Data

The data being released were part of a project funded by the United States Environmental Protection Agency (USEPA). This study sought to identify the bacterial and planktonic communities (cyanobacteria, eukaryotic algae) potentially contributing to eutrophication within the Grand Calumet River Area of Concern (AOC) in northern Indiana along the southern shore of Lake Michigan. In 2021...

Data represent physical (water quality) and biological (fish, macroinvertebrate, and vegetation community) collections as indicators for Pool 1A and the Maankiki Marsh North and South units at the Shiawassee National Wildlife Refuge in Saginaw, MI, USA. The Maankiki North and South units were recently reconnected to the Shiawassee River in 2018, whereas Pool 1A represents a historically

Annual spring (May) and fall (late October through early November) gillnet assessment surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in northern Lake Michigan, including the Northern Refuge, between 1998-2024. Total length, weight, sex, maturity, and sea lamprey wounds were recorded for each lake trout and burbot caught in the gill nets. Lake trout...

These data describe demographic, diet contents and associated weights, fullness index, morphometrics (body shape), and meristic (total number of gill rakers) measurements of cisco (Coregonus artedi) collected in Lake Michigan along the eastern shoreline, the Pine River/ Lake Charlevoix Channel, and from three drowned river mouth lakes (Portage Lake, Muskegon Lake, Lake Charlevoix) from...

Acoustic Telemetry is gaining popularity for use in fisheries research as a method to estimate survival and observe behaviors of native fish species. Methodology for capture and tagging of fish is typically context and species-specific, requiring a case by case basis for best practices to maximize survival of tagged individuals. This dataset includes acoustic detection data from 320...

This data set includes information on algae community composition and metadata for fish environmental DNA (eDNA) samples collected along the shoreline of southern Lake Michigan in late August 2024. Washed up, floating, and attached algae were collected along shore and in wadable water. Algal community observations were performed by microscopy to determine primary and secondary dominance...

This dataset contains Mysis count and length measurements from vertical whole-column net tows along a depth gradient in Lake Ontario and associated operation data. Sample dates occurred during August 2021 and June, July, and August 2022. Site depths ranged from 70 to 202 meters bottom depth. Sites were sampled using a paired day-night sampling approach. At each visit, the net was lowered...

The data includes dates, places, and times of sampling events for eggs of invasive Grass Carp (Ctenopharyngodon idella) in tributaries to the Great Lakes in 2014, 2023 and 2024. Reference data on locations and dates sampled, gears used, and effort are included. Developmental stages for a subset of undamaged, fertilized eggs are provided. Tables include common fields to allow for...

The data being released were part of a project funded by the Section 40804 Ecosystem Restoration of the Bipartisan Infrastructure Law (PL-117-58) in support of advancing a national revegetation effort. Data included are from a series of DNA degradation experiments targeting the mitochondrial 16S rRNA gene of the European honeybee (Apis mellifera). This study sought to determine how...

This dataset records Cladophora and associated benthic algae, collectively the Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2023 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting...

This dataset is the result of coordinated efforts to compile data associated with stocking events for whitefishes and ciscoes (members of the Coregoninae subfamily) of Great Lakes origin. The dataset includes more than 4,700 records associated with coregonine stocking, from over 150 information sources, spanning the years 1870 - 2022. The compiled information includes species, quantities...

Lake sturgeon (Acipenser fulvescens) have experienced large population declines due to overfishing, habitat degradation, and pollution. Due to these factors, lake sturgeon were extirpated in the Maumee River watershed (Ohio, USA). In 2018, a 20-year reintroduction program began that aims to establish a self-sustaining population in the Maumee River. To understand the potential success of...
