From August 2018 to October 2019, the U.S. Geological Survey collected spatially high-resolution water quality data as part of five shoreline synoptic surveys around the perimeters of Owasco, Seneca, and Skaneateles Lakes within the Finger Lakes Region of New York. Water-quality data were collected just below water surface utilizing YSI EXO2 multiparameter sondes and portable nitrate sensors paired with real-time GPS data as part of a HABs monitoring program in the Finger Lakes. In October 2019, water-quality data collection was paired with discrete phytoplankton grab samples on Owasco Lake and Seneca Lake. Phytoplankton grab samples were collected just below water surface with a peristaltic pump at twelve locations...

This child item data set provides phytoplankton data collected from Owasco Lake, New York, on October 8, 2019. Phytoplankton were identified to the lowest possible taxonomic level, and abundance (density reported as both natural units and cells) and biovolume are reported. All data are reported as raw calculated values. This dataset includes all routine and quality assurance/quality control samples collected at twelve sampling locations on Owasco Lake.

An interdisciplinary and multiagency study was conducted in southern Florida to examine harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains from Lake Okeechobee to the west into the Gulf of Mexico. Using in-situ mesocosm experiments, ammonium, nitrate, phosphate, and urea were altered from ambient conditions to determine the effects on cyanotoxin biosynthesis gene presence and quantity as measured via quantitative polymerase chain reaction (qPCR). Eight experiments were conducted seasonally from May 2019 through July 2021 at the W.P. Franklin Lock and Dam. The experimental installations consisted of three floating metal cradles each containing four opaque fiberglass chambers filled with...

As harmful algal blooms (HABs) increase in magnitude and duration worldwide, they are becoming an expanding threat to marine wildlife. Over the past decade, domoic acid (DA) and saxitoxin (STX) have been increasingly problematic bicoastally in the United States. We investigated pooled seabird mortality data from opportunistic sampling events between 2007-2018, across three states, to examine the patterns and role of DA and STX in seabird mortality events from the continental United States. Patterns in DA and STX levels and affected tissue type were reviewed, and two specific accounts of localized and pervasive event types were examined. There has been increased toxin detection with expanded tissue testing during...

This data release presents two calibration datasets that relate aquatic reflectance derived from Sentinel-2 satellite imagery with algal bloom conditions in the Brownlee Reservoir on the Idaho Oregon border. These datasets were developed to evaluate remote sensing methods for identifying algal blooms in Brownlee Reservoir like those from July 2022 that are illustrated in field photo (left) and satellite imagery (right) in “Picture1.png”. The first calibration dataset includes satellite-based spectra paired with chlorophyll-a concentrations in micrograms per liter analyzed by the Bureau of Reclamation Soil and Water Laboratory with standard method 10200 H.2 on water samples collected within 2 m of the surface by...

This child item data set provides phytoplankton data collected from Seneca Lake, New York between October 9-10, 2019. Phytoplankton were identified to the lowest possible taxonomic level, and abundance (density reported as both natural units and cells) and biovolume are reported. All data are reported as raw calculated values. This dataset includes all routine and quality assurance/quality control samples collected at twelve sampling locations on Seneca Lake.

The Bonnet Carré Spillway (BCS), located about 28 miles northwest of New Orleans, Louisiana, was constructed in the early 1930s as part of an integrated flood-control system for the lower Mississippi River Plain. The BCS is designed to divert water from the Mississippi River (MSR) into Lake Pontchartrain (LP), which then flows into Lake Borgne and the Mississippi Sound (MS Sound), thus relieving pressure on levees downstream. Opening of the spillway occurs when measured streamflow in the MSR at New Orleans exceeds approximately 1.25 million cubic feet per second, which normally occurs once a year in late spring. In 2019, for the first time, the spillway opened twice in one year; the first opening occurred between...
Quantitative polymerase chain reaction (qPCR) data were compiled for the biosynthesis genes of five toxins of interest produced by cyanobacteria as well as an internal control. Sample deoxyribonucleic acid (DNA) were collected from 21 sites which includes 17 sites from Lake Okeechobee, and four sites from the Caloosahatchee River and the St. Lucie River. Samples were collected on a monthly basis from March 2019 through October 2021, provided water levels were high enough for a sample to be collected. Samples from Lake Okeechobee were collected by the South Florida Water Management District (SFWMD) and samples from the Caloosahatchee and St. Lucie Rivers were collected by the U.S. Geological Survey (USGS). Environmental...
