Alexandria, VA — It’s 3 a.m., and students from two Oregon community colleges are struggling to keep their sea legs as they work on the deck of a research vessel that is pitching and rolling in rough seas. Their objective is to recover an ocean-bottom seismometer that has been lying 160 meters underwater off the west coast of Vancouver Island, where it has been steadily recording seismic signals and long-period pressure trends for the past year.

Alexandria, VA — The newest edition of the Directory of Geoscience Departments is now available for purchase in print and as an eBook. As the cornerstone reference publication of the American Geosciences Institute, the 48th edition of the Directory of Geoscience Departments is an invaluable resource for those working in the geosciences, those who must identify experts with specialties in various geoscience fields, or students investigating potential programs to study.

Alexandria, VA- When Apollo 17 splashed down in the Pacific Ocean on Dec. 19, 1972, it marked the end of spaceflight to the moon. The science, however, continues. Armed with analytical techniques not available in the 1970s, researchers around the country have been re-examining the more than 380 kilograms of lunar rocks collected four decades ago during the Apollo missions. Using new investigations, such as petrographic and chemical composition studies and updated solar radiation and engineering measurements, these “cold case” scientists, many of them young innovators, are extracting new knowledge about our nearest celestial neighbor.

Alexandria, VA — Much like our voices create sound waves with a variety of low and high pitches, or frequencies, earthquakes produce seismic waves over a broad spectrum. The seismic waves’ frequencies determine, in part, how far they travel and how damaging they are to human-made structures. However, the inaccessibility of fault zones means that very little is known about why and how earthquakes produce different frequencies. With the help of a new tabletop model, scientists have now identified how a process known as fault healing can shape seismic waves and potentially alter their frequencies. [Read More]

As the Colorado River winds through the Colorado Plateau’s soft sedimentary strata, it picks up a tremendous amount of sediment. This sediment — which once left the river’s waters so muddy that Spanish explorers christened it El Rio Colorado “the reddish river” — is a vital component to the unique ecosystems of the river. However, with the construction of the Hoover and Glen Canyon dams, which trap the sediment, the once-turbid waters have become a dazzling blue-green, signaling major changes with serious implications for the health of the river’s native [Read More]

Alexandria, VA - The American Geosciences Institute (AGI) is proud to support National Groundwater Awareness Week, March 10-16, 2013. Groundwater is a crucial source of fresh water for society, both in terms of potable water, agricultural, and industrial needs. The United States alone uses 79.6 billion gallons of groundwater per day for public and private drinking water, irrigation, livestock, manufacturing, mining, thermoelectric power, and other purposes. While freshwater accounts for less than 3% of all water on Earth, groundwater makes up roughly 99% of that 3%. [Read More]

Alexandria, VA — Beginning today, the Federal Government’s discretionary spending accounts will be cut by $85 billion through the rest of the fiscal year. These across-the-board spending reductions, known as the sequester, were first proposed in 2011 as a penalty so severe they would force Congress to work together to solve the nation’s deficit woes. Unfortunately, no agreement on a package of replacement cuts or additional revenue in time to avoid the sequester has been made. [Read More]

Alexandria, VA - The American Geosciences Institute (AGI) and American Geophysical Union (AGU) have released a recording of the latest AGU/AGI Heads and Chairs webinar. This month’s session focuses on legal issues related to field trips and field courses. Although field work is acknowledged as an integral part in geoscience education and research, it exposes geoscience departments to legal and safety liabilities. The video provides preemptive tips to conduct a safe field trip or course by minimizing risk and liability through careful planning. [Read More]

On June 5, 2012, a massive dock made landfall on Oregon’s Agate Beach, just north of Newport. The dock carried with it a host of castaways, including as many as a hundred species of mollusks, anemones, sponges, oysters, crabs, barnacles, worms, sea stars, mussels and sea urchins. A placard on the side written in Japanese revealed that the dock had been unmoored from the Japanese coastal city of Misawa during the catastrophic tsunami on March 11, 2011, bringing with it an essentially intact subtidal community of Asian species to the Pacific Northwest.

Kelly M. Deuerling, a Ph.D. candidate and NSF Graduate Research Fellow at the University of Florida, was selected as the first recipient of the new scholarship dedicated to increasing the number of women in geoscientific professions. Deuerling was selected for her outstanding contributions to her field, extracurricular activities, and strong participation in the geoscience community. Deuerling is a highly accomplished geoscientist with a wide range of field experiences, lab skills, grants, and awards to support her research, as well as a publication in review. [Read More]
