Data Releases
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.

Occurrence of Chlamydia sp in apparently healthy birds associated with a mortality event caused by chlamydiosis: Data
hese data sets are is a compilation of bird and environmental samples obtained from 6 sites in Maricopa County, Arizona on the dates shown. Sites were only visited and sampled if they had Rosy-cheeked lovebirds coming to bird feeders at the location and with the permission of the property owner. Two swab samples were obtained from each captured bird and 3 swab samples were collected from the envir
Data release for ecosystem service flows from a migratory species: spatial subsidies of the northern pintail
Migratory species provide important benefits to society, but their cross-border conservation poses serious challenges. By quantifying the economic value of ecosystem services (ES) provided across a species range and ecological data on a species habitat dependence, we estimate spatial subsidieshow different regions support ES provided by a species across its range. We illustrate this method for mig
Diurnal patterns of methane flux from a depressional, seasonal wetland
Data on diurnal variation in wetland methane flux were collected to 1) improve understanding of short-term, mechanistic drivers of methane flux, and 2) inform sampling protocols to achieve research objectives. An automated gas flux sampling system was used to measure methane flux every 2.5-4 hours for over 230 diel cycles over the course of three growing seasons (2013-2015). Data were collected fr
Argon geochronology data from the Austroalpine-Pennine boundary, Central Alps, Switzerland
Ar/Ar data are reported from eight samples of white mica separated from rock samples collected along the Austroalpine-Pennine boundary in the Central Alps of Switzerland. These samples were collected as part of a Caltech PhD study to examine the tectonic history of this boundary and these argon geochronology data represent one small part of the study. Data are reported from these eight samples tog
Multimetric Index macroinvertebrate values from the Fountain Creek Basin, Colorado 2005 to 2016.
These data have been collected as part of a cooperative project in between the U.S. Geological Survey Colorado Water Science Center, Colorado Springs Utility, and Colorado Springs Engineering. This project began in 2005 and has collected macroinvertebrate samples from Fountain Creek and its tributaries to monitor the biological condition of this watershed. Provided in this data release are Multime
HAVO Montane Ohia Diameter and Cavity Data 2017
We quantified the availability of breeding habitat of the endangered Hawaii Akepa (Loxops coccineus). The species is thought to nest excusively in natural cavities within mature ohia (Metrosideros polymorpha) trees but birds commonly occur in short stature trees that presumably do not have any natural cavities because of their polyploidal (many-branched) structure. To test this hypothesis we searc
Sampling data collected in Cape Cod Bay, Buzzards Bay, and Vineyard Sound; south of Martha's Vineyard; and south and east of Nantucket, Massachusetts, in 2011, U.S. Geological Survey Field Activity 2011-015-FA
Sampling survey 2011-015-FA was conducted aboard the OSV Bold in September 2011 by the U.S. Geological Survey and Massachusetts Office of Coastal Zone Management with partners from the U.S. Environmental Protection Agency and Massachusetts Division of Marine Fisheries. Three hundred twenty-two stations were occupied with the large SEABOSS, where operational, or the ship's Van Veen grab sampler in
Channel Island Grazer Removal Data 2004-2016
This data includes data and metadata of (1) the percent cover of all species found along transects on the south facing slopes of Santa Cruz Island, CA (2) the height of all shrub individuals on transects on the south facing slopes of Santa Cruz Island, CA and (3) location data of on the south facing slopes of Santa Cruz Island, CA. Data were used in the analysis for the Manuspcript "Long-term impa
Beaver-related Stream Restoration Projects in Western Rangelands
We systematically surveyed federal and state wildlife biologists, hydrological specialists, non-profit organizations, and working groups focused on beaver or wetland restoration in the western U.S. We focused primarily on contacting land managers from states containing some portion of the Great Basin, although many of the projects described in surveys fell outside of this watershed. Some land mana
Salt marsh carbon dynamics under altered hydrologic regimes and elevated CO2 conditions, Louisiana, USA (2014-2015)
Plant-mediated processes are often important in determining carbon cycling and storage in ecosystems. With climate-induced changes in the environment, plant-associated processes may also shift. Salt marshes in particular are useful systems to investigate plant-mediated carbon cycling, as these systems experience both sea-level rise and increased carbon dioxide concentrations due to climate change,
Tidal marsh biomass field plot and remote sensing datasets for six regions in the conterminous United States
Remote sensing based maps of tidal marshes, both of their extents and carbon stocks, have the potential to play a key role in conducting greenhouse gas inventories and implementing climate mitigation policies. Our objective was to generate a single remote sensing model of tidal marsh aboveground biomass and carbon that represents nationally diverse tidal marshes within the conterminous United Stat
Non-native fishes of the central Indian River Lagoon
We provide a comprehensive review of the status of non-native fishes in the central Indian River Lagoon (from Cape Canaveral to Grant-Valkaria, east of I-95) through literature review and field surveys. Historical records exist for 17 taxa (15 species, one hybrid, one species complex). We found historical records for one additional species and collected one species in our field survey that had nev
