Fig. 2From: Evaluation of geochemical records as a paleoenvironmental proxy in the hypercalcified demosponge Astrosclera willeyanaMonthly mean climatology and logging data of seawater temperature and salinity at the study site. Data are derived from the Japan Oceanographic Data Center (JODC) for 1906–2003 (26°–27° N, 126°–127° E; http://www.jodc.go.jp/) and in situ observations made during October 2015 to November 2016 using loggers in this study. Error bars represent monthly maximum and minimum values in the past. Salinity of seawater samples collected at the site was also measured for cross-validationBack to article page
