Collaborative Research: Refinement of Paleotemperature Records from 0-18 of Arctica Shells for the Last 1000 years

总结：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决的水温估计。 规划了四个方向：（1）通过与~（14）C测年的比较，对氨基酸测年方法进行评价，以确定不同的储层年龄;（2）通过对测年标本的生长带进行交叉匹配，建立公元1600-1880年的~（18）O年记录;（3）通过比较不同年龄标本中相同时间间隔的18 O，评估个体发育效应;（4）探索Mg/Ca和Sr/钙解决温度和盐度对氧记录的影响。

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.
