EARTH’S CLIMATE CHANGES. It always has and always will. However, an extensive and growing body of scientific evidence indicates that human activities—including the burning of fossil fuel (coal, oil, and natural gas) for energy, clearing of forested lands for agriculture, and raising livestock—are now the primary force driving change in the Earth’s climate system. This report describes how the climate of northern New Hampshire has changed over the past century and how the future climate of the region will be affected by a warmer planet due to human activities.
Pose Detection And Control Of Multiple Unmanned Underwater Vehicles Using Optical Feedback, 2014 University of New Hampshire, Durham
Pose Detection And Control Of Multiple Unmanned Underwater Vehicles Using Optical Feedback, Firat Eren, Shachak Pe'eri, Yuri Rzhanov, May-Win Thein, Barbaros Celikkol
Center for Coastal and Ocean Mapping
This paper proposes pose detection and control algorithms in order to control the relative pose between two Unmanned Underwater Vehicles (UUVs) using optical feedback. The leader UUV is configured to have a light source at its crest which acts as a guiding beacon for the follower UUV which has a detector array at its bow. Pose detection algorithms are developed based on a classifier, such as the Spectral Angle Mapper (SAM), and chosen image parameters. An archive look-up table is constructed for varying combinations of 5-degree-of-freedom (DOF) motion (i.e., translation along all three coordinate axes as well as pitch and …
Effects Of Urban Stream Burial On Organic Matter Dynamics And Reach Scale Nitrate Retention, 2014 US Environmental Protection Agency
Effects Of Urban Stream Burial On Organic Matter Dynamics And Reach Scale Nitrate Retention, Jake J. Beaulieu, Paul M. Mayer, Sujay S. Kaushal, Michael J. Pennino, Clay P. Arango, David A. Balz, Timothy J. Canfield, Colleen M. Elonen, Ken M. Fritz, Brian H. Hill, Hodon Ryu, Jorge W. Santo Domingo

Nitrogen (N) retention in streams is an important ecosystem service that may be affected by the widespread burial of streams in stormwater pipes in urban watersheds. We predicted that stream burial suppresses the capacity of streams to retain nitrate (NO3 −) by eliminating primary production, reducing respiration rates and organic matter availability, and increasing specific discharge. We tested these predictions by measuring whole-stream NO3 − removal rates using 15NO3 − isotope tracer releases in paired buried and open reaches in three streams in Cincinnati, Ohio (USA) during four seasons. Nitrate uptake lengths were 29 times …

Center for Lakes and Reservoirs Publications and Presentations
In order to educate a broad cross section of the public about Aquatic Invasive Species (AIS) distributions and survey efforts in Oregon’s lakes and reservoirs, database connections were created to display AIS information on the Online Atlas of Oregon Lakes (aol.research.pdx.edu/). The connections allowed for the dynamic display of AIS survey records stored in three separate databases: the Center for Lakes and Reservoir’s Oregon Aquatic Plant and Mussel Databases and the iMapInvasives database. AIS survey records collected by the Center for Lakes and Reservoirs were also reported to the iMapInvasives database.
Issue Brief: Asset Management For Stormwater, 2014 University of Southern Maine
Issue Brief: Asset Management For Stormwater, New England Environmental Finance Center, Sustainable Communities Learning Network
Sustainable Communities Capacity Building
Asset management is a strategic approach to maintaining and sustaining infrastructure in order to meet the needs of the community at the lowest overall life cycle cost. This approach helps communities know how and where to prioritize limited funds in order to achieve the greatest benefit. Often applied to drinking water and wastewater infrastructure, this method is well suited to managing any assets, including stormwater systems.
This issue brief is intended to introduce local governments to the asset management process and to show how it can be applied in managing stormwater assets. It was adapted from an appendix written by …

