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 H2 Wu2010 # Oldest_Year: 1993 # 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 -5.393 2003.5 -5.368 2003.42 -5.278 2003.33 -5.231 2003.25 -5.229 2003.17 -5.322 2003.08 -5.381 2003 -5.405 2002.92 -5.511 2002.83 -5.524 2002.75 -5.594 2002.67 -5.64 2002.58 -5.567 2002.5 -5.497 2002.42 -5.617 2002.33 -5.646 2002.25 -5.661 2002.17 -5.788 2002.08 -5.699 2002 -5.68 2001.92 -5.715 2001.83 -5.75 2001.75 -5.69 2001.67 -5.63 2001.58 -5.653 2001.5 -5.677 2001.42 -5.631 2001.33 -5.586 2001.25 -5.58 2001.17 -5.574 2001.08 -5.575 2001 -5.577 2000.92 -5.778 2000.83 -5.818 2000.75 -5.674 2000.67 -5.689 2000.58 -5.747 2000.5 -5.797 2000.42 -5.717 2000.33 -5.604 2000.25 -5.684 2000.17 -5.659 2000.08 -5.637 2000 -5.712 1999.92 -5.804 1999.83 -5.864 1999.75 -5.844 1999.67 -5.809 1999.58 -5.761 1999.5 -5.779 1999.42 -5.784 1999.33 -5.657 1999.25 -5.583 1999.17 -5.582 1999.08 -5.573 1999 -5.562 1998.92 -5.729 1998.83 -5.863 1998.75 -5.613 1998.67 -5.555 1998.58 -5.566 1998.5 -5.508 1998.42 -5.461 1998.33 -5.51 1998.25 -5.437 1998.17 -5.322 1998.08 -5.346 1998 -5.336 1997.92 -5.407 1997.83 -5.503 1997.75 -5.489 1997.67 -5.451 1997.58 -5.477 1997.5 -5.438 1997.42 -5.474 1997.33 -5.529 1997.25 -5.514 1997.17 -5.523 1997.08 -5.611 1997 -5.569 1996.92 -5.717 1996.83 -5.841 1996.75 -5.754 1996.67 -5.818 1996.58 -5.904 1996.5 -5.878 1996.42 -5.801 1996.33 -5.777 1996.25 -5.744 1996.17 -5.574 1996.08 -5.588 1996 -5.579 1995.92 -5.76 1995.83 -5.808 1995.75 -5.942 1995.67 -5.785 1995.58 -5.767 1995.5 -5.759 1995.42 -5.664 1995.33 -5.565 1995.25 -5.454 1995.17 -5.45 1995.08 -5.347 1995 -5.464 1994.92 -5.465 1994.83 -5.489 1994.75 -5.676 1994.67 -5.642 1994.58 -5.423 1994.5 -5.498 1994.42 -5.529 1994.33 -5.488 1994.25 -5.364 1994.17 -5.367 1994.08 -5.375 1994 -5.273 1993.92 -5.426 1993.83 -5.519
