2013-14 Massachusetts Lidar-Derived Dune Toe Point Data

This data release of dune metrics for the Massachusetts coast is part of a 2018 update to the Massachusetts Shoreline Change Project. Because of continued coastal population growth and the increased threat of coastal erosion, the Massachusetts Office of Coastal Zone Management (CZM) launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. Maps of historic shoreline locations from the mid-1800s to 1978 were produced from multiple data sources, and in 2001, a 1994 shoreline was added to enable the calculation of long- and short-term shoreline change rates. In 2013, the U.S. Geological Survey (USGS), in cooperation with CZM, delineated an additional oceanfront shoreline using 2007 topographic lidar data and 2008–9 color aerial orthoimagery.
Further cooperation between CZM and the USGS resulted in this 2018 update, intended to increase the understanding of coastal erosion and to support coastal management decision making. This update includes beach shorelines, marsh shorelines, and dune metrics, all of which were derived from topographic lidar data. This data release, which is part of the 2018 update, defines the position and elevation of the most seaward dune crest and toe along the Massachusetts coast as derived from 2013–14 lidar data. In the absence of a dune, the peak of the berm or the seaward edge of a bluff, headland, or hard structure (for example, a seawall, road, or parking lot) was chosen as a proxy for the dune crest. Where possible, the dune toe was placed at the base of the proxy feature.

Geophysical Data Collected in the Cedar River Floodplain, Cedar Rapids, Iowa, 2015-2017

A suite of geophysical methods was used along the Cedar River in Cedar Rapids, Iowa to support the hydrogeologic characterization of the alluvial aquifer associated with the river and to assess the area for suitability for larger-scale airborne geophysics.  The aquifer is comprised of sand and gravel, interbedded with finer sediments, and underlain by carbonate-dominated bedrock. The aquifer is the principal source of municipal drinking water for the City of Cedar Rapids.  The raw data files provided here include waterborne continuous resistivity profiling (CRP) and continuous seismic profiling (CSP) data, which were collected concurrently in April 2015, electrical resistivity tomography (ERT) profiles from April 2015, horizontal to vertical spectral ratio (HVSR) seismic from April 2015 and several borehole geophysical logs including nuclear magnetic resonance (NMR), gamma, and electromagnetic induction (EMI) from nine wells, collected in June, 2017. 
The CRP, ERT, and borehole logs measure the electrical properties of the subsurface, which can be related to stratigraphic layers. The HVSR, CSP, CRP and some of the borehole logs characterize the depth to bedrock. Collectively the suite of methods can help characterize the subsurface and map the extent of the sand and gravel aquifer.  In addition, these geophysical measurements can be used to plan and to ground truth air-borne electromagnetic surveys.

Monthly timescale quick-flow runoff maps for the conterminous U.S., 1895-2017

This dataset includes 1km resolution monthly timescale estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 1895-2017. These estimates were developed with a regression for surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1301 gaged watersheds as a function of surficial geology type (USGS), precipitation (PRISM), slope (NHD), and soil hydraulic conductivity (STATSGO). The quantities for quick-flow runoff do not include inter-pixel transfers, so do not capture within-watershed variations due to such transfers such as downstream runoff accumulation, but rather represent the portion of the precipitation entering each cell that ultimately contributes to the quick-flow runoff component. Methods are fully described in an article in the Journal of Hydrology; this dataset will be updated with the complete article citation when available.

Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934–2017

The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for recreational activities, businesses, and downstream users, and provide habitat for several threatened or endangered species. 
The areas pertinent to the recharge process are the catchment area and the recharge zone. The catchment area consists of the parts of stream basins upstream from the recharge zone. Streams in the catchment area generally gain water (hence the term "catchment area") as they flow toward the recharge zone. As the streams flow across the recharge zone, which is essentially the outcrop of the Edwards aquifer, they lose substantial amounts of water through infiltration into the highly permeable, faulted and fractured rocks of the outcrop. Direct infiltration of rainfall also occurs in the interstream areas of the recharge zone. 
Annual recharge estimates are based on data collected from a network of U.S. Geological Survey (USGS) streamflow-gaging stations at sites upstream and downstream from the recharge zone and on assumptions related to applying runoff characteristics from gaged areas to ungaged areas (Puente, 1978). Runoff is affected by the distribution of rainfall, which historically has been estimated from a network of rain gages, some operated by the USGS, some by the Edwards Aquifer Authority (EAA), and some by the National Weather Service. Since 2004, the distribution of rainfall has been estimated from calibrated NEXRAD (NEXt-generation weather RADar) data provided by the EAA. The annual estimation of recharge to the Edwards aquifer is part of a continuing program of the USGS in cooperation with the Edwards Aquifer Authority. 
This data release is formatted as a tab-delimited file (.txt) that contains the estimated annual recharge to the Edwards Aquifer for the years 1934 through 2017. The estimated annual recharge is divided into eight major river basins of the catchment area and for some of those basins, will also include estimates of recharge from adjacent ungaged areas.

Potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2016, raster format, in feet

A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. Most of the wells were measured annually or one time, after installation, but some wells were measured more than one time in a year and a small number of wells were measured continually. Streamgages were typically operated continuously. The potentiometric surface map for 2016 was created as part of the U.S. Geological Survey (USGS) Water Availability and Use Science Program to support investigations that characterize the MRVA aquifer. The potentiometric contours ranged from 10 feet to 340 feet above NAVD 88. The regional direction of groundwater flow was generally towards the south-southwest, except in areas of groundwater-altitude depressions, where groundwater flows into the depressions, and near rivers, where groundwater flow generally parallels the flow in the rivers. There are large depressions in the potentiometric surface in the lower half of the Cache region and in most of the Grand Prairie and Delta regions.

High-resolution digital elevation model for Mount Adams and vicinity, Washington, based on lidar surveys of August-September, 2016

Mount Adams, also known by the Native American names "Klickitat" or "Pahto", is a 3,742 meter-tall (12,278 feet) stratovolcano located 53 km (33 miles) north of the Columbia river straddling the borders of Skamania County, Yakima County and the Yakama Nation Reservation. Mount Adams lies in the middle of the Mount Adams volcanic field—a 1,250 square kilometer area (about 480 square miles) comprising at least 120, mostly basaltic volcanoes that form spatter and scoria cones, shield volcanoes, and some extensive lava flows. The volcanic field has been active for at least the past one million years. Mount Adams was active from about 520,000 to about 1,000 years ago and has erupted mostly andesite. Eruptions have occurred from ten vents since the last period of glaciation about 15,000 years ago. The volcano has produced a larger volume (about 300 cubic kilometers or 70 cubic miles) of eruptive material during the past million years than any other Cascade stratovolcano, surpassed only by Mount Shasta (about 350 cubic kilometers or 85 cubic miles). Approximately 6,000 and 300 years ago, debris avalanches from the southwest face of Mount Adams generated clay-rich lahars that swept more than 30 square kilometers (11 square miles) south of the volcano along the White Salmon River. The summit of Mount Adams contains a large section of unstable, hydrothermally-altered rock that can spawn future debris avalanches and lahars. This DEM (digital elevation model) represents the ground surface beneath forest cover of Mount Adams and adjacent vicinity. It is the product of high-precision airborne lidar (Light Detection and Ranging) surveys conducted during August and September of 2016 by Quantum Spatial under contract with the USGS; total area is 2278.6 square kilometers (879.8 square miles). This release consists of DEM and corresponding hillshade rasters. The survey area is divided into four sections: adams_edifice.tif, adams_indian_heaven.tif, adams_west.tif, and adams_east.tif. Hillshade images are spatially coincident to the DEM from which they are derived. Filenames appended with the suffix “_hs” indicate hillshade images (e.g. adams_edifice_hs.tif).

Visual Surveys Rapid Response Saipan 2016

Nocturnal visual encounter survey data conducted by 29 searchers over 17 transects obtained during a Brown Treesnake rapid response deployment to island of Saipan in 2016. Surveys took place in the vicinity of the Saipan airport and Dandan village (ca. 15.127°N, 145.735°E) from 06 January to 13 March 2016, 6–7 nights/week but with a break in surveying from 26 January through 21 February. During Brown Treesnake searches over 386.8 kilometers, we collected data on selected vertebrate taxa (lizards and small mammals, both potential snake prey) recorded from survey transects with similar vegetation structure (secondary forest dominated by the introduced leguminous tree Leucaena leucocephala; emergent trees were partially denuded from typhoon Soudelor which had passed over Saipan on 02 August 2015).

Water-level contours along the Lower Platte and Lower Elkhorn Rivers, Nebraska, 2016-2017

This data set contains two sets of water-level contours that represent interpreted water-levels for an area between the Platte and Elkhorn Rivers upstream of their confluence. The contours are informed by surface-water and groundwater-level data collected during a synoptic water-level survey completed during a low-groundwater demand period in fall of 2016 and a synoptic water-level survey completed during a high-groundwater demand period in summer of 2017.  Additional data and interpretations of this dataset (published in SIR XXXX) and the data included in this Data Release are intended to inform water managers of the effect of groundwater demand and flow conditions on groundwater movement and interaction with surface-water for the area near and immediately upstream from the confluence of the lower Platte and Elkhorn Rivers.

Nutrient and algal response values from a mesocosm experiment used to estimate algal growth rates

These data have been collected as part of a cooperative project between the U.S. Geological Survey (USGS) and the U.S Environmental Protection Agency. This project began in 2016 and consisted of a mesocosm experiment quantifying short term responses by a transplanted natural diatom dominant algae community exposed to gradients of nitrogen, phosphorous, and a mixture of both nitrogen and phosphorus. The data consist of water quality parameters such as temperature and pH as well as aqueous nutrient concentrations and algae responses, including chlorophyll a concentrations, algae dry mass, algae ash-free dry mass, and intra-cellular phosphorus and nitrogen in algae. Algae growth rates were estimated from these data and are meant to be used with water-quality models; the results of this investigation can be found in the manuscript associated with this data release (Schmidt and others 2019).
