By Ned Rozell Leaving cloven hoof prints from the Yukon-Kuskokwim Delta to the Arctic National Wildlife Refuge, more than 3,500 muskoxen live in Alaska. All of those shaggy, curly-horned beasts came from one group of muskoxen that survived a most remarkable journey in the 1930s. In 1900, no muskoxen existed in Alaska. Though the stocky, weatherproof creatures have survived in the Arctic since the last ice age, the last reports …

“Chances are good that the drop of rain that splashes on your forehead is made of molecules that were here long before the first humans looked up in wonder at a cloudy sky, long before the first leafy plants stretched their roots into the soil, long before the first single-celled organisms took the critical step of dividing in half to reproduce.”

A newly-released LiDAR data set reveals impressive ridge-top cracks associated with large rock slides in the Virginia Valley and Ridge. While the cracks are easily visible with LiDAR hillshade imagery, they appear to be covered by normal forest vegetation and would probably look like elongated depressions in the forest.

Update 11:00 AM EDT Indonesia’s Mt. Agung may be on the cusp of its first eruption since 1963, an eruption that killed more than 1000 people. Since late August, seismic signals have increased in frequency, and last Friday, officials raised the alert status to the highest level. Local officials have evacuated around 75,000 people from the area and warned residents to keep an 8-12 kilometer distance from the volcano. However, it’s still unclear whether—or when—the volcano may erupt, …

Sometimes you have to build the field in the laboratory (or in this post’s case, in the art museum). At the Virginia Tech Active Tectonics and Geomorphology Lab they do just that. This is the latest in a series of posts shared from their blog. More of their posts can be found here. Written by The Geo Models Part 3 (final part) of a 3 part series on the valleys and …

Zooplankton is certainly not the study focus of Oliver’s working group, but for a while, these small crustaceans become a reminder of the complexity of the oceans’ systems. Every working team onboard has specific questions they would like to see answered, but on top of those, they are all always attentive for new learning opportunities.
