Abstract

Measurements of the age difference between coexisting benthic and planktic foraminifera from western equatorial Pacific deep-sea cores suggest that during peak glacial time the radiocarbon age of water at 2-kilometers depth was no greater than that of today. These results make unlikely suggestions that a slowdown in deep-ocean ventilation was responsible for a sizable fraction of the increase of the ratio of carbon-14 ( 14 C) to carbon in the atmosphere and surface ocean during glacial time. Comparison of 14 C ages for coexisting wood and planktic foraminifera from the same site suggests that the atmosphere to surface ocean 14 C to C ratio difference was not substantially different from today's.

Alex Wiedenhoeft of the Forest Products Laboratory in Madison Wisconsin advised us that it was not possible to identify milligram-sized fragments of tropical woods; rather a hand-sized piece of wood would be required. He also commented that once waterlogged any wood would be dense enough to sink in seawater.
