An assessment of the Sr/Ca ratio in shallow water hermatypic corals as a proxy for sea surface temperature

Latitude and longitude inferred for reef from 'Reefs and shoals – Queensland' geodatabase. Coral head collected from site near entrance of prominent gutter at northeastern end of reef. Growing at a depth of 8 m.

Not stated in thesis. Age model created for archiving by tying SrCa maxima to winter minima (July 15) based on HadISST average climatology for Myrmidon Reef.

Multiple U-Th dates from Marshall 2000; top of core age was 7968 ± 100 years and basal core age was 7646 ± 60 years. Minimal information about U-series dating; dates not converted to standard reference time. New U-Th date on alternate slice measured July 2022 and assumed to match youngest year of the record. See GBRCD Appendices.

Ledge sampled every 0.25 mm. Every second sample analysed generally, but consecutive samples analysed around peaks and troughs.
