Single-Beam Bathymetry Data Collected in 2015 from Grand Bay, Mississippi/Alabama
This data release archives processed single-beam bathymetry (SBB) data, collected from May 28-June 3, 2015 (USGS Field Activity Number 2015-315-FA) within Grand Bay Mississippi/Alabama, as part of the Sea level and Storm Impacts on Estuarine Environments and Shorelines project (SSIEES). The goal of the SSIEES project is to assess the physical controls of sediment and material exchange between wetl
Corallimorph Invasion Palmyra: Data
In 2007, a phase shift from corals to corallimorpharians (CM) was documented at Palmyra Atoll, Line Islands, centered around a shipwreck. Subsequent surveys revealed CM to be overgrowing the reef benthos, including corals and coralline algae, potentially placing coral ecosystems in the atoll at risk. This prompted the U.S. Fish and Wildlife Service, the lead management agency of the atoll, to r
USGS Klamath River Basin Water-Quality Mapper
This map interface represents continuous and discrete water-quality data collected by Bureau of Reclamation and USGS at Klamath Basin sites. The USGS and Reclamation data stored in NWIS are accessible using existing tools such as NWIS-Web and the USGS Data Grapher system.
Data for Montane-breeding Bird Distribution and Abundance across National Parks of Southwestern Alaska, 2004-2008
Observation data and model covariate data from breeding bird inventory conducted during May-June 2004 and 2008 primarily in montane areas (>100 m above sea level) in Aniakchak National Monument and Preserve (Aniakchak NMP), Katmai National Park and Preserve (Katmai NPP), and Lake Clark National Park and Preserve (Lake Clark NPP) in southwestern Alaska. Observers conducted 1,021 point counts along
Landsat classification of surface water for multiple seasons to monitor inundation of playa wetlands
To improve understanding of the distribution of important, ephemeral wetland habitats across the Great Plains, we documented the occurrence and distribution of surface water in playa wetland complexes for four different years across the Great Plains Landscape Conservation Cooperative (GPLCC) region. Years of research on playas has yielded multiple mechanisms and projections for sub-regions of the
Elevation of salt marsh units in Edwin B. Forsythe National Wildlife Refuge, New Jersey
Elevation distribution in the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA is given in terms of mean elevation of conceptual marsh units defined by Defne and Ganju (2016). The elevation data is based on the 1-meter resampled 1/9 arc-second resolution USGS National Elevation Data. As part of the Hurricane San
Continuous Bathymetry and Elevation Models of the Massachusetts Coastal Zone and Continental Shelf
Integrated terrain models covering 16,357 square kilometers of the Massachusetts coastal zone and offshore waters were built to provide a continuous elevation and bathymetry terrain model for ocean planning purposes. The area is divided into the following four geographical areas to reduce file size and facilitate publishing: Massachusetts Bay from the Massachusetts-New Hampshire border south to Pr
Exotic invasive giant apple snails (Pomacea maculata) will depredate eggs of frog and toad species of the Southeastern United States
Frog eggs of three different species were presented to giant apple snails (Pomacea maculata) to determine if the snails will eat the eggs. There were four treatments: control-eggs in water only; control with lettuce-eggs in water and lettuce which was used as snail food; snail-eggs in water with snail; and snail with lettuce-eggs in water with snails and lettuce (as an alternative food for the sna
Historical produced water chemistry data compiled for the Fruitvale Oilfield, Kern County, California
This dataset contains geochemical and other information for 204 samples of produced water from the Fruitvale petroleum field. Produced water is water coexisting with oil and gas. The historical produced water chemistry data was compiled from preexisting datasets and scanned images into a numerical dataset to characterize produced water chemical characteristics. Each sample is identified by its API
Surface-Water for Washington
Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Washington. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
Effects of local shoreline and subestuary watershed condition on waterbird use: influences of geography, scale, and season in the Chesapeake Bay
In many coastal regions throughout the world, there is increasing pressure to harden shorelines to protect human infrastructures against sea-level rise, storm surge and erosion. This study examines waterbird community integrity in relation to shoreline hardening and land use characteristics at three geographic scales: (1) the subestuary scale characterized by seven shoreline types: bulkhead, ripr
Annual Streamflow Sensitivity to Air Temperature Worldwide, 1901-2013
The purpose of the dataset is to quantify the sensitivity of streamflow to air temperature at 2,673 gages around the world and to evaluate a theory for predicting that sensitivity. This is the second of two datasets containing derived data necessary to reproduce the results of the associated journal article: "On the Sensitivity of Annual Streamflow to Air Temperature," intended for publication in
