Chapter A7. Section 7.1. Fecal indicator bacteria
Donna N. Myers, Marc A. Sylvester
2014, Techniques of Water-Resources Investigations 09-A7.1
Fecal indicator bacteria are used to assess the microbiological quality of water because, although not typically disease causing, they are correlated with the presence of several waterborne disease-causing organisms. The concentration of indicator bacteria is a measure of water safety for body-contact recreation or for consumption. This report provides information...

A one-dimensional diffusion analogy model for estimation of tide heights in selected tidal marshes in Connecticut
David M. Bjerklie, Kevin O’Brien, Ron Rozsa
2013, Scientific Investigations Report 2013-5076
A one-dimensional diffusion analogy model for estimating tide heights in coastal marshes was developed and calibrated by using data from previous tidal-marsh studies. The method is simpler to use than other one- and two-dimensional hydrodynamic models because it does not require marsh depth and tidal prism information; however, the one-dimensional...
Data entry module and manuals for the Land Treatment Digital Library
Justin L. Welty, David S. Pilliod
2013, Data Series 749
Across the country, public land managers make decisions each year that influence landscapes and ecosystems within their jurisdictions. Many of these decisions involve vegetation manipulations, which often are referred to as land treatments. These treatments include removal or alteration of plant biomass, seeding of burned areas, application of herbicides, and...

Tyler Wagner, Jefferson T. Deweber, Jason Detar, John A. Sweka
2013, Transactions of the American Fisheries Society (142) 353-361
Predicting the distribution of native stream fishes is fundamental to the management and conservation of many species. Modeling species distributions often consists of quantifying relationships between species occurrence and abundance data at known locations with environmental data at those locations. However, it is well documented that native stream fish distributions...

2013, ISPRS Journal of Photogrammetry and Remote Sensing (81) 60-69
Lake resources can be negatively affected by environmental stressors originating from multiple sources and different spatial scales. Shoreline development, in particular, can negatively affect lake resources through decline in habitat quality, physical disturbance, and impacts on fisheries. The development of remote sensing techniques that efficiently characterize shoreline development in a...

Jeffrey Obelcz, Daniel S. Brothers, Jason D. Chaytor, Uri S. ten Brink, Steve W. Ross, Sandra Brooke
2013, Deep-Sea Research Part II: Topical Studies in Oceanography (104) 106-119
Shelf-sourced submarine canyons are common features of continental margins and are fundamental to deep-sea sedimentary systems. Despite their geomorphic and geologic significance, relatively few passive margin shelf-breaching canyons worldwide have been mapped using modern geophysical methods. Between 2007 and 2012 a series of geophysical surveys was conducted across four major...

Otto Alvarez, Qinghua Guo, Robert C. Klinger, Wenkai Li, Paul Doherty
2013, International Journal of Climatology (34) 2258-2268
Climate models may be limited in their inferential use if they cannot be locally validated or do not account for spatial uncertainty. Much of the focus has gone into determining which interpolation method is best suited for creating gridded climate surfaces, which often a covariate such as elevation (Digital Elevation...
