Duffy and Imbrie's SPECMAP Ocean Cores with 400,000 years BP

Atlantic Ocean core data, about 400K years, SPECMAP. This archive gives Paleoclimate data for a selection of Atlantic cores. It has oxygen-18 data for about 16 cores covering about 400,000 years. Age models for the cores are given. Derived sea surface temperature estimates for 15 cores are given. Delta 13-C data is available for selected cores. Planktic foraminifera counts and factor loadings are given for the cores. Another file includes solar orbital data. This is SPECMAP archive No. 1, 28 Mar 1989.

大西洋洋底核心数据，时间跨度约为40万年，SPECMAP数据集。本档案提供了大西洋核心样本的古气候数据。包含约16个核心样本的氧-18数据，覆盖约40万年。提供了核心样本的年龄模型。对于15个核心样本，给出了衍生海面温度估计值。选定的核心样本提供了碳-13的Δ值数据。同时提供了浮游有孔虫数量和因子负荷数据。另一个文件包含了太阳轨道数据。此为SPECMAP档案编号1，1989年3月28日。
