Description:
Conversion of dissolved manganese to particulate manganese occurred during a minor diatom bloom during August and September 1978 in the MERL microcosms. Correlations between chlorophyll a and particulate manganese suggest that 29 moles Mn were transferred to the particulate phase for every mole of chlorophyll formed during the active growth of the diatoms. The particulate manganese formed was primarily removed to the sediments after the bloom terminated. The ability to sample large controlled ecosystems repeatedly over short time scales provides a system in which the geochemical cycle of manganese can be readily modeled.
