Data

In-situ nearshore seawater measurements of dissolved radon and water level were used to determine the advection rate of groundwater onto the fringing reef off Ofu, American Samoa.

This data release includes nest box field observations (N = 98 nest boxes) and avian egg tissue laboratory analyses (N = 60 eggs) collected from Lake Koocanusa (also known as Koocanusa Reservoir) and the Kootenai River Basin, Montana, 2022-2023. Nest box field observation data (occupancy rate, clutch size, and hatching success) and avian eggs were collected by the U.S. Fish and Wildlife...

These data contain acceleration, pitch, yaw, roll, and ancillary data collected by acceleration data loggers (ADL) attached to four sea turtle species: green (Chelonia mydas) sea turtles, hawksbill (Eretmochelys imbricata) sea turtles, Kemp's ridley (Lepidochelys kempii) sea turtles, and loggerhead (Caretta caretta) sea turtles. A total of 54 nesting events and 76 non-nesting emergence...

This dataset includes apparent nest density (observed nests per hectare of area searched) of mallard (Anas platyrhynchos) and gadwall (Mareca strepera) in Suisun Marsh, California.

1. Abstract Landslides are common across Southeast Alaska (SEAK) and have caused damages and fatalities in populated areas. Better understanding of landslide triggering conditions and impacts can inform risk reduction strategies and alerting efforts. Landslide inventory data with weekly to hourly time resolution are needed to quantify these conditions. Local news sources are a source of...

This metadata record documents four 30-meter raster data layers; 1) elevation, 2) hydro-enforced elevation, 3) flow direction, and 4) flow accumulation for the conterminous United States. The datasets are derived from the NHDPlus Version 2.1 regional raster datasets and presented here as Cloud Optimized GeoTIFFs (COGs).

This layer represents fundamentally suitable and unsuitable habitat for freshwater mussels in the Meramec Basin as modeled by these authors on May 17, 2017 based on spatial data ranging from 1990 to 2014. Identification of habitat characteristics associated with the presence of freshwater mussels is challenging but crucial for the conservation of this declining fauna. Most mussel species...

This dataset includes (i) camera-based detection data for nine-banded armadillos (Dasypus novemcinctus) and coyotes (Canis latrans) and (ii) covariates characterizing the environmental conditions at each of 100 sites sampled in the Wichita Mountains Wildlife Refuge during summer 2023.

The U.S. Geological Survey’s National Water Quality Network (NWQN) is the primary source of data to monitor trends in contaminants in groundwater in the United States. However, other data sources are available to evaluate trends. The Water Quality Portal (WQP) and the National Groundwater Monitoring Network (NGWMN) portal provide data that can be used for groundwater quality trends in...

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed were calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2023. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted...

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed were calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2024. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...

Nocardia spp. are opportunistic pathogens of humans, domestic animals, and wildlife that can cause high levels of morbidity and mortality. Reported cases of nocardiosis in Aves are rare. We diagnosed nocardial airsacculitis in a free-ranging mallard duck (Anas platyrhynchos) from Arizona, USA. Histopathology showed multiple granulomas expanding the air sac with intralesional filamentous...
