Data and Tools
Biology and Ecosystems Datasets
Mapping, Remote Sensing, and Geospatial Data
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.
Reproductive strategy, spawning induction, spawning temperatures and early life history of captive sicklefin chub Macrhybopsis meeki-Data
Macrhybopsis reproduction and propagule traits were studied in the laboratory using two temperature regimes and three hormone treatments and which methods produced the most spawns. Results from this study determined the reproductive biology and early life history of Macrhybopsis spp. and provided insight into their population dynamics in the Missouri River.
Datasets of High-throughput DNA Sequencing, Genetic Fingerprinting, and Quantitative PCR from Upper Klamath Lake, Oregon, 2013-14
Monitoring the community structure and metabolic activities of cyanobacterial blooms in Upper Klamath Lake, Oregon, is critical to lake management because these blooms degrade water quality and produce toxic microcystins that are harmful to humans, domestic animals, and wildlife.
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions of storm-induced coastal flooding, erosion, and cliff failures over large geographic scales. CoSMoS projections are currently available for the north-central coast (Half Moon Bay to Pt. Arena), San Francisco Bay, and southern California.
Supplemental data from: Hydraulic characterization of volcanic rocks in Pahute Mesa using an integrated analysis of 16 multiple-well aquifer tests, Nevada National Security Site, 2009–14
This USGS data release represents tabular data and water-level modeling files for the 16 Pahute Mesa multiple-well aquifer tests conducted from 2009–2014. The data release was produced in compliance with the new 'open data' requirements as a way to make the scientific products associated with USGS research efforts and publications available to the public.
We examined if eDNA approaches could detect seasonal changes in the occurrence of DNA in water samples and used these approaches to calculate the probability of detection of DNA within samples. To do this, we developed a novel genetic marker that was able to both detect and differentiate bighead and silver carp DNA.
These environmental raster covariate, geospatial vector data, and tabular data were compiled as input data for the Automated Reference Toolset (ART) algorithm. These data are a subset of all the environmental raster covariate data used in the ART algorithm.
Data on ambient-shade temperature, Normalized Difference Vegetation Index (NDVI) between February 1, 2010 and January 31, 2011 used for input onto a bioenergetics-based movement model for Galapagos turtles.
These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys."
Data were compiled or measured (depending on the trait) for 110 plant species which were documented in vegetation monitoring surveys in years 2012-2014 along the Colorado River through Grand Canyon National Park. New trait data were collected for specific leaf area, stem specific gravity, δ13C, δ15N, percent carbon and nitrogen, and carbon:nitrogen ratio.
These datasets include data that was used to evaluate the efficacy of carbon dioxide (CO2) injected under-ice as a tool for reducing the overwinter survival of invasive carps.
Physical, chemical and bioassay data from an evaluation of metal-contaminated sediments and pore water from the Upper Columbia River, Washington, 2013-2014
Chemistry and toxicity data from sediment toxicity tests conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Toxicity testing was conducted with the amphipod, Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea.
Water resources data are published annually for use by engineers, scientists, managers, educators, and the general public. These archival products supplement direct access to current and historical water data provided by the National Water Information System (NWIS). Beginning with Water Year 2006, annual water data reports are available as individual electronic files.
