NAME OF DATA SET: Santa Barbara basin alkenones
LAST UPDATE: 7/96 (Original receipt date by NOAA/ WDC-A Paleo)
GEOGRAPHIC REGION: Santa Barbara basin, coastal California, 34 14'N, 120 01'W
PERIOD OF RECORD: 1915-1988 A.D.
DESCRIPTION:
Annual variations in alkenone unsaturation in laminated sediments
in the Santa Barbara basin reveal increases in water temperature
which can be linked directly to the observed sequence of El Nino
events in the twentieth century. Water temperatures calculated
from Uk37 values correspond broadly to 20m water temperature
data of the calCOFI program for 1953-1984. Full details of
sampling and methodology are in the file methods.txt.

Appendix A.3 Correlation of all Santa Barbara Basin cores based on the accumulated
wet mass overlying a given layer at a given depth. Equivalent sample number from the
various cores are shown. The estimated weight of core-top sediment not recovered for
cores 10a and 10b is 45g.
