Corals were collected from 5 m, 85 m, and 105 m depth. Stable isotopes were measured by combusting each organic skeletal sample in a Costech Elemental Analyzer where the resulting N2 and CO2 gases were analyzed with a Finnigan Delta IV Plus isotope ratio mass spectrometer via a Finnigan ConFlow III open split interface. D15N values were reported relative to air. d13C values were reported relative to Vienna Peedee Belemnite Limestone Standard (VPDB). The standard deviation of the mean of repeated measurements of internal standards was ±0.15 per mil for d15N and ±0.06 for d13C. At least 10% of all samples were run in duplicate. The stable isotope records were depth-corrected according to Williams and Grottoli (GCA, 2010). Growth chronologies for the stable isotope records were developed through identification of the 14C bomb-curve. D14C was measured at the National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) Facility at the Woods Hole Oceanographic Institution using standard NOSAMS methods [Osborne et al., 1994]. Values were reported as D14C (the per mil deviation of 14C/12C of the sample relative to that of 95% Oxalic Acid-1 standard) and were blank corrected. The reported uncertainty of duplicate analyses of a known standard was typically ±5-8 per mil. ABSTRACT SUPPLIED BY ORIGINATOR: Long records of subsurface ocean observations are key to constrain our understanding of the climate response of the tropical Pacific to increasing greenhouse gases. Due to the lack of continuous ocean observations, proxies become essential to estimate changes in the tropical thermocline related to changes in Walker circulation. Here, we present high resolution stable nitrogen (d15N) and carbon (d13C) isotope records from three proteinaceous corals spanning the top 105 m of the euphotic zone from an offshore Palauan reef in the western tropical Pacific. Dated with radiocarbon-derived growth chronologies, these isotope records indicate a shoaling of the mean nutricline and thus the thermocline as well, and a likely increase in primary productivity in the western tropical Pacific since the mid-to-late 1970s. Thus, these are the first subsurface proxy data extending below 20 m to support a slowdown of the tropical Pacific Walker circulation during the 20th Century.
