Understanding Travel Patterns Of Microbes Blowing In The Wind
2013-02-07 09:32:18

U.S. Department of Agriculture (USDA) With help from a wind tunnel and the latest DNA technology, U.S. Department of Agriculture (USDA) scientists are shedding light on the travel patterns of microbes in soils carried off by strong winds. The work has implications for soil health and could lead to management practices that minimize the damage to soils caused by wind erosion. Wind erosion is an emerging issue in soil conservation efforts. Agricultural Research Service (ARS) scientists...

Geologist Find Unusual Land Formation On Mars
2012-03-23 06:10:46

Geologists at the University of Washington found that a previously unseen landform on Mars could help provide a window into the geological history of the Red Planet. The "periodic bedrock ridges", or PBRs, look like sand dunes, but the scientists say that they are actually made from wind erosion of bedrock. "These bedforms look for all the world like sand dunes but they are carved into hard rock by wind," David Montgomery, a UW professor of Earth and space sciences, said in a press...

Drier conditions projected to result from climate change in the Southwest will likely reduce perennial vegetation cover and result in increased dust storm activity in the future, according to a new study by scientists with the U.S. Geological Survey and the University of California, Los Angeles. The research team examined climate, vegetation and soil measurements collected over a 20-year period in Arches and Canyonlands National Parks in southeastern Utah. Long-term data indicated that...

Pebbles that become part of clastic rocks in places like Arizona's Lower Antelope Canyon don't move with the wind but against it, a geosciences professor said. Rather than being pushed into formations, the pebbles, or clasts, have the loose sand around them removed by the wind, Andrew Leier of the University of Calgary said in the journal Geology. The sand removal causes scour-pits to form on the wind side of larger clasts, and the pebbles eventually fall toward the wind into the scours, he...

At first, figuring out how pebble-sized rocks organize themselves in evenly-spaced patterns in sand seemed simple and even intuitive. But once Andrew Leier, an assistant geoscience professor at the U of C, started observing, he discovered that the most commonly held notions did not apply. And even more surprising, was that his findings revealed answers to NASA's questions about sediment transport and surface processes on Mars. Those results are published in this month's edition of Geology....

NASA -- Typically we think of rainfall as cleaning the air by removing dust as it falls through the atmosphere and helping plants grow that protect and hold the soil. But a new NASA-funded study looking at some of the world's dustiest areas shows that heavy downpours can eventually lead to more dust being released into the atmosphere. Typically drought reduces vegetation growth, increasing soil vulnerability to wind erosion, while rainfall tends to have the opposite effect. In the new study...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
