David G. Terkla

The Massachusetts Ocean Partnership (MOP) Planning Frameworks Team, in consultation with the Massachusetts Executive Office of Energy and Environmental Affairs (EEA), and based on collective experience and a review of ocean, coastal and resource management programs from the US and other countries, suggests that nine elements are essential components of the framework for the Massachusetts Ocean Plan and its implementation. While management plans and programs generally have these elements in common, there are a range of options for carrying out each program component. These options were presented to structure and inform the development of the Massachusetts Ocean Plan. For the …

2010 Massachusetts Recreational Boater Survey: Final Report Submitted To The Massachusetts Ocean Partnership, Dan Hellin, Jack Wiggin, Kristin Uiterwyk, Kim Starbuck, Nicholas Napoli, David Terkla, Chris Watson, Anthony Roman, Leona Roach, Tim Welch

David G. Terkla

The Massachusetts Ocean Management Plan (Plan) completed in 2009 recognized recreational boating as an activity with “significant actual and prospective conflicts among multiple waterway uses in Massachusetts” and included the economic value of recreational boating as a key socio-economic indicator that will be used to inform coastal management. At the time of Plan completion, statistically robust recreational boating data were identified as an important need for comprehensive ocean planning. To fill this data gap, the 2010 Massachusetts Recreational Boater Survey gathered information on boating activity in Massachusetts’ coastal and ocean waters directly from recreational boaters. Researchers sent 10,000 surveys to …

Christopher N. Roman

In the summer of 2011, the Exploration Vessel NAUTILUS is undertaking a four-month expedition to the Black, Aegean and Mediterranean Seas, and North Atlantic Ocean. The primary goal of the NAUTILUS is to create a focus of international leadership for the development and integration of leading-edge technologies, educational programs, field operations, and public outreach programs for ocean exploration, in partnership with NOAA, National Geographic Society, Office of Naval Research, and other sponsors. To do so, the program uses a complement of deep submergence vehicle systems and “telepresence” technologies to engage scientists, educators and the public, both at sea and ashore, …

High Resolution Sea Floor Bathymetry Using High Frequency Multibeam Sonar And Structured Light Laser Imaging, C. Roman, G. Inglis, C. Smart, I. Vaughn, S. Carey

Christopher N. Roman

Detailed bathymetric maps of the sea floor with centimeter level resolution can be produced by underwater vehicles using multibeam sonars and structured light laser imaging. Over spatial scales up to tens of thousands of square meters it is possible to produce maps gridded to sub centimeter levels. This level of accuracy demands detailed treatments of the sensor relative data, the vehicle navigation data and the vehicle to sensor position and rotational offsets. The presented results will show comparisons between these two sensor modalities. Data have a been collected during recent field programs to the Kolumbo volcanic crater and the Southern …

Remote Analysis Of Grain Size Characteristic In Submarine Pyroclastic Deposits From Kolumbo Volcano, Greece, C. Smart, D. P. Whitesell, C. Roman, S. Carey

Christopher N. Roman

Grain size characteristics of pyroclastic deposits provide valuable information about source eruption energetics and depositional processes. Maximum size and sorting are often used to discriminate between fallout and sediment gravity flow processes during explosive eruptions. In the submarine environment the collection of such data in thick pyroclastic sequences is extremely challenging and potentially time consuming. A method has been developed to extract grain size information from stereo images collected by a remotely operated vehicle (ROV). In the summer of 2010 the ROV Hercules collected a suite of stereo images from a thick pumice sequence in the caldera walls of Kolumbo …

Detection Of Diffuse Sea Floor Venting Using Structured Light Imaging, G. Inglis, C. Smart, C. Roman, S. Carey

Christopher N. Roman

Efficiently identifying and localizing diffuse sea floor venting at hydrothermal and cold seep sites is often difficult. Actively venting fluids are usually identified by a temperature induced optical shimmering seen during direct visual inspections or in video data collected by vehicles working close to the sea floor. Relying on such direct methods complicates establishing spatial relations between areas within a survey covering a broad area. Our recent work with a structured light laser system has shown that venting can also be detected in the image data in an automated fashion. A structured light laser system consists of a camera and …

The Effects Of Evapotranspiration Upon Recharge Using The Stable Isotopes Of Oxygen And Hydrogen In The Carbonate Aquifers Of The Cumberland Plateau In Southeast Kentucky, Lee J. Florea

Lee J Florea, PhD, P.G.

