AN IMPROVED PROTOCOL FOR CLEANING OF PLANKTONIC FORAMINIFERA FOR SHELL WEIGHT MEASUREMENT
The shell weights of planktonic foraminifera can be used as a proxy to reconstruct seawater [CO32-] in the past and, therefore, to provide clues regarding the ocean carbon cycle. Foraminiferal shells must be cleaned prior to weight measurements in order to remove detritus trapped within the shell ch...
