Strontium/Calcium (Sr/Ca) ratios act as a proxy for sea surface temperature (SST) in the skeletons of aragonite producing organisms, such as massive corals. The Sr/Ca-SST proxy shows promise when applied to single Orbicella faveolata colonies in the Atlantic/Caribbean regions, but it is currently unknown how well the Sr/Ca-SST proxy performs between colonies of this species. It is necessary to und

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 o

Nitrapyrin is a nitrification inhibitor that is co-applied with N-fertilizer in agroecosystems. Over the course of one year (March 2016 to June 2017), 192 water samples from seven streams across Iowa and Illinois were analyzed for nitrapyrin, its degradate 6-chloropicolinic acid (6-CPA), and three widely used herbicides acetochlor, atrazine, and metolachlor. Additional environmental samples were c

Groundwater is an important source of drinking and irrigation water throughout Idaho, and groundwater quality is monitored by various Federal, State, and local agencies. The historical, multi-agency records of groundwater quality include a valuable dataset that has yet to be compiled or analyzed on a statewide level. The purpose of this study is to combine groundwater-quality data from multiple so

These data consist of sulfur and carbon isotope compositions, concentrations of selected elements, and concentrations of pyrite sulfur and organic carbon in mudstone samples collected from five cores drilled in the Howards Pass district, Yukon-Northwest Territories, Canada. The cores were drilled between 2006 and 2014, site visits and core sampling took place between 2009 and 2016, and laboratory

As part of the Louisiana Coastal Protection and Restoration Authority's Barrier Island Comprehensive Monitoring Program, scientist from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore single-beam bathymetry survey along the Chenier Plain, Louisiana from Marsh Island to Sabine Pass. The goal of the BICM program is to provide long-term data on

This data set contains the concentration results for water- and sediment-quality and tissue samples, as well as associated quality-assurance data, collected at sampling locations located in the Rocky Mountain National Park, Colorado. Samples were collected between 2012 and 2013. Samples were analyzed for nutrients, hormones, pharmaceutical, wastewater indicator compounds and pesticides, at the U.S

We investigated the dynamics of canine distemper virus (CDV) in grizzly bears (Ursus arctos) and wolves (Canis lupus) of the Greater Yellowstone Ecosystem using serological data collected from 1984 to 2014. 565 sera samples were obtained from 425 unique grizzly bears (134 females and 291 males) from 1984 to 2014 and 319 sera samples were obtained from 285 unique wolves (130 females and 155 males)

This data collection is associated with the project: "Status and Trends of Deciduous Communities in the Bighorn Mountains". It contains the project study area, model evaluation data, model input data, and model output data in the form of probability of occurrence rasters for deciduous and coniferous species, as well as a synthesis map. The aim of the study is to assess the current trends of decid

The Orange Tuff is an informally named tephra-fall deposit that crops out extensively in the volcanic highlands to the south and southwest of Bogor, West Java, Indonesia. The data included in this data release documents the deposit thickness and maximum sizes of lithics present at sites throughout its distribution. Additional tables document dispersal areas calculated from within hand-drawn isopac

The data frame provides geo-referenced data on presence of six species of en route migrant shorebirds in wetlands within the prairie pothole region in the U.S. during the spring migration periods of 2002 and 2012. Surveys were conducted at wetlands within townships selected in a stratified random procedure, with strata based on landscape composition of agricultural cropland and total area of wetla

This data release consists of two ESRI geodatabases that store inundation areas for various future scenarios of sea-level rise (SLR), groundwater rise, and storm waves for Laysan Island and Midway Atoll in the Northwestern Hawaiian Islands. Five types of inundation scenarios are considered: (1) passive SLR, (2) passive SLR including groundwater rise, (3) wave-driven inundation during storm events,
