This document summarizes a study on the effects of navigational dams on the feeding morphology of two predatory fish species in the Ohio River. Measurements of mouth morphology, such as jaw length and gape width, were collected from specimens of freshwater drum (Aplodinotus grunniens) and bluegill (Lepomis macrochirus) caught from different pools. Principal component analysis found the freshwater drum from the glaciated valley pool had differing mouth morphology compared to those from alluvial valley pools, indicating differences in available prey. Jaw length was the most influential morphological measurement and varies between life stages and prey selection. Further research is needed to better understand differences in diet between populations.
The document discusses artificial reefs and Martin County's artificial reef program.

Carbon Sequestration: Potential of the Early Pennsylvanian Breathitt Group, P...rpgrimm
The document summarizes research on the potential for carbon sequestration in the Early Pennsylvanian Breathitt Group located in the central Appalachian Basin. The research aims to characterize reservoir properties and investigate storage capacities of shales and sandstones in the region. Core samples and outcrop measurements were analyzed alongside geophysical well log data to develop a sequence stratigraphy model identifying regional lithologies suitable for CO2 storage and sealing. The model found broad flooding surfaces and discontinuities indicating opportunities for targeted sequestration in the Pocahontas Basin. Further work will focus on the interplay of forces controlling basin development.
The document provides an overview of streams and stream restoration. It defines what a stream is and discusses fluvial geomorphology and forms. Key concepts covered include meandering streams, bankfull stage, stream ecosystems and functions. The effects of urbanization on streams and symptoms of "urban stream syndrome" are outlined. Factors that contribute to a healthy stream are identified, such as bed stability, sediment transport balance, in-stream habitat, bank stability, riparian buffers, active floodplains, and watershed health. Stream restoration planning and components involving channel morphology, floodplain structure, hydrologic analysis, in-stream structures, habitats and vegetation are summarized. Case studies of stream restoration projects are presented.
The Williams Fork Formation in the Piceance Basin of Colorado contains tight sandstone reservoirs that are an important source of natural gas. The reservoirs have low porosity and permeability but natural fractures enhance permeability. Gas is stored in thick, continuously gas-saturated sandstones and migrates through the extensive natural fracture network. These fractures formed due to overpressuring from coal seams and folding related to basement faults. Integrating seismic data, remote sensing, and modeling can effectively identify fracture-prone areas for gas production from these low-permeability reservoirs.
The document summarizes assessments of stream restoration and stormwater projects funded by the CWMTF. It discusses the types of restoration and stormwater projects funded, methods used to assess the projects, findings from site visits by field representatives, and presentations made on various project types including stream restoration, wetland restoration, agricultural BMPs, and stormwater BMPs. Key highlights include that most funded projects showed water quality benefits and compliance with goals, though some required maintenance and repairs, and presentations provided examples and findings on different best management practices.
This document discusses various components of stream restoration including:
1. In-stream structures like logs, rocks, and vanes that provide bank protection, habitat, and sediment transport.
2. Streambank stabilization techniques including temporary matting, root wads, and bioengineering with living plants.
3. Riparian buffers of grasses, wetland plants, shrubs, and trees along the stream banks.

