Geosciences Column: Following Fukushima: what happened to the iodine isotopes?

The March 2011 earthquake, 130 km off the coast of Japan, resulted in a 10-40 m high tsunami inundating Japan’s Pacific coast and caused the release of radionuclides from Fukushima Daiichi Nuclear Power Plant (NPP).  The demise of three of the reactors was widely covered in the media, with worldwide coverage of the potential effects of radiation release both close to the plant and further afield. ...[Read More]

Geosciences Column: How curbing HFC emissions could reduce warming

Carbon dioxide is without a doubt the most famous of warming culprits. But would reducing emissions of this greenhouse gas be enough to mitigate climate change within this century? A recent paper published in Atmospheric Chemistry and Physics focuses on a less known substance that, if phased out, could avoid as much as 0.5 °C of warming by 2100. Hydroflurocarbons (HFCs) have an interesting history ...[Read More]

GeoTalk: Suzanne Hangx on Carbon Capture & Storage

Today in GeoTalk, we’re talking to Suzanne Hangx, who explains the great potential of carbon capture and storage and the challenges emerging technologies, like CCS, face. First, could you introduce yourself and let us know what drew you to geomechanics? Let’s start with the introduction: I’m Suzanne Hangx and I currently work as a researcher on geomechanics for subsurface storage containment techn ...[Read More]

Bioengineering Could be the Answer to Dirt-Free Dams

Scientists are building walls of willow trees in the Southern French Alps gullies to trap dirt that blocks hydroelectric dams downstream. Sediment in rainwater washes off the steep valley slopes in the Francon marly basin into gullies. These smaller waterways then feed larger rivers. When the water reaches the slower-moving reservoirs above dams, the sediment drops out and settles behind the barra ...[Read More]
