In cooperation with the Texas Commission on Environmental Quality (TCEQ), the U.S. Geological Survey (USGS) used various field and laboratory methods to determine the presence and concentration of cyanobacteria, cyanotoxins, and taste-and-odor compounds in selected Texas water bodies. This data release documents the results from water-quality samples collected from 12 water bodies in Texas during water year 2020 (WY20) and 2021 (WY21). A water year is defined as the 12-month period from October 1 through September 30 and is designated by the calendar year in which it ends. Both qualitative and quantitative field and laboratory methods were performed. Analyses included phytoplankton taxonomy, measurements of phytoplankton...
This dataset contains tabulated-data of dissolved oxygen concentrations collected at Levittown Lake, Toa Baja, Puerto Rico. The standard light-dark method was used to determine the primary productivity in phytoplankton. The method consists in the in-situ incubation of two light-and-dark bottles for approximately four hours. Dissolved oxygen concentrations were estimated using the Winkler method. A total of twelve in-situ incubations were conducted on a monthly basis from April 2010 to June 2011. For each bottle incubated, two or three titrations were conducted and an average of the dissolved concentrations is calculated.

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.

During two seasonal sampling events in spring (June) and fall (August) of 2015, the U.S. Geological Survey, in cooperation with the Illinois Department of Natural Resources and the U.S. Environmental Protection Agency, collected benthos (benthic invertebrates) and plankton (zooplankton and phytoplankton) at three sites each in the Waukegan Harbor Area of Concern (AOC) in Illinois and in Burns Harbor-Port of Indiana, a non-AOC, in Indiana. Physical and chemical data were sampled concurrently (specific conductance, temperature, pH, dissolved oxygen, chlorophyll-a, total and volatile suspended solids in water samples; particle size and volatile-on-ignition solids of sediment in benthic grab samples). Benthos were collected...

Atmospheric nitrogen (N) deposition to lakes and watersheds has been increasing steadily due to various anthropogenic activities. Because such anthropogenic N is widely distributed, even lakes relatively removed from direct human disturbance are potentially impacted. However, the effects of increased atmospheric N deposition on lakes are not well documented. We examined phytoplankton biomass, the absolute and relative abundance of limiting nutrients (N and phosphorus [P]), and phytoplankton nutrient limitation in alpine lakes of the Rocky Mountains of Colorado (USA) receiving elevated (>6 kg N�ha?1�yr?1) or low (<2 kg N�ha?1�yr?1) levels of atmospheric N deposition. High-deposition lakes had higher NO3-N and total...

Nutrient and phytoplankton data indicate poor environmental health in four oxbow lakes in central Louisiana suggesting that long-term agriculture practices and increases in shoreline development have accelerated eutrophication. Surface-water quality and phytoplankton indicators of eutrophication were examined at Lake Bruin, Lake St. John, Lake St. Joseph, and False River Lake along an eutrophication gradient. These oxbow lakes are cut-off meanders of the Mississippi River that do not receive overbank flow from the river due to the levee system built in the early twentieth century. Oxbows have formed at various times in the last few hundred years as the Mississippi River carves a more efficient hydrologic route to...

Data was collected in the Cache Slough Complex located in the northern San Francisco Estuary to characterize water quality parameters at high spatial resolution. Data collection was conducted on three separate occasions: October 2017, May 2018, and October 2018. Data set includes nitrate, ammonium, ortho-phosphate, dissolved organic carbon, temperature, conductivity, dissolved oxygen, turbidity, chlorophyll, stable isotopes including water isotopes. Measurements were used to calculate evaporation to inflow ratios and water residence time.
Quantitative phytoplankton data was collected as part of an interdisciplinary and multiagency experimental study investigating harmful algal bloom (HAB) dynamics in the Caloosahatchee River located in southwestern Florida. Algae and cyanobacteria play crucial roles in aquatic ecosystems, but under favorable environmental conditions such as nutrient enrichment certain taxa may experience population growth booms resulting in HABs. HABs are becoming increasing common in the Caloosahatchee and the Lake Okeechobee system, yet the drivers and processes controlling these events is still under investigation. Here, three independent mesocosm experiments were conducted on the Caloosahatchee River at the W. P. Franklin Lock...
The dimensions of each organism were measured with a Whipple grid and the biovolume was estimated using the simplest geometric shape (e.g., cylinder, cone, sphere, etc.) that best fit the shape of each taxon. Shapes were assigned according to Hillebrand et al. (1999). Biovolume was calculated for the first five organisms/counting units of each taxon identified in a sample. The average biovolume was then used to calculate total biovolume of each taxon in the sample.
