Summary: This ESH award will support further development and application of the use of marine molluses to reconstruct annually-resolved estimates of water temperature. Four directions are planned: (1) evaluation of amino-acid dating method by comparison with 14C dates, to address varying reservoir age, (2) construct an annual record of 18O for the interval 1600-1880 Ad using cross-matching of growth bands from dated specimens, (3) assess ontogenetic effects on 18O by comparing the same time interval in specimens of different age and (4) explore utility of Mg/Ca and Sr/Ca to resolve temperature and salinity effects upon the oxygen record.

摘要：该 ESH 奖项将支持进一步开发和应用海洋软体动物来重建每年解析的水温估计值。 计划四个方向：（1）通过与 14C 日期比较来评估氨基酸测年方法，以解决不同的储存年龄，（2）利用已测年样本的生长带交叉匹配构建 1600-1880 Ad 区间的 18O 年记录，（3）通过比较不同年龄样本的相同时间间隔来评估 18O 的个体发生效应，（4）探索 Mg/Ca 的效用 和 Sr/Ca 来解决温度和盐度对氧气记录的影响。
