This week’s Imaggeo on Mondays stars the humble sea urchin – a creature suffering from the effects of climate change, but one that could also provide a way to sequester some of the CO2 responsible… Carbon dioxide and water react to form carbonic acid – a mixture of bicarbonate and hydrogen ions. Sea urchins bag the bicarbonate to grow bigger, stronger shells, or ‘tests’, but without a catalyst, th ...[Read More]
Imaggeo on Mondays: Long live the lichen!
Lichens are amazing organisms. They are a composite of algae and fungi, each of which supports the other through the exchange of nutrients (fungi to algae) and carbon (algae to fungi). They are also capable of making a home out of seemingly inhospitable rock surfaces – and what’s more – making the most of these surfaces to release the nutrients they need to grow. The quartzite above is home to the ...[Read More]
Put it in a nutshell – or in this case a 21 ft container
In his final post from the Floating University, Jens Weiser shares what it’s like to be part of an oceanographic research cruise and sums up some of the best experiences he’s had on board… I started this series asking whether anyone of you had ever thought about joining a research cruise. Now that this cruise is coming to an end, I can only strongly advise everyone who might have responded t ...[Read More]
A dangerous fish in the lab and a Vibrocorer on the move – who said research was monotonous?
Earlier this month Jens Weiser set off aboard a research vessel fondly known as the Floating University to find out more about the oceans off southern Africa. After several weeks at sea, Weiser has some exciting findings to report back from FS Meteor as he and 14 other young scientists explore the region’s biology and geology… A certain routine has developed over the last week here on board. The t ...[Read More]