Historical Reconstruction Of Population Density Of The Echinoid Diadema Antillarum On Florida Keys Shallow Bank-Barrier Reefs, Donald L. Kissling, William F. Precht, Steven Miller, Mark Chiappone
Marine & Environmental Sciences Faculty Articles
The 1983–1984 caribbean-wide mass mortality of the once ubiquitous long-spined sea urchin Diadema antillarum Philippi, 1845, is one of several factors considered responsible for coral reef change throughout the region. Unfortunately, there is a paucity of pre-mortality event density data for D. antillarum in the Florida Keys, making it difficult to determine pre-1983 population density levels. results from surveys conducted during 1970–1973 in the lower Florida Keys, in shallow (<12 m) fore reef habitats, yielded relatively abundant and widespread D. antillarum densities in qualitative transects at five reefs prior to the 1983–1984 die-off. In quantitative surveys at one reef, Middle sambo reef in 1972, up to 7.9 individuals m …12>

Uncertainties In Life Cycle Greenhouse Gas Emissions From U.S. Beef Cattle, 2014 University of Nebraska-Lincoln
Uncertainties In Life Cycle Greenhouse Gas Emissions From U.S. Beef Cattle, Quentin M. Dudley, Adam Liska, Andrea K. Watson, Galen E. Erickson
Adam Liska Papers
Beef cattle feedlots are estimated to contribute 26% of U.S. agricultural greenhouse gas (GHG) emissions, and future climate change policy could target reducing these emissions. Life cycle assessment (LCA) of GHG emissions from U.S. grain-fed beef cattle was conducted based on industry statistics and previous studies to identify the main sources of uncertainty in these estimations. Uncertainty associated with GHG emissions from indirect land use change, pasture soil emissions (e.g. soil carbon sequestration), enteric fermentation from cattle on pasture, and methane emissions from feedlot manure, respectively, contributed the most variability to life cycle GHG emissions from beef production. Feeding of …

An OLW website was developed to educate about AIS and provide survey protocols and identification materials to volunteers. AIS surveys …
Wind Pattern Effects On The Southern Shetland Islands, 2014 University of Southern Maine
Wind Pattern Effects On The Southern Shetland Islands, Helen Pottle
Thinking Matters Symposium Archive
The Shetland Islands, northeast of Scotland, experienced an unusually extreme storm that caused unique sand shifting patterns and sand dune formations that resulted in the destruction of the Village of Broo. There is little existing information about the weather and terrain of the Shetland Islands during the extreme storm that was estimated to have occurred between 1650 and 1670. WindNinja, a wind model originally developed for wildland fire application, was used to understand the wind patterns that may have caused the unique sand patterns and resulting destruction. It incorporates existing terrain elevations and vegetation as well as average wind speed …
Cosmogenic Beryllium Cycling In A Natural Forest Setting, 2014 Purdue University
Cosmogenic Beryllium Cycling In A Natural Forest Setting, Grace Conyers
Open Access Theses
10 Bemet , or cosmogenic beryllium, has a long half-life of 1.4 million years and quick adsorption on soil particles, which may make it ideal for dating soil erosion in historical context. However, there are questions on about the fundamental assumptions of the retentivity of 10 Bemet . This manuscript explores these assumptions and the context of nutrient cycling in a natural forest setting.
To see if 10 Bemet was being cycled through the trees, and at what rate, we looked at the[10 Bemet ] in the soil, 4 species of trees, and their leaves. The isotopic ratio 10 Be/9 …
Investigation Of Isotope Effects Of Ozone As A Function Of Temperature, 2014 Purdue University
Investigation Of Isotope Effects Of Ozone As A Function Of Temperature, Daniel J. Mcmahon
Open Access Theses
Ozone is an important oxidizer in the atmosphere and plays a crucial role as a cleanser, removing various compounds such NOx and SOx. It also is intriguing to those that study stable isotopes as it has a unique signature found in no other oxygen containing molecule. Ozone is observed to fractionate mass independently, which means it does not follow the typical δ 17 O /δ18 O = 0.52 ratio expected for molecules enriched with 17 O and 18 O. The magnitude of ozone's mass independent enrichment has been studied in laboratory experiments and atmospheric observations but its explanation is still …
