Collapsing dams are a staple of disaster films, but the form that these take in natural systems is also surprisingly varied. Streams and rivers can be blocked by a range of rapid and gradual inputs. One of the lesser-known causes of stream blockage is through the accumulation of large woody debris – tree trunks and large branches – to form a log jam. The impact of these jams on river geomorphology ...[Read More]

Geoscience communication: A smart investment

In this post, originally published in June 2017 on the blog of the Geological Society of America (GSA), Terri Cook, a science and travel writer and former winner of the EGU’s Science Journalism Fellowship, argues the importance of quality science communication as a means for scientists to make their research accessible to a broad audience. One way to achieve this is working with a science jo ...[Read More]
