Download or read book Lessons from the Taylor Energy Oil Spill History Seasonality and Nutrient Limitation written by Sarah Josephine Harrison and published by . This book was released on 2017 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2004, Hurricane Ivan destroyed Taylor Energy platform 23051 in the northern Gulf of Mexico. The site has leaked oil into the marine environment since the platform was destroyed, resulting in the nation's longest ongoing offshore oil spill. The Bureau of Ocean Energy Management has estimated that oil is leaking from the site at a rate of 1-55 barrels of oil per day, a range that far exceeds the average oil seep in the Gulf of Mexico and may exceed the sum of oil released from all 22,000 natural seeps in the Gulf (27 barrels per day). Despite $435 million in well intervention and containment efforts, oil is expected to leak for another century. This thesis explores the site in three installments. Chapter 1 provides a detailed site history and literature review of oil degradation in surface waters. Chapter 2 documents the history of this site through pooling publicly available records from the US Coast Guard, the US Geological Survey, and the National Oceanic and Atmospheric Administrations, revealing surprising seasonal oscillation of oil slick length and frequency at this site. Chapter 3 explores the biogeochemical implications of this seasonal variation with two transects of surface water, the first in October 2014, the second in June 2015. Chapter 4 features an amendment experiment to compare how hydrocarbon oxidation rates change upon adding inorganic nutrient and/or chemical dispersants. This initial study includes some of the first geochemical and biological measurements at the site and establishes surface waters of the Taylor Energy site as a seasonally dynamic environment with a robust and persistent hydrocarbon degrading microbial community.

Book excerpt: Environmental legislation is a relatively new concept in the United States' regulatory regime. High profile environmental disasters, including several in other countries, have underscored the challenges of effectively and efficiently responding to an environmental pollution event. For a thirty year period, beginning in the early 1960s, laws were enacted to address anthropogenic pollution and create response frameworks; some of the laws passed during the latter years pertained to oil pollution, specifically in response to high profile oil spills. The societal prevalence of oil and the recent expansion of marine oil production platforms into deeper waters have complicated the response efforts under the current legislative structure. The Gulf of Mexico's deep-sea drilling platforms and risk of hurricane damage increases the risk of industrial accidents leading to large scale oil spills. Although the Deepwater Horizon (DWH) oil spill in 2010 dominates recent discussion, consideration of a spill that began prior to the DWH, and continues into the present, illustrates a different set of issues. Persistent oil slicks have been observed less than 20 km offshore Louisiana within Mississippi Canyon lease block 20 (MC20), near the toppled Taylor Energy well jacket, which was destroyed by Hurricane Ivan's passage through the Gulf of Mexico in 2004. Immediately after the storm's final landfall, satellite images detected surface oil slicks at the site. Acoustic surveys observed prominent plumes of gas and oil rising from near the well jacket to the surface. The objective of this research was to evaluate these plumes and quantify the density and size frequency of bubbles. These findings provide a context to analyze the response efforts of the Unified Command (UC) and efficacy of the current environmental legislation. In the field effort, an oil and gas bubble collecting and imaging device (bubblometer) was constructed. Its components include a calibrated visualization chamber, transparent collection tube, and four sample cylinders. The bubblometer was mounted on the lower platform (skid) of a Comanche ROV. In its retracted position, the lower opening of chamber was closed; a hydraulic actuator extended the bubblometer beyond the skid so that the chamber was open at the bottom. Location of the plumes was determined by a NOAA acoustician, allowing the ROV operator to navigate to the site and position the bubblometer within the plumes. Video of bubbles passing through the bubblometer visualization chamber and entering the collection tube was recorded with an HD video camera calibrated to resolve 4 pixels/mm. Video frames were analyzed with a Matlab based machine learning algorithm to count, classify, and measure gas and oil bubbles to provide an estimate of oil flux at the MC20 site. A total of 12,139 bubbles were counted (5,881 gas and 6,258 oil) and were typically 5-10 mm or greater. Gas bubbles contained 35.6% oil by volume. These results contributed to the refutation of Taylor Energy's "rum punch" hypothesis that remnant oil in the sediments is the primary source of the surface slick and indicate that at least one well is actively leaking at the site. Contention within the UC protracted the response efforts and revealed weaknesses within the structure and the legislation under which it was created. Lessons learned from the Taylor Energy oil spill should lead to the modification of existing environmental legislation to address deep-sea and other unique site conditions encountered during marine oil spills.

This book was released on 2014-08-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.

This book was released on 2020-04-24 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether the result of an oil well blowout, vessel collision or grounding, leaking pipeline, or other incident at sea, each marine oil spill will present unique circumstances and challenges. The oil type and properties, location, time of year, duration of spill, water depth, environmental conditions, affected biomes, potential human community impact, and available resources may vary significantly. Also, each spill may be governed by policy guidelines, such as those set forth in the National Response Plan, Regional Response Plans, or Area Contingency Plans. To respond effectively to the specific conditions presented during an oil spill, spill responders have used a variety of response optionsâ€"including mechanical recovery of oil using skimmers and booms, in situ burning of oil, monitored natural attenuation of oil, and dispersion of oil by chemical dispersants. Because each response method has advantages and disadvantages, it is important to understand specific scenarios where a net benefit may be achieved by using a particular tool or combination of tools. This report builds on two previous National Research Council reports on dispersant use to provide a current understanding of the state of science and to inform future marine oil spill response operations. The response to the 2010 Deepwater Horizon spill included an unprecedented use of dispersants via both surface application and subsea injection. The magnitude of the spill stimulated interest and funding for research on oil spill response, and dispersant use in particular. This study assesses the effects and efficacy of dispersants as an oil spill response tool and evaluates trade-offs associated with dispersant use.

Download or read book Biochar for Environmental Management written by Johannes Lehmann and published by Routledge. This book was released on 2012-05-16 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: Many of the pollutants discharged into the sea are directly or indirectly the result of human activities. Some of these substances are biodegradable, while others are not. This study is devoted to monitoring areas of the environment. Methods assessment is based on monitoring data and an evaluation of the impact of pollution.Surveillance provides a scientific basis for standards development and application. The methodology of marine pollution control is governed by algorithms and models. A monitoring strategy should be put in place, coupled with an environmental assessment concept, through targeted research activities in areas identified at local and regional levels. This concept will make it possible to diagnose the state of "health" of these zones and consequently to correct any anomalies. Monitoring of the marine and coastal environment is based on recent methods and validated after experiments in the field of marine pollution.
