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]

Sandwiched between the U.S states of Mayland, Delaware, Pennsylvania, New York State, the District of Columbia and Virginia, lies Chesapeake Bay, the largest estuary in North America. It is of huge ecological importance: “the bay, its rivers, wetlands and forests provide homes, food and protection for countless animals and plants”, says the Chesapeake Bay Program. Up to 150 major rivers and stream ...[Read More]

Geotalk is a regular feature highlighting early career researchers and their work. Following the EGU General Assembly, we spoke to Yadong Sun, the winner of a 2017 Arne Richter Award for Outstanding Early Career Scientists, about his work on understanding mass-extinctions. Using a unique combination of sedimentological, palaeontological and geochemical techniques Yadong was able to identify some o ...[Read More]
