Bulk and clay mineralogy, elemental geochemistry and dinocyst assemblages of sediment core and composite sequence AMD0214-03 the Mackenzie Slope (Beaufort Sea, Canadian Arctic)

Bulk and clay mineralogy and elemental geochemistry, together with dinocyst assemblages, were investigated in order to reconstruct detrital inputs and to estimate sea-surface conditions related to late Holocene ocean-climate variability over the last 2000 years. A box core (BC) (AMD0214-03BC) and a trigger weight core (TWC) and piston core (PC) (AMD0214-03PC) were recovered from the Mackenzie Slope (Beaufort Sea, Canadian Arctic) and combined into a composite sequence (AMD0214-03CS).

本研究对大量沉积物矿物学及粘土矿物学，以及元素地球化学进行了深入分析，旨在重建碎屑输入并估算与过去2000年晚全新世海洋气候变率相关的海表条件。通过对麦克enzie斜坡（波弗特海，加拿大北极地区）采集的箱式岩芯（BC）编号AMD0214-03BC、触发重量岩芯（TWC）和活塞岩芯（PC）编号AMD0214-03PC进行综合，构建了一个复合序列（AMD0214-03CS）。
