This week Sonardyne announced the integration of its CONTROS HydroC dissolved CO2 sensor from -4H-JENA engineering into its Origin 600 Acoustic Doppler Current Profiler, a development aimed at unlocking new capabilities for ocean acidification research.
The combined solution enables precise, real-time monitoring of dissolved carbon dioxide levels alongside detailed current profiling.
The oceans act as a partial sink for atmospheric CO2, so more CO2 means more acidification, even in deep oceanic waters.
The effects on ecosystems and biodiversity have been clearly observed, and food production from shellfish aquaculture and fisheries has suffered.
The World Meteorological Organization’s latest State of the Global Climate report released in March confirmed that acidification of the ocean surface is continuing, demonstrated by the steady decrease of global average ocean surface pH. The most intense regional decreases are in the Indian Ocean, the Southern Ocean, the eastern equatorial Pacific Ocean, the northern tropical Pacific and some regions in the Atlantic Ocean.
Projections show that ocean acidification will continue to increase in the 21st century at rates dependent on future emissions, and the report points out that changes in deep-ocean pH are irreversible on centennial to millennial time scales.
