National Fossil Day

From AGI  --  You are invited to join in celebration of the 5th Annual National Fossil Day on Wednesday, October 15, 2014. National Fossil Day is organized by the National Park Service as part of the American Geosciences Institute (AGI) Earth Science Week (http://www.earthsciweek.org) to promote public awareness and stewardship of fossils, with the goal of inspiring the next generation of paleontologists and fossil enthusiasts.

EARTH: How the Spanish Invasion Altered the Peruvian Coast

EARTH Magazine

From EARTH Magazine  --  When Francisco Pizarro landed in Peru in 1532, his band of Spanish conquistadors set off a chain of far-reaching consequences for the people and economics of western South America. The Chira Beach-Ridge Plain in northwestern Peru is rippled by a set of nine ridges — several meters tall by up to 300 meters wide and 40 kilometers long, and large enough to be visible from space — running parallel to the shoreline. The pattern, observed along at least five other Peruvian beaches, was thought to have formed naturally over the past 5,000 years.

EARTH: Santiaguito Volcano's Clockwork Behavior Provides an Exceptional Laboratory

EARTH Magazine

From EARTH Magazine  --  If Earth breathes, Santiaguito Volcano in the Western Highlands of Guatemala could be its mouth. Roughly every half hour, like volcanic clockwork, Santiaguito's active Caliente lava dome expands, filling with gas from depressurizing magma below. Then it exhales, often explosively, and deflates. Over the course of a day, you could almost keep time by it.

EARTH: Virtual Water - Tracking the Unseen Water in Goods and Resources

EARTH Magazine

From EARTH Magazine  --  "Virtual water" was coined in 1993 to help explain why long-predicted water wars driven by water and food security had not occurred among the arid nations of the Middle East and North Africa. The virtual water notion refers basically to the total amount of freshwater, either from rainfall or irrigation, used in the production of food commodities, including crops and fodder-fed livestock, or other goods and services - agricultural, industrial or otherwise.

Citizen Science the Focus of New Earth Science Week Site

Earth Science Week 2014

From AGI Public Relations  --  Science teachers and students can go online today to use a new educational resource of the Earth Science Week website, the "Be a Citizen Scientist" page, which features information and links for recommended "citizen science" programs focusing on Earth science.

Citizen science initiatives invite ordinary citizens to participate in scientific research by making observations and contributing to large data sets.

EARTH: La Brea climate Adaptation as Different as Cats and Dogs

EARTH Magazine

From EARTH Magazine  --  The La Brea tar pits in downtown Los Angeles are a famous predator trap. For every herbivore, a dozen or more carnivores - saber-toothed cats and dire wolves chief among them - are pulled from the prolific Pleistocene fossil site. In fact, the remains of more than 4,000 dire wolves have been excavated, along with more than 2,000 saber-toothed cats. The sheer number of fossils allows researchers to ask population-level questions about the climate and environment as well as how these animals evolved.
