Sapropels deposited in the Mediterranean Sea provide high resolution records of past oceanographic changes. Previous studies have found abrupt transitions in chemical composition of these sediments. We present a transient box model that provides a potential mechanism for these transitions. The high-frequency variability is a result of fluxes stopping or changing direction, causing a relaxation towards a new equilibrium. The time scales depend on the volume of the reservoirs and the magnitude of the fluxes. We find typical periods in the order of 100-1000 years, similar to what has been found in sediment cores.
