Identifying materials by measuring and analyzing their reflectance spectra has been an important procedure in analytical chemistry for decades. Airborne and space-based imaging spectrometers allow materials to be mapped across the landscape. With many existing airborne sensors and new satellite-borne sensors planned for the future, robust methods are needed to...

V.A. Cross, J.F. Bratton, John Crusius, K.D. Kroeger, C.R. Worley
2012, Open-File Report 2011-1041
An investigation of coastal groundwater systems was performed along the North Shore of Long Island, New York, during May 2008 to constrain nutrient delivery to Northport Harbor and Manhasset Bay by delineating locations of likely groundwater discharge. The embayments are bounded by steep moraines and are underlain by thick, fine-grained...

John M. Besser, William G. Brumbaugh, Diana M. Papoulias, Chris D. Ivey, James L. Kunz, Mandy Annis, Christopher G. Ingersoll
2012, Scientific Investigations Report 2012-5033
Populations of desert pupfish (Cyprinodon macularius; pupfish), a federally-listed endangered species, inhabit irrigation drains in the Imperial Valley agricultural area of southern California. These drains have varying degrees of selenium (Se) contamination of water, sediment, and aquatic biota. Published Se toxicity studies suggest that these levels of Se contamination may...

Ward E. Sanford, S.C.P. Pearson, K. Kiyosugi, H.L. Lehto, J.A. Saballos, C.B. Connor
2012, Geochemistry, Geophysics, Geosystems (13)
We investigate geologic controls on circulation in the shallow hydrothermal system of Masaya volcano, Nicaragua, and their relationship to surface diffuse degassing. On a local scale (~250 m), relatively impermeable normal faults dipping at ~60° control the flowpath of water vapor and other gases in the vadose zone. These shallow...

2012, Conference Paper, RMRS-P-67
Between 2001 and 2009, the Borderlands Jaguar Detection Project deployed 174 camera traps in the mountains of southern Arizona to record jaguar activity. In addition to jaguars, the motion-activated cameras, placed along known wildlife travel routes, recorded occurrences of ~ 20 other animal species. We examined temporal relationships of white-tailed...
An investigation of submarine groundwater—borne nutrient fluxes to the west Florida shelf and recurrent harmful algal blooms
Christopher G. Smith, Peter W. Swarzenski
2012, Limnology and Oceanography (57) 471-485
A cross‐shelf, water‐column mass balance of radon‐222 (222Rn) provided estimates of submarine groundwater discharge (SGD), which were then used to quantify benthic nutrient fluxes. Surface water and groundwater were collected along a shore‐normal transect that extended from Tampa Bay, Florida, across the Pinellas County peninsula, to the 10‐m isobath in...

The Mississippi River-Gulf Outlet navigation channel (MRGO) was constructed in the early 1960s to provide a safer and shorter route between the Gulf of Mexico and the Port of New Orleans for deep-draft, ocean-going vessels and to promote the economic development of the Port of New Orleans. In 2006, the...
Landsat: a global land imaging program
Raymond A. Byrnes
2012, Fact Sheet 2012-3057
Landsat satellites have continuously acquired space-based images of the Earth's land surface, coastal shallows, and coral reefs across four decades. The Landsat Program, a joint effort of the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA), was established to routinely gather land imagery from space. In...
A framework for inference about carnivore density from unstructured spatial sampling of scat using detector dogs
Craig M. Thompson, J. Andrew Royle, James D. Garner
2012, Journal of Wildlife Management (76) 863-871
Wildlife management often hinges upon an accurate assessment of population density. Although undeniably useful, many of the traditional approaches to density estimation such as visual counts, livetrapping, or mark–recapture suffer from a suite of methodological and analytical weaknesses. Rare, secretive, or highly mobile species exacerbate these problems through the reality...
Feedbacks between inundation, root production, and shoot growth in a rapidly submerging brackish marsh
Matthew L. Kirwan, Glenn R. Guntenspergen
2012, Journal of Ecology (100) 764-770
1. Ecogeomorphic feedbacks between mineral sediment deposition and above-ground plant growth are thought to have dominated the evolution of many coastal ecosystems and landforms. However, land-use-related reductions in sediment delivery rates to estuaries world-wide suggest that these above-ground feedbacks may not apply in some of the world's most vulnerable coastal...
Foraging behavior of Long-tailed Ducks in a ferry wake
Matthew C. Perry
2012, Northeastern Naturalist (19) 135-139
Clangula hyemalis (Long-tailed Ducks) were observed diving in the wake of the Nantucket Island ferry during December over a 5-year period (2005–2009). The unusual diving behavior appeared to be related to foraging, but could not be confirmed. Long-tailed Ducks typically feed on more mobile prey than most other diving ducks,...
