A simple method for in situ monitoring of water temperature in substrates used by spawning salmonids
Christian E. Zimmerman, James E. Finn
2012, Journal of Fish and Wildlife Management (3) 288-295
Interstitial water temperature within spawning habitats of salmonids may differ from surface-water temperature depending on intragravel flow paths, geomorphic setting, or presence of groundwater. Because survival and developmental timing of salmon are partly controlled by temperature, monitoring temperature within gravels used by spawning salmonids is required to adequately describe the...
Characterizing post-drainage succession in Thermokarst Lake Basins on the Seward Peninsula, Alaska with TerraSAR-X Backscatter and Landsat-based NDVI data
Prajna Regmi, Guido Grosse, Miriam C. Jones, Benjamin M. Jones, Katey Walter Anthony
2012, Remote Sensing (4) 3741-3765
Drained thermokarst lake basins accumulate significant amounts of soil organic carbon in the form of peat, which is of interest to understanding carbon cycling and climate change feedbacks associated with thermokarst in the Arctic. Remote sensing is a tool useful for understanding temporal and spatial dynamics of drained basins. In...

Barry P. Baldigo, Brian T. Duffy, Christopher J. Nally, Anthony M. David
2012, Journal of Great Lakes Research (38) 812-820
In 1972, the US and Canada committed to restore the chemical, physical, and biological integrity of the Great Lakes Ecosystem under the first Great Lakes Water Quality Agreement. During subsequent amendments, part of the St. Lawrence River at Massena NY, and segments of three tributaries, were designated as one Area...
A multi-sensor lidar, multi-spectral and multi-angular approach for mapping canopy height in boreal forest regions
David J. Selkowitz, Gordon Green, Birgit E. Peterson, Bruce Wylie
2012, Remote Sensing of Environment (121) 458-471
Spatially explicit representations of vegetation canopy height over large regions are necessary for a wide variety of inventory, monitoring, and modeling activities. Although airborne lidar data has been successfully used to develop vegetation canopy height maps in many regions, for vast, sparsely populated regions such as the boreal forest biome,...
Hydrostratigraphic interpretation of test-hole and surface geophysical data, Elkhorn and Loup River Basins, Nebraska, 2008 to 2011
Christopher M. Hobza, Paul A. Bedrosian, Benjamin R. Bloss
2012, Open-File Report 2012-1227
The Elkhorn-Loup Model (ELM) was begun in 2006 to understand the effect of various groundwater-management scenarios on surface-water resources. During phase one of the ELM study, a lack of subsurface geological information was identified as a data gap. Test holes drilled to the base of the aquifer in the ELM...
Soil data for a collapse-scar bog chronosequence in Koyukuk Flats National Wildlife Refuge, Alaska, 2008
Jonathan A. O’Donnell, Jennifer W. Harden, Kristen L. Manies, M. Torre Jorgenson
2012, Open-File Report 2012-1230
Peatlands in the northern permafrost region store large amounts of organic carbon, most of which is currently stored in frozen peat deposits. Recent warming at high-latitudes has accelerated permafrost thaw in peatlands, which will likely result in the loss of soil organic carbon from previously frozen peat deposits to the...
Peat accumulation in drained thermokarst lake basins in continuous, ice-rich permafrost, northern Seward Peninsula, Alaska
Miriam C. Jones, Guido Grosse, Benjamin M. Jones, Katey Walter Anthony
2012, Journal of Geophysical Research G: Biogeosciences (117) G00M07
Thermokarst lakes and peat-accumulating drained lake basins cover a substantial portion of Arctic lowland landscapes, yet the role of thermokarst lake drainage and ensuing peat formation in landscape-scale carbon (C) budgets remains understudied. Here we use measurements of terrestrial peat thickness, bulk density, organic matter content, and basal radiocarbon age...

Slope-Area Computation Program Graphical User Interface 1.0—A Preprocessing and Postprocessing Tool for Estimating Peak Flood Discharge Using the Slope-Area Method
D. Nathan Bradley
2012, Fact Sheet 2012-3112
The slope-area method is a technique for estimating the peak discharge of a flood after the water has receded (Dalrymple and Benson, 1967). This type of discharge estimate is called an “indirect measurement” because it relies on evidence left behind by the flood, such as high-water marks (HWMs) on trees...
Application of empirical predictive modeling using conventional and alternative fecal indicator bacteria in eastern North Carolina waters
Raul Gonzalez, Kathleen E. Conn, Joey Crosswell, Rachel Noble
2012, Water Research (46) 5871-5882
Coastal and estuarine waters are the site of intense anthropogenic influence with concomitant use for recreation and seafood harvesting. Therefore, coastal and estuarine water quality has a direct impact on human health. In eastern North Carolina (NC) there are over 240 recreational and 1025 shellfish harvesting water quality monitoring sites...

Joshua L. McCormick, Michael C. Quist, Daniel J. Schill
2012, North American Journal of Fisheries Management (32) 1090-1101
Roving–roving and roving–access creel surveys are the primary techniques used to obtain information on harvest of Chinook salmon Oncorhynchus tshawytscha in Idaho sport fisheries. Once interviews are conducted using roving–roving or roving–access survey designs, mean catch rate can be estimated with the ratio-of-means (ROM) estimator, the mean-of-ratios (MOR) estimator, or...

Soil-water dynamics and unsaturated storage during snowmelt following wildfire
Brian A. Ebel, E.S. Hinckley, Deborah A. Martin
2012, Hydrology and Earth System Sciences (16) 1401-1417
Many forested watersheds with a substantial fraction of precipitation delivered as snow have the potential for landscape disturbance by wildfire. Little is known about the immediate effects of wildfire on snowmelt and near-surface hydrologic responses, including soil-water storage. Montane systems at the rain-snow transition have soil-water dynamics that are further...
