... are known to have affected the substratum of Mississippi River as far upstream as New Orleans. The preponderance of the fresh-water deposits, at least of the surficial deposits, in the embayment area, laid down since the contraction and gulfward withdrawal of the transgressing waters to the present gulf...

... after the World Health Organization’s declaration of the pandemic, 65% of survey respondents agreed that COVID-19 had a significant impact on their work. Overall, 32% of respondents had experienced negative impacts on their employment, having either lost their jobs or been furloughed/temporarily laid...

...). These layers, which we consider correlative to the Eastern Mediterranean Sapropel Layers, range in age from the early Piacenzian to the Gelasian, and show surprising thicknesses, suggesting that they were probably laid down in a landlocked, overfed basin. Specifically, a thick laminite from the surroundings...

... the beds represent a primary record of volcanism. These and other lines of evidence indicate that postdepositional physical, biological, and geochemical processes (e.g., sedimentation rate, event, and background physical processes, burrowing) have modified the primary record of these water-laid ash-fall...

... of Singapore is about 640 km2. Of the three million residents, more than 85% live in high-rise buildings due to land short- age. Since Singapore is located in a low-seismicity area with mild winds, currently the structural design code for Singapore buildings does not consider seismic hazard explic- itly...

... be identified visually as having wind-ripple and grain-flow stratification were designated as alternating and are given a separate symbol in Figure 5 . Alternating grain-flow and wind-ripple core plugs have an intermediate permeability range. Figure 5 —Permeability vs. porosity diagram for core plugs...

... in water content, and the cross-hatched circle marks the location of x̄ ( t ). Fig. 3. A soil column is suspended at the drying end, F 0 , and at the sealed end, F 1 , by a load cell. Imposed on the soil column is a graph of water content vs. distance from the drying face, ϴ( x, t ). The gray...

...–700 m within the area defined. This supports the previous hypotheses of Bruun (1943) and Clarke (1969 , 1970 ) that the eggs are laid on the ocean floor and that S. spirula hatches in cool water <1000 m deep, where Spirula spends its juvenile stage. An alternative explanation...

... discharges with high-magnitude peak flows). Pseudomorphs after gypsum, impressions of wind-accumulated gypsum crystals, and desiccation cracks indicate strong evaporation, and adhesions ripples and warts indicate strong wind action ( Stear 1978 ). Whereas falling water level marks and color mottling reflect...

... noise contributions for both sensor types and improve characterization of sources that occur close to the solid earth–atmosphere boundary. Because sensors are installed to target these broadband acoustic sources, considerations need to be made when selecting a mechanical wind filter to mitigate...

... of loose deposits and loess. This kind of topography is conducive to the accumulation of rainfall and groundwater to the river, causing soil erosion and other disasters. It has a wide range of soil erosion and great intensity, and the region is characterized by water erosion, wind erosion, gravity erosion...

... and dispersal, particularly along western margins ( Wright and Burchette 1996 ). Nearshore waters of the island are affected by strong currents (long-shore currents) and by waves that are forced by easterly winds from the Atlantic Ocean ( Gerace et al. 1998 ; Horwitz and Roberts 2010 ). Moreover, easterly...

... Borealis,” at least for geologically short episodes, has been found to be generally consistent with considerable geomophological evidence. The distinctive water-laid sedimentary deposits that cover parts of the northern plains, known as the Vastitas Borealis Formation, afford the most convincing evidence...

... with an active layer up to 10 m thick. Pipelines laid within the secondary dune network would potentially be exposed to additional loading or the loss of support to the pipe in areas of severe wind scour on and around actively mobile dunes (e.g. during the course of a single storm), causing pipe exposure...
