	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 = {During the late Pleistocene the Merrimack River paleodelta formed as post-glacial rebound produced a local low stand in sea level. Drowned as sea level rose, the paleodelta is now being reworked by a variety of processes. This study uses benthic foraminifera as a biotic and environmental proxy to study the sand and gravel resources of the paleodelta. Nineteen sediment samples were collected from the paleodelta along two east-west transects east of the Merrimack River. From these samples nearly 6000 benthic foraminifera, representing 62 species, were collected and identified. Although dissolution compromised the preservation of calcite tests within six samples, the resulting data is robust and allows for numerous conclusions to be drawn. Specifically, benthic foraminifera become more common distally and specific species inhabit specific areas of the paleodelta. Distribution patterns of some species have changed significantly since the late 1940s, with some species migrating landward, others, seaward. Distributions of some taxa differ significantly between the two transects, both in the present day and from the past. These differences may point to the influence of, and changes in, the Merrimack River outflow upon water column nutrient delivery, productivity and food availability over the past 60 years. Species diversity and evenness peak at the delta break, coincident with low species dominance at 50 meters water depth. Q-mode cluster analyses show three distinct assemblages, "shallow" (< or =30 meters water depth), "deep" (> or =40 meters), and "delta edge" (50 meters). There is no apparent correlation between foraminiferal distributions and deltaic bedforms, and in turn, sediment type. This implies that foraminiferal distributions are controlled by other environmental variables such as food. In summary, benthic foraminiferal assemblage analyses complement geophysical techniques. Benthic foraminifera can also help assess the marine impact of, e.g., mining sediment resources, watershed development, pollution, rising sea level, and increased fishing.},
