Description:
Seawater oxygen isotope ratios (𝛅¹⁸O_sw) provide powerful constraints on ocean circulation and ocean-atmosphere exchange processes. Observational 𝛅¹⁸O_sw data provide important information on the modern ocean and global water cycle and are an increasingly critical diagnostic tool for isotope-enabled climate models. They are also essential for the accurate calibration of 𝛅¹⁸O-based hydrological reconstructions from paleo-oceanographic archives. A growing number of new 𝛅¹⁸O_sw datasets have been published during the last two decades, however, the lack of a centralized, actively-curated public data repository targeted to these data has limited their discoverability and inclusion in new studies. Over the past year, the PAGES CoralHydro2k project has collected a number of these ‘hidden’ 𝛅¹⁸O_sw datasets to aid in our investigation of tropical hydroclimate variability and change using paired coral 𝛅¹⁸O and Sr/Ca records. In recognition of the value of 𝛅¹⁸O_sw data to the broader ocean and climate science communities, we have collated these records into a new, machine-readable, and metadata-rich database consistent with FAIR data standards. Here, we present a summary of our crowdsourcing efforts and a description of the database, including over 3000 globally-distributed measurements of 𝛅¹⁸O_sw, to date. We welcome direct data submissions and/or recommendations for inclusion of published datasets via our online survey: https://fsu.qualtrics.com/jfe/form/SV_094ofPIJKM5KNyC.
