This dataset contains CSV files for raw and processed stream biological data used in an analysis of temporal synchrony of proglacial rivers. Data include water quality metrics, fish survey data, and biomass calculations.

Ciénegas are wetlands in arid and semi-arid regions of North America. We quantified changes in ciénega condition and floodplain dynamics using the detailed boundaries of 31 ciénegas and their respective controls.This data release is a series of four data collections consisting of 68 tabular data files (.csv) that include the following: (i) “i_Cienega_Timeseries_CSVs.zip” data collection...

These Holocene aged samples are from three sediment cores obtained near the Provincetown Hook spit in Cape Cod, Massachusetts. The goal of the geochronology work is to determine when shoreface sediments, which represent the oceanward extent of the spit, were present at the surface for the Provincetown Hook. Results from this work support efforts to publish more recent sedimentological...

This dataset describes environmental DNA (eDNA) sample collections, DNA extractions, and DNA copy numbers (abundance of environmental DNA) for cisco Coregonus artedi, a native prey fish of restoration interest in the Laurentian Great Lakes, in tributaries to Lake Huron’s North Channel in Canada. Samples were collected during cisco spawning runs (mid-November) from 2022-2024.

This data set includes metadata for fish and microbes from water samples collected in southern Lake Michigan in August 2021. All field eDNA samples were collected using a Tethys-class Long Range Autonomous Underwater Vehicle (LRAUV) carrying an eDNA sampler, the 3G Environmental Sample Processor (ESP). Water samples were collected at various depths within following target layers: the...

We used visual encounter surveys (VES) and environmental DNA (eDNA) surveys for amphibians in the western united states. Data are results of both VES and eDNA surveys for all amphibian species that occur in the locations surveyed.

Craig County, Virginia hosts large (>500 m wide) blockslides and rock slumps along the southeastern slopes of several mountains. These features differ from Virginian boulder fields in several aspects, most significantly in soil development, foliage, and clast size. In contrast with freshly exposed, likely periglacial, boulder fields that commonly contain centimeter to meter-sized...

Glacial and proglacial landscapes provide critical sources of water and solutes to downstream riverine and marine ecosystems. This dataset contains samples from the dominant landscape types in the Nellie Juan River basin, collected from surface streams, groundwater, rain, and snow. Water samples were also collected from streams near the Exit, Gulkana, and Kennicott Glaciers. Snow samples...

Two digital video cameras (CACO-01 c1 and c2) were installed at Head of the Meadow Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras were located near the top of the 18 meter high bluff and faced north-east (c1) and east (c2) along the beach. They ran from December...

Pollutants present in stormwater runoff can severely degrade water quality in aquatic habitats. The tire-derived chemical 6PPD-quinone is one such pollutant present in stormwater that is known to significantly impact the survival of salmonids. 6PPD-quinone is derived from 6PPD, the primary antiozonant used to protect tire rubber from ozone attack and degradation. Alternative antiozonants...

Aspen stands (Populus tremuloides Michx.) are declining in western U.S. forests due to drought, changing climate, and altered disturbance regimes. Management of aspen has focused on promoting vegetative suckering, which requires viable rootstock. With increasing wildfire frequency and severity in the West, there are opportunities for aspen reforestation post-fire. We tested how deadwood...
