Survey data of larval fish, zooplankton, and aquatic plants collected from the St. Clair River delta, MI (2010-2011) Survey data of larval fish, zooplankton, and aquatic plants collected from the St. Clair River delta, MI (2010-2011)
The St. Clair River delta, part of the St. Clair-Detroit River System (SCDRS), is the most fished coastal wetland area in the Laurentian Great Lakes and provides nursery habitat for a variety of fish species; however, few large-scale surveys of early fish life stages have been performed since the 1980s. Larval fish, zooplankton, and aquatic plants were sampled at 21 sites in delta...
Polychlorinated biphenyl concentrations in adult walleye from the Fox River (Wisconsin) population, 2014 Polychlorinated biphenyl concentrations in adult walleye from the Fox River (Wisconsin) population, 2014
Adult walleye (10 females and 10 males) were caught in Fox River (Wisconsin) during April 2014. Total length, weight, and age were determined for each of the walleye. Whole-fish homogenates were prepared during 2017. Lipid concentration and polychlorinated biphenyl (PCB) congener concentrations were determined in each of the homogenates during 2017-2018. For each sample, PCB congener
Fox River walleye mercury isotope data Fox River walleye mercury isotope data
Adult walleye were caught in Fox River (Wisconsin) during April 2014. Age-0 walleye were caught in Fox River during October 2014. Total length, weight, age, and proportion of weight represented by water were determined for each of the walleye. Whole-fish homogenates were prepared during 2014-2015 and during 2017. Total mercury (HgT) concentration, methylmercury (MeHg) concentration, and...
Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River in 2017 Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River in 2017
Grass Carp Ctenopharyngodon idella was imported to the United States in the 1960s for research into its usefulness as a biocontrol agent for nuisance aquatic vegetation. Escapees and intentionally stocked individuals founded wild, spawning populations in the Mississippi River and tributaries to the Laurentian Great Lakes. USGS-led research on the Sandusky River, a tributary to Lake Erie
16S rRNA gene sequencing and E. coli for shorelines and the Grand Calumet River, Indiana, 2015 16S rRNA gene sequencing and E. coli for shorelines and the Grand Calumet River, Indiana, 2015
Data were collected in August and September 2015 for analysis of bacteria communities of the Grand Calumet River and associated shorelines. Water samples were collected on three occasions corresponding to one rain-related (wet) events and two non-rain (dry) events. Water samples were collected in the Grand Calumet River, at the mouth of the river, at offshore locations around the...

Identify sources of high E. coli concentrations, Grand Calumet River Area of Concern beaches of southern Lake Michigan, 2016-2018 Identify sources of high E. coli concentrations, Grand Calumet River Area of Concern beaches of southern Lake Michigan, 2016-2018
Data were collected as part of a study to identify sources of E. coli contamination at several beaches located in the Grand Calumet River Areas of Concern, located in northern Indiana on Lake Michigan. The study was funded by the Great Lakes Restoration Initiative. Water samples were collected at each site (Jeorse Park 1, Jeorse Park 2, Hammond East, Hammond West, Whihala West, Whihala...
Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Plots Points and Photographs Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Plots Points and Photographs
The Mojave Plots Points data are 1,219 plot locations in the Central Mojave Desert where field data were recorded and photographs were taken from 1997-1999 to provide context for the classification of the Central Mojave Desert into various vegetation classes. The 1,219 plot locations in the plots points shapefile (plots_points.shp) are each assigned a unique identifier called the...
Sclerochronology of Walleye Dorsal Spines, 2011-2016 Sclerochronology of Walleye Dorsal Spines, 2011-2016
This data release includes both a tabular data set and a zipped file of images. The tabular data set consists of measurements of annuli widths from Walleye dorsal spine thin sections. Walleye spines were sampled non-lethally from fish that were selected for acoustic telemetry tag implantation in several interrelated investigations. The telemetry work was coordinated through the Great...
Diel activity of newly metamorphosed juvenile sea lamprey in Carp River, MI 2011, Morpion Stream, Quebec 2014, and an artificial stream at Hammond Bay Biological Station 2014-2015 Diel activity of newly metamorphosed juvenile sea lamprey in Carp River, MI 2011, Morpion Stream, Quebec 2014, and an artificial stream at Hammond Bay Biological Station 2014-2015
These data contain biodata, net catch, and detection records for juvenile sea lamprey sampled in natural streams in Michigan and Quebec, Canada and those stocked into an artificial stream at the USGS Hammond Bay Biological Station for monitoring diel activity. During October 31 through November 9, 2011 scientists collected downstream migrating juvenile sea lamprey from the Little Carp...
River Channel Survey Data, Redwood Creek, California, 1953-2013 River Channel Survey Data, Redwood Creek, California, 1953-2013
Dr. Richard Janda of the USGS began a channel monitoring program in Redwood Creek in northern coastal California in 1973. The USGS continued this work through 2013, when the Research Geologist, Dr. Mary Madej retired. This effort produced 40 years of channel change data in rivers that were disrupted by severe erosion following timber harvest of old-growth redwood forests, a portion of...
Native and Invasive Species Plant Growth and Mortality in Growth Media Inoculated with Bacteria Found on Phragmites From New Jersey (2016) Native and Invasive Species Plant Growth and Mortality in Growth Media Inoculated with Bacteria Found on Phragmites From New Jersey (2016)
Bacteria were isolated from seeds of non-native Phragmites australis (haplotype M) then representatives were evaluated for their capacities to become intracellular in root cells, and their effects on: 1.) germination rates and seedling growth, 2.) susceptibility to damping-off disease, and 3.) mortality and growth of competitor plant seedlings (dandelion (Taraxacum officionale F.
