Despite significant differences in collection depth and growth rates, both coral and sclerosponge faithfully recorded the interannual changes of sea surface salinity (SSS) driven by the strong influence of the El Nino Southern Oscillation (ENSO). The strong relationship of coral skeletal d18O with SSS, but not sea surface temperature or precipitation, confirms previous findings that changes in Palau regional surface water are driven by the advection of water masses into the area over interannual timescales associated with ENSO. Opportunities exist for the expansion of short coral proxy records with longer sclerosponge records to verify the stability of ENSO-induced SSS variability over longer timescales. # #--------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: OCE-0426022 and OCE-0610487 #--------------------- # Site_Information # Site_Name: Short Drop Off Reef # Location: Western Pacific Ocean > Republic of Palau # Northernmost_Latitude: 7.266667 # Southernmost_Latitude: 7.266667 # Easternmost_Longitude: 134.516667 # Westernmost_Longitude: 134.516667 # Elevation: -2 to -3 m #------------------ # Data_Collection # Core_Name: Palau H4 Wu2010 # Oldest_Year: 1995 # Most_Recent_Year: 2003 # Time_Unit: AD # Core_Length: # Notes: #------------------ # Chronology # #------------------ # Variables # # Data line variables format: Variables list, one per line, shortname-tab-9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) ## year_AD year,,,AD,,,,,N ## d18Op.lob delta 18O,Porites lobata,,per mil VPDB ,,Corals and Sclerosponges,,,N #----------------- # Data # Missing Value -999 year_AD d18Op.lob 2003.58 -5.732 2003.5 -5.547 2003.42 -5.555 2003.33 -5.402 2003.25 -5.422 2003.17 -5.498 2003.08 -5.482 2003 -5.623 2002.92 -5.622 2002.83 -5.834 2002.75 -5.785 2002.67 -5.805 2002.58 -5.748 2002.5 -5.618 2002.42 -5.708 2002.33 -5.782 2002.25 -5.674 2002.17 -5.604 2002.08 -5.639 2002 -5.603 2001.92 -5.684 2001.83 -5.769 2001.75 -5.803 2001.67 -5.828 2001.58 -5.782 2001.5 -5.858 2001.42 -5.834 2001.33 -5.843 2001.25 -5.741 2001.17 -5.689 2001.08 -5.697 2001 -5.836 2000.92 -5.827 2000.83 -5.799 2000.75 -5.825 2000.67 -5.777 2000.58 -5.82 2000.5 -5.814 2000.42 -5.672 2000.33 -5.68 2000.25 -5.618 2000.17 -5.666 2000.08 -5.581 2000 -5.732 1999.92 -5.709 1999.83 -5.765 1999.75 -5.707 1999.67 -5.653 1999.58 -5.77 1999.5 -5.661 1999.42 -5.65 1999.33 -5.489 1999.25 -5.487 1999.17 -5.528 1999.08 -5.523 1999 -5.539 1998.92 -5.623 1998.83 -5.632 1998.75 -5.545 1998.67 -5.634 1998.58 -5.592 1998.5 -5.585 1998.42 -5.469 1998.33 -5.359 1998.25 -5.334 1998.17 -5.26 1998.08 -5.315 1998 -5.193 1997.92 -5.408 1997.83 -5.394 1997.75 -5.351 1997.67 -5.477 1997.58 -5.462 1997.5 -5.469 1997.42 -5.449 1997.33 -5.35 1997.25 -5.396 1997.17 -5.399 1997.08 -5.377 1997 -5.35 1996.92 -5.414 1996.83 -5.477 1996.75 -5.512 1996.67 -5.547 1996.58 -5.586 1996.5 -5.625 1996.42 -5.614 1996.33 -5.603 1996.25 -5.506 1996.17 -5.41 1996.08 -5.365 1996 -5.319 1995.92 -5.41 1995.83 -5.624 1995.75 -5.737 1995.67 -5.694 1995.58 -5.715
