This dataset provides results of a targeted bacterial community metagenomic analysis of surface water, groundwater, and sand samples at Jeorse Park on Lake Michigan in East Chicago, Indiana. Seventy-two samples were collected from 6 sites in 2017. Samples were analyzed for the 16S ribosomal RNA (16S rRNA) gene (the S in 16S refers to the rate of sedimentation, in Svedberg units, of the RNA molecule in a centrifugal field), and one sample was excluded because it produced too few reads. The 16S rRNA gene is the most conserved of three rRNA genes (16S, 23S, and 5S) and is considered the most reliable for identification and taxonomic classification of bacterial species (Bouchet and others, 2008). Taxonomic analysis...

The overarching goal of this research was to use site-specific data to develop local and regionally-applicable climate change models that inform management of tidal wetlands along the Pacific Northwest coast. The overarching questions were: (1) how do tidal marsh site characteristics vary across estuaries, and (2) does tidal marsh susceptibility to sea-level rise (SLR) vary along a latitudinal gradient and between estuaries? These questions are addressed in this data collection with three specific objectives: (1) measure topographical and ecological characteristics (e.g., elevation, tidal range, vegetation composition) for tidal marsh and intertidal mudflats, (2) model SLR vulnerability of these habitats, and (3)...

In California, the near-shore area where the ocean meets the land is a highly productive yet sensitive region that supports a wealth of wildlife, including several native bird species. These saltmarshes, mudflats, and shallow bays are not only critical for wildlife, but they also provide economic and recreational benefits to local communities. Today, sea-level rise, more frequent and stronger storms, saltwater intrusion, and warming water temperatures are among the threats that are altering these important habitats. To support future planning and conservation of California’s near-shore habitats, researchers examined current weather patterns, elevations, tides, and sediments at these sites to see how they affect...

Description of WorkThe success of GLRI beach restoration projects must be assessed to determine whether goals of recipients are on track and identify any developing unforeseen consequences of restoration efforts. Implementation of multiple BMPs during restoration can make understanding the impacts of individual BMPs difficult. However, proper site selection and well-designed monitoring and assessment plan can overcome such difficulties. The urban beaches chosen for evaluation are at various stages of the restoration process and located in Indiana (Jeorse Park Beach), Illinois (63rd Street Beach), and Wisconsin (North Beach). Data used for evaluation include continuous monitoring and synoptic mapping of nearshore...

Water-quality data collected in this area included three-dimensional measurements of water temperature, specific conductance, pH, dissolved oxygen, chlorophyll, and phycocyanin (blue-green algae). The water-quality data were measured at 1-second intervals and were geo-referenced...

Description of Work The GLRI Rivermouths Project (template 82) is designed to enhance our understanding of how rivermouths function at both regional and local scales by 1) developing a rivermouth classification system, based on a broad scale database covering all Great Lakes rivermouths (>2000); 2) creating a science-based understanding of how the ecological structure and function of rivermouths are linked both to the landscapes they drain and to the Lakes with which they mix; and 3) increasing the public and scientific profile of these ecosystems by connecting researchers and natural resource managers through a collaborative dialog. The long-term goal is to provide enhanced guidance for restoration and rehabilitation...

Water velocities were measured along planned survey lines, which were generally perpendicular to the shoreline and spaced 100 meters apart, over an approximately 2.3-mile section of nearshore Lake Erie on June 10-12, 2019 (survey 1), and August 19-21, 2019 (survey 2), using a 1200 kHz acoustic Doppler current profiler (ADCP). The data were geo-referenced with an integrated global navigation satellite system (GNSS) smart antenna with submeter accuracy. The ADCP and GNSS antenna were mounted on a marine survey vessel, and data were collected as the survey vessel traversed the lake along planned survey lines. There was a total of 43 survey lines which typically started about 50 meters offshore and ended 500 meters...

The U.S. Geological Survey (USGS), in cooperation with the Great Lakes Restoration Initiative, collected data in 2017 to study the sources and occurrences of continual detections of high Escherichia coli (E. coli) detections at urban beaches along the Lake Michigan shoreline in northwest Indiana and northeastern Illinois. High E. coli detections cause the beaches to be closed for recreational use until additional samples verify that E. coli levels have fallen below the threshold of 235 counts per 100 ml. The project used microbial source tracking (MST) and metagenomics analyses to evaluate the sources of E. coli. This data release provides the phytoplankton, mictobial source tracking, and metagenomics components...

Description of Work A Department of Interior team, including U.S. Geological Survey (USGS), Fish and Wildlife Service (FWS), and National Park Service (NPS), is working to determine why botulism outbreaks, which have killed large numbers of fish and fish-eating birds, are occurring in the Great Lakes. This project will determine: 1) a quick assay test for the presence of the toxin , 2) how birds are exposed to the toxins, and 3) what factors combined trigger an outbreak. This information will be used to formulate management strategies. Botulism intoxication is caused by ingestion of neurotoxins produced by the bacterium Clostridium botulinum. Periodic outbreaks of type E botulism have resulted in die-offs of fish...

Description of Work Since the early 2000s, the LaMP has proposed adding nutrients (specifically phosphorus) to its “pollutant of concern” list, given that excessive nutrients were believed to cause impairments in the nearshore waters. Since that time, scientists have highlighted the “shunting” of nutrients to the nearshore, owing to the ability of invasive dreissenid mussels to capture some portion of allochthanous phosphorus that enters the lake through tributaries. These changes are believed to underlie a series of changes in the nearshore, including increased biomass of cladophora and hypothesized increases in benthic and pelagic biomass, including zooplankton and fish. As an extension, this model proposes the...

The Lakewide Management Plans (LaMPs) within the Great Lakes region are examples of broad-scale, collaborative resource-management efforts that require a sound ecosystems approach. Yet, the LaMP process is lacking a holistic framework that allows these individual actions to be planned and understood within the broader context of the Great Lakes ecosystem. To help this issue, a conceptual framework for Lake Michigan Coastal/Nearshore Ecosystems was developed to address for major LaMP goals; Can we drink the water?, Can we eat the fish?, Can we swim in the water?, Are all habitats healthy, naturally diverse, and sufficient to sustain viable biological communities?