The project aims to improve water quality in Accotink Creek and address drainage issues while enhancing the park environment.
This document summarizes findings from multiple watershed-scale studies on the effects of conservation practices conducted between 2004-2018 as part of the USDA CEAP program. Key findings include:
1) The implementation of conservation practices like cover crops, riparian buffers, and nutrient management plans effectively reduced nutrients and sediments in surface waters in several watersheds across the country.
2) Models were used to identify priority areas for conservation and predict load reductions, however watershed responses were complex and variations in practices and conditions made broad effects difficult to detect.
3) While edge-of-field water quality often improved with conservation practices, stream impacts were more dependent on factors like bank erosion and riparian conditions.
Reconstructing Water Levels in the Lake Michigan Basin from Embayed LakesSERC at Carleton College
This document discusses reconstructing past water levels in the Lake Michigan basin from sediment cores taken from embayed lakes. Lake level histories can be determined from geomorphic evidence like stranded shorelines and submerged forests, as well as sedimentological evidence like layers of sand, peat, marl, and gyttja in cores. Cores from small embayed lakes can preserve records of fluctuations in large lake levels over thousands of years. Comparing data from multiple sites allows development of a composite lake level curve for the region.
The document summarizes surveys of Deer Creek's floodplain and side channels conducted by University of Oregon students before implementation of a floodplain enhancement project. The surveys found a low amount of activated secondary channels and small/medium woody debris during spring. Future surveys after adding large woody debris to Deer Creek will assess whether the project improved water quality and salmonid habitat. The project aims to make Deer Creek's floodplain slower, colder, and more diverse to enhance habitat for Chinook salmon and bull trout.
This document summarizes research on classifying coral reef and seagrass habitats in the Pearl Cays region of Nicaragua using Landsat 8 satellite imagery. The objectives were to map these critical marine habitats and evaluate Landsat 8 for this application. The methodology involved preprocessing two Landsat 8 images, developing training sites, classifying the full scene and sectors using multiple classifiers, and comparing classifications to high resolution imagery. The results found that using image sectors provided more detailed coral classifications and reduced misclassification of sand as coral or seagrass. It was suggested that using multiple images and high resolution data could improve future classifications of these dynamic marine habitats.
The Babson Court Outfall Restoration Project in Fairfax County, VA restored a 324-foot outfall channel and 66-foot tributary to address erosion and public safety concerns. The restoration incorporated natural stream design techniques like step pools, rock steps, and riffles. It also removed 250 cubic yards of sediment from a dry pond, which was re-vegetated. The project is expected to reduce nitrogen, phosphorus, and suspended solid pollution in stormwater runoff.
The Lazy Creek Court Outfall Restoration Project in Fairfax County, Virginia restored 159 linear feet of an eroded outfall channel. The project addressed public safety concerns and stabilized the channel using natural stream design techniques like stone steps and plantings. This provides enhanced water quality through reduced nitrogen, phosphorus, and solid pollutants. The project was completed in August 2017 through collaboration between the Department of Public Works, a design firm, construction crews, and landscaping contractors.
1) The study modifies the geometry of the Fraser River in a numerical ocean model to improve simulations of tides and the Fraser River plume.
2) Extending and deepening the river channel generated stronger cross-strait surface currents that better matched observations, and tidal amplitudes in the estuary corresponded well with measurements.
3) Reducing vertical mixing parameters, such as eddy viscosity and diffusivity, produced weaker along-strait flow and surface current patterns closer to drifter data, further improving the model results.

Soil erosion is the removal of topsoil by various factors like water and wind. It is a natural process that has been accelerated 10-40 times by human activities like intensive agriculture, deforestation, roads, and climate change. This excessive erosion causes on-site issues like decreased productivity and off-site issues like sedimentation of waterways. The rate of erosion is affected by climate, soil properties, vegetation cover, and topography - with factors like heavy rainfall, lack of vegetation, and steep slopes increasing rates. Preventing erosion requires increasing vegetative cover through practices like terracing and windbreaks.
Climate change is happening as the Earth is warming due to increased greenhouse gas emissions. The average global temperature has risen 0.85°C from 1880 to 2012 and is projected to exceed 2°C by 2100. Small changes in average temperature can lead to large shifts in climate and weather. Evidence shows changes in rainfall patterns, more extreme weather events, rising sea levels, and impacts on ecosystems. The document then provides details on climate change impacts expected for India, such as changes in weather patterns, sea level rise, impacts on agriculture and food security. Case studies on projected climate trends and impacts in Bhubaneswar, India are also presented, along with proposed resilience actions.
This document discusses soil erosion, its causes, impacts, and methods for measuring and addressing it. It provides context on the development of the Universal Soil Loss Equation to quantitatively predict erosion. While useful, the USLE does not capture extreme weather events that cause most erosion. Direct measurements are most accurate but also most resource-intensive. The document outlines various on-site and off-site impacts of erosion and early efforts to address the problem through the Soil Conservation Service and projects like Coon Creek Watershed.
Soil erosion is caused by both natural processes like wind and water, as well as human activities such as deforestation, overgrazing, monoculture farming, and removing windbreaks. This accelerated erosion decreases soil fertility and crop production. Several methods can limit soil erosion, including terracing to hold soil and water, contour ploughing across slopes, planting shelter belts to protect soil, using strip farming to minimize bare soil, and installing stone lines along contours to reduce runoff.
Climate change poses serious threats to Indian agriculture that could undermine food security. Studies project cereal production may decrease 10-40% by 2100 due to increased temperatures, with wheat facing greater losses. Every 1°C rise in temperature could reduce wheat production by 4-5 million tons. Adaptation strategies like new crop varieties, water management, and insurance can help minimize impacts but require significant research and policy support. Immediate action is needed on low-cost adaptation options while determining costs and policies for long-term mitigation through practices like agroforestry and soil carbon sequestration. Failure to act risks substantial economic and social damages from climate impacts on India's agricultural sector and food system.
This document summarizes efforts to upgrade shellfish growing area classifications in local waters. Water quality and shellfish surveys identified potential geoduck and horse clam beds. Sediment and shellfish tissue samples found no human health risks from contaminants. Dye studies showed limited water circulation, informing recommendations to restrict harvesting near sewage sources. Upstream stewardship programs and the surveys together allowed areas to be reclassified, expanding sustainable shellfish harvesting opportunities.

