Rangeland systems are some of our nation’s largest providers of agro-ecological services, sustaining plant productivity that is highly variable across seasons and years. Although the ability to predict the upcoming growing season’s rangeland productivity would have enormous economic and management value – such as for making decisions about cattle stocking rates, fire, restoration, and wildlife – the ability to provide these forecasts has remained poor. New remote sensing and modeling technologies allow for dramatic improvements to near-term forecasts of rangeland productivity. With this project, our multi-disciplinary team has shown that, compared with traditional remote sensing greenness indices, NIRv-based (NIR...

In 2011, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, began a study of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys in the Town of Newfield, Tompkins County, New York. The objective of this study was to characterize the hydrogeology and water quality of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys and produce a summary report of the findings. This dataset contains locations of moraines and ice margins identified with lidar imagery in West Branch Cayuga Inlet and Fish Kill Valleys, Newfield, Tompkins County, New York.
The Retsof salt mine in the Genesee River Valley, Livingston County, New York, flooded after mine-roof collapses in 1994 created two rubble chimneys in overlying bedrock that intersected a confined aquifer in the basal glacial-drift deposits and continued collapse to the land surface. Groundwater in the lower confined aquifer flowed downward through the bedrock rubble chimneys causing widespread drawdown in the lower confined aquifer until the mine was completely flooded in 1996 (Yager and others, 2001). By 2005, water levels in the lower confined aquifer had nearly recovered to pre-collapse conditions but the hydraulic connection through the rubble chimneys between the brine-filled mine cavity, saline-water bedrock...

This folder contains the raw and processed TEM data and inverted soundings showing resistivity (in ohm-m) with depth for all survey sites that were part of transect 10. In October and November 2016-2017, transient electromagnetic (TEM) data, also called time domain electromagnetic (TDEM) surveys, were acquired at 120 locations in the Genesee Valley, Livingston County, in New York, in order to characterize the subsurface resistivity structure in support of a U.S. Geological Survey groundwater investigation. The TEM data were collected as part of a project to evaluate geophysical methods to characterize the valley-fill sediments, underlying bedrock, and salinity of the subsurface. TEM data were collected using an...

From May 2017 to November 2019, the U.S. Geological Survey conducted bathymetric surveys of New York City's East of Hudson Reservoirs. Bathymetry data were collected at Kensico Reservoir from June to August, 2018. Depth data were collected primarily with a multibeam echosounder. Quality assurance points were measured with a single-beam echosounder. Water surface elevations were established using real-time kinematic (RTK) and static global navigation satellite system (GNSS) surveys and submersible pressure transducers. Measured sound velocity profiles were used to correct echosounder depth measurements for thermal stratification. Digital elevation models were created by combining the measured bathymetry data with...
This page contains horizontal-to-vertical spectral ratio (HVSR) data for 28 measurements, LVHVSR1 through LVHVSR97. In October and November of 2016 and 2017, the U.S. Geological Survey collected horizontal-to-vertical spectral ratio (HVSR) data at 104 sites in the Genesee Valley, Livingston County, New York as part of a saline-groundwater investigation in cooperation with the New York State Department of Environmental Resources. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008). The passive-seismic method uses a single, broad-band three-component (two horizontal and one vertical)...

The purpose of this project was to document processes for USGS scientists to organize and share data using ScienceBase, and to provide an example interactive mapping application to display those data. Data and maps from Chase and others (2016a, b) were used for the example interactive maps. Principal Investigator : Katherine J Chase, Andy Bock, Thomas R Sando Accomplishments The accomplishments for this project are described below. The project team developed an interactive mapping application in R that connects to data on ScienceBase, using Shiny, Leaflet (Cheng and Xie, 2016), and sbtools (Winslow and others, 2016) (fig. 10). USGS scientists can refer to the R code in the mapping application to build their...
The USGS National Land Cover Trends Project has the largest repository of field photos at the USGS (over 33,000 photos). Prior to CDI funding, Land Cover Trends had limited funding to make the national collection of photos available online for researchers, land managers, and citizens. The goal of this CDI project was to add geotags and keywords to the digital copies of each field photo and make the collection searchable and downloadable via the Internet. By funding the effort to integrate Land Cover Trends field photography and online mapping technology, CDI has helped provide access to geographic data needed to conduct science and support policy decisions. Sharing georeferenced photography distributed across the...

