This is a tabular data set that includes intensity and saturation measurements of benthic invertebrates, sample residue, and preservative from samples stained with three fluorescent dyes for the development of a fluorescent staining method to enhance picking efficiency. This data set also contains data evaluating a selected fluorescent method's effects on picking efficiency and comparison to standard non-fluorescent methods for sorting benthic invertebrates.

The data describe the number, density, date of collection, and exact collection location of fish eggs (from multiple species) collected in the St. Clair and Detroit Rivers from 2005-2016.

A breach in the White Dam has been proposed to facilitate fish passage. As a Technical Assistance project, the U.S. Geological Survey provided toxicity assessments of sediment samples collected by USEPA personnel. These data describe water-quality conditions in exposure chambers during 42-d sediment exposures using the freshwater amphipod, Hyalella azteca.

The exposure of white-footed mice (Peromyscus leucopus) to lead and cadmium and the potential associated toxic effects were examined at three sites contaminated with lead in the Southeast Missouri Lead Mining District and at a reference site. Mice from the contaminated sites showed evidence of oxidative stress and red-blood cell δ-aminolevulinic acid dehydratase (ALAD) activity was depressed by an average of 68% at the most contaminated site. However, histological examinations of the liver and kidney, cytologic examination of blood smears and biomarkers of lipid peroxidation and DNA damage failed to show evidence of toxic effects from lead. The biomagnification ratio of cadmium (hepatic concentration/ soil concentration)...

Real-time, high frequency (1-second sample interval) GPS location, water quality, and water isotope (δ2H, δ18O) data was collected in the Cache Slough Complex (CSC), located in the northern San Francisco Bay Delta (SFBD). Data was collected on 10/01/2014 for an approximate 4-hour period (10:30 – 14:30 h PST) while underway on the R/V Mary Landsteiner, a 26-foot USGS vessel. Sample water was pumped continuously through a pickup tube, passed through a 178 micron pre-filter, a de-bubbler, and diverted through a 0.2 micron filter and an unfiltered flow path to water quality instrumentation. The real-time data were recorded using a Campbell Scientific CR-6 data logger. Water isotopes (δ2H, δ18O) were logged to a separate...

The Great Lakes Research Vessel Operations data release is taken from the Research Vessel Catch (RVCAT) database curated at the Great Lakes Science Center (GLSC). RVCAT has been used as the primary data collection tool aboard the GLSC’s research vessel operations. Content: The data set has been collected on various vessel operations on all the Great Lakes and select connecting waterways between the years 1958-2018. Data collection begins in early spring and ends in late fall. Each vessel operation was completed for a specific purpose, or target mission, which are enumerated in this data set. In addition to vessel operations data, RVCAT collects trawl and gillnet catch data, sample information of fish species caught,...

A study was conducted to assess the efficacy of drainage setbacks for limiting effects to wetlands in the Prairie Pothole Region, USA. Surface-water levels, along with primary components of the wetland water balance, were monitored at four wetland catchments over 3 years. During the second year of the study, subsurface drainage systems were installed in two of the wetland catchments using drainage setbacks, and the drainage discharge volumes were monitored. A catchment water-balance model also was used to assess the potential effect of subsurface drainage (i.e., reduced precipitation runoff) on wetland hydrology, and to assess the efficacy of drainage setbacks for mitigating these effects. These data directly support...

Acoustic telemetry is a popular tool for the study of fish spatial ecology. In acoustic telemetry, fish are captured, surgically implanted with an acoustic transmitter or ‘tag’, and then released back into the environment. Networks of autonomous, stationary receivers then are used to track the movements of tagged individuals over long periods of time (> 1 year). Each acoustic receiver records the date, time, and unique transmitter code (or ID) for each acoustic tag detection. This data set contains detection data for 282 acoustic-tagged lake sturgeon that were captured and released into the Detroit River, St. Clair River, and Lake Huron between 2011 and 2015. Movements of acoustic-tagged individuals were tracked...

Diet contents of Deepwater Sculpin (Myoxocephalus thompsonii) were identified, enumerated, and measured to monitor the changes in the offshore benthic fish community within Lake Huron. Collections were made using a 21-m headrope with a 4.76mm square mesh cod-end with 10 minute contour trawl tows.. Deepwater Sculpin collected from the USGS fall forage (2003-2005 and 2010-2014) were counted and weighed en masse on board research vessel. Individual weights (nearest 0.001g) and measurements (0.1mm) were conducted in laboratory setting. Stomachs were extracted in laboratory setting (from esophogus to pyloric ceaca). Stomachs were stored in ethanol for later dissection. Stomach contents were removed in petri dish. All...

Data Release for Report describes surface-water nutrient concentrations from multiple sites on the Conasauga River in northern Georgia in comparison with rivers in adjacent watersheds.

This tabular data set contains information about the diets of double-crested cormorants (Phalacrocorax auritus) collected from Saginaw Bay, Lake Huron during April-September 2013 and 2014. Diet items were identified, enumerated, and measured.

This is a tabular data set that contains morphological and experimental data for a study testing if silver stage American eel respond to each other's odor. Inside a laboratory flume, downstream-swimming eels were exposed to both live (putative attractant) and dead (putative repellent) conspecific washings to determine whether their trajectory of downstream movement, level of activity, or time spent inside targeted areas of the arena changed after exposure. One CSV file contains eel morphological data and the other CSV file describes behavioral responses.
