Title:
Coral-based Proxy Records of Ocean Acidification: A Pilot Study at the Puerto Rico Test-bed Site
Description:
Abstract:
Coral cores collected nearby the Atlantic Ocean Acidification Test-bed (AOAT) at La Parguera, Puerto Rico were used to characterize the relationship between paleo-variations in coral growth and calcification and seawater pH via the boron isotope proxy. This study addressed impacts of ocean acidification in a geological context to quantify baseline variability in growth and pH and assess the historical response of coral ecosystems to increased atmospheric CO2 and enhance on-going AOAT observations.
Purpose:
Establishing historical baselines in coral growth, calcification, and seawater pH
Supplemental_Information:
Cores currently included in this data set include growth records ranging from 1748 to 2009. The individual growth records currently include cores EFR 1: 2009 – 1900 = 110, EBR 1: 2009 – 2001 = 9 yrs, EBR 2: 2009 – 2000 = 10 yrs, LPT A: 2004 - 1794 = 210 yrs, LPT C: 2004 - 1943 = 61 yrs, LPT E: 2004 - 1939 = 65 yrs, LPT G: 2004 - 1967 = 37 yrs, LPT I: 2004 - 1748 = 256 yrs, LPT H: 2004 - 1918 = 86 yrs, LPP A: 2004-1973 = 32 yrs, LPP B: 2004-1901 = 104 yrs, LPP C: 2004-1825 = 181 yrs, LPP D: 2004-1839 = 166 yrs, LPP I: 2004-1970 = 35 yrs.
