Rivers frozen

Beyond the town lay the river, frozen, dark and still and beyond that again shone the lights of the neighboring city. Was his boy over there beyond that dark, silent river Was he over there in the city in some one of those dens of iniquity which had lured so many young men to their ruin ... 

The primary cost variable in barge shipments is fuel a midsize towboat can consume 5000 gal (18.9 kl) of diesel fuel daily. Barge shipments are also dependent on weather conditions low water or frozen rivers and canals can halt shipments. As ivith ocean vessels, the barges that move coal also ship other bulk commodities, making the rates and availability of barges for coal shipments dependent on conditions in other markets. Backliaiils (i.e., shipment of one commodity to a terminal and return with a different product) can substantially reduce coal rates. 

Additionally, an in situ experiment was performed to evaluate HBCD bioaccumulation. In site C5, clean barbels were exposed to the environment. As a control, the same experiment was performed in site C2. Twenty specimens of barbel were caged into each one of two stainless steel devices that were placed on the river-bed at the two locations. Nine specimens were immediately frozen to be analyzed as blanks. After 15 days of exposure, no mortality was observed in the cages. Table 4 shows levels of HBCD accumulated in the caged barbels exposed in sites C2 and C5. Accumulation at site C2 was negligible, as values measured after the exposure were even lower than those of the fishes not exposed. However, at site C5, after the... 

I walked closer to this apparition and bent toward the flame. The fire appeared still, absolutely frozen. My mind shot back to the moment above the river when it too had seemed stilled forever. The flame was uncanny. As deeply as I cared to look into it I could see no movement of particles or gas. I seemed to have my usual freedom of movement, but the world around me was coming to a crystalline and eerie halt. 

As we watched, suddenly Ev gasped. From the seething base of the cloud what looked like a column of light emerged. The column was sustained, not merely a bolt of lightning. It was hard to see how it could be a shaft of sunlight, since it was late afternoon and the sun was in the west, while the cloud was in the southeast. We watched it for perhaps a minute. Then it stopped abruptly. Ev was quite shaken. Even more than the frozen appearance of the river, this occurrence was of an empirical order different than anything that she had experienced at La Chorrera. 

Frozen rain and frost collected at a site close to a heavy traffic road as well as ground and river water were irradiated by y-rays at 77K. Signals of SO and N032 were observed121 in addition to paramagnetic ions such as Fe3+ and Mn2+. The reaction when OH radicals are annealed out is structure sensitive. 

Environmental assessment of natural water may be made through irradiation of the frozen water by UV-light. UV-irradiation of ice frozen from ground and river water gave more intense signals of N02 than those of OH radicals. 

A few studies to monitor our environment with ESR are included in this section. The ESR dating of marine terraces using shells and corals determined the age of the high sea levels and the tectonic uplift of islands.1 The variation of S03 indicated global environmental effect of volcanic eruption.1 ESR spectra of frozen rains, snow and frost as well as ground and river water indicated some...

About 97.2 percent of Earth s water is saline (salty) ocean water. Another 2.14 percent is fresh water frozen in polar ice caps and glaciers. All the remaining water, less than 1 percent of Earth s total, comprises water vapor in the atmosphere, water in the ground, and water in rivers and lakes—the fresh water we rely on in our daily lives. 

Have you ever wondered what happens to the animals in frozen rivers and lakes during the winter Long ago, scientists used to think marine animals were able to freeze in winter and thaw in summer, but today we know this is not the case. Many fish and turtles, for example, have developed ways to avoid freezing while storing themselves over the winter in near-frozen environments. 

The World Glacier Monitoring Service at the University of Zurich reviewed 30 glaciers in 9 mountain regions, including the moving frozen rivers of the Andes, Himalayas, and elsewhere. Its members concluded that the loss of glaciers will reduce summertime sources of river water and therefore will... 

The river deposited a thick layer of mud as it receded. To stop all biological growth and to preserve the library s contents, all books, file drawer materials, object catalogs, photographs, and journals were frozen. This action permitted the staff to consider and to evaluate restoration methods. 

In the last ice age, when much of the water of the world s oceans was frozen as ice and sea levels were lower than they are now, the coasdines extended past their present positions. Then, as now, many rivers flowed to the sea, cutting deep, V-shaped valleys as they went. Thousands of years later, when much of the ice caps melted and sea levels rose, water filled in, or drowned, these river troughs. The type of coast that is dominated by an old river valley is called a drowned river, or ria coast (after the Spanish term ria, which means estuary ). The Chesapeake Bay is a good example of this type of coastline. 

Sediment samples were collected using a grab sampler (which samples approximately the top 10 cm) aboard Old Dominion University s research vessels, ODU-1 and Linwood Hoi Con. The sample locations are shown In Figure 1. The samples were stored frozen In clean, solvent-washed jars until analyzed. Creosoted wood samples were collected from areas adjacent to the Elizabeth River (Figure 1). Three samples of refined creosote and one sample of coal tar were also analyzed. Creosote samples from Atlantic Wood Industries, the remaining operative creosotlng facility on the Elizabeth River, were not available. The woodstove soot sample was obtained from a domestic woodstove in which predominantly hardwoods were burned.
