| Biogenic opal, organic carbon, organic matter stable isotope, and trace metal data from a well-dated, high-resolution jumbo piston core (EW0408-85JC; 59 degrees 33.3'N, 144 degrees 9.21'W, 682 m water depth) recovered from the northern Gulf of Alaska continental slope reveal changes in productivity and nutrient utilization over the last 17,000 years. Maximum values of opal concentration (similar to 10%) occur during the deglacial Bolling-Allerod (B-A) interval and earliest Holocene (11.2 to 10.8 cal ka BP), moderate values (similar to 6%) occur during the Younger Dryas (13.0 to 11.2 cal ka BP) and Holocene, and minimum values (similar to 3.5%) occur during the Late Glacial Interval (LGI). When converted to opal mass accumulation rates, the highest values... |