In this brief manuscript, we consider the variation of the stable isotopes of oxygen, δ18O, and hydrogen, δ2H, in samples collected during 2010 and 2011 from precipitation and shallow groundwater along the Cumberland Plateau of southeast Kentucky. These data from the 1,900-ha Redmond Creek karst aquifer lend insight into the source and timing of recharge to shallow groundwater in the epigenic karst of the U.S midcontinent. Specifically, we find that only 43% of precipitation remains as potential recharge after accounting for evapotranspiration, and 85% of this potential recharge occurs during only four two-week sampling periods. The isotopic composition of precipitation …

Radon As An Indicator Of Limited Cross-Shelf Mixing Of Submarine Groundwater Discharge Along An Open Ocean Beach In The South Atlantic Bight During Observed Hypoxia, Clayton Mccoy, Richard Viso, Richard Peterson, Susan Libes, Brent Lewis, John Ledoux, George Voulgaris, Erik Smith, Denise Sanger

George Voulgaris

Amongst other ocean state parameters, the development of a wave measurement program was supported as part of the Southeast U.S. Atlantic Coastal Ocean Observing System (SEACOOS). The program focused on supporting nearshore wave measurements using both cabled and autonomous systems but also examined the feasibility of using HF Radar systems for remote estimation of wave parameters. The nearshore stations have provided a significant database on directional wave climate for a number of nearshore locations in the region that provide valuable information to coastal engineers and managers for sustainable development along the coast of the southeastern United States. The ability of …

Mesosphereic Temperature Variability And Seasonal Characteristics Over The Andes, Jonathan R. Pugmire, Yucheng Zhao, Michael J. Taylor, Dominique Pautet

Jonathan Pugmire

The Utah State University CEDAR Mesospheric Temperature Mapper (MTM) is a high-quality CCD imager capable of remote sensing faint optical emissions from the night sky to determine mesospheric temperature and its variability at an altitude of ~87 km. The MTM was operated at the new Andes Lidar Observatory (ALO)located at Cerro Pachon, Chile (30.2° S, 70.7° W) since August 2009 to investigate the seasonal characteristic of the mesopause at mid-latitudes. Measurement were made alongside a powerful lidar capable of height sounding the mesosphere. In this study, the MTM data have been analyzed to determine night to night variability and seasonal …

Federal Energy Efficiency And Conservation Laws, John Dernbach, Marianne Tyrrell

John C. Dernbach

This paper provides an overview of U.S. law and policy concerning energy efficiency and conservation. The United States appears torn between two narratives - one expressing the abundant demonstrated opportunities provided by energy savings and the other based on a fear of deprivation from using less energy. Rather than choosing between the two, U.S. law and policy splits the difference - embracing efficiency and conservation more or less halfheartedly. Energy efficiency and conservation policy thus has a Groundhog Day aspect, in which the same or similar arguments are made year after year, decade after decade, and often (it appears) to …

Development Of High Resolution Sea Floor Mapping Tools And Techniques, Gabrielle Inglis, Ian Vaughn, Clara Smart, Chris Roman

Christopher N. Roman

There is a persistent need for high resolution photographic and bathymetric maps of the sea floor for many research areas in marine geology, biology and archaeology. This poster will present recent work using high frequency multibeam sonars, stereo vision and structured light laser imaging techniques to create maps with centimeter resolution for these applications. This research involves the development of new image and sonar processing techniques that combat the typical difficulties of imperfect navigation information, limited sensor ranges and adverse environmental conditions associated with using marine robotic vehicles in the ocean. Data for this work has been collected with the …

Next Generation Recycling & Waste Reduction: Building On The Success Of Pennsylvania’S 1988 Legislation, John C. Dernbach

John C. Dernbach

The Municipal Waste Planning, Recycling, and Waste Reduction Act (Act 101 of 1988) keeps millions of tons of materials out of landfills every year. It supports a multi-billion dollar industry that provides tens of thousands of jobs. It also probably affects human environmental behavior more than any other statute in state history. And it reduces greenhouse gas emissions at the same time because of the materials and energy that are saved.

Yet the program is now rudderless and drifting. While the Act contains specific goals, those goals have either been met or ignored, and no new goals have been set. …

Sensitivity Analysis Of Empirical Parameters In The Ionosphere-Plasmasphere Model, Janelle V. Jenniges

Janelle V Jenniges

A sensitivity analysis of empirical parameters used in physics-based models was completed in this study to determine their effect on electron densities and total electron content (TEC) in the ionosphere. The model used was the Ionosphere- Plasmasphere Model (IPM) developed by Utah State University. The empirical pa- rameters studied include the O+/O collision frequency, zonal wind, secondary electron production, nighttime E⃗ × B⃗ drifts, and tidal structure. The sensitivity analysis was completed by comparing a default run of the IPM to a run with the parameter ad- justed for three geophysical cases. Many of the comparisons resulted in nonlinear changes …

The Essential And Growing Role Of Legal Education In Achieving Sustainability, John Dernbach

John C. Dernbach

This article suggests that law schools need to play a leading role in the national and global effort to achieve sustainability, including the effort to address climate change. The article first describes the various drivers for sustainability in law schools. Clients are increasingly demanding that their lawyers 'walk the talk,' as many businesses and corporations already are. The universities that provide an institutional home for most law schools are also adopting sustainability policies and practices that influence their law schools. Within the legal profession, the American Bar Association, as well as many state and local bar associations, have adopted a …

