Summary: A high-resolution molecular stratigraphical record of chlorin concentrations (the pigment-transformation products of chlorophyll) over the past 350 000 yr is reported for a sediment core from the subtropical Atlantic continental margin. Maxima in the chlorin accumulation rate coincide with peaks in the accumulation rates of biogenic opal (at the end of glacial periods, and of organic C between those periods). Chlorins, unlike other proxies, may serve as a measure of total primary productivity variations.
