The high-time resolution (∼70 years in average) multi-proxy analysis conducted on the mid-shelf core CBT-CS11 (47°46.429'N; 4°25.308'W; 73 m depth; 3.96 m long; NW France, S Brittany) revealed the complexity of the palaeohydrological and palaeoclimatic signals recorded over the last 7 kyrs in the recently published paper: "Oceanic continental influences over the last 7 kyrs from a midshelf record in the northern Bay of Biscay (NE Atlantic)" [1]. This study presents the whole CBT-CS11 dataset discussed in [1] including sedimentological (XRF and grain-size (total from [1] and CaCO-free from [2]) analyses), geochemical (oxygen and carbon stable isotopes on two different benthic foraminiferal species: from [1] and from [2]) analyses) as well as palynological (dinoflagellate cyst and pollen assemblages from [1]) data. The present study also describes the different statistical tests from which ecological groups have been established from palynological indicators in [1].
在中陆架岩芯CBT-CS11(北纬47°46.429';西经4°25.308';深度73米;长3.96米;法国西北部,布列塔尼南部)上进行的高时间分辨率(平均约70年)多指标分析揭示了最近发表的论文《过去7千年比斯开湾北部(东北大西洋)中陆架记录中的海洋与大陆影响》[1]中所记录的过去7000年古水文和古气候信号的复杂性。本研究展示了[1]中所讨论的整个CBT-CS11数据集,包括沉积学分析(X射线荧光分析和粒度分析([1]中的总量分析以及[2]中的无碳酸钙分析))、地球化学分析(对两种不同底栖有孔虫物种进行氧和碳稳定同位素分析:来自[1]和来自[2])以及孢粉学分析(来自[1]的甲藻孢囊和花粉组合)数据。本研究还描述了[1]中根据孢粉学指标建立生态组所采用的不同统计检验方法。
