Ocean acidification Halflogo2

Temperature, light and nutrients are oftern determined as the most important external physical variables on the marine ecosystem, however the impact of anthropogenic CO2 directly influencing the pH of of the oceans is now a growing concern.

Evidence collecter and modelled indicates that rising CO2 has lead to chemical changes in the oceans which results in the sea water becoming more acidic.  Ocean acidificiation has the potential to affect the process of calcification and therefore certain plankton such as foraminfera, coccolithophores and pelagic molluscs could be vulnerable to future CO2 emissions.

Warming of the oceans will also create chemical changes dramatically altering the oceans ability to absorb additional atmospheric CO2.  This could affect the overal scale of climate warming.

The CPR survey provides crucial baseline data and SAHFOS is currently monitoring the abundance and distribution of the these vulnerable organisms.
