Description of Work Benthos (benthic invertebrate) and plankton (phytoplankton/zooplankton) communities in Wisconsin's four Lake Michigan Areas of Concern (AOCs; Menominee River, Lower Green Bay and Fox River, Sheboygan River, and Milwaukee Estuary) and six non-AOCs will be quantified. The inclusion of non-AOC sites will allow comparison of AOC sites to relatively-unimpacted or less-impacted control sites with natural physical and chemical characteristics that are as close as possible to that of the AOCs. The community data within and between the AOCs and non-AOCs will be analyzed. This project is a cooperative agreement between the Wisconsin Department of Natural Resources (WDNR) and the US Geological Survey (USGS)....

Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

The Gulf of Alaska is one of the most productive marine ecosystems on Earth, supporting salmon fisheries that alone provide nearly $1 billion per year in economic benefits to Southeast Alaska. Glaciers are central to many of the area’s natural processes and economic activities, but the rates of glacier loss in Alaska are among the highest on Earth, with a 26-36 percent reduction in total volume expected by the end of the century. This project brought together scientists and managers at a workshop to synthesize the impacts of glacier change on the region’s coastal ecosystems and to determine related research and monitoring needs. Collected knowledge shows that melting glaciers are expected to have cascading effects...

Description of Work To date many meetings have been attended and coalitions developed between USGS Water Mission area and NYSDEC and EPA region 2 which have spun off into several other monitoring and BUI delisting projects funded by Region 2 through the USGS/EPA IA. This has been a perfect example of leveraging USGS GLRI funds to develop additional GLRI-related program for the Lake Ontario LaMP partners, especially for tributary nutrient and sediment loading to Lake Ontario and helping collect and assess the data needed to remove BUI impairments at the Rochester Embayment and St. Lawrence/Massena AOCs for benthos and phytoplankton impairments.

Rates of glacier loss in the northern Pacific coastal temperate rainforest (PCTR) are among the highest on Earth. These changes in glacier volume and extent will affect the flow and chemistry of coastal rivers, as well as the nearshore marine ecosystem of the Gulf of Alaska (GOA). Runoff from glaciers accounts for about half of the land-to-ocean movement of freshwater into the GOA, strongly influencing the freshwater and marine ecosystems along the coast. Runoff from glaciers, for example, significantly impacts the water temperature and clarity of aquatic habitats, which are important conditions for salmon reproduction. Moreover, runoff from glaciers along the GOA is an important factor in the structure of the...

Accurate estimation of evapotranspiration (ET) is essential for assessments of water balance and hydrologic responses to forest restoration treatments in uplands adjacent to the Desert LCC. As part of the Four Forests Restoration Initiative, a new paired watershed study is being planned to assess the hydrologic effects of mechanically thinning and restoring a more frequent fire regime to the ponderosa pine forests of Arizona. Water and energy balances will be measured and modeled in these paired watersheds to help inform and better plan for the hydrologic responses of future forest restoration actions. Researchers at Northern Arizona University have collected six years of eddy covariance measurements of ET in the...

Description of Work In 2011, the US EPA, USGS, and Canada’s DFO/EC continued the evolution of the strategy to conduct an “integrated’ (water quality to fish) spatially-consistent assessment for the entire lake in order to provide biomass estimates for each trophic level. A total of 54 sites were sampled during summer 2011. Water chemistry, nutrients, phytoplankton, zooplankton, benthic invertebrates, Mysis, and pelagic and benthic fish were collected at each site.

Description of Work USGS scientists provide expertise, capacity and support for the implementation of Lakewide Management Plans (LaMPs) and the associated goals, objectives and targets for each of the Great Lakes, including Lake Superior. The LaMPs are critical binational groups that are important for promoting Great Lakes restoration. Specifically, LaMP efforts include compiling monitoring and research information into the Great Lakes web mapper (SiGL Mapper). The Mapper’s focus is on information that will result in recognition of areas where data are being collected, missing or sparse, and on areas where ecosystems are vulnerable.