Wind-Speed Inversion From Hf Radar First-Order Backscatter Signal, W Shen, Klaus-Werner Gurgel, George Voulgaris, Thomas Schlick, D Stammer

George Voulgaris

Land-based high-frequency (HF) radars have the unique capability of continuously monitoring ocean surface environments at ranges up to 200 km off the coast. They provide reliable data on ocean surface currents and under slightly stricter conditions can also give information on ocean waves. Although extraction of wind direction is possible, estimation of wind speed poses a challenge. Existing methods estimate wind speed indirectly from the radar derived ocean wave spectrum, which is estimated from the secondorder sidebands of the radar Doppler spectrum. The latter is extracted at shorter ranges compared with the first-order signal, thus limiting the method to short …

Implementation And Modification Of A Three-Dimensional Radiation Stress Formulation For Surf Zone And Rip-Current Applications, Nirnimesh Kumar, George Voulgaris, John Warner

George Voulgaris

Regional Ocean Modeling System (ROMS v 3.0), a three-dimensional numerical ocean model, was previously enhanced for shallow water applications by including wave-induced radiation stress forcing provided through coupling to wave propagation models (SWAN, REF/DIF). This enhancement made it suitable for surf zone applications as demonstrated using examples of obliquely incident waves on a planar beach and rip current formation in longshore bar trough morphology (Haas and Warner, 2009). In this contribution, we present an update to the coupled model which implements a wave roller model and also a modified method of the radiation stress term based on Mellor (2008, 2011a,b,in …

Creating The Law Of Environmentally Sustainable Economic Development, John Dernbach

John C. Dernbach

This article argues that a key to sustainability is redirecting the law of economic development. From a historical perspective, sustainable development is an effort to integrate environmental protection and restoration with development. As a result, it is not possible to fully understand sustainable development unless we understand what development means. While that term is reasonably well understood at the international level, our closest analogue in the United States is not development in general but rather economic development. A great many recently enacted laws that move the United States toward sustainability can be understood as economic development laws. By understanding these …

The "Cash For Clunkers" Program: A Sustainability Evaluation, Marianne Tyrrell, John Dernbach

John C. Dernbach

This article describes and evaluates the effectiveness of the Consumer Assistance to Recycle and Save Act of 2009, also known as the “Cash for Clunkers” legislation. Under this law, Congress authorized persons trading in older and less fuel-efficient motor vehicles for newer and more fuel-efficient vehicles to receive a voucher worth up to $4,500 toward the purchase of the new vehicle. The article reviews various studies assessing the effectiveness of this legislation based on economic, social, and environmental criteria. Because these criteria are consistent with the goals of sustainable development, the legislation provides important lessons for future efforts to achieve …

Environmental Laws And Sustainability: An Introduction, John Dernbach, Joel Mintz

John C. Dernbach

In this introduction to the special issue of Sustainability on environmental laws and sustainability, we attempt to synthesize key lessons from the issue’s ten substantive articles. These lessons involve the use of law to achieve integrated decision-making, the use of pre-existing laws to foster sustainability, the centrality of sub-national governments in achieving sustainability, the background law of unsustainable development, the growing importance of climate change, the need to use law to protect and restore ecological integrity, the importance of judicial review and nongovernmental organizations, the need to translate sustainability into specific legal principles, the challenge of creating an appropriate national …

Energy Efficiency And Conservation: New Legal Tools And Opportunities, John Dernbach, Robert Mckinstry, Darin Lowder

John C. Dernbach

Many new and ambitious energy efficiency and conservation laws are being enacted at all levels of government—and with greater financial incentives than provided previously. These innovations are intended to overcome or minimize market barriers such as principal-agent problems, information and transaction costs, high internal discount rates, and up-front capital needs that discourage cost-saving investments. Innovations such as public-private partnerships also require significant legal input and creativity for the client to reap the often remarkably large energy and cost savings. This article reviews a range of these tools, especially financial legal mechanisms, that could help significantly reduce U.S. energy consumption.

In Situ Checks Of Sonic Anemometer Temperature Calibration, David Cook, Michael Negale

Michael Negale

The temperature calibration of the Gill Instruments WindMasterPro sonic anemometer used in the SGP ACRF ECOR systems is a curve, but is approximated as a linear fit for field use. The linear fit is only applied to the calculation of sensible heat flux and not to the reported temperature, and results in an underestimate of sensible heat flux during cold ambient temperatures and an overestimate during hot ambient temperatures. In situ calibrations performed using five years of ARM SGP ACRF data reveal how poorly the temperature is measured by the ECOR using the linear fit. Linear and non-linear in situ …
