These data describe the catch and biological data from 363 bottom-set gill-net lifts distributed throughout Lake Michigan (including main basin and Green Bay) between April and November in 1930–1932. Data collected from the R/V Fulmar were recorded in notebooks and are now archived at the U.S. Geological Survey’s Great Lakes Science Center. Each lift included 1–7 gangs of linen gill nets. Each gang comprised 3–5 panels each having a length of 155 m, a height of 1.5 m, and a (stretch-)mesh size of either 60, 64, 67, 70, or 76 mm. The digitization of the Fulmar data notebooks was started in the late 1990s and finished in this study.

Here we present the data collected during a mark-recapture study on freshwater mussels in Bruce Creek, Walton County, Florida. These data were used to evaluate the non-lethal impacts of a gill sampling protocol to assess gravidity of freshwater mussels. Data were collected every four weeks, or as weather permitted, to be able to monitor the reproductive status of each mussel every month of the year. The dataset includes unique tag numbers to identify specific female mussels captured and recaptured during this study. Genus and species were identified, and the gravidity status was evaluated for each individual mussel.

Remote sensing technologies, such as high-resolution sonar, can be used to collect more detailed information about the benthic and water column characteristics of macro habitats in the Illinois River. Multibeam echosounders (MBES) collect multibeam and sidescan simultaneously, providing high-resolution images of the riverbed. Sidescan images, in raster format, show the recorded intensity of acoustic signal returns from the riverbed. The acoustic data were collected from the main and side channels (where accessible) of the Dresden reach June 4 – 28, 2018.

Hydroacoustic (sonar) data were collected for the Mississippi, St. Croix, and Minnesota Rivers for the development of high-resolution bathymetry and sidescan imagery. Small areas containing priority mussel habitat had additional collection efforts to map water velocities and bottom composition. Combining these data in a GIS can provide key components to characterizing physical benthic habitat for native mussels in a riverine environment. These information needs were highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution. The collaborative effort was funded by the Legislative-Citizen Commission on Minnesota Resources (LCCMR) Environment...

This dataset is a digital elevation model (DEM) of the bathymetry for six sites where known rock structures exist in the St. Croix River. The DEMs have a 10-cm resolution (Boom site is 0.5-m) to provide ultra-high-resolution elevations for investigating the use of hydroacoustic technologies for quantifying habitat for imperiled mussels Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) typically associated with rock structures (e.g., wing dams, revetment) in rivers. Bathymetry is essential for providing the depths and shapes of underwater terrain and it represents the three-dimensional features (or relief) of underwater terrain. Multibeam sonar data were collected using a Norbit integrated...

Benthic invertebrate communities are monitored because the composition of those communities can affect and be affected by the water quality of an aquatic system. Benthic communities use and sometimes regulate the cycling of essential elements (for example, carbon). Benthic invertebrate taxa may also indicate acute and chronic stressors in an environment because they accumulate contaminants and can respond – sometimes dramatically - to oligotrophic and eutrophic conditions. Benthic communities affect water quality by grazing pelagic food resources and increasing the rate of nutrient regeneration through feeding and bioturbating sediments. South San Francisco Bay is a system dependent on phytoplankton as the base...

Montgomery County, Maryland Department of Environmental Protection has collected datasets to assess the health of streams since the early 1990s. Datasets include geomorphic stream cross-sectional surveys, fish and benthic macroinvertebrate counts and taxa abundance, and water chemistry data collected at the time of benthic and fish sampling (dissolved oxygen, pH, specific conductance, air temperature, and water temperature). Data span years 1992 to 2020 at five watersheds within the Clarksburg study area. Watersheds include a forested reference site (Soper), an urban site with centralized stormwater management (Crystal Rock), and three treatment watersheds (TR104, TR109, and Cabin Branch) within the Clarksburg Special...

