Imaggeo on Mondays: Light reflection

In this week’s Imaggeo on Mondays, brought to you by the photographer herself, Jacqueline Isabella Gisen (Delft University of Technology, The Netherlands) tells us about light refraction and reflection in a beautiful Autumnal landscape. This shot was taken spontaneously on my way to Clingendael Park in The Hague, Netherlands, for an Autumn’s photography activity on 4 October 2011. It was misty and ...[Read More]

Geotalk: Dr Olivier Galland

GeoTalk, featuring short interviews with geoscientists about their research, continues this month with a Q&A with Dr Olivier Galland (University of Oslo), who tells us about his volcanology research and the importance of outreach in promoting the Earth sciences. If you’d like to suggest a scientist for an interview, please contact Bárbara Ferreira. First, could you introduce yourself and ...[Read More]

Imaggeo on Mondays: The power of ice

There has been a lot of talk about Greenland lately in the context of global climate change. And for good reason. Over 80% of its total surface is covered by ice, the volume of which exceeds 2,850,000 km3 or enough to raise global sea levels by a staggering 7 m if fully melted. The Greenland ice sheet consists of layers of compressed snow from over 100,000 years of snowfall. As a result, ice cores ...[Read More]

Geosciences Column: Human-induced changes in the ocean’s salinity and temperature fields

In this month’s Geosciences column, Mona Behl discusses a recent paper on the effects of anthropogenically-induced climate change on the planet’s oceans.  A recent study led by scientists at the Scripps Institute of Oceanography, University of California San Diego, suggests that observed changes in ocean salinity are inconsistent with natural climate variations and can be attributed to human ...[Read More]
