Sediment chemistry data collected during R/V Atlantis/Alvin (DSV-2) cruise AT26-13 in the northern Gulf of Mexico from 2014-03-31 to 2014-04-01

​​The R/V Atlantis cruise AT26-13 set sail with the HOV Alvin on board on March 30, 2014. The objectives of the cruise were to visit sites impacted by the Macondo Blowout as well as n​atural seeps sites dominated by oil and gas discharge. The science team included biological and chemical oceanographers, geochemists, microbiologists, as well as a tream equipped for remote sensing and documentation of seafloor dynamics using in situ camera systems. The cruise sailed on March 30 and returned April 23. GoMRI funded Alvin dives occurred on March 31st and April 1st of 2014. This dataset includes sediment samples collected on those dives.

2014年3月30日，搭载载人深潜器阿尔文（HOV Alvin）的亚特兰蒂斯号研究船（R/V Atlantis）执行AT26-13航次任务并起航。本次航次的考察目标为两类区域：一是受马孔多井喷事故（Macondo Blowout）影响的海域，二是以油气溢漏为主要特征的天然渗漏点。科考团队由生物海洋学家、化学海洋学家、地球化学家与微生物学家组成，同时配备了可借助原位摄像系统开展遥感作业与海底动力学记录的专业小组。本航次于3月30日出航，4月23日返航。2014年3月31日与4月1日，执行了由墨西哥湾研究计划（GoMRI）资助的阿尔文号下潜作业。本数据集包含上述下潜任务采集的沉积物样品。