Sediment particles can strongly bind metals, effectively repartitioning them from solution to a solid phase. As a result, sediments may accumulate and retain metals released to an aquatic environment. Sediment cores provide a historical record of metal inputs that can reveal anthropogenic influences (Förstner and Wittmann, 1979). Specifically, studies of sediment cores in San Francisco Bay chronicled metal inputs and suggested that legacy contamination can remain a chronic source of metals to the system owing to sediment mixing and redistribution (Hornberger and others, 1999; Van Geen and Luoma, 1999). Metals in sediments also indicate exposure levels to benthic animals through contact with, and ingestion of, bottom...

Stable isotope data of fauna, particulate organic matter, and rocks collected during the 2018 research cruise aboard the NOAA Ship Bell M. Shimada that examined benthic communities off the western U.S. coast.
The data include measurements of chlorophyll a and algal stoichiometry from benthic algae collected from Sky Pond, Rocky Mountain National Park, Colorado, in 2015-2017; results of nutrient diffusion experiments in Sky Pond including chlorophyll a and other pigments to identify chlorophytes, bacillariophytes, and myxomycetes, and results of a laboratory incubation using benthic chlorophytes to identify ecosystem responses (nitrogen uptake, net primary productivity, ecosystem respiration, net ecosystem productivity, and dissolved organic carbon production) under nutrient and temperature treatments.

Data provided from the Virginia Department of Environmental Quality (DEQ) including simulated values of 72 hydrologic metrics, or indicators of hydrologic alteration (IHA), 37 fish metrics, and 64 benthic invertebrate metrics were reviewed to assess significant flow-ecology relations that may be developed. Hydrologic alteration was represented by simulation of streamflow record for a pre-water-withdrawal condition (baseline) without dams or developed land, compared to the simulated recent-flow condition (2008) including withdrawals, dams and altered landscape to calculate a percent-alteration of flow. Biological samples used represent a median condition of the biological community from 1972 to 2010. This study reviewed...

This dataset is a digital surface of depth-averaged flow velocities for six sites where known rock structures exist in the St. Croix River. Acoustic Doppler Current Profilers (ADCP) are used to measure how fast water is moving across an entire water column. The ADCP measures water currents with sound, and the resulting flow information will be used for investigating the use of hydroacoustic technologies for quantifying habitat for imperiled mussels Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) typically associated with rock structures (e.g., wing dams, revetment) in rivers. River current velocities were collected using a SonTek RiverSurveyor© M9 for all six sites. All hydroacoustic...

Data to support the site characterization of locations sampled along the continental shelf and slope of the western U.S. coast off Washington, Oregon and California during the EXPRESS RL1905 expedition in 2019. Data consisted of tissue samples from fauna, sediments and particulate organic matter. These samples were analyzed for stable carbon and nitrogen isotopes to examine food web ecology. Additional observational data were collected through video analyses with efforts focused on documenting counts of fauna other than corals, sponges and fishes, as well as general habitat characteristics.

Seafloor character was derived from interpretations of air photo derived kelp distribution data available for the Santa Cruz Island (Kushner and others 2013). The number of substrate classes was reduced because rugosity could not be derived for all areas.

Recent advances in hydroacoustic technology are proving to be valuable tools for mapping habitat features for sedentary biota such as freshwater mussels, and has the potential to identify and quantify habitat features. The Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) are imperiled mussels that are typically associated with rock structures (e.g., wing dams, revetment) in rivers. Hydroacoustic data were collected in early May of 2021 for 6 pre-determined sites containing rock structures within the St. Croix River, to determine whether hydroacoustics can identify and quantify habitat features for imperiled mussels such as the Spectaclecase and Salamander.

Data from 10-day sediment toxicity tests of bed sediments from the Niagara River area of concern and tributaries, Niagara and Erie County, New York. Specifically, the data was used to compare the survival and growth of two macroinvertebrate species in sediments from study sites and laboratory controls. Results are from 10-day sediment exposures of two test species, Chironomus dilutus and Hyalella azteca. Bed-sediments were collected from depositional areas using either a petite Ponar (0.03 square meter) dredge or a stainless steel sediment scoop. At each site, approximately five grabs or scoops were composited into a bucket, mixed, and a 4-liter (L) subsample was stored in a polyethylene container. Sediment toxicity...
