Marine seismic surveys and ocean noise: time for coordinated and prudent planning

Frontiers in Ecology and the Environment, 2015

Marine seismic surveys use intense (eg ≥ 230 decibel [dB] root mean square [RMS]) sound impulses ... more Marine seismic surveys use intense (eg ≥ 230 decibel [dB] root mean square [RMS]) sound impulses to explore the ocean bottom for hydrocarbon deposits, conduct geophysical research, and establish resource claims under the United Nations Convention on the Law of the Sea. The expansion of seismic surveys necessitates greater regional and international dialogue, partnerships, and planning to manage potential environmental risks. Data indicate several reasons for concern about the negative impacts of anthropogenic noise on numerous marine species, including habitat displacement, disruption of biologically important behaviors, masking of communication signals, chronic stress, and potential auditory damage. The sound impulses from seismic surveys – spanning temporal and spatial scales broader than those typically considered in environmental assessments – may have acute, cumulative, and chronic effects on marine organisms. Given the international and transboundary nature of noise from marin...

The present study examines the relationship of heat-related incidents in the City of Phoenix, Arizona from 2001 to 2006 relative to heat-climate variables, as well as relative to the socio-economic characteristics of the places where these incidents occurred. The 5th largest city in the United States, the City of Phoenix, with its building concentration and paved surfaces, has been subject to a worsening urban heat island (UHI) effect; this, coupled with the increasing severity of heat events due to climate change have served to compromise many residents' health condition. From a series of statistical and GIS analyses, we present here the population-level risk factors to heat events in the City of Phoenix, and show where these risk factors ar...

During this time of unprecedented growth, environmental engineers and scientists are faced with the additional complexities of global and regional climate change. This review paper focuses on the nexus of rapid urbanisation and summertime local climate change that can be addressed at the regional level—the built environment. First, it assesses the volumetric and physical characteristics that comprise the urban fabric of a region. Second, the paper presents a review of research efforts to date to quantify how surface material applications and microclimate are subject to the laws of thermodynamics, which can be altered in terms of engineered alternatives. This includes a review of surface mitigation research as presented in the context of sustainability.

Asphalt rubber asphalt concrete friction course overlay as a pavement preservation strategy

Characterization, Mechanisms, Simulation, and Modeling, 2008

In placing a thin layer, usually less than 1”, of Asphalt Rubber – Asphaltic Concrete Friction Course (AR-ACFC) over existing Portland Cement Concrete Pavement (PCCP), ADOT has reduced the noise impact to the surrounding neighborhoods from urban freeways by as much as 4 to 6 decibels. The use of specialized pavement mixtures to address a purely quality-of-life issue is dynamic and innovative, and the program has been remarkably well received by the taxpayers and users of the roadway network. However, one unintended consequence of the overlay program may be to significantly extend the life of the PCCP due to mitigation of daily thermal variances. By adding an additional, easily maintained layer, or “blanket”, over the PCCP, the underlying material will experience higher low temperatures and lower high temperatures. It is well known that temperature variations significantly lessen with depth, and the addition of even just a ¾” AR-ACFC layer may favorably affect the lower reaches. Thermally induced stresses to PCCP can be very damaging, and anything that would lessen the temperature swings would be very beneficial. Given the large investment in the PCCP infrastructure by ADOT for the Phoenix metropolitan freeway system, the dividends of extended pavement life and lowered maintenance costs could result in a substantial savings. This study included a field instrumentation effort with pavement temperature sensors to quantify the thermal behavior of the PCCP with and without the AR-ACFC overlays. Using established formulas for calculating the thermally induced curling stresses, the benefit to the overall pavement behavior is modeled, and the overlay strategy viewed as a pavement preservation tool is summarized.

Numerous government policies are now promoting sustainable management practices, while many people in the business and financial communities view sustainability as a means to reduce long-term risk, enhance competitiveness, and promote social well-being. Advances in science and technology are creating new economic opportunities and producing sustainable solutions, while expanded public access to global data and information is helping to shape business and government policies. Looking ahead, sustainability will be best pursued by building on these trends and encouraging new collaborative initiatives among governments, businesses, and the nonprofit sector. This article is an example of a collaboration that includes government, business, academic, nongovernmental, and international organizations.

Risk management consideration in the bioeconomy

Biofuels, Bioproducts and Biorefining, 2017

The biobased industry poses additional challenges as it competes in a mature, highly effi cient market, dominated by petroleum-based companies, and faces signifi cant feedstock availability and variability constraints, limited technological data, and uncertain market conditions for newly developed products. Thus, decision-making strategies and processes for these investment projects must consider solid risk estimation and mitigation measures. Focusing on the biobased industrial sector, this paper critically reviews state-of-the-art probabilistic and deterministic methodologies for assessing fi nancial risk; discusses how a complete risk analysis should be performed; and addresses risk management, listing major risks and possible mitigation strategies.

Institutional policies and incentives, and their role in driving the bioeconomy are also explored. In doing so, we present a detailed analysis of global agricultural and roundwood forestry production, including both intermediate and final uses. In addition to deciphering the internal flows of commodities within the bioeconomy, we present the spatial distribution of key industrial bioeconomy feedstock crops and their influence within the global economy, including flows in exportation and importation across ten geographical regions. Finally, along with the many advantages for industrial biofeedstocks, there are also environmental trade-offs. The results from this examination will equip researchers, industries, and governments with a superior ability to address the multi-dimensional feedbacks and synergies of the bioeconomy, as well as predict potential areas of risk and those that may prosper from future production increases.

The direct impact of UHI can be significant on both daytime and night-time temperatures, and the indirect impacts include increased air conditioning loads, deteriorated air and water quality, reduced pavement lifetimes, and exacerbated heat waves. Modifying the thermal properties and emissivity of roofs and paved surfaces and increasing the vegetated area within the city are potential mitigation strategies. A quantitative comparison of their efficacies and costs suggests that so-called cool roofs are likely the most cost-effective UHI mitigation strategy. However, additional research is needed on how to modify surface emissivities and dynamically control surface and material properties, as well as on the health and socioeconomic ...

This objective was achieved through two focus areas that outlined the scope of work of this research: thermal properties and reflectance evaluation, and heat absorption and transfer modeling. In the first focus area, the reflectance "albedo" characteristics of various concrete pavement surfaces / mix types were identified. Surface and in-depth pavement temperatures of several field sections were collected to help validate modeling efforts. Perhaps one of the most notable accomplishments in this focus area was the development of a simplified laboratory test procedure to measure the thermal conductivity of paving materials using cylindrical specimens. Laboratory tests were also conducted to measure key thermal properties of the different paving materials. These properties were used as input parameters for the pavement heat absorption and transfer model. In the second focus area, a pavement heat absorption and transfer model was developed and validated. This fundamental model accounts for the surface rates of solar radiation absorption and heat transmission of various pavements designs. It can be used for comparative evaluation for the different pavements designs in mitigating the Urban Heat Island Effect. The outcome of the two focus areas outlined above are envisioned to play a key role aiding future decision makers and designers when choosing appropriate pavement materials for their particular application. It will provide further awareness of urban heat island, and drives further municipal ordinances and building codes that incorporate environmentally appropriate materials into development and rehabilitation projects.
