These data include permafrost gas concentration data from the Alaska Peatland Experiment at various depths, times, and locations
The dataset contains site information such as latitude, pH, soil carbon, soil nitrogen, KEGG data from highly variable genes and cluster data.
Understanding the sources and quantities of greenhouse gas (GHG) emissions is critical to developing an emissions inventory that accurately represents various oil and gas industry segment operations. To address this, the American Petroleum Institute (API) formed a Greenhouse Gas Emissions Methodology Working Group. The working group’s objectives were to review, summarize and recommend methodologies for consistent estimation of GHG emissions from oil and gas industry facilities, including exploration and production through refining to product marketing. In a continued pursuit of consistent emission estimation methodologies for the oil and gas industry, the working group is meeting with other protocol development...
We evaluate the greenhouse gas footprint of natural gas obtained by highvolume hydraulic fracturing from shale formations, focusing on methane emissions. Natural gas is composed largely of methane, and 3.6% to 7.9% of the methane from shale-gas production escapes to the atmosphere in venting and leaks over the lifetime of a well. These methane emissions are at least 30% more than and perhaps more than twice as great as those from conventional gas. The higher emissions from shale gas occur at the time wells are hydraulically fractured—as methane escapes from flow-back return fluids—and during drill out following the fracturing. Methane is a powerful greenhouse gas, with a global warming potential that is far greater...
Drylands are considered a net sink for atmospheric methane and a main component of global inventories for greenhouse gas budgets. However, a significant portion of drylands occur over sedimentary basins hosting natural gas and oil reservoirs, with gas migration to the surface (named “microseepage”) producing positive atmospheric CH4 fluxes. In this overview, we summarize the outcomes of microseepage surveys performed in different petroleum basins, describe how the microseepage area is estimated and what are the emission factors that can be used for a preliminary global emission estimate. Microseepage frequently overcomes methanotrophic consumption occurring in dry soil throughout large areas, and it is enhanced...

Noise exposure is known to cause hearing loss and a variety of disturbances, such as annoyance, hypertension and loss of sleep. It is generally accepted that these situations are caused by the acoustical events processed by the auditory system. However, there are acoustical events that are not necessarily processed by the auditory system, but that nevertheless cause harm. Infrasound and low frequency noise (ILFN, <500Hz) are acoustical phenomena that can impact the human body causing irreversible organic damage to the organism, but that do not cause classical hearing impairment. Acoustical environments are normally composed of all types of acoustical events: those that are processed by the auditory system, and those...

This dataset consists of methane flux data collected with eddy covariance methods; and methane ebullition data collected with gas traps, time-lapse cameras, and capacitance probe measurements. Inferred bubble production and soil volumetric gas content data from capacitance probe measurements also are included. These data were collected from July to November 2016 at two forested wetlands in Big Cypress National Preserve, Florida. Gas trap, time-lapse camera, and capacitance probe data were collected at platforms located within the source area of each eddy covariance tower in forested wetlands. Each platform consisted of an array of gas traps, one time-lapse camera, and one capacitance probe. The location (geographic...

We analyzed tissue δ13C, δ15N, and δ34S of animals associated with hydrocarbon seeps on the lower continental slope of the Gulf of Mexico. We made discrete collections of fauna associated with four dominant chemosymbiotic seep fauna: vestimentiferan tubeworms, bathymodiolin mussels, vesicomyid clams, and Sclerolinum sp. (another siboglinid worm related to vestimentiferans). These collections were conducted in 2006 and 2007 using the manned submersible Alvin and the remotely operated vehicle Jason II, both operated by Woods Hole Oceanographic Institute. The purpose of this study was to use stable isotopes to explore potential nutritional sources and trophic interactions in these seep communities, especially those...
Why did nuclear energy policies in France, Sweden, and the United States, very similar at the time of the oil crisis of 1973 and 1974, diverge so greatly in the following years? In answering this question, James Jasper challenges one of the most popular trends in political analysis: explanations relying exclusively on political and economic structures to account for public policies. Jasper proposes a new cultural and state-centered approach--one heeding not only structural factors but cultural meanings, individual biographies, and elite discretion. Surveying the period from the successful commercialization of light-water-reactor technology in the early 1960s to the present, he explains the events that occurred after...
Coalbed methane is one of the most important and valuable natural resources in the Western United States. The natural gas that results from CBM development is the cleanest burning fossil fuel, and the extensive domestic supply makes it a central element of the national goal of a secure supply of energy. Demand for natural gas will continue to grow and CBM will play an increasingly larger role in meeting that demand. CBM production has expanded tremendously over the past decade, and the rapidity with which development has expanded has resulted in stresses and tension in affected communities. Development of this important energy resource must be balanced with a number of other important goals of protecting water,...

This dataset is field boundary polygons of Coalbed Methane (CBM) based on producing wells in the USA. Field outline polygons were created by buffering wells from each field. Buffered well polygons from each field were then unioned into a single polygon record (may contain multiple rings). A smoothing algorithm was applied to the polygons. Features are colored by Basin. Fields are coded with Geologic Ages, Formations, and Coal Names. Age Codes are Exxon Mobil Age Codes.

Recent research indicates that accumulation and release of biogenic gas from northern peatlands may substantially affect future climate. Sudden release of free-phase gas bubbles into the atmosphere may preclude the conversion of methane to carbon dioxide in the uppermost oxic layer of the peat, resulting in greater contribution of methane to the atmosphere than is currently estimated. The hydrology of these peatlands also affects and is affected by this process, especially when gas is released suddenly and episodically. Indirect hydrological evidence indicates that ebullitive gas releases are relatively frequent in some peatlands and time-averaged rates may be significantly greater than diffusive releases. Estimates...

This article provides a comprehensive and succinct review of the essentials needed to deal with the disputes encountered in the international energy sector. It begins with explaining the reasons why this sector has more disputes than any other business sector and then discusses how parties can effectively manage that risk. The article covers the kinds of disputes found in the international O&G business, the types of dispute resolution mechanisms available along with their respective advantages, and the legal framework for international arbitration. It explains how to properly draft dispute resolution clauses and what to consider in selecting counsel and in appointing arbitrators. A section is included that specifically...

Methane, nitrogen, oxygen, and carbon dioxide data were collected at two offshore submarine pockmarks, Miami Pockmark and Key Biscayne Pockmark. A series of dives were performed to gather the data using an autonomous underwater vehicle (AUV) with an Underwater Mass Spectrometer (UMS) instrument. The data were collected May 5-8, 2016 using a Bluefin B12 AUV equipped with a UMS and an onboard calibrated Kearfott T-24 Inertial Navigation System (INS) aided by a GPS Wide Area Augmentation System (WAAS), 600 kHz RDI Doppler Velocity Log (DVL) and a Valeport sound velocity meter. The methane, nitrogen, oxygen, and carbon dioxide data collected from Miami Pockmark and Key Biscayne Pockmark are displayed in figures 1-8.
