Data

These data consist of juvenile lake trout biological and diet information collected from USGS bottom trawl, beam trawl, and gillnet surveys in Lake Michigan from 2015-2017 and 2019-2022. All prey were identified, enumerated and weighed. Only fish prey and Mysis had lengths measured.

The data being released were part of a project funded by the United States Environmental Protection Agency (USEPA). This study sought to identify the 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, triplicate...

This data set, compiled by the USGS Lake Erie Biological Station, provides near-bottom measurements of temperature and dissolved oxygen for the Central Basin of Lake Erie. Data were recorded by self-contained environmental data loggers (PME, Inc., MiniDOT data loggers). The data loggers were deployed to collect data during August 2021 through November 2022 to better understand how...

This data release includes early life stage data for Lake Ontario fishes including egg deposition, larval fish emergence from varied substrates and depths, and horizontal larval fish tow surveys conducted across various habitats. Tables include data from multiple field surveys and lab studies from 2018, 2019, and 2021. Larval tow observations from 2018 are from lake wide sampling in Lake...

Data represent physical (water quality, water nutrient analysis) and biological (fish, macroinvertebrate, and vegetation community) collections from the Shiawassee National Wildlife Refuge in Saginaw, MI, USA (specifically, historical management unit "Pool 1A" and the North and South management units of the Maankiki Marsh Complex.) The North and South management units of the Maankiki...

To determine the potential for controlling non-native Phragmites australis through use of a cut-to-drown management strategy we performed a controlled greenhouse mesocosm experiment in Ann Arbor, MI during summer 2021. Field collected Phragmites rhizomes from one site within Michigan were propagated, cuttings taken of individual stems and potted in nursery pots. Established plants were...

Acoustic seabed classification (ASC) is an important method for understanding landscape-level physical and biological patterns in the aquatic environment. Bottom habitats in the Laurentian Great Lakes are poorly mapped to date, and will require a variety of contributors and data sources to complete. We repurposed a long-term split-beam echosounder dataset gathered for purposes of...

These data were derived from hydroacoustic data collected by uncrewed surface vehicles (USVs) and powered research vessels. The powered vessels overtook the USVs in Lakes Huron and Michigan to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into three depth groups (epilimnion, metalimnion, hypolimnion) for analysis. Each drone...

This dataset maps the connectivity and bottlenecks among habitat patches within a six-kilometer ribbon along the United States terrestrial coastline of the Great Lakes. Each pixel represents the relative value that cell contributes to connectivity between and among habitat patches. When aggregated the pixel values produce a map of all possible pathways between habitat patches providing...

This dataset maps the connectivity and bottlenecks among protected areas within a six km ribbon along the terrestrial coastline of the U.S. Great Lakes. Each pixel represents the relative contribution that cell provides to connectivity between and among the protected areas. When aggregated the pixel values produce a map of all possible pathways between protected areas, providing the end...

Subadult and smolt behavioral data were compiled by Ali Mokdad from Trevor Pitcher's lab at the University of Windsor, Ontario, Canada. Data are comprised of fish reactions in choice flume video data (attractance/avoidance) collected by Jeremy Kraus at Tunison Lab of Aquatic Science, August 2021 and February 2020 respectively. Atlantic salmon were exposed/not exposed to imprinting...

Freshwater lake and stream fish data were collected as part of cooperative project between the U.S. Geological Survey and the U.S. National Park Service which began in 2021. Data was primarily collected from 22 sites within the Pictured Rocks National Lakeshore. The number of sites sampled each year as well as the types of data collected and sampling methods varied during each visit...
