Atmospheric acidity impacts oceanic ecology
Increased acidity in the atmosphere is disrupting the ecological balance of the oceans, according to new research led by the University of East Anglia (UEA). The first study to look at acidity’s impact on nutrient transport to the ocean demonstrates that the way nutrients are delivered affects the productivity of the ocean and its ability to absorb CO2 from the atmosphere. The research, ‘Changing atmospheric acidity as a modulator of nutrient deposition and ocean biogeochemistry’, is published today in Science Advances. The analysis was carried out by an international team of experts, sponsored by the United Nations Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP).
