Dataset on the content of chemical elements in the bottom sediments and bivalve mollusks of the Kara Sea

The dataset includes the content of 65 chemical elements in soft tissues and shells of five species of bivalve mollusks (Astarte crenata, Ciliatocardium ciliatum, Portlandia arctica, Chlamys islandica, Hiatella arctica), as well as in the upper layer (0-5 cm) of bottom sediments of the Kara Sea, the Arctic Ocean. The content of major-, trace and rare-earth elements was determined by atomic emission and inductively coupled plasma mass spectrometry (ICP-AES; ICP-MS). The age, size, and weight of mollusks were also presented.

本数据集收录了五种双壳软体动物（Astarte crenata、Ciliatocardium ciliatum、Portlandia arctica、Chlamys islandica、Hiatella arctica）的软组织和贝壳中65种化学元素的含量，以及北极海洋卡拉海海底沉积物上层（0-5厘米）的化学元素含量。主要元素、微量元素和稀土元素的含量通过原子发射光谱和电感耦合等离子体质谱法（ICP-AES；ICP-MS）测定。此外，还提供了软体动物的时代、尺寸和重量信息。
