County-Level Estimates of Nitrogen and Phosphorus from Animal Manure for the Conterminous United States, 2007 and 2012 and 30-Meter-Resolution Grid of Counties (2010), Conterminous United States

There are two datasets in the compressed file along with individual metadata files which completely describe the datasets.  The first  data set consists of county estimates of nitrogen and phosphorus in kilograms from animal manure for the conterminous United States for 2007 and 2012. These data are available as both text files and spreadsheets. These estimates were based on county-level population data of livestock, poultry, and other animals (cattle, poultry, hogs and pigs, horses and ponies, sheep and lambs) from the 2007 and 2012 Census of Agriculture, using methods described in U.S. Geological Survey Scientific Investigations Report 2006-5012. The second dataset is a 30 by 30 meter (m) resolution grid of counties in the conterminous United States as defined in the year 2010 that was used to assign the animal population per county. This county grid allows the first dataset described to be compared to prior publications of nitrogen and phosphorus content of manure.

Walking transect path

We designed a 12.2 km walking transect so that an observer would pass within 50m of all habitat in the estuary and also minimize fording large channels. This transect was drawn using the path tool in Google Earth on a satellite image of the survey area. The path was printed on top of paper maps and used by observers as a map in the field. Most often, the entire transect was walked by two observers, one starting in the far West, the other in the middle of the estuary. Observers were permitted to deviate from the map to get clear views of certain features like incised channels or to identify a particular bird. The transect spacing worked for most birds, but was too sparse to accurately count Belding’s Savannah Sparrows. In general, the transect was walked from west to east, though there was no fixed direction and observers could choose a direction based on convenience and the angle of the sun.

Bird point locations by date and species at Carpinteria Salt Marsh

In 30 surveys, we mapped 21,486 birds comprising 88 species “interact with” the intertidal habitat. Each full “survey” represents a unique month-year-tide combination (but not necessarily a unique day). Specifically, for each of 15 months between January 2012 and March 2013 we conducted separate, but temporally adjacent high-tide and low-tide bird surveys (30 in total) throughout the intertidal habitats. Back to back surveys within the same month are not meant to be independent measures of bird abundance and should be averaged to get an idea of bird abundance in a particular month. Birds were counted if they were in the intertidal habitat. We also counted some species, like raptors, if they were perched in adjacent upland habitats, but potentially interact with the estuary. We include information on the distribution of raccoon latrines that were persistent in this habitat during the study period.

Primary production across a coastal wetland landscape in Louisiana, U.S.A. environmental data (2012-2014)

Above- and belowground production in coastal wetlands are important contributors to carbon accumulation and ecosystem sustainability. As sea level rises, we can expect shifts to more salt-tolerant communities, which may alter these ecosystem functions and services. Although the direct influence of salinity on species-level primary production has been documented, we lack an understanding of the landscape-level response of coastal wetlands to increasing salinity. What are the indirect effects of sea-level rise, i.e. how does primary production vary across a landscape gradient of increasing salinity that incorporates changes in wetland type? We measured above- and belowground production in four wetland types that span an entire coastal gradient from fresh to saline marsh.

GIS Features of the Geospatial Fabric for National Hydrologic Modeling

The Geopspatial Fabric provides a consistent, documented, and topologically connected set of spatial features that create an abstracted stream/basin network of features useful for hydrologic modeling.The GIS vector features contained in this Geospatial Fabric (GF) data set cover the lower 48 U.S. states, Hawaii, and Puerto Rico. 
Four GIS feature classes are provided for each Region: 1) the Region outline ("one"), 2) Points of Interest ("POIs"), 3) a routing network ("nsegment"), and 4) Hydrologic Response Units ("nhru"). A graphic showing the boundaries for all Regions is provided at http://dx.doi.org/doi:10.5066/F7542KMD. These Regions are identical to those used to organize the NHDPlus v.1 dataset (US EPA and US Geological Survey, 2005). Although the GF Feature data set has been derived from NHDPlus v.1, it is an entirely new data set that has been designed to generically support regional and national scale applications of hydrologic models. Definition of each type of feature class and its derivation is provided within the &lt;dataqual&gt;&lt;lineage&gt; section of this metadata document. The first &lt;procstep&gt; entry in that section provides an overview of the delineation process, with each subsequent &lt;procstep&gt; corresponding to one of the four types of feature. These &lt;procstep&gt; entries describe the derivation of feature types in the order in which they are created. Minimal attribution (feature size, location, and routing connectivity) is provided for the feature classes within the GF Feature data set. More extensive feature attribution is published separately as individual tables of attributes(for example, http://dx.doi.org/doi:10.5066/F7RX9937) or via entire configurations of tables engineered to satisfy particular watershed models (for example, http://dx.doi.org/doi:10.5066/F7WM1BF7).

