports, usually associated with a specific project involving Maryland Geological Survey (MGS) staff. Generally, these are file reports or open-file reports that meet the terms of a grant or contract but are not otherwise distributed or included in the MGS List of Publications. They are commonly, but not necessarily, associated with a particular collection(s). Reports, both paper and digital, need to be collected in a central location, organized, catalogued, and archived. Eventually, they should all be digitized/scanned and be made available electronically.
