	abstract = {The Dynamic Digital Map of Selected Sedimentary Rocks in Western Massachusetts (DDM-SedRxWMa) is an example of what can be developed for all National Park Administered land. On starting the program, the user chooses the media source: either "Web-Access" (from a server) or "Local Access" (from DVD, flash or disk drive) and immediately sees a "Home Screen". The Home Screen displays the location of five detailed maps and buttons linked to Indexes (lists) of DDM content. Each map contains numbered icons that link that location to a field guide of that site. Camera icons on the detailed maps point in the direction photos were taken; many photos are oblique aerials that place the map features in context. The aerials contain camera icons of ground photos along the field trip route. The maps can be toggled between an orthophoto map or a topographic map, each geo-referenced. Key field guide locations have 360-degree QuickTime panoramics. All images and movies have captions. The DDM-SedRxWMa program is made from the DDM-Template and is capable of displaying text (captions or field guides) at 3 different user-selectable levels. The text might instead be displayed in 3 different languages. The DDM-SedRxWMa, which includes a 7 minute automated guided tour, can be downloaded at http://ddm.geo.umass.edu/ddm-sedrxwma/ The DDM-Template is an open source program that anyone can use to make their own DDM. It and a step-by-step manual (the "Cookbook") are available along with over 20 DDMs at http://ddm.geo.umass.edu). Making a DDM from the Template requires the use of the relatively inexpensive and easy to learn, multi-platform programming environment Runtime Revolution (www.runrev.com). Maps and photos (jpeg files) and movies are stored outside the program, which acts as an organizational framework and index to present it. Text and data are saved within the program and can be imported from html, rtf or txt format files. Map unit labels, sample sites, and graphics, such as camera icons (created in the Template) can be overlain on the maps or images; and provide a link to view the associated data or images. Once the Template has been modified and renamed, a single step creates 3 royalty-free, stand-alone programs, one each for Unix, Windows and Macintosh operating systems. A DDM program matching the user{\textquoteright}s operating system can be made available online.},

	abstract = {Aquifers located in isolated stratified drift deposits in the northeastern portion of the US are extremely fragile and important groundwater resources. These aquifers, when restricted to bedrock valleys, are often strongly coupled to significant surface water drainage systems. In northwestern Massachusetts, surface water associated with the Deerfield River watershed is highly regulated by dams to protect against flooding and to generate hydroelectric power. Regular releases of water from these dams cause diurnal fluctuations in river stage. In a previous study performed by the USGS, measurements from two clusters of wells show a significant response to river stage fluctuations in the aquifer. Fluctuations in river stage and resulting changes in head levels in the aquifer cause a switch from a losing to a gaining stream. The flow reversals have implications for mass transport and nutrient cycling within the hyporheic zone. In this paper we investigate the physical hydrologic controls on mass transport in the shallow aquifer. Using a coupled groundwater flow and transport code, we built a quasi three dimensional transient numerical model to approximate the head changes in the aquifer caused by the stage fluctuations in the river. Flow velocities and residence times were estimated in the aquifer for a variety of flow conditions. The mixing process driven by the aquifer head changes were quantified in the proximity of the hyporheic zone and shown to significantly influence both vertical and horizontal flow velocities in a region close to the stream-aquifer boundary. The diurnal river stage changes also appear to influence farfield hydrologic conditions and potentially hydrologically isolate the river and hyporheic zone. To further investigate these mixing processes we applied a mass transport code with conservative tracers to the aquifer. Fluctuation of the river stage combined with the heterogeneous nature of the aquifer creates a pumping mechanism that creates excess mixing within shallow portions of the aquifer. Aquifer dispersivity and molecular diffusion both contribute to the anomalous mixing modeled in the shallow aquifer. Mixing driven by stream stage changes has important implications for nutrient cycling as well as contaminant transport in the shallow aquifer.},

	abstract = {<em>(GSA Special Paper)</em> In New England, earthquakes pose a risk to the built environment. Emergency preparedness and mitigation planning are prudent in this region as older unreinforced masonry buildings and numerous critical facilities are common. New England state geological surveys cooperate with the Northeast States Emergency Consortium (NESEC) to improve risk communication with emergency managers. To that end, Connecticut, Maine, Massachusetts, and Vermont employed surficial geologic maps, deglaciation history, knowledge of the glacial stratigraphy, and professional judgment to reclassify surficial geologic material units into one of the five National Earthquake Hazards Reduction Program (NEHRP) site classifications (A, B, C, D, and E). These new classifications were used as a substitute for the HAZards U.S. Multi-Hazard (HAZUS-MH) site class value of "D," which is used throughout New England as a default value. In addition, coding of surficial geologic materials for the five NEHRP site classifications was compared with classifications using the Wald methodology, a method that uses a slope analysis as a proxy for shear-wave velocity estimates. Comparisons show that coding to site classes using the Wald methodology underestimates categories A (high-velocity shear-wave materials, least relative hazard) and E (lowest-velocity shear-wave materials, greatest relative hazard) when evaluated side by side with coding done with the aid of surficial geologic maps. North of the glacial limit, derangement of drainage resulted in extensive ponding of meltwaters and the subsequent deposition of thick sequences of lacustrine mud. Inundation by the sea immediately following deglaciation in New England resulted in the deposition of spatially extensive and locally thick sequences of glacial marine mud. Surficial geologic maps better capture this circumstance when compared with the Wald topographic slope analysis. Without the use of surficial geologic maps, significant areas of New England will be incorrectly classified as being more stable than the site conditions that actually exist. By employing surficial geologic information, we project an improved accuracy for HAZUS-MH earthquake loss estimations, providing local and regional emergency managers with more accurate information for locating and prioritizing earthquake planning, preparedness, and mitigation projects to reduce future losses.},
