Algal sedimentation in relation to phytoplankton periodicity in Rostherne Mere

Abstract
Algal remains recovered from sediment traps in Rostherne Mere, Cheshire, broadly reflected the phytoplankton periodicity and suggested that the turbulent resuspension of sedimented material occurs infrequently. Quantitative comparisons between the standing crops and the algal fluxes intercepted by sediment traps indicated that the cylindrical traps yielded accurate estimates when operated in weakly turbulent waters but apparently exaggerated the fluxes when operated in turbulent conditions.
