Geochemical analysis of authigenic carbonates and chemosynthetic mussels at Atlantic Margin seeps

Isotopic analyses of authigenic carbonates and methanotrophic deep-sea mussels, Bathymodiolus sp., was performed on samples collected from seep fields in the Baltimore and Norfolk Canyons on the north Atlantic margin. Samples were collected using remotely operated underwater vehicles (ROVs) during three different research cruises in 2012, 2013, and 2015. Analyses were performed by several different laboratories, and the results are presented in spreadsheet format.

本数据集对采集自北大西洋边缘巴尔的摩峡谷与诺福克峡谷冷泉场的样品开展了同位素分析，分析对象包括自生碳酸盐岩与甲烷氧化型深海贻贝——偏顶蛤属（Bathymodiolus）未定种。所有样品系2012、2013及2015年三次考察航次中，通过遥控水下机器人（Remotely Operated Underwater Vehicles, ROVs）采集获得。本次分析由多家不同实验室完成，最终结果以电子表格格式呈现。
