Elevated CO 2 affects shell dissolution rate but not calcification rate in a marine snail
As CO 2 levels increase in the atmosphere, so too do they in the sea. Although direct effects of moderately elevated CO 2 in sea water may be of little consequence, indirect effects may be profound. For example, lowered pH and calcium carbonate saturation states may influence both deposition and dis...

As CO 2 levels increase in the atmosphere, so too do they in the sea. Although direct effects of moderately elevated CO 2 in sea water may be of little consequence, indirect effects may be profound.
