The generation of electricity modifies the physical environment of the globe more than any other industrial activity. Indeed, the industry may already create more long-term economic costs than benefits in terms of associated environmental repercussions. This negative economic equation could become even worse unless long-term and programmed investments into energy supply and conservation strategies are made with proper care for all indentifiable environmental effects. The present publiclyowned electricity industry in the UK has an environmental track record that is patchy but generally unsatisfactory, despite some improvements in recent years. The key issue facing the privatized industry is how comprehensive and...
Description of Work Since 2010, connecting channels have been included in each of the Great Lakes’ Lake Management Plans (LaMPs). Lake Ontario now includes both the Niagara River and the St. Lawrence River. The Niagara River is well characterized by a number of long-term programs, but because of the lack of tributary water-quality data, the St. Lawrence River and its tributaries constitute a data gap in the information needed for the Lake Ontario to fulfill its goals. Critical information needs, including basic water-quality parameters, total suspended solids, nutrients and flow data. These data are needed to aid in the identification of sources of nutrient and sediment loading to the St. Lawrence. The monitoring...

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...

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.

These files were used to construct corridors estimating the extent of new coastal corridors exposed by reduced lake levels. They are included here to show the available horizontal extent of lidar-derived topo-bathymetric data and thus explicitly identify gaps and limitations of predicted corridor extents under various reduced lake level scenarios. In addition, these files provide users with a background layer that depicts the topographic variability of the submerged near-shore lake bed and terrestrial landscape.These files are 5m grid representations of the hydrographic and topographic data collected by the CHARTS system along the coasts of the U.S. sides of Lake Michigan, Lake Huron, Lake St. Clair, Lake Erie,...

Description of Work USGS scientists will support EPA's year of intensive sampling around the Great Lakes to complement and expand upon EPA and other partner entities work. In 2013, on Lake Ontario USGS will sample the food web from a nearshore (20 m) to offshore (100 m) gradient where seasonal sampling of primary producers, benthic invertebrates, zooplankton, prey fish, sport fish, and their diets will occur. We will work closely with state management agencies and stakeholder groups to ensure that ecosystem models that emerge from this work explore relevant future management scenarios. Scientists will analyze the diets of the six species of trout and salmon currently occurring in Lake Ontario. This predator diet...

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 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 U.S. Geological Survey (USGS) will expand the online availability of geospatial data to monitor the presence and extent of invasive species in wetlands, coastal areas and other sensitive habitats. USGS is working with the Great Lakes Observing System collaboration and other data sharing efforts across the Great Lakes to compile the data into a user friendly format that is accessible on line. Elevation data will be expanded in the Great Lakes Basin using a collaborative to support the GLRI. This information would support invasive species monitoring, wetland inventory, and habitat restoration. USGS will work with the Great Lakes Observing System and other data sharing efforts to make USGS geospatial...
This paper describes an approach to determine the relative accountability that each region and individual nation should bear in reducing atmospheric greenhouse gas. The paper argues that accountability should be based on equity and that all measures of equity for which there are backers should be used in the decision making procedure. Each equity indicator defines a different accountability profile, leading to conflicting prescriptions. Multicriterion decision making methods are seen as having high potential to help design fair compromise profiles, and a methodology is proposed and numerous methods indicated for this purpose. The methodology is illustrated by defining ! 1 different equity indicators and then formulating...
