Abstract:
Elevated productivity in the northwest Pacific is suggested as a new possible control driving past intervals of low-O (sub 2) intermediate water along the western continental margin of North America. According to this mechanism, O (sub 2) consumption would occur near the site of formation of North Pacific Intermediate Water (NPIW), due to increased respiration of organic carbon in response to a high-productivity event. Evidence is provided for such a productivity increase during the Bolling-Allerod interval (14.7-12.9 ka), a time when laminated sediments were deposited along the northern California margin. By this mechanism, low-O (sub 2) events in intermediate waters off the western North American margin could occur without significant changes in the rate of NPIW ventilation.
