Data

Regressions were developed to predict Escherichia coli (E. coli) concentrations at four U.S. Geological Survey (USGS) gages on streams in Chester and Delaware Counties in southeastern Pennsylvania. The regression analysis was based on 2019-24 discrete E. coli concentrations measured in samples collected approximately monthly by USGS from April to October and concurrent available...

These spatial and tabular data were compiled to have a decades-long record of the water usage in the riparian corridor for 27 selected sites where tamarisk (Tamarix spp) or saltcedar defoliation was reported by ground observations and/or exhibited in Google Imagery at locations across the Lower Colorado River Basin. Data for these sites was measured remotely for plant health as...

These data document over a century of plant community change on the Colorado Plateau (CP) using repeat photography (1910-2016). Photos were taken across a 3100 square kilometer area on the CP largely in areas administered by the NPS and Bureau of Land Management (BLM), including (but not limited to) areas now within Arches National Park and Canyonlands National Park; Glen Canyon National

This data release contains a timeseries (2004-2025) of photographs from five permanent locations (Stops 1-5, roughly 11x15 centimeters) established to observe biological soil crusts (BSC, a collection of species of lichens, cyanobacteria, and bryophytes). The five locations were randomly located within a larger study area established to monitor vegetation and biological soil crusts as...

The Louisiana State Legislature established the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) to conserve, restore, create and enhance Louisiana's coastal wetlands. Restoration plans developed under CWPPRA require evaluating the effectiveness of each project in achieving long-term solutions to coastal wetlands loss. This data set includes mosaicked aerial photographs...

The table contains observations of American black bears reported by community members to the website: https://massbears.wordpress.amherst.edu from 2019-2023. To preserve the privacy of the contributors, locations were rarefied by 1000 m.

Observations of locations where the August 18th, 1992 eruption of Mount Spurr was heard and not heard around Alaska.

Oaks were mapped in a portion of Yolo County, California, USA. For 26 focal trees, acorn counts were conducted from 2013-2023. Trees were located in rural and urban areas. Rural trees were located visually and location was recorded. Urban tree locations were drawn from randomly distributed point locations at 1.2 valley oaks per hectare. The data also include distance between oak trees to...

This data release presents chemical and biological results from an investigation of the fish uptake and effects from exposure to per- and polyfluoroalkyl substances (PFAS) from groundwater contaminated by fire training activities on Cape Cod, Massachusetts. Twenty-one day exposure experiments were conducted from July to August 2019 and from August to September 2021 using groundwater from...

This data release contains respiration and clearance rate data collected from laboratory experiments. Fatmucket mussels (Lampsilis siliquoidea) were placed in sealed containers to determine their oxygen consumption and excretion rates at two different environmentally relevant temperatures. Mussels were then placed into containers with food to determine how quickly they consume 2-60...

We examined enhanced turbulence levels as an alternative grass carp (Ctenopharyngodon idella) control strategy through turbulence-induced mortality at embryonic stages. We exposed pre-water-hardened and water-hardened grass carp eggs to increased levels of turbulence in a grid-stirred turbulence tank to find threshold values of turbulence parameters and shear stresses that have lethal...

A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values at 19 sites across the mountainous regions of Puerto Rico. The 19 sites were co-located at the United States Geological...