Description of Work Predictive models have been used at beaches to improve the timeliness and accuracy of recreational water-quality assessments over the most common current approach to water-quality monitoring, which relies on culturing fecal-indicator bacteria such as Escherichia coli (E. coli.)

Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, sport fish, and their diets to complement the seasonal lower trophic level sampling by EPA. This data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build a decision support tool that can explore how different scenarios (dreissenid control, nutrient reductions, changes in fish stocking) influence the biomass of economically important fisheries.

Description of Work The first major goal of this project is to characterize and evaluate the extent to which contaminants of emerging concern (CECs) threaten fish and other wildlife in the Great Lakes. This includes identifying and characterizing CECs in the Great Lakes Basin, identifying risk-based screening concentrations for priority CECs, evaluating population-relevant effects of complex mixtures on biota, and identifying the Great Lakes waterways at greatest risk. The second major goal of this project is to pilot and develop a short-term and an ongoing long-term state-of-the-art bioeffects surveillance program for the Great Lakes basin. This includes developing strategies which will account for variable conditions...

Description of Work The Science in the Great Lakes (SiGL) Mapper is a map-based discovery tool that spatially displays basin-wide multi-disciplinary monitoring and research activities conducted by both USGS and partners from all five Great Lakes. It was designed to help Great Lakes researchers and managers strategically plan, implement, and analyze monitoring and restoration activities by providing easy access to historical and on-going project metadata while allowing them to identify gaps (spatially and topically) that have been underrepresented in previous efforts or need further study. SiGL provides a user-friendly and efficient way to explore Great Lakes projects and data through robust search options while...

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...
Overgrazing and fire suppression have led to a loss of deep soils and vegetative cover in the 420,000 acre Alamosa Creek watershed in southwestern New Mexico. Rain and snow melt are no longer held by the soils and released slowly, but run off in floods, resulting in catastrophic flows and severe erosion that contribute sediment to Elephant Butte Dam. The diverse community of farmers that irrigate 800 acres of valley land on 49 farms in Cañada Alamosa are looking to revive traditional and develop innovate new practices to maintain their way of life. Partnerships are required to design new land management practices between scientists and local land managers. This project is a component of a larger Alamosa Land Institute...

Description of Work U.S. Geological Survey (USGS) will develop and provide forecasting tools for managers to determine how water withdrawals or other hydrologic or land use changes in watersheds may affect Great Lakes ecosystems. This information will help guide restoration efforts to achieve maximum effectiveness and success. Project provides unified information across the Great Lakes Basin for ecosystem restoration, assessment, and management by incorporating models that relate changes in landscape and hydrologic variables and stresses to changes in ecosystem function. The project relies upon regionally consistent hydrologic, biologic, and geospatial data to generate regionally consistent estimates, models, and...

The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for monitoring the overall condition of the watershed, and by combining stream and soil monitoring within watersheds, the response of Adirondack ecosystems to environmental disturbances such as acid rain and climate change can be better understood. For example, the unexpectedly slow reversal of stream acidification from decreased atmospheric...

Description of Work The Great Lakes ecosystem has undergone major changes over the last two decades related to the invasion of Dreissenid mussels, increased water clarity, increased benthic algae and associated water quality problems. For reasons not yet entirely understood, and that have bi-national significance, water column total phosphorus has not significantly increased over the last decade but the relative percent of the more biologically available dissolved phosphorus has increased. The filtering action of Dreissenid mussels has been shown to increase concentrations of dissolved phosphorus in the water column immediately above mussel beds and this had been hypothesized as one explanation for the increase...

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...

Description of Work This project is designed to (1) collect more frequent total suspended sediment (TSS) and total phosphorous (TP) data for the Genesee River Watershed, especially sub-watersheds at the 12-digit HUC (Hydrologic Unit code) scale, both within and outside of the AOC; and (2) to conduct a pilot study capable of evaluating the reduction in sediments and nutrients from the current and proposed GLRI non-point source reduction projects in the watershed aggregated at the 12-digit HUC. This project is envisioned as a two-year pilot for the Genesee River Watershed, with potentially wider applications in the Lake Ontario Basin and other Great Lake areas.
