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...

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)...

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...

Great Lakes Restoration Initiative,
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...
The NFHAP Coastal Spatial Framework and Indicator Datasets consist of a geospatial base layer developed in ArcGIS, and associated data fields joined to the spatial framework. The Coastal Spatial Framework is a layer of 612 distinct polygons covering coastal areas of the Continental U.S. Polygons represent either coastal watersheds (land) or coastal waters (estuaries, inshore marine, offshore marine),and are classified into six regions and 22 nested subregions. Each polygon is assigned a unique code (UniqueID) to provide location reference for indicator data, and enable joins to separate data tables.s for information recorded in the Bibliography and Assessment tables. Key indicator data fields attributed to each...

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...

Great Lakes Restoration Initiative,
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?
