As scientists search for life on Mars, they should take a close look at rock varnish, according to a paper in the current issue of the "Journal of Geophysical Research."
Hurricane Ike reconfirmed one Texas researcher's idea: Interfering with Galveston Island's natural elevation hurts the island's sand dunes and marsh flora. Ike reconfirmed the basic idea I've had for several years, Rusty Feagin, ecosystem scientist with Texas AgriLife Research at Texas A&M University, said in a news release.
Dr. Rusty Feagin was managing several ecosystem research projects on Galveston Island when the 2008 hurricane season began.Then he got an unexpected visit from a research assistant named Ike."Ike reconfirmed the basic idea I've had for several years," said Feagin, ecosystem scientist with Texas AgriLife Research. "The plants on sand dunes and in marshes build an island's elevation, so we shouldn't compromise that."Most of the dunes and marshes he and his graduate students had studied were...

A river delta is a landform that is created at the mouth of a river, where the river flows into an ocean, estuary, lake, sea, or reservoir. These deltas are built from the deposition of the sediment that is carried by the river as the flow exit’s the mouth of the river. Over a long period of time, this deposition constructs the distinctive geographic pattern of a river delta. The creation of a delta is made up of three core forms: the bottomset, topset, and foreset/frontset. Bottomset...
In geology, a conglomerate is a rock consisting of other stones that have been cemented together. Conglomerates are sedimentary rocks consisting of subangular clasts and are thus differentiated from breccias, which consist of angular clasts. Both conglomerates and breccias are characterized by clasts larger than sand (>2 mm). There are two varieties of conglomerate, defined by texture: paraconglomerates and orthoconglomerates. Paraconglomerates are one of two varieties of conglomerate...
