In order to allow for a comparison across years we visually digitized landcover of Poplar Island from a single image per year at a 1:1000 spatial extent with a minimum mapping unit of 300 square meters (no minimum dimensions aside from area). Images used to assign landcover were provided by the U.S. Army Corps of Engineers and were captured between July and October of their respective years. All images were 1 foot resolution.

Here we provide data used to report on changes in tidal marsh elevation in relation to our network of 20 fixed benchmarks located across a geographically broad network of coastal elevation monitoring stations with standard monitoring protocols. This dataset includes Surface Elevation Table (SET) measurements taken from 10 sites along the US Atlantic coast, ranging from Virginia to Maine. Each site includes 2 SETs where repeat measurements of wetland surface elevation were made from 2005-2019.

This data release links benthic macroinvertebrate sites to both the NHDPlus Version 2 and NHDPlus High Resolution Region 02 networks, hereafter referred to as V2 and HR, using the hydrolink methodology. Linked benthic macroinvertebrate sites are those included in the Chesapeake Bay Basin-wide Index of Biotic Integrity (Chessie BIBI) developed by the Interstate Commission on the Potomac River Basin (ICPRB) and available from the Chesapeake Bay Program (https://datahub.chesapeakebay.net/LivingResources). The data set contains a unique sample identifier created by ICPRB, survey program, coordinates of sample, linked V2 COMID and HR Permanent Identifier, and information regarding uncertainty in the attribution. We strongly...

The rusty-patched bumble bee (Bombus affinis) is a listed species under the Endangered Species Act of the United States. While understood to be a highly generalist forager, little is known on the role that limited floral resources or shifting floral community composition could have played in B. affinis decline. Determining which floral species provide suitable B. affinis forage could assist conservation efforts where B. affinis persists, identify floral species for restoration efforts, or highlight regions to search for cryptic populations.
Water levels in meters from four wells in Moneystump marsh at Blackwater National Wildlife Refuge, MD. Two wells are located in the upland forest; one well is located in the marsh-forest transition zone (ecotone); and one well is located in the marsh. Water depth of the adjacent creek is reported in meters. Data covers the time span from November 11 2016 - November 11 2017. Pressure transducer data from the wells corrected to water level using barometric pressure loggers located in 3 locations throughout the experiment. Water levels are in units of meters referenced to vertical datum NAVD88. Raw pressure data is in units of kilopascals (kPa). Pressure transducer locations and elevation data from GNSS and digital...

The USGS Water Mission Area (WMA) - Ecosystems Mission Area (EMA) EcoDrought project is comprised of interdisciplinary teams in five pilot regions across the country. The over-arching project goal is to measure streamflow in headwater streams and to relate flow variation to stream fish population dynamics. In the northeast, the New England Water Science Center (NewEngWSC) partnered with the fish ecology group at the S.O. Conte Anadromous Fish Research Lab (Conte), a part of the EMA’s Eastern Ecological Science Center. The Conte fish ecology team has been collecting ecological and stream water temperature data in the West Brook watershed located in Whately, Massachusetts, since 1997, where they developed novel methods...

This Data Release contains stream temperature observations for 28 sites in the Antietam Creek Watershed (Maryland) during summer 2021. Data were collected using Onset ProV2 temperature gages within perforated PVC cases attached to stream substrates with rebar. Temperature gages were deployed and retrieved by volunteers with the Antietam-Conococheague Watershed Alliance. Temperature records are provided for 20-minute increments between June 1 and August 31, 2021 (92 days, 6625 observations per site, and a total of 185,500 observations in the dataset). Site location coordinates are provided.

These data describe the results of virus isolation from oropharyngeal/cloacal swabs and testing of sera by a commercial blocking enzyme-linked immunosorbent assay (bELISA) and hemagglutinin (HA) specific testing by microneutralization (MN) and hemagglutination inhibition (HI) for Lesser Scaup in both the Atlantic and Pacific Flyways and Greater Scaup in the Pacific Flyway. These data support a USGS published manuscript.

Light intensity levels in lux from upper sensors in Moneystump marsh at Blackwater National Wildlife Refuge MD. There are 25 light sensors all located in the control treatment area. Five sensors are located in the lowest elevation (marsh), five located in the upper marsh, five located in the marsh-forest transition zone (ecotone), five located in the lower forest, and five located in the highest elevation (upper forest). Data covers the time span from October 1 2015 - September 30 2019.

Data are fish species occurrences in surveys made by backpack electrofishing and seining in shoal habitats in the Etowah River downstream from Allatoona Dam (n=10 surveys in 2010 and n=5 surveys in 2016; 20 taxa total) and in the Coosawattee River downstream from Carters Dam and re-regulation dam (n=11 surveys in 2010; 32 taxa total), Georgia, USA. Data for the Etowah River include counts of individuals for each species captured; data for the Coosawattee River are observed or not observed for each species in the data set.

This Data Release provides brook trout abundance records for pool habitats within 2 streams in Shenandoah National Park (Staunton River and Paine Run). The data were collected with 3-pass backpack electrofishing conducted during baseflow conditions between 2012-2021. This dataset enables spatial analysis of brook trout population responses to drought conditions.

Here we provide data used to report on changes in tidal marsh elevation in relation to our network of 387 fixed benchmarks in tidal marshes on four continents measured for an average of 10 years. During this period RSLR at these marshes reached on average 6.6 mm yr-1, compared to 0.34 mm yr-1 over the past millennia. While the rate of sediment accretion corresponded to RSLR, the loss of elevation to shallow subsidence increased in proportion to the accretion rate. This caused a deficit between elevation gain and RSLR which increased consistently with the rate of RSLR regardless of position within the tidal frame, suggesting that long-term in situ tidal marsh survival is unlikely. While higher tidal range (>3m) conferred...

Data shows CH4 fluxes from the upper portion of cypress knees across various climate and flooding gradients of the North American Baldcypress Swamp Network in the Mississippi River Alluvial Valley. Climate data in the form of temperature, relative humidity, barometric pressure, and precipitation 3-days leading up to sampling date are also included. There various forms to calculate fluxes using cone and frustrum shapes that were compared to LiDAR scans fromi the field, therefore surface area and volume for each geometric shape is also included in the dataset.
