CONTRIBUTOR: Julie A. Kennedy, Stanford University IGBP PAGES/WDCA CONTRIBUTION SERIES NUMBER: 96-015 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. ORIGINAL REFERENCE: Kennedy, J.A. and S.C. Brassell, 1992.
