This data set includes taxonomic data for zooplankton, larval fish, and phytoplankton sampled in Little Holland Tract and Liberty Island Conservation Bank, in the northern Sacramento-San Joaquin River Delta, California. Zooplankton and larval fish were collected with target specific trawl nets and phytoplankton was collected from water grabs. This data release includes all measured environmental parameters.
These data consist of larval fish and water profile data collected with a nearshore to offshore transect approach at 9 transects throughout Lake Huron. Larval fish and their stomach contents were identified, enumerated, and measured (if possible) using a dissecting microscope. These data were used to calculate densities of potential fish prey items (what is available in the environment) and compare that to what the fishes ate for selectivity analysis. Larval fish age estimation based on daily growth rings from otoliths was also conducted. These data are in raw form. The water profile data were collected using a bathythermograph and bin-averaged at the 1 m level. Environmental prey data are available at the following...
Between 1900 and 1932, a copper (Cu) mine operated near Gay, Michigan, along the shore of Lake Superior, discharged approximately 22.8 million metric tons of waste material known as ‘stamp sands’ (SS) to a nearby beach. This pile of SS has migrated via wind and rain along the beaches in northern Grand Traverse Bay and into Buffalo Reef, an important spawning area for Lake Trout and Lake Whitefish. During their first summer, these newly spawned fish consume benthic invertebrates and zooplankton in nearby beach habitats. SS contain elevated concentrations of metals (especially Cu) that are toxic to many invertebrate taxa, and studies have observed very few benthic taxa in areas with very high SS. Here, we sampled...

These data were compiled as part of a long-term (1964 - 2022) water quality monitoring program at Lake Powell. Objectives of our study were to release a consistent record of long-term water quality data. The 58-year limnology dataset captures some water quality parameters (temperature, salinity, major ions, total suspended solids) from reservoir filling to present day. It also contains a 38-year record of secchi depth, and a ~30-year record of nutrients, phytoplankton, and zooplankton assemblages. The data were collected from various sites within the Lake Powell reservoir and the Glen Canyon dam. Regular monthly sampling occurred at three sites near the dam and reservoir-wide sampling was generally conducted quarterly,...

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,...

Malheur Lake is a shallow, freshwater lake in southeastern Oregon. This data release includes phytoplankton data from three sites located in Malheur Lake collected from 8/8/2018 to 8/11/2020. For each sample collected, the phytoplankton were reported to the lowest taxonomic unit. Phytoplankton biovolume, algal cell concentration, and algal biomass concentration are included. All phytoplankton data were generated by PhycoTech, Inc. The dataset includes two comma-separated values (.csv) files and metadata. The first CSV file includes all of the taxonomic, biovolume, and density information. The second CSV file includes the 111 unique taxa identified.
Mono Lake is a hypersaline soda lake rich in dissolved inorganic arsenic with its primary production currently dominated by Picocystis str. ML. We set out to determine if this picoplankter could metabolize inorganic arsenic, and in doing so form unusual arsenolipids (e.g., methylated arsinoyl ribosides) as reported in other saline ecosystems and by halophilic algae. We cultivated Picocystis str. ML on an inorganic seawater-based medium with either low (37 µM) or high (1,000 µM) phosphate in the presence of arsenite (~0.4 mM), arsenate (~0.8 mM), or without arsenic additions.

This data release contains a 17-year record (2005-2022) of discrete chlorophyll data from inland waters, collected from across the nation and territories. These data are from discrete samples (collected in the field and analyzed in the laboratory) from plankton (suspended algae) and periphyton (benthic algae) from lakes, streams, rivers, reservoirs, canals, and other sites. These data are gathered to support process and remote sensing modeling and prediction of Harmful Algal Blooms (HABs). The chlorophyll data were compiled from the Water Quality Portal (WQP) and USGS National Water Quality Lab (NWQL). Data for uncorrected chlorophyll a, corrected chlorophyll a, and pheophytin from EPA Methods 445 and 446 are included...

This dataset includes field and lab data for fish, vegetation, zooplankton, phytoplankton, fish diets, and stable isotopes collected during daylight hours in the Sacramento Deep Water Shipping Channel in the Northern Sacramento-San Joaquin Delta, California, USA. This data release includes all measured environmental parameters, animal taxa, and isotope values included in the analysis.
The U.S. Geological Survey (USGS) Data Release provides phytoplankton data from eight sites located in Upper Klamath Lake, OR from 6/28/2010 to 9/19/2018. Phytoplankton data are reported to the lowest possible taxonomic level and biovolume, biomass, and density are reported.
This data release presents the results of analyses of biota and water samples collected on multiple dates from 2007 to 2014 at 3 locations in Lake Mead National Recreation Area. Data are presented in 3 spreadsheets containing sample analyses for (1) stable isotopes in biota (2007-2014), (2) synthetic organic compounds in biota (2013-2014), and (3) synthetic organic compounds in water (2013-2014)

Crustacean zooplankton were collected, enumerated, identified, and measured within the St. Clair-Detroit River System (SCDRS). Collections were made using a 0.5 m diameter 153 um zooplankton net. Nets were lowered to ~0.5 m from bottom depth and retrieved. Nets were utilized with a General Oceanics flowmeter to calculate the distance the net traveled. At sites of collection, both temperature (degrees C) and Secchi depth (m) were collected for abiotic influencing factors of the zooplankton community. Collected specimens were narcotized in sugar formalin. Specimens were enumerated, identified, and measured under a dissection microscope. Volumetric estimates (m^-3) were obtained by applying the distance traveled and...

This data includes information on water quality, zooplankton, and fish sampled in ponds on delta islands in San Joaquin County, California. The islands include Bacon (North and South ponds), Bouldin (East and West ponds), Holland Tract (Middle, North, and South ponds), and Webb Tract (East, Middle, and North ponds). Discrete water quality parameters were measured bimonthly and continuous temperature was recorded every 15 minutes. Zooplankton were sampled monthly using a Schindler-Patalas 12L plankton trap with a 200mL Dolphin bucket with 61 micron stainless mesh. Fish were sampled once at each pond using beach seines, gill nets, and boat electrofishing gear.
