CO2-induced acidification affects hatching success in Calanus finmarchicus
ABSTRACT: Bottle incubations were conducted to examine how exposure to seawater containing 8000 ppm carbon dioxide (CO2; pH 6.95) influenced the growth and reproduction of the keystone copepod Calanus finmarchicus. The chosen concentration of CO2 is expected to occur over 100s of cubic kilometres of...
