Harmonizing wetland soil organic carbon datasets to improve spatial representation of 2011 soil carbon stocks in the conterminous United States Harmonizing wetland soil organic carbon datasets to improve spatial representation of 2011 soil carbon stocks in the conterminous United States

These datasets represent a revised national scale estimate of wetland soil carbon stock assessments by improving representation of soil organic carbon densities. This assessment is based on a three-step approach to harmonize survey and point-based data for predicting soil organic carbon density from percent organic carbon alone (or percent organic matter, with conversion), when reliable...

HASP HASP

The Hydrologic Analysis Package (HASP) can retrieve groundwater level and groundwater quality data, aggregate these data, plot them, and generate basic statistics. One of the benefits of HASP is its ability to aggregate two time-series of data into one record and generate statistics and graphics on hat record. By merging two data sets together, users can view and manipulate a much longer...

Hatchery-reared Roundtail Chub Data, Arizona USA Hatchery-reared Roundtail Chub Data, Arizona USA

These data were compiled as part of a larger study to evaluate post-stocking survival of hatchery-reared Roundtail Chub. We conducted a two year study (Dec. 2015 – Mar. 2017) in the upper Verde River at the Burnt Ranch stocking location near Paulden, Arizona. Young of year Roundtail Chub were acquired from the Arizona Research and Conservation Center in Cornville, Arizona. Passive...

Hawaii Island airborne detection of fungal pathogens of Ohia, 2016-2017 Hawaii Island airborne detection of fungal pathogens of Ohia, 2016-2017

This data release includes metadata and tabular datasets that document (1) Austropuccina, Ceratocystis and Myrtaceae qPCR (quantitative polymerase chain reaction) DNA detections in Passive Environmental Samplers (PES), (2) wind speed, wind gust speed, and wind direction measurements collected at two sites in the Kahuku Unit of Hawai'i Volcanoes National Park (HAVO) where paired PES were...

Hawaii Island forest bird phenology and morphometrics from 1994 to 2019 Hawaii Island forest bird phenology and morphometrics from 1994 to 2019

We examined data from multiple studies (1994-2020) conducted across the avian annual cycle, from multiple locations, to evaluate molt patterns and establish criteria for assignment of age and sex based on the WRP (Wolfe-Ryder-Pyle) method, or molt-cycle age classification system designed specifically for tropical species. In addition, we describe the phenologies of molt and breeding and...

Hawaii Volcanoes National Park, Puhimau Geothermal Area vegetation and abiotic data, 2011-2021 Hawaii Volcanoes National Park, Puhimau Geothermal Area vegetation and abiotic data, 2011-2021

This data release includes metadata and tabular data that documents survival of endangered Portulaca sclerocarpa, percent cover of vegetation surrounding Portulaca sclerocarpa, as well as soil depth and soil temperature. All data were taken between 2011-2021 in the Puhimau Geothermal Area in Hawaiʻi Volcanoes National Park.

Hawaiian Islands bioclimatic variables for baseline and future climate scenarios Hawaiian Islands bioclimatic variables for baseline and future climate scenarios

We integrated recent climate model projections developed for the State of Hawai’i with current climatological datasets to generate updated regionally defined bioclimatic variables. We derived updated bioclimatic variables from new projections of baseline and future monthly minimum, mean, and maximum temperature (Tmin, Tmean, Tmax) and mean precipitation (Pmean) data at 250 m resolution...

Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios

Global downscaled projections are now some of the most widely used climate datasets in the world, however, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we apply steps to improve the utility of two such global datasets (CHELSA and WorldClim2) to provide credible climate scenarios for climate change impact studies in...

Hawaiʻi Island Survival of Ceratocystis in Frass 2019-2020 Hawaiʻi Island Survival of Ceratocystis in Frass 2019-2020

This data release includes data and metadata used in the estimation of Ceratocystis lukuohia survival in ambrosia beetle frass under various temperature and humidity conditions on Hawaiʻi Island. Data were used in the analysis of the manuscript, "Ceratocystis lukuohia-infested ambrosia beetle frass as inoculum for Ceratocystis wilt of Metrosideros polymorpha." Frass was exposed at two...

Health assessment of invasive northern snakehead in the Potomac River drainage, 2006 - 2017. Health assessment of invasive northern snakehead in the Potomac River drainage, 2006 - 2017.

Data described herein was collected by USGS personnel and the project funded by USGS. Northern snakehead specimens were collected from the Potomac River and its tributaries by regional natural resource management agencies in the course of their field investigations working with this priority invasive aquatic species. Specimens were provided to USGS for the purpose of conducting health...

Heat flow maps and supporting data for the Great Basin, USA Heat flow maps and supporting data for the Great Basin, USA

Geothermal well data from Southern Methodist University (SMU, 2021) and the U.S. Geological Survey (Sass et al., 2005) were used to create maps of estimated background conductive heat flow across the greater Great Basin region of the western US. The heat flow maps in this data release were created using a process that sought to remove hydrothermal convective influence from predictions of

Heat tracing of potential groundwater seepage zones along the upper Coonamessett River bog area (Cape Cod, Massachusetts, 2021) Heat tracing of potential groundwater seepage zones along the upper Coonamessett River bog area (Cape Cod, Massachusetts, 2021)

Locations of focused groundwater seepage to surface water are often hydrologically and ecologically important. Spatially focused or 'preferential' seepage can be identified as anomalous cold zones compared to warmer adjacent bank and surface water features (in summer). The temperature of deeper groundwater on Cape Cod is expected to approximate 11 degrees Celsius year-round, yielding a...
