Tropical ocean hydroclimate and temperature from coral archives

doi:10.22498/pages.28.1.29

Abstract

Highlights

The CoralHydro2k project of the PAGES 2k Network met at the University of New South Wales before the 13th International Conference on Paleoceanography in Sydney, Australia, for our first in-person meeting
The goal of CoralHydro2k is to build upon Ocean2k temperature reconstructions (Tierney et al 2015) by using new and existing coral-based reconstructions to examine temperature and salinity changes through paired records of coral strontium to calcium (Sr/Ca) and oxygen isotopic ratios (δ18O; e.g. Felis et al 2018)
One aim of CoralHydro2k is the generation and inclusion of new paired coral Sr/Ca and δ18O records that allow for investigations of seasonal-to-multidecadal variability of hydroclimate

Summary

Introduction

The CoralHydro2k project of the PAGES 2k Network met at the University of New South Wales before the 13th International Conference on Paleoceanography in Sydney, Australia, for our first in-person meeting (pastglobalchanges.org/calendar/2019/127pages/1744). The goal of CoralHydro2k is to build upon Ocean2k temperature reconstructions (Tierney et al 2015) by using new and existing coral-based reconstructions to examine temperature and salinity changes (i.e. hydroclimate) through paired records of coral strontium to calcium (Sr/Ca) and oxygen isotopic ratios (δ18O; e.g. Felis et al 2018). The workshop started with a review of the aims of the project followed by updates of current temperature and salinity reconstructions, and concluded with further discussions about the best practices for coral-based reconstructions.
