Abstract

A marked increase in the rate of CO2 outgassing due to volcanic activity between about 110 and 70Ma may have resulted in a buildup of atmospheric CO2. A significant fraction of this atmospheric CO2 may have been reduced by an increase in the production and burial of terrestrial organic carbon. Some excess CO2 may have been consumed by marine algal photosynthesis, but marine productivity apparently was low during the Aptian-Albian relative to terrestrial productivity. Terrestrial productivity also may have been stimulated by increased rainfall that resulted from a warm global climate and increased marine transgression as well as by the higher CO2. -Authors
