Geotimes is the free electronic blog of the geosciences. Originally launched as GeoSpectrum, a newsletter of the American Geosciences Institute in 1995, Geotimes has been reborn as the go-to source of information on AGI's 51 Member Societies. The American Geosciences Institute coordinates and edits the blog, but it is the result of contributed materials from societies, geoscience organizations and others in the community.

Lidar sheds light on roadside rockfall hazard

Rockfalls represent a significant hazard on many U.S. roadways that wind through steep terrain. But with money tight for roadside hazard mitigation, engineers are looking for more efficient ways to assess where and when unstable slopes could give way. In a new study, researchers suggest that lidar might be a cost-effective solution.

Horned dinosaur find a first for eastern North America

Fossils of horned dinosaurs called ceratopsids, the group that includes Triceratops, are usually found in either western North America or Asia. But the discovery of a single ceratopsid tooth in Mississippi, reported in a new study in PeerJ, hints that this group spread into new territory at the tail end of the Mesozoic Era — just prior to going extinct.

Massive trove of dinosaur tracks cataloged in Australia

In a remote region of Western Australia, paleontologists have documented the world’s most diverse assemblage of dinosaur tracks. The scientists found preserved in Early Cretaceous rocks thousands of tracks, 150 of which can be assigned to at least 11, and possibly as many as 21, different known track types representing theropods, sauropods, ornithopods and armored thyreophorans.

In a position to lead: How military technology and innovation can ease the world's water challenges

Given the scale and resources of the U.S. military, as well as its need for resilient water systems wherever it operates, the military is driving innovation in the water sector, which could benefit communities around the world.

Bottom dropping out of coral reefs

Coral reefs provide habitat for 25 percent of all marine life, support fishing and tourism economies, and protect shorelines from surging waves and storms. But since the 1970s, coral populations have been waning because of warming waters, coastal development and pollution. Recently, scientists studying several beleaguered reef systems have discovered an unexpected consequence of their decline — the seafloor around the reefs is eroding, leaving coastal communities more vulnerable to high winds and waves.

Benchmarks: July 15-24, 1975: Apollo-Soyuz mission launches space collaboration

The space race between the United States and the Soviet Union spurred innovations and historic firsts for humankind from Sputnik to the moon landing. However, much of the drive to break through those technological barriers and explore the vast, starry landscape of space was rooted in a desire to display military dominance in space amid the competition and animosity of the Cold War.
