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]

In this case, we were close to Aguereberry Point, a mountain viewpoint located at 1961m above sea level, overlooking the central part of this “vast ...[Read More]

Imaggeo on Mondays: Gullfoss, Iceland

For anyone who spent the 1980s jamming to British band Echo & the Bunnymen, this is a familiar sight. 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 music videos, the Gullfoss falls occupy a mythical place in hum ...[Read More]

First, could you introduce yourself and let us ...[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 – carried into the lake by meltwater from nearby mountain glaci ...[Read More]
