From:Science (Vol. 254, Issue 5029) Peer-ReviewedTHE OCEAN BASINS CONTAIN A NUMber of large basaltic plateaus whose origins are uncertain. Some of the largest of these plateaus may have been erupted rapidly (<5 to 10 million years); if so, they may be the oceanic...

From:Ground Water (Vol. 33, Issue 4) Peer-ReviewedA study was conducted on buoyancy-induced flow during simulated two-well tracer tests in a homogeneous and isotropic sand pack. Two-well tracer tests were undertaken using Br- at concentrations ranging from 50-1,000...

From:Science (Vol. 280, Issue 5366) Peer-ReviewedMid-ocean ridges are undersea boundaries between Earth's crustal plates where new crust is formed. During crust formation, upwelling magma cools from temperatures of about 1200 [degrees] C to ambient values, releasing...

From:Ground Water (Vol. 39, Issue 6) Peer-ReviewedA recent paper by Hutchins and Acree (2000) has called attention to ground water sampling bias due to ambient (natural gradient-induced) flows in monitoring wells. Data collected with borehole flowmeters have shown that...

From:Atmospheric Measurement Techniques (Vol. 12, Issue 1) Peer-Reviewed
Absorption aerosol optical depth (AAOD) as obtained from sun-sky photometer measurements provides a measure of the light-absorbing properties of the columnar aerosol loading. However, it is not an unambiguous...

From:Atmospheric Chemistry and Physics (Vol. 17, Issue 20) Peer-ReviewedDinitrogen pentoxide (N.sub.2 O.sub.5) and nitryl chloride (ClNO.sub.2) are key species in nocturnal tropospheric chemistry and have significant effects on particulate nitrate formation and the...

From:Journal of the Air & Waste Management Association (Vol. 58, Issue 8) Peer-ReviewedABSTRACT This paper describes and theoretically evaluates a recently developed method that provides a unique methodology for mapping gaseous emissions from non-point pollutant sources. The horizontal radial plume...

From:Ground Water (Vol. 33, Issue 6) Peer-ReviewedBenzene, toluene, ethylbenzene and xylenes (BTEX) concentration ratios can be used to differentiate groundwater contaminant plume and determine its source. BTEX signatures are highly dependent on source properties rather...

From:Journal of Fire Sciences (Vol. 25, Issue 2) Peer-ReviewedABSTRACT: Since the physics of air entrainment is not yet clearly understood, most of the fire plume expressions reported in the literature were derived empirically. Experiments with different fire geometry, fuels, and...

From:Indoor and Built Environment (Vol. 16, Issue 4) Peer-ReviewedKey Words Natural ventilation E Large enclosure E Thermal stratification E Mathematical model There is a need for a good analytical model of natural ventilation of large enclosures. This study describes a...

From:Nature (Vol. 467, Issue 7311) Peer-ReviewedNow you see it, now you don't. According to news reports last week, the plume of oil in the depths of the Gulf of Mexico is no more. But just days earlier, the subsurface plume had been proclaimed a long-lived menace....

From:Ocean Science (Vol. 12, Issue 2) Peer-ReviewedSatellite remote sensing imagery and numerical modelling were used for the study of river bulge evolution and dynamics in a non-tidal sea, the Gulf of Riga (GoR) in the Baltic Sea. Total suspended matter (TSM) images...

From:Science (Vol. 280, Issue 5366) Peer-ReviewedThe migration and evolution of a deep ocean hydrothermal event plume were tracked with a neutrally buoyant RAFOS float. The float remained entrained in the plume for 60 days, and the plume vorticity was calculated...
-
From:Journal of Fire Protection Engineering (Vol. 16, Issue 3) Peer-ReviewedABSTRACT: This article examines various uncertainties relating to calculation methods for the balcony spill plume. The approach of physical scale modeling is used in the analysis. Comparisons are made between...

From:Science (Vol. 284, Issue 5417) Peer-ReviewedOn Earth, what goes up must come down. But inside the planet, just how things work hasn't been so obvious. Researchers probing Earth's interior have traced great sheets of rock--former sea floor--plunging deep into...
-
From:AORN Journal (Vol. 86, Issue 6) Peer-ReviewedELECTROSURGERY, LASER ABLATION, and ultrasonic scalpel dissection create a gaseous byproduct commonly referred to as surgical smoke or plume. SMOKE EVACUATION DEVICES have been shown to be effective in limiting...
-
From:Science (Vol. 301, Issue 5629) Peer-ReviewedIntense plumes of pollution downwind of Asia (eastward) and India (southwestward) have been documented. These plumes are due largely to industrial and vehicular emissions, biomass burning, and wind-blown dust. They have...
-
From:Science (Vol. 269, Issue 5229) Peer-ReviewedVolcanic eruptions of gassy magmas on Earth, Venus, and Mars produce plumes with markedly different fluid dynamics regimes. In large part the differences are caused by the differing atmospheric pressures and ratios of...

From:Atmospheric Chemistry and Physics (Vol. 19, Issue 2) Peer-Reviewed
Long-range-transported Canadian smoke layers in the stratosphere over northern France were detected by three lidar systems in August 2017. The peaked optical depth of the stratospheric smoke layer exceeds 0.20 at...

From:Oceanus (Vol. 48, Issue 3) Peer-ReviewedAlong with the torrent of hot gas and oil spewing from the seafloor, hot hints and rumors were also streaming out of the Gulf of Mexico in the spring of 2010. Some scientists on the scene of the Deepwater Horizon oil...