Marine Invasives of Kachemak Bay, AlaskaKBay Council
This document discusses marine invasives of concern in Kachemak Bay, Alaska. It describes characteristics of successful invaders like green crabs and tunicates, which are able to establish due to a lack of natural predators and broad tolerances. Shipping ballast water is identified as the primary vector introducing over 80% of non-native species to North America. The document advocates for monitoring programs aimed at early detection of invaders, as well as regulatory actions like mid-ocean ballast exchange, as the most effective approaches for preventing and responding to marine invasives in Kachemak Bay.
Dams and barrages have environmental impacts while also providing benefits. Dams generate power, supply water, stabilize flows for irrigation, prevent floods, reclaim land, and create recreation areas. However, they can cause seepage, affect groundwater, trap sediments, and change river ecology. Reservoirs can introduce invasive species and changes in water quality impact fertility, pollution, diseases, and species extinction. Large dams have even caused the Earth's rotation to speed up. Barrages similarly control water flows but have impacts like increased turbidity, altered sediment movement, and breeding of mosquitoes.

This study characterized the microbial community structure of a dormant pockmark on the Malin Shelf off the coast of Ireland. Analysis showed distinct bacterial and archaeal populations compared to known high-activity methane seep sites. Psychrobacter and Sulfitobacter species dominated the bacterial communities and exhibited genetic divergence between sediment depths. Minor groups related to active seepage were also present, suggesting low ongoing methane seepage. The lack of known sulfate-reducing bacteria and dominance of heterotrophic proteobacteria feeding on organic matter suggests this dormant pockmark community is in a transitional stage following reduced fluid flow.
1. This document describes a study that developed a protocol using underwater videography to quantify trout populations. Video recordings were taken and analyzed from multiple cameras suspended in pools in Pauma Creek, part of the San Luis Rey River system in Southern California. This provided more accurate population data than other survey methods and was less detrimental to the imperiled fish populations.
2. The goal was to establish a lightweight camera system that could be easily deployed in remote areas to survey trout populations in less than an hour, as an alternative to electrofishing, netting, or snorkel surveys which can stress or harm the fish. The study focused on quantifying the native trout population in Pauma Creek, which historically contained coastal steelhead

It found that natural sites were accreting sediment at a rate that could keep pace with rising sea levels, while diked or drained sites showed evidence of subsidence. Restored sites had high carbon storage and accumulation rates, demonstrating the potential for tidal wetland restoration to enhance resilience to sea level rise through carbon sequestration and sediment accretion.
The current status of ASR Technology: Firming up Victoria's water supplyThe Texas Network, LLC
This document discusses the current status of Aquifer Storage and Recovery (ASR) technology. It provides an overview of ASR including its historical development and global implementation. Key points include that over 544 ASR wells exist across 133 wellfields in the US. The document discusses various water sources and aquifer types used for ASR storage. It also outlines several potential objectives for ASR systems, such as seasonal storage, emergency storage, and water quality improvement. Cost comparisons show ASR can be less expensive than other new water supply options. The remainder of the document discusses various ASR applications and case studies in more detail.
This document contains two chapters that summarize research on bowfin and northern sunfish populations. The first chapter describes a study of a bowfin population in Lake Ontario that found they grew slower than populations at lower latitudes. It also investigated captive breeding and found bowfin require induced breeding. The second chapter examines the status of the last wild northern sunfish population in a New York creek and changes in the fish community including hybridization with bluegill.

The document discusses the proposed Keystone XL pipeline that would transport crude oil from Canada through the U.S. to Texas. It notes concerns about the pipeline's proposed route through Nebraska's ecologically sensitive Sandhills region, which contains important wetlands and groundwater resources. While the pipeline may provide economic benefits, there are environmental risks like contamination from potential oil spills that could harm the Sandhills and Ogallala Aquifer. The document examines these issues and potential impacts through maps, photos from the Sandhills region, and discussions of previous pipeline oil spills.
The document summarizes the Urban Assembly New York Harbor School's oyster restoration and research project. It details the school's history with oyster restoration since 2003, including building floating upweller systems and reefs holding hundreds of thousands of oysters. It describes the school's remote setting process which resulted in over 2 million oysters, and its nursery and growout activities. It also outlines the design of constructed reefs, monitoring techniques, and diving protocols developed to safely deploy and monitor oysters in New York Harbor.

Summary
• Erosion along Homer shoreline an ongoing concern
• Salt marshes are sensitive to changes in elevation & sedimentation
• Glaciers are receding and thinning, at an accelerating rate
• To predict climate-change impacts, we need to understand:
• Balance between coastal uplift rates and sea-level rise
• Whether uplift rates are uniform; relation to underlying geology
• Changes in frequency, intensity, and direction of storm events
• Changes in glacial melt and sedimentation rates
• For salt marsh habitats, the importance of these habitats to a
wide range of species
