2013 Delaware Geological Survey Data Preservation Proposal

Project Contact(s):

The Delaware Geological Survey has submitted a grant proposal for National Geological and Geophysical Data Preservation Program (NGGDPP) funds to preserve our well schedules and outcrop records by converting the paper records to digital PDF files. This NGGDPP grant request will be the first step in making these invaluable records and data available to our stakeholders via the internet. In order to ensure that the research is objective, the data must be preserved and retrievable for both DGS researchers and for stakeholders that wish to review or use the data. Once scanned and filed digitally, these records can be organized in a database with a web application front end to make them searchable and downloadable.

The Determination of Total Nutrient Loads from the Nanticoke Watershed above the USGS Nanticoke at Bridgeville Gauging Site (USGS 01487000) from Data Provided by an Automated Nutrient Analyzer (Greenspan, Aqualab)

Lab close-up
Project Contact(s):

An automated, on-site laboratory collects and analyzes water samples for a collaborative project between the College of Earth, Ocean, and Environment, DGS, DNREC, and USGS.

Delaware Geologic Information Resource (DGIR) Map Viewer

DGIR Map Viewer Screenshot
Project Contact(s):

The Delaware Geologic Information Resource (DGIR) is an online data display tool and map viewer for a variety of geologic and hydrologic information released by the Delaware Geological Survey. It was designed to deliver the most commonly available and requested geologic and hydrologic information that is appropriate for use in hydrologic studies, required by regulation and ordinance, and to support state resource management decisions.

United States Geoscience Information Network (USGIN)

United States Geoscience Information Network (USGIN)
Project Contact(s):

The United States Geoscience Information Network (USGIN) initiative is the product of a partnership between the Association of American State Geologists (AASG) and the United States Geological Survey (USGS) created to facilitate discovery of, and access to, geoscience information provided by state and federal geological surveys of the United States. DGS has entered into a partnership with the Arizona Geological Survey (AZGS) to participate in USGIN by establishing a metadata clearinghouse node for Delaware.

Mapping Tsunami Inundation for the U.S. East Coast

National Tsunami Hazard Mitigation Program
Project Contact(s):

This project will assess tsunami hazard from the above mentioned and other relevant tsunami sources recently studied in the literature and model the corresponding tsunami inundation in affected US East coast communities. We will combine ocean scale simulations of transoceanic tsunami sources, such as Lisbon 1755 like or Puerto Rico Trench co-seismic events, and CVV collapse, with regional scale simulations of these events, along with the regional scale SMF events, in order to establish the relative degree of hazards for East Coast communities. Detailed inundation studies will be conducted for highest-risk East Coast communities, and results of these studies will be used to construct a first-generation of tsunami inundation maps for the chosen communities.

Delaware Groundwater Monitoring Network

Project Contact(s):

The Delaware Geological Survey (DGS) currently monitors groundwater levels in a network of 68 wells in Delaware. Long time-series of water levels in major aquifers serve as critical baseline data for resource management and analyses of aquifer response to pumping, climatic variability, drought hazards, seawater intrusion, and interaction with streams and their ecosystems.

Delaware Geologic Mapping Program (STATEMAP)

STATEMAP Status Map
Project Contact(s):

The Delaware Geological Survey has a continuing program to map the geology of the entire state at the detailed scale of 1:24,000. The STATEMAP component of the National Cooperative Geologic Mapping Program has contributed significantly to our surficial geologic mapping program. This work has entailed not only new geologic mapping, but also the digital compilation of previous mapping. Products resulting from this program include file formats that can be downloaded and printed from the web as geologic map products and imported into GIS software as georeferenced layers.

Temporal Imaging of the Intertidal Critical Zone

Time series of thermal images showing increasing temperature (yellow, orange, and red) as warm tidal water flows over a saltmarsh near Bowers Beach, Delaware during a summer evening (June 2009).
Project Contact(s):

We are developing an innovative ground-based imaging system to collect multi-spectral imagery (visible, near and thermal infrared bands) at time-scales (minutes/hours) below those of the dominant processes in intertidal environments (semi-diurnal tides, day/night). A modular system based on mature imaging technology is being assembled for science missions by foot, boat, truck, tower, and lift. This project consists of some critical laboratory studies to test our conceptual framework.

Web-Delivered Application for Hydrogeologic Data

Project Contact(s):

This project is designed to deliver, by web-based technologies, the most commonly available and requested geologic and hydrologic information used in hydrologic studies required by regulation and ordinance and used by state agencies to support resource-management decisions. Available information can be associated with points or areas. Information associated with points includes descriptive logs, geophysical logs, raw and interpreted groundwater levels, aquifer and geologic unit identification, and hydraulic characteristics of wells. Information associated with areas is either in the form of raster-based (grid) data or polygons. Examples of raster-based data include water-table depths and elevations, tops and thicknesses of geologic and aquifer units, and aquifer transmissivity. Examples of polygons include surficial geology and groundwater recharge potential.

The intent of developing a web-technology enabled system is to provide a more intuitive and comprehensive toolset for locating, quickly viewing, and downloading the desired information in an efficient, extensible, and familiar manner.

A Coastal Flood Monitoring System for Delaware

Flooding at Kitts Hummock after the Mother's Day Storm 2008
Project Contact(s):

During the last two decades, storms such as Hurricanes Katrina and Ike along the Gulf of Mexico and Floyd and Hugo along the Atlantic Coast of the United States have resulted in significant loss of life, injuries, and property damages exceeding well over 100 billion dollars. Much of the damage associated with these and other tropical and extra-tropical weather systems is associated with severe coastal flooding. The purpose of this project is to develop a real-time coastal flood monitoring and warning system for the coastal communities in Kent County, Delaware. This system will serve as a prototype for similar early-warning systems, which may then be applied along the entire Delaware coast.
