Metabarcoding of Feces of Pacific Walruses and Autosomal DNA Sequence Data of Marine Invertebrates, 2012-2015, Alaska

This data set describes nucleotide sequence data derived from 18S ribosomal DNA amplified in two fragments. A total of 87 feces from Pacific walrus and 57 marine invertebrates were examined for this study. Samples were collected from the Bering Sea and Chukchi Sea, Alaska. Samples used in the study originated from feces or muscle samples collected in the field from ice floes or benthic van Veen grab samples.

本数据集涵盖的核苷酸序列数据，源自经扩增为两个片段的18S核糖体DNA（18S ribosomal DNA）。本研究共检测了87份太平洋海象粪便样本与57份海洋无脊椎动物样本。样本采集自美国阿拉斯加州的白令海与楚科奇海。本研究使用的样本来源包括：野外采集自浮冰的粪便或肌肉组织样本，以及利用底栖范维恩采泥器（van Veen grab）获取的样本。
