Abstract
The fate of phytoplankton detritus in the muddy sediments of shallow marine ecosystems was studied by labelling the water column of a 13 m3 microcosm with radiocarbon bicarbonate. Demonstrates that time lags on the order of months can exist between the deposition and mineralization of phytoplankton detritus in nature. Observed time lags may have occurred because heterotrophic activity was minimized by low winter and spring temperatures, pelagic and benthic grazing was minimal, and bioturbation rates were high. -from Authors
