Application of flood regressions and climate change scenarios to explore estimates of future peak flows

Burns, Douglas A.; Smith, Martyn J.; Freehafer, Douglas A.
A Web-based application, titled Application of Flood Regressions and Climate Change Scenarios To Explore Estimates of Future Peak Flows , has been developed by the U.S. Geological Survey, in cooperation with the New York State Department of Transportation, that allows a user to apply a set of regression equations to estimate the magnitude of future floods for any stream or river in New York State (exclusive of Long Island) and the Lake Champlain Basin in...

Oceanographic and Water-Quality Measurements in Rachel Carson National Wildlife Refuge, Wells, Maine

E.T. Montgomery
This web page provides access to oceanographic, meteorological, and water-quality observations made at four locations in Rachel Carson National Wildlife Refuge in Wells, Maine. The objective was to characterize the sediment-transport mechanisms that contribute to the sediment budget of the wetland complex along the Oguinquit River. A meteorological tower, temperature and conductivity sensors, optical turbidity sensors and acoustic velocity meters were deployed at sites on Stephens Brook and the Ogunquit River between March 27 and...

U.S. Geological Survey researchers conducted time-series ground-penetrating radar (GPR) surveys with a Sensors and Software 500-MHz Pulse Ekko Pro system. This data release contains ground-based (ski and snowmobile) as well as airborne common-offset profiles. All profiles are linked to coincident GPS observations. Additionally, common-midpoint data was collected at specific glacier locations. Coincident in-situ data may provide calibration information, and may be composed of any of the following: snow pits and/or snow-pit/snow-core combinations, probe profiles, and...

Shorelines Extracted from Landsat Imagery: Dauphin Island, Alabama

Kristy K. Guy
Changes to barrier islands occur at time scales that vary from the few hours it takes an individual storm to pass (Morton, 2008) to the millennia it takes for the geologic evolution of coastal systems to take place. Developing an understanding of how barrier islands will respond to climate change, sea level rise, and major storms over a range of time-scales is relevant to studies of physical, geological, ecological, and societal processes and will help...

Oceanographic measurements for characterizing light attenuation and sediment resuspension in the Barnegat Bay- Little Egg Harbor estuary, New Jersey, 2013

P.K. Dickhudt
Light attenuation is a critical parameter governing the ecological function of shallow estuaries. We quantified light attenuation and sediment resuspension in three seagrass meadows in Barnegat Bay, New Jersey, by sequentially deploying instrumentation measuring photosynthetically active radiation, chlorophyll-a (chl-a) fluorescence, dissolved organic matter fluorescence (fDOM; a proxy for colored DOM absorbance), turbidity, pressure, and water velocity at 10 min intervals over three week periods at each site. The data show the relative importance of physical...

LPJ biomes (30-year mean) simulated using monthly historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada, version 1.0

Sarah L. Shafer & Patrick J. Bartlein
This data set consists of biomes (30-year mean) simulated using LPJ, a dynamic global vegetation model (Sitch et al. 2003, Global Change Biology 9:161-185), for a 30-second grid of the northwest United States and southwest Canada. Shafer et al. (2015, PLoS ONE 10: e0138759) describe the methods used to create the biome data.

Sarah L. Shafer & Patrick J. Bartlein
This data set consists of monthly mean temperature (degrees C), total precipitation (mm), and possible sunshine (%) data statistically downscaled onto a 30-second grid of the northwest United States and southwest Canada. Historical climate data for 1901-2000 were developed from the CRU CL 1.0, CRU CL 2.0, and CRU TS 2.1 data sets (http://www.cru.uea.ac.uk/cru/data/hrg/). Projected future climate data for 2001-2099 were developed using climate model simulations produced by five coupled atmosphere-ocean general circulation models: CCSM3,...

High-resolution geophysical data collected along the Delmarva Peninsula 2015, U.S. Geological Survey Field Activity 2015-001-FA

Edward M Sweeney, Elizabeth P Pendleton, Seth Ackerman, Brian D Andrews, Wayne E Baldwin, William W Danforth, David S Foster, E. Robert Thieler & Laura Brothers
The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy in the fall of 2012. The U.S. Geological Survey conducted cruises during the summers of 2014 and 2015 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Geophysical data collected during the cruises include swath...
