Carbon Exchange Data - Cypress Swamp Sampling Location (Greater Everglades)

Barclay Shoemaker
This file is an Excel file containing data for the Cypress Swamp sampling location. It includes the following data sheets: -raw_weather - raw data for wind direction, wind gust, incoming solar radiation, soil heat flux, net radiation, air temperature, relative humidity, temperature of air, water and soil, and volumetric water content. -work_weather - mean 30-minute mean calculation for data in raw_weather. This averaging syncs time for weather and eddy covariance data. Wind speed correction for...

Airborne Geophysical Surveys over the 2011 Mineral, Virginia Earthquake Area

Anjana K Shah
The 2011 moment magnitude (Mw) 5.8 central Virginia earthquake was felt by millions of people and caused significant damage in the eastern United States. As part of efforts to better understand the faults and geologic features associated with the earthquake, the U.S. Geological Survey commissioned airborne geophysical surveys over the epicentral area. Here we present the data from those surveys and summarize research results based on those datasets.

Mojave Region Water-Level Study, 2012

Nick F. Teague, Christina L. Stamos, Sally F. House & Dennis A. Clark
Regional water-table maps of the Mojave River and Morongo ground-water basins have been published in reports by the U.S. Geological Survey (USGS) every two years since 1992. The water-level reports for the years 1992-2004 were published as USGS Water-Resources Investigations Reports or Scientific Investigations Reports and are available online as separate Portable Document Fomat (pdf) formatted reports, which can be accessed on the "References" page on this website; the water-level contours from most of the...

Dissolved Gas, Environmental Tracer Concentrations, and Lumped Parameter Modeling Results for Groundwater Age Dating in the Glacial Aquifer System, Conterminous United States

John E Solder
This data release documents nine Microsoft Excel tables that contain data for understanding groundwater ages in the Glacial aquifer system. Results for the three sample networks (PAS, principal aquifer study; MSS, modeling support study; FPS, flow path study) are described by three tables each: dissolved gas modeling results, environmental tracer concentrations (tritium, tritiogenic helium-3, sulfur hexafluoride, carbon-14, and radiogenic helium-4), and results for the mean age and age distribution. Tables are labeled by network and...

High-resolution geophysical and sample data collected in Moultonborough Bay, Lake Winnipesaukee, New Hampshire in 2005, USGS Field Activity 2005-004-FA

Jane F. Denny, William W. Danforth, Charles R. Worley & Barry J. Irwin
In freshwater bodies of New Hampshire, the most problematic aquatic invasive plant species is Myriophyllum heterophyllum or variable leaf water-milfoil. Once established, variable leaf water-milfoil forms dense beds that can alter the limnologic characteristics of a waterbody, impacting natural lacustrine communities and their habitats. Variable leaf water-milfoil infestations also disrupt recreational uses of waterbodies and have negatively affected swimming, boating, fishing, and property values in and around several lakes and ponds in New Hampshire. In...

Avian Point Transect Survey Data, Seward Peninsula, Alaska, 2012

Lance B. McNew & Colleen M. Handel
This data product contains avian point transect survey data and habitat data collected on the Seward Peninsula, Alaska USA during 21 May ? 10 June, 2012. We conducted replicated 10-min surveys at 111 points located along 9 transects occurring over gradients of physical and biotic habitat conditions and recorded observations of individual birds identified to species. Survey points, or sites, were located approximately 500 m apart and observations of birds were limited to a maximum...