Zinc concentrations and isotopic signatures of an aquatic insect (mayfly, Baetis tricaudatus)

Insect metamorphosis often results in substantial chemical changes that can fractionate isotopes and alter contaminant concentrations. We exposed larval mayflies (Baetis tricaudatus) to an aqueous zinc gradient (3-340 µg Zn/l) and measured the change in zinc tissue concentrations at different stages of metamorphosis. We also measured changes in stable isotopes (δ15N and δ13C) in unexposed B. tricaudatus. Zinc concentrations in larvae were positively related to aqueous zinc, increasing 9-fold across the exposure gradient. Zinc concentrations in adults were also positively related to aqueous concentrations, but were 7-fold lower than larvae. However, this relationship varied according to adult substage (subimago vs imago) and sex. Tissue concentrations in female imagoes were not related to exposure concentrations, but the converse was true for all other stage by sex combinations. Metamorphosis also altered isotopic ratios, increasing δ15N, but not δ13C. Thus, the main effects of metamorphosis on insect chemistry were large declines in zinc concentrations coupled with enriched δ15N signatures. For zinc, this change is largely consistent across the aqueous exposure gradient. However, the differences among sexes and stages suggest that caution is warranted when using isotopes or metal concentrations measured in one insect stage (e.g., larvae) to assess risk to wildlife that feed on subsequent life stages (e.g., adults).

Geographic Information System (GIS) shapefile of the bathymetric contours of Lago Caonillas, Utuado, Puerto Rico, September- November 2012

This dataset contains the shapefile of the bathymetric contours generated from field data collected in the Lago Caonillas between September and November 2012 by U.S. Geological Survey. The 2012 bathymetric survey was conducted using a bathymetric/land survey system, consisting of a global positioning system (GPS) coupled to a digital depth sounder. A total of 155 survey navigation lines were established at 50 meter (m) intervals, beginning at the dam and continuing upstream along the river branches of the reservoir. Geographic position (accuracy of less than 2 m) and water depths (accuracy of 2 centimeters [cm] ±1 percent of the measured depth) were acquired simultaneously using the GPS interfaced to the depth sounder. Data points were color-coded according to their specific depths, and same-color points were connected with a line to draw depth contours. Lago Caonillas is owned and operated by the Puerto Rico Electric Power Authority (PREPA) since 1996. Because of the importance of Lago Caonillas to the North Coast Superaqueduct, the U.S. Geological Survey (USGS), in cooperation with PRASA, conducted a sedimentation survey of Lago Caonillas between September and November 2012 to update estimates of the reservoir’s storage capacity.

Ecological community datasets used to evaluate the presence of trends in ecological communities in selected rivers and streams across the United States, 1992-2012 (output)

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality and ecological conditions change over time.  To support that goal, long-term consistent and comparable ecological monitoring has been conducted on streams and rivers throughout the Nation.  Fish, invertebrate, and algae data collected as part of the NAWQA program were retrieved from the USGS Aquatic Bioassessment database for use in trend analysis.  Ultimately, these data will provide insight into how natural features and human activities have contributed to changes in ecological condition over time in Nation’s streams and rivers.  This USGS data release contains all of the input and output files necessary to reproduce the results of the ecological trend analysis described in the associated U.S. Geological Survey Scientific Investigations Report. Data preparation for input to the model is also fully described in the above mentioned report.

Organic matter decomposition along coastal wetland landscape gradient from tidal freshwater forested wetland to oligohaline marsh in Southeastern U.S.A. (2010-2011)

Coastal wetlands significantly contribute to global carbon storage potential. Sea-level rise and other climate change-induced disturbances threaten coastal wetland sustainability and carbon storage capacity. It is critical that we understand the mechanisms controlling wetland carbon loss so that we can predict and manage these resources in anticipation of climate change.

Determining the habitat suitability of coastal waterbirds in New Jersey: impacts related to Hurricane Sandy

Understanding the long-term consequences of hurricane effects on wildlife and their habitats is critical to efficiently and effectively protect and restore important coastal wetland and marsh habitat. Hurricane Sandy caused widespread and substantial physical, environmental, ecological damage, likely impacting the food supplies, habitats, and reproductive success of many animal species along the coast.  Further, physical alterations to habitats throughout the impacted area significantly increased the region’s vulnerability to future storm events, posing new risks to communities and ecosystems.
