Defining the oxic-suboxic interface is often critical for determining pathways for nitrate transport in groundwater and to streams at the local scale. Defining this interface on a regional scale is complicated by the spatial variability of reaction rates. The probability of oxic groundwater in the Chesapeake Bay watershed was predicted by relating dissolved O2 concentrations in...

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in collaboration with the National Park Service, provide lidar-derived first-surface and bare-earth topography for Cape Cod National Seashore, Massachusetts. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) during October 2002.

The study area included the coasts of all five U.S. states along the northern Gulf of Mexico (i.e., Florida, Alabama, Mississippi, Louisiana, and Texas). We contacted federal, state, and university-affiliated scientists working with SET-MH data within this area to obtain the geographic coordinates and the installation year for each SET-MH station. Please note that while our inventory is...

Macroclimatic drivers, such as temperature and rainfall regimes, greatly influence ecosystem structure and function in tidal saline wetlands. Understanding the ecological influence of macroclimatic drivers is important because it provides a foundation for anticipating the effects of climate change. Tidal saline wetlands include mangrove forests, salt marshes, and salt flats, which occupy...

Estimated precipitation data were compiled using the WestMap web site (http://www.cefa.dri.edu/Westmap/) from 1995-2013. We selected pixels on the map shown on their web site that were in the core of our study areas: one near Palm Springs, California and the other at Sugarloaf Mountain in the Tonto National Forest of Arizona. WestMap uses PRISM data to make point measurements of climate...

Acoustic telemetry is a popular tool for the study of fish spatial ecology. In acoustic telemetry, fish are captured, surgically implanted with an acoustic transmitter or "tag", and then released back into the environment. Networks of autonomous, stationary receivers then are used to track the movements of tagged individuals over long periods of time (greater than 1 year). Each acoustic...

This data release includes vertical offset information for the regionally extensive Main Terrace in the Lower Rhine Graben in the border region between Germany, Beligum, and Netherlands. These data are used in an investigation exploring the temporal and spatial pattern of Quaternary fault slip rates in this region and are the subject of an investigation by Gold and others (in review at...

These maps show the potential of widespread slope failures, in terms of landslide probabilities and displacement, triggered by a M7.0 scenario earthquake on the Hayward Fault in the 10-county area surrounding the San Francisco Bay region, California. The likelihood of landsliding was evaluated using an equation developed by Jibson and others (2000) that estimates landslide probability as...

Estimates of low-flow statistics at un-gaged locations were computed at multiple locations throughout New Jersey during the 2016 Water Year using methods in the USGS report, Streamflow Characteristics and Trends in New Jersey, Water Years 1897-2003 (Watson, et.al, 2005). The estimates are provided for use in water resources assessment and management by the New Jersey Department of...

This dataset provides point locations of wetlands in the Cottonwood Lake Study Area to aid in identification of study area wetlands.

Collection of orthorectified images from aerial photograph of wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota. This collection of image were acquired during July and early August from 1975 to 2015. Aerial photographs of wetlands in the Cottonwood Lake Study Area were collected in order to facilitate a better understanding of the influence of natural climate...

This dataset collects sea surface temperature data generated through alkenone analysis of late Pliocene sediments collected from cores and field localities by USGS PRISM project members. Alkenone analysis of sample material was performed by Timothy Herbert at Brown University.