Large online data catalogs use controlled vocabularies to categorize datasets in ways that allow end users to sort and select data matching their needs. The eventual goal of this project is to build functional services so that the USGS Thesaurus and other USGS-controlled vocabularies will be available to the English-speaking scientific community, especially within the USGS where they can be used to improve metadata quality and data discovery. The project team used the Tetherless World Constellation (TWC) Semantic Web Methodology, which is designed to examine use cases and determine both functional and nonfunctional system requirements without prejudicial commitments to meeting those requirements by utilizing particular...

Legacy data (n) - Information stored in an old or obsolete format or computer system that is, therefore, difficult to access or process. (Business Dictionary, 2016) For over 135 years, the U.S. Geological Survey has collected diverse information about the natural world and how it interacts with society. Much of this legacy information is one-of-a-kind and in danger of being lost forever through decay of materials, obsolete technology, or staff changes. Several laws and orders require federal agencies to preserve and provide the public access to federally collected scientific information. The information is to be archived in a manner that allows others to examine the materials for new information or interpretations....

The goal of this project is to improve the USGS National Earthquake Information Center’s (NEIC) earthquake detection capabilities through direct integration of crowd-sourced earthquake detections with traditional, instrument-based seismic processing. During the past 6 years, the NEIC has run a crowd-sourced system, called Tweet Earthquake Dispatch (TED), which rapidly detects earthquakes worldwide using data solely mined from Twitter messages, known as “tweets.” The extensive spatial coverage and near instantaneous distribution of the tweets enable rapid detection of earthquakes often before seismic data are available in sparsely instrumented areas around the world. Although impressive for its speed, the tweet-based...

The purpose of the Data Management Training (DMT) Clearinghouse project was twofold. First, the project aimed to increase discoverability and accessibility of the wealth of learning resources that have been developed to inform and train scientists about data management in the Earth sciences. Secondly, the project team wanted to facilitate the use of these learning resources by providing descriptive information (metadata) that can help research scientists, students, or teachers assess whether the resource would be appropriate and useful for their needs. The project team established the following objectives for the project: Create an online, searchable, and browsable clearinghouse of learning resources on data...

This dataset includes well logs used in the creation of the Ellicottville hydrogeologic framework. Well logs were used from multiple sources (DEC, DOT, NWIS, ESOGIS, and archived material) and were a crucial component in generating hydrogeologic layer elevations and thicknesses. Well logs are available in their original form on GeoLog Locator (https://webapps.usgs.gov/GeoLogLocator/#!/) and provided here in the digitized form (shapefiles and feature classes), which were used in the generation of the hydrogeologic framework.

This dataset includes spreadsheets with statistical data (mean and median absolute error) used in deciding which interpolation method best fit the corresponding dataset. All statistical data were paired with a visual inspection of the interpolation prior to determining the final raster product. All spreadsheets were generated using an automated python script (Jahn, 2020).
Digital hydrogeologic datasets were developed for the Cortland study area in upstate New York in cooperation with the New York State Department of Environmental Conservation. These datasets define the hydrogeologic framework of the valley-fill aquifer and surrounding till-covered uplands within the study area. Datasets include: bedrock elevation raster, lacustrine silt and clay top and bottom elevation rasters, lidar mean elevation raster, lacustrine extent polygon, valley-fill extent polygon, and surficial geology polygons. Elevation layers were interpolated at 125-foot discretization to match the model grid cell size.
