Earlier methods for absolute diatom frequency analysis were timeconsuming. In pollen analysis the use of indicator pollen and spores is well established. This method has been tested for absolute diatom analysis and proved to simplify the work. A detailed preparation procedure is given. A method for combined pollen and diatom analysis has been worked out to check the diatom production curves in sediments where the deposition rates can not be measured by 14 C–dates or yearly laminated sediments. Diatom frequencies are here compared with synchronous terrestrial pollen frequencies. This gives an independent picture of changes in diatom productivity.
