Measurements of milkweeds and associated arthropods at Hastings Preserve, California in 2013
Monthly measurements of milkweed stems were made in 2013 at Hastings Natural History Reservation. At the same time, arthropod communities were measured associated with each milkweed stem. Treatments were conducted in which a subset of milkweed stems were damaged each month.
Peak-flow files and PeakFQ output files for U.S. Geological Survey streamgages in the New England region that were used in regional skew analysis
This data release contains annual peak-flow data and PeakFQ output files for 186 selected streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in the New England region (Maine, Connecticut, Massachusetts, Rhode Island, New York, New Hampshire, and Vermont). The annual peak-flow data were obtained from the USGS National Water Information System (NWIS) database (htt
Data sets for a quantitative dye tracer test conducted at the Savoy Experimental Watershed, November 13-December 2, 2017, Savoy, Arkansas
These are the data sets in machine readable files from a quantitative dye tracer test conducted at Langle Spring November 13-December 2, 2017 as part of the USGS training class, GW2227 Advanced Field Methods in Karst Terrains, held at the Savoy Experimental Watershed, Savoy Arkansas. Langle Spring is NWIS site 71948218, latitude 36.11896886, longitude -94.34548871. One pound of RhodamineWT dye was
MODFLOW-2005 and MODPATH models used to simulate hydraulic tomography pumping tests and identify a fracture network, former Naval Air Warfare Center, West Trenton, NJ
MODFLOW-2005 groundwater flow models were developed to simulate 47 pumping tests conducted for a hydraulic tomography experiment in fractured rocks underlying the former Naval Air Warfare Center, West Trenton, New Jersey. These flow models simulate the change in water level during the pumping tests, which range from about 45 to 60 minutes in duration. MODFLOW-2005 models were also developed to sim
Pumping Rate, Drawdown, and Atmospheric Pressure Data from Hydraulic Tomography Experiment at the Former Naval Air Warfare Center, West Trenton, NJ, 2015-2016
This data release presents pumping rate data, water-level drawdown and recovery data, and atmospheric pressure data collected during 48 pumping tests conducted in 2015 and 2016 for a hydraulic tomography field experiment in the mudstone aquifer underlying the former Naval Air Warfare Center (NAWC), West Trenton, NJ. The pumping rate data include rates measured by in-line flow meters and rates meas
Digital terrain models of Spirit Lake blockage and Mount St. Helens debris avalanche, based on 1980-2018 airborne photogrammetry surveys
The lateral blast, debris avalanche, pyroclastic flows, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. The debris avalanche and pyroclastic flows filled upper North Fork Toutle River valley and blocked the outlet of Spirit Lake. To mitigate the risk of a catastrophic breach, lake outflow was pumped over the blockage prior
Time series data of oceanographic conditions from La Parguera, Puerto Rico, 2017-2018 Coral Reef Circulation and Sediment Dynamics Experiment
Time-series data of water surface elevation, waves, currents, temperature, and salinity collected between 17 May 2017 and 17 Jan 2018 off the southwest coast of Puerto Rico in support of a study on circulation and sediment transport dynamics over coral reefs. The data are available in NetCDF format, grouped together in zip files by instrument site location. A README.txt file details the files cont
Data Release: Upper Klamath Lake, Oregon, Hyperspectral Algal Samples
This data represents samples of algae from Upper Klamath Lake Oregon, during the summer of 2016. Data were sampled from the lake using standard protocols and then shipped to the remote sensing laboratory at the National Institute of Standards and Technology (NIST) for analysis on the hyperspectral microscope at NIST.
Baseline Coastal Oblique Aerial Photographs Collected from the Harney River, Everglades National Park, Florida to Anclote Key, Florida, November 14, 2006
The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards (NACCH) project conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms and longer-term processes related to sediment supply and sea-level rise. On November 14, 2006, the USGS's NACCH project conducted
Grand Liard Marsh and Ridge Restoration (BA-68): 2016 land-water classification
The Louisiana State Legislature created Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coa
Gravity and physical property data in the Chico and Willows 1:100,000-scale quadrangles, California
The datasets consist of principal fact information of gravity data and density and magnetic properties of hand samples in the Chico and Willows 1:100,000-scale quadrangles, California.
AZ Winter Sparrow Transect Survey Data 1999 to 2005
This dataset provides the winter bird transect survey data collected on seven sites in southeastern Arizona during the winters (January - March) of 1999-2001; and for two of those seven sites during the winters of 2003-2005.
