Ocean acidification could be described as climate change’s evil twin, not that it needs one. The world’s oceans are partly absorbing the carbon dioxide we are pumping into the planet’s atmosphere, which then reacts with seawater and forms carbonic acid. This process decreases the pH of the oceans, making them more acidic. If you are a crab resident of the ocean, this is not good news. Norma ...[Read More]
GeoSciences Column: The dirty business of shipping goods by sea
Shipping goods across the oceans is cost-effective and super-efficient; that’s why over 80% of world trade is carried by sea (according to the International Maritime Organisation). But the shipping industry also contributes significant amounts of air pollutants to marine and coastal environments. A new study, published in the EGU’s open access journal Earth System Dynamics, reports on concentratio ...[Read More]
June GeoRoundUp: the best of the Earth sciences from around the web
Drawing inspiration from popular stories on our social media channels, as well as unique and quirky research news, this monthly column aims to bring you the best of the Earth and planetary sciences from around the web. Major Story With June being the month when the world’s oceans are celebrated with World Ocean Day (8th June) and the month when the UN’s Ocean Conference took place, it seemed apt t ...[Read More]
Geosciences Column: Larvae, Climate and Calcification
The absorption of atmospheric CO2 by the oceans results in a decline in ocean pH, hence ‘ocean acidification’, and reduces the availability of carbonate. This presents a problem to calcifying organisms (those that deposit calcium as either calcite or aragonite as hard parts) because they cannot produce their shells, valves (in the case of bivalves), or tests (in the case of diatoms) as readily. To ...[Read More]
