Lake Michigan Fish Acoustic Data from 2011 to 2016

Area backscattering (ABC), mean acoustic size (sigma), and fish density in the intervals and layers of acoustic survey transects of Lake Michigan in the years 2011-2016. The data were collected to provide information on the temporal and spatial dynamics of the pelagic fish community of Lake Michigan. This information is used to provide an understanding of community and population drivers and in a

Fluctuating asymmetry in waterbirds in relation to mercury exposure

The dataset includes the bird species, sex, mercury concentration in breast feathers and whole blood, and the composite measure of fluctuating asymmetry. Statistical models were developed for each species to analyze the relationship between mercury exposure in either breast feathers or whole blood and the composite measure of fluctuating asymmetry, while accounting for the sex of each bird.

Distribution of Sediments at Crocker Reef, Florida, 2013-2014

Understanding the processes that govern whether a coral reef is accreting (growing) or dissolving are fundamental to questions of reef health and resiliency. The Reefscape Characterization task of the Coral Reef Ecosystem Studies (CREST) project is focused on geochemical, geologic, and metabolic processes that affect carbonate precipitation and dissolution on coral reefs. For the 1-km x 1-km study

Beach Slopes of New Jersey

The National Assessment of Coastal Change Hazards project derives features of beach morphology from lidar elevation data for the purpose of understanding and predicting storm impacts to our nation's coastlines. This dataset defines mean beach slopes along the United States Northeast Atlantic Ocean for New Jersey for data collected at various times between 2007 and 2014. For further information reg

EAARL Coastal Topography-Fire Island, New York, 2002

These Digital Elevation Model (DEM) and XYZ datasets provide lidar-derived bare-earth topography for Fire Island, New York. Elevation measurements were acquired on October 25 and November 8, 2002 by the first-generation Experimental Advanced Airborne Research Lidar (EAARL) in cooperation with the National Park Service (NPS) and the National Aeronautics and Space Administration (NASA).

Landsat 8 six spectral band data and MODIS NDVI data for assessing the optimal regression tree models

In this study, we developed a method that identifies an optimal sample data usage strategy and rule numbers that minimize over- and underfitting effects in regression tree mapping models. A LANDFIRE tile (r04c03, located mainly in northeastern Nevada), which is a composite of multiple Landsat 8 scenes for a target date, was selected for the study. To minimize any cloud and bad detection effects in

Pesticide concentration and streamflow datasets used to evaluate pesticide trends in the Nations rivers and streams, 1992-2012

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 conditions change over time. To support that goal, long-term consistent and comparable monitoring has been c

Groundwater Watch (New York)

Groundwater Watch displays maps, graphs, and tables describing real-time, recent, and historical groundwater data from wells and springs across the United States. Groundwater Watch groups related wells and data from active well networks and provides basic statistics about the water-level data collected by the USGS and from data supplied to us from partners through cooperative agreements.

WaterWatch (New York)

USGS Water Watch displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis. WaterWatch provides streamgage-based maps that show the location of more than 3,000 long-term (30 years or more) USGS streamgages.
