All measurements of the atmospheric input term, Sin have been confined to deep water situations. Hence, current knowledge of this mechanism is restricted to extrapolations of the deep water theory. Deep water forms of Sin are generally related in some way to the ratio U10/C [e.g. (4.44)]...
One chart shows the magnitude of acoustic interference from reflecting surfaces when continuous-wave measurements are made on an omni-directional transducer. Two charts show the interdependence of transducer size, transducer Q, test depth, test distance, and frequency for pulsed-sound measurements. (...
In-situ monitoring begins with handheld sensors. Today, handhelds remain a mainstay of water quality monitoring fieldwork, allowing people to gather lab-quality measurements in the field. They have made water quality testing more efficient and timelier, as they can capture measurements of parameters...
Combining underwater imaging with water mass and circulation measurements, molecular sequencing techniques and model calculations, we show that dense water-driven carbon injection may provide an important pathway for Arctic carbon sequestration. Bottom water-associated lateral particle transport...
In some cases, Es was estimated from irradiance measurements below the water surface (just below the surface: Ed(0-), or at depth z: Ed(z)). These measurements are typical of autonomous installations on vertical sensor chains or a single sensor package on a vertically profiling platform44. ...
40 pvc pipe is stated as a nominal figure, please see chart in photos for actual measurements. This means 2″ ID is NOT exactly 2″ ID. ALL manufacturers make this pipe the exact same way. It is very expensive, time consuming and aggravating to locate and replace a piece of pipe that...
To be most effective, physical barriers must be applied either at the time that mine-waste deposition ceases or shortly thereafter. The rate of sulfide oxidation is greatest immediately after mine-waste deposition ceases, whereupon the moisture content declines. Measurements of concentrations of dissolve...
地下水深度与地下水储存量之间的换算 A specifific yield of 0.081 was derived from Beijing Water Resources Bulletins to estimate GWS changes using GW depth measurements made at 110 wells in the Beijing Plain(@@用的grace的地下水储量数据进行的换算吗? 支撑材料提供了地下水深度图) ...
Brad Buecker is president of Buecker & Associates, LLC, and most recently he served as Senior Technical Publicist with ChemTreat, Inc. He has over four decades of experience in or supporting the power industry, much of it in steam generation chemistry, water treatment, and air quality control....
groundwater samples reached 107cells mL−1(Fig.4). Overall, microbial cell numbers across the entire studied region, did not decrease with depth (Supplementary Fig.2a, b). Cell counts were on average slightly higher in aquifers in geologic strata that contained shales or coal (Supplementary ...
