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]

Water Series (3): Arsenic Contamination in Drinking Water
Following our post about fluoride contamination last week, our water series is now focused on the equally serious problem of arsenic contamination. Some arsenic is present in all groundwater sources (see table 1). Of course this is only a problem if the arsenic has the chance to leak into groundwater as it filters through the rock. Arsenic leaching is more likely to occur in groundwater that is ho ...[Read More]

The earthquake, which is estimated to have had a magnitude of 8, had an epicentre close to Valdivia, and was accompanied by significant ground shaking and subsidence as far south as Chiloe island, and a major tsunami that reached Hawaii. The eyewitness reports of the time have been well ...[Read More]

Water Series (2): Fluoride Contamination in Drinking Water
This week, as part of our ‘water series’ we will focus on fluoride contamination in drinking water. In some parts of the UK we add fluoride to our drinking water, because small amounts can help to protect your teeth. However, too much fluoride (>1.5mg/L) can lead to a serious medical condition called fluorosis, affecting the development of teeth and bones. This strong dosage dependency can lead ...[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 ...[Read More]
