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 …[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-induced …[Read More]
Imaggeo on Mondays: Blue haze
In this week’s Imaggeo on Mondays, brought to you by the photographer himself, Lukas Hörtnagl (University of Innsbruck, Austria) tells us about the ‘blue haze’ or ‘tule fog’ of California’s Sequoia National Park.

The cover of their third studio album, Porcupine (1983), features the band nonchalantly standing in front of the gushing white foam of Iceland’s Gullfoss waterfall. Mentioned in local written stories and beamed across the world in …[Read More]
GeoTalk: Dr Stephanie Henson
GeoTalk, featuring short interviews with geoscientists about their research, continues this month with a Q&A with Dr Stephanie Henson (University of Southampton) who tells us about her work on marine ecosystems, and gives great advice to young scientists. If you’d like to suggest a scientist for an interview, please contact Bárbara Ferreira. First, could you introduce …[Read More]
Imaggeo on Mondays: Lake Louise, Alberta
The Canadian province of Alberta is known for its seemingly endless and pristine natural landscapes and the area surrounding Lake Louise, in Banff National Park, is no exception. Located at the foot of the Rocky Mountains, Lake Louise boasts a unique emerald colour as a result of rock flour – fine-grained, silt-sized particles of rock …[Read More]

Geosciences Column: The Longyearbyen CO2 Lab – Drilling for a greener future
In this month’s Geosciences column, Ingrid Anell introduces Norway’s Longyearbyen carbon capture and storage project and presents its first results. The world’s northernmost community, Longyearbyen, located at latitude 78 degrees north, is making progress towards becoming the world’s first CO2 neutral community. Geologists at UNIS, the University Centre in Svalbard, have determined that just a few kilometres …[Read More]
