Hurricane Sandy Beach Response and Recovery at Fire Island, New York-Shoreline, Beach Profile Data, and Breach Shoreline Data, October 2012 to October 2017

Owen T Brenner, Rachel E Henderson, Cheryl J Hapke & Billy J Reynolds
Fire Island, New York is the site of a long term coastal morphologic change and processes project conducted by the U.S. Geological Survey (USGS). One of the objectives of the project was to understand the morphologic evolution of the barrier system on a variety of time scales (months-years-decades-centuries). In response to Hurricane Sandy (October 2012), this effort continued with the intention of resolving storm impacts, post-storm beach response, and recovery. The day before Hurricane Sandy...

Ovary mass and stable hydrogen isotope data for resident and migratory female dark-eyed juncos

Craig A Stricker
This dataset includes ovary mass and stable hydrogen isotope compositions of feathers and claws from resident and migratory female dark-eyed juncos (Junco hyemalis) collected during early spring at Mountain Lake Biological Station, Pembroke, Virginia. A total of 18 migrant and 15 resident female dark-eyed juncos, a songbird that exhibits seasonal sympatry, were caught during March-April. Stable hydrogen isotopes were used to infer relative breeding and wintering latitude of migrants. Ovary mass served as a proxy...

Northern Arizona Ponderosa Pine Forest Treatment Terrestrial Lidar Data

Jonathon J. Donager, Temuulen Ts. Sankey, Joel B Sankey, Andrew J. S´┐ŻNchez Meador, Abraham E. Springer & John D. Bailey
These are terrestrial laser scanner datasets collected in forested areas west of Flagstaff, Arizona in 2015 and 2016. For each of the two scanners, six treatment areas were scanned, with four of them overlapping one another (Figure 1). These data are composed of individual scans referenced to one another using reflective targets, and geolocated using differentially corrected GPS and RTK locations of scan locations (Figure 3). There were overall large differences in point density among...

Aerial Photography Single Frame

Earth Resources Observation And Science Center
The Aerial Photography Single Frame Records collection is a large and diverse group of imagery acquired by Federal organizations from 1937 to the present. Over 6.5 million frames of photographic images are available for download as medium and high resolution digital products. The high resolution data provide access to photogrammetric quality scans of aerial photographs with sufficient resolution to reveal landscape detail and to facilitate the interpretability of landscape features. Coverage is predominantly over the...

Petrologic and Mineral Physics Database for use with the USGS National Crustal Model - Data Release

Theron Sowers & Oliver S Boyd
We present a petrologic and mineral physics database as part of the USGS National Crustal Model (NCM) for the western United States. Each of 209 geologic units, 134 of which are currently part of the geologic framework within the NCM, is assigned a mineralogical composition according to generalized classifications with some refinement for specific geologic formations. The mineral physics database builds off of previous work to include several minerals specific to continental rock types. We...

Susan G. Buto
This dataset represents "phreatophyte areas" mapped as part of a groundwater reconnaissance effort in four valleys in central Nevada and published in 1964. The data were digitized for comparison with mapping of groundwater discharge areas done in 2011 as part of a groundwater study in these valleys published in 2016.

Water-surface elevations derived from submersible pressure transducers deployed along the Salcha River, AK, July -October 2018

Paul J Kinzel
The U.S. Geological Survey deployed seven submersible pressure transducers on the bottom of the Salcha River in July 2018. An additional transducer was left out of the water to correct for barometric pressure fluctuations. At the time of deployment, the bank position near each transducer and the water-surface elevation were measured with Global Navigation Satellite System (GNSS) equipment. The transducers recorded a depth measurement every 15-min until the recovery of five of the seven in...

Woody species crown and vegetation community data, Palmyra Atoll, 2016

Matthew A. Struckhoff
Photo-interpretation of high-resolution aerial imagery was used to delineate individual stems of select woody species and to map vegetation communities at Palmyra Atoll, USA. Imagery collected using Unoccupied Aerial Systems in October, 2016, as well as derived elevation and mosaicked orthoimagery, were used to delineate individual crowns of coconut, Pisonia and other selected woody species that comprise the bulk of the canopy on the island. National Vegetation Classification System vegetation associations and other vegetation communities...
