AZTI installs a sensor for monitoring ocean acidification in the Basque coastal ocean
AZTI has installed a new sensor for monitoring ocean acidification on the Basque Coast. It has been installed around 3 kilometres from the coast at a depth of around 50 metres. The sensor is a stand-alone instrument that determines the pH of seawater using a high-precision colorimetric reagent. The equipment can be anchored in the open sea at a depth of up to 600 metres, and provides accurate hourly pH readings for several months. It will give regular data about changes in pH in the Bay of Biscay which will be used to calculate acidification levels.
The initiative is part of action C.9.1: Climate change hub: Observation and monitoring system.
