DGS Cooperative and Joint-Funded Programs

The DGS is, by statute, the state agency responsible for entering into agreements with its counterpart federal agencies, including the U.S. Geological Survey, the USGS Office of Minerals Information (formerly the U.S. Bureau of Mines), and the Bureau of Ocean Energy Management, Regulation and Enforcement (formerly the U. S. Minerals Management Service), and for administering all cooperative programs of the State with these agencies. The DGS also works with many in-state and out-of-state partner agencies and organizations.

The Delaware DataMIL Gets a New Look!

The DataMIL gets a New Look!
Date: Mar 2009

The Delaware DataMIL was redesigned to take advantage of more modern web technologies as well as to answer key feature requests to the system. In particular, new additions to the DataMIL include: complete FGDC metadata for all layers, a map previewer embedded into the metadata catalog, and the ability for all datasets (vector and raster) to downloaded as raw GIS data files as well as ArcIMS and WMS map services

The Mason-Dixon Line, that land is your land

The Mason-Dixon Line, That Land Is Your Land

The Mason-Dixon Line wasn’t created to divide North and South, but to settle a dispute between Colonial landowners. The Mason-Dixon Line, the iconic dividing line between North and South, is an invisible line running across the backyard of many Delawareans. Charles Mason and Jeremiah Dixon’s milestone markers still dot the Maryland-Delaware-Pennsylvania border more than 240 years after they completed their survey.

Delaware Geological Survey Radiocarbon Database

Delaware Geological Survey Radiocarbon Database

Radiocarbon dates from 231 geologic samples from the offshore, coastal, and upland regions of Delaware have been compiled along with their corresponding locations and other supporting data. These data now form the Delaware Geological Survey Radiocarbon Database. The dates range from a few hundred years to approximately 40,000 yrs (40 ka) BP (before present). All dates younger than about 18,000 yrs have been calibrated using the method of Stuiver and Reimer (1993). A plot of the dates versus the elevations of the samples shows four distinct groupings: those associated with the rise of sea level during the Holocene, those from the uplands, those in modem stream valleys, and those older than the detectable range of present radiocarbon techniques. A fifth group of samples in the 20-38 ka range and from below present sea level are ambiguous and were previously used as evidence for a mid-Wisconsinan high sea stand (Milliman and Emery, 1968).
