Rapid growth in unconventional oil and gas (UOG) has produced jobs, revenue, and energy, but also concerns over spills and environmental risks. We assessed spill data from 2005 to 2014 at 31 481 UOG wells in Colorado, New Mexico, North Dakota, and Pennsylvania. We found 2-16% of wells reported a spill each year. Median spill volumes ranged from 0.5 m3 in Pennsylvania to 4.9 m3 in New Mexico; th...

~BSTRACT: A~ unsteady ~wo-dimens~onal (20) reservoir hydrodynamics and transport model is employed to slm~late contammate~ denSity cu~ents m the Shasta Reservoir after a chemical spill into the Sacramento River, Cahf. Three flow regimes (plungmg flow, underflow, and interflow) and their occurrence are captured by the laterally ~verag~d model. Transp~~ and mixing processes in the temperature-str...

Large-scale releases of environmental contaminants from industrial facilities can cause considerable damage to surrounding ecosystems and require remediation. The expense and/or undesirable environmental side effects of physical removal may constrain remediation efforts. In 2008, approximately 4.1 million m3 of fly ash were released into the Emory River at a coal-burning power plant in Kingston...

nowadays, agricultural r&d provides new and developed technologies to create modern agricultural producing methods. during recent years, improving agricultural productivity is affected by not only domestic r&d investments but also foreign countries r&d investments. nowadays, according to new growth models, r&d is the base of productivity. recent economic theories consider agricu...

A major fraction of the petroleum hydrocarbons discharged during the 2010 Macondo oil spill became associated with and sank to the seafloor as marine snow flocs. This sedimentation pulse induced the development of distinct bacterial communities. Between May 2010 and July 2011, full-length 16S rRNA gene clone libraries demonstrated bacterial community succession in oil-polluted sediment samples ...

This document lays out a framework by which defensible performance metrics for oil spill response can be developed in an analytic-deliberative process that includes a broad range of stakeholders and is informed by high quality scientific knowledge. Performance metrics can be used to: improve oil spill response planning, promote institutional learning post-response, support public communication ...

ABSTRACT Oil spill trajectory and fate modeling was used in inland response Full Scale Exercises including the Enbridge Des Plains River (fall 2018) Wisconsin 2019). The Spill Impact Model Application Package (SIMAP) to predict three-dimensional movement (i.e. trajectory) behavior fate) of a hypothetical release oil using site-specific environmental geographic conditions (including seasonal hyd...

Long-term monitoring of endangered species abundance based on acoustic recordings has not yet been pursued. This paper reports the first attempt to use multi-year passive acoustic data to study the impact of the Deepwater Horizon oil spill on the population of endangered sperm whales. Prior to the spill the Littoral Acoustic Demonstration Center (LADC) collected acoustic recordings near the spi...

Many satellite-borne image data have been acquired in the Arabian Gulf since the mid 80’s by different space agencies and have demonstrated oil spill related features at sea. Severe oil spills were caused occasionally by accidental or deliberate oil sludge dumping from passing ships. Serious damage to fishery, water desalination plants and natural habitats are concerned. The work done is the fi...
