Water velocities and water-quality constituents were measured along planned survey lines, which were generally perpendicular to the shoreline and spaced 100 meters apart, over an approximately 2.3-mile section of nearshore Lake Erie on June 10-12, 2019 (survey 1), and August 19-21, 2019 (survey 2), using a 1200 kHz acoustic Doppler current profiler (ADCP), a YSI 6920 V2 multiparameter sonde, and a YSI EcoMapper autonomous underwater vehicle (AUV). Water-quality data collected in this area included near-surface and three-dimensional measurements of water temperature, specific conductance, pH, dissolved oxygen, turbidity, chlorophyll, and phycocyanin (blue-green algae). The data were geo-referenced with an integrated...

Velocity and water-quality surveys were completed along an approximately 71-mile reach of the Ohio River between Markland Locks and Dam (river mile 531.5) and McAlpine Locks and Dam (river mile 606.8) on October 27–November 4, 2016 (survey #1), and June 26–29, 2017 (survey #2). Water-quality data collected in this reach included surface measurements and vertical profiles of water temperature, specific conductance, pH, dissolved oxygen, turbidity, chlorophyll, and phycocyanin. Streamflow and velocity data were collected simultaneous to the water-quality data at cross-sections and along longitudinal lines (corresponding to the water-quality surface measurements) and at selected stationary locations (corresponding...

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the St. Lucie and Caloosahatchee Rivers in October 2017, Lake Okeechobee and the Caloosahatchee River in July 2018 and the Caloosahatchee River, St. Lucie River and Lake Okeechobee in August of 2018, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescence of dissolved organic matter were recorded at 5 second intervals and nitrate+nitrite was recorded at 1 minute intervals during water-quality surveys in order to create high resolution water-quality maps of the study area.
Here we archive data collected during a nitrogen addition field experiment in the Sacramento River Deep Water Ship Channel. Calcium nitrate was added on 8 dates to a segment of the ship channel centered at Navigation Light 74. Prior to and following the nutrient additions, we collected water samples and sensor-based measurements at 7 sites between Navigation Light 70 and 76. Water samples for nutrient analyses were collected in 500 mL High Density Poly Ethylene (HDPE) amber containers from 1 m and 8 m depths using a peristaltic pump. Whole water samples for phytoplankton analysis were collected from 1 m depth in 500 mL clear HDPE containers and immediately preserved with 20 mL of Lugol’s iodine solution (Lugol’s,...

Extended time-series sensor data were collected between 2012 and 2016 in surface water of a tidal salt-marsh creek on Cape Cod, Massachusetts. The objective of this field study was to measure water chemical characteristics and flows, as part of a study to quantify lateral fluxes of dissolved carbon species between the salt marsh and estuary. Data consist of in-situ measurements including: salinity, temperature, pH, dissolved oxygen, redox potential, fluorescent dissolved organic matter, turbidity and chlorophyll. Surface water flow, water level and water elevation data were also measured. The data provided in this release represent a compiled data set consisting of multiple sensor deployments between 2012 and 2016.

This U.S. Geological Survey (USGS) data release provides continuously-measured water-quality data collected from two sites on Milford Lake, Kansas, during July 26-27 and August 30-31, 2015. All data are reported as raw measured values and are not rounded to USGS significant figures. Water-quality monitors were used to measure water temperature, specific conductance, turbidity, pH, chlorophyll, phycocyanin, and dissolved oxygen at fifteen-minute intervals. This dataset includes all continuously measured data collected at two short-term, fixed-site locations as part of a study to evaluate the spatial variability of harmful algal blooms in Milford Lake, Kansas.

This U.S. Geological Survey (USGS) Data Release provides selected discretely measured water-quality data collected from 27 monitoring sites in Johnson County, Kansas, during January 2015 through June 2016. Water-quality samples were analyzed for nutrients, Escherichia coli bacteria, total suspended solids, suspended-sediment concentration, and chlorophyll as part of a study to assess the water-quality program for total maximum daily loads in Johnson County, Kansas. Samples were analyzed by the Johnson County Environmental Lab, Johnson County, Kansas, USGS National Water Quality Laboratory, Lakewood, Colorado, and USGS Kansas Water Science Center, Lawrence, Kansas.
The dataset includes water-quality sensor readings collected by the U.S Geological Survey (USGS) from the Caloosahatchee River at the Franklin Lock and Dam and 12 open-air fiberglass tanks filled with Caloosahatchee River water used for mesocosm experiments testing the effects of elevated nutrients on harmful algal bloom (HAB) dynamics. This dataset contains water quality sensor readings from two of eight total independent experiments conducted from June 8-11, 2020 and September 14-17, 2020. Each of the 12 tanks were randomly treated with either ammonium hydroxide, sodium nitrate, sodium phosphate, or left untreated (controls) for a total of three replicates of each treatment. The tanks were treated with incrementally...

Includes: Seasonal data on Zooplankton - biomass data were obtained from the COPEPOD database (NOAA) for 1977-2007, Chlorophyll - measured to determine phytoplankton concentration, Sea Surface Temperature - data were extracted from three dimensional climatologies representing 28 years from 1980 - 2007, averaged, and interpolated with ordinary kriging to produce a smooth surface, and Stratification - data helps describe the physical environment of the water column near the surface. These data help to understand the seasonal patterns of mixing and stratification that help to determine areas of high productivity and benthic-pelagic coupling.

Optical measurements collected from the Colorado River, near Lees Ferry, Arizona, September 23, 2019
To support an investigation of the feasibility of measuring river bathymetry using a polarizing lidar sensor, optical measurements were collected from the Colorado River near Lees Ferry, Arizona on September 23, 2019. Optical measurements were collected with a WET Labs ECO which measures the turbidity and concentration of colored dissolved organic matter (CDOM) and chlorophyll. Absorption and attenuation coefficients were collected with a WET Lab ac-s instrument.
