Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2023 Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2023
Estimates of various low-flow statistics were computed at 56 ungaged stream locations throughout New Jersey during the 2023 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications...
Global aquatic Isoëtes Database (acronym GaID) as of 2024 Global aquatic Isoëtes Database (acronym GaID) as of 2024
Isoëtes are iconic but understudied wetland plants, despite having suffered severe losses globally mainly because of alterations in their habitats. We therefore provide the first global, comprehensive data set of aquatic Isoëtes and their habitats. We compiled a global database that includes all known environmental data collected from 1935 to 2023 regarding aquatic Isoëtes. This resulted...
Data and Code Release: Acute Toxicity of Lampricides to Non-target Species of Concern in the Lake Champlain Watershed Data and Code Release: Acute Toxicity of Lampricides to Non-target Species of Concern in the Lake Champlain Watershed
Data to evaluate the Acute Toxicity of Lampricides to Non-target Species of Concern in the Lake Champlain Watershed. The toxicity of the lampricides TFM and TFM/1% Niclosamide to numerous non-target fishes of concern in the Great Lakes has been presented in previous studies. However, not many toxicity studies have been reported for Finger Lakes and Lake Champlain species of concern...
Per- and polyfluoroalkyl substances along the St Louis River and in the Duluth, MN area 2019-2021 Per- and polyfluoroalkyl substances along the St Louis River and in the Duluth, MN area 2019-2021
Tree swallow nest boxes were deployed at sites proximal to two putative aqueous film forming foam (AFFF) sources in the Duluth, MN area, as well as along the St. Louis River and a reference lake for comparative purposes. The two AFFF sites were the current Duluth Air National Guard Base (ANG) and the Lake Superior College Emergency Response Training Center. Concentrations of between 13...
Location and land cover uncertainty associated with stop-level data from the North American Breeding Bird Survey (BBS) Location and land cover uncertainty associated with stop-level data from the North American Breeding Bird Survey (BBS)
The North American Breeding Bird Survey (BBS) (https://www.pwrc.usgs.gov/bbs/) has counted birds annually for over fifty-five years. Survey 'routes' each consist of 50 'stops' (point counts) placed along a route path. Inter-stop distances and stop locations can vary from route to route and from year to year, and precise locations of each stop are not typically recorded. This data set...
Ellsworth Huntington’s (1914) Giant Sequoia Ages and Tree-Ring Measurements from 458 Stumps in Sequoia National Forest and Mountain Home Grove Ellsworth Huntington’s (1914) Giant Sequoia Ages and Tree-Ring Measurements from 458 Stumps in Sequoia National Forest and Mountain Home Grove
These data include giant sequioa (Sequoiadendron giganteum) age and tree-ring data from measurements on 458 stumps. The original data were recorded on paper data sheets by Ellsworth Huntington and his assistants in 1911 and 1912; their methods are elaborated in Huntington (1914), and further details can be found in Stephenson and Demetry (1995). We entered the data from photocopies of...
