Scientific sampling event log from the US GEOTRACES GP17-OCE cruise on R/V Roger Revelle (RR2214) from December 2022 to January 2023

This dataset is the scientific sampling event log from the US GEOTRACES GP17-OCE cruise on R/V Roger Revelle (RR2214). The expedition departed Papeete, Tahiti (French Polynesia) on December 1st, 2022 and arrived in Punta Arenas, Chile on January 25th, 2023. The cruise took place in the South Pacific and Southern Oceans aboard the R/V Roger Revelle with a team of 34 scientists led by Ben Twining (Chief Scientist), Jessica Fitzsimmons, and Greg Cutter (Co-Chief Scientists). GP17 was planned as a two-leg expedition, with its first leg (GP17-OCE) as a southward extension of the 2018 GP15 Alaska-Tahiti expedition and a second leg (GP17-ANT; December 2023-January 2024) into coastal and shelf waters of Antarctica's Amundsen Sea.本数据集为美国全球海洋示踪物计划（GEOTRACES）GP17-OCE航次（搭载平台为“罗杰·雷维尔号（R/V Roger Revelle）”，航次编号RR2214）的科学采样事件日志。本次航次于2022年12月1日从法属波利尼西亚塔希提岛帕皮提港起航，2023年1月25日抵达智利蓬塔阿雷纳斯港，作业海域覆盖南太平洋与南大洋。科考团队共计34人，由首席科学家本·特怀宁（Ben Twining）、联合首席科学家杰西卡·菲茨西蒙斯（Jessica Fitzsimmons）与格雷格·卡特勒（Greg Cutter）领衔执行任务。GP17航次原规划为两段式科考任务：其第一段航次（GP17-OCE）为2018年GP15阿拉斯加-塔希提航次的南向延伸作业段；第二段航次（GP17-ANT；2023年12月—2024年1月）则前往南极洲阿蒙森海的近岸与陆架海域开展科考作业。
