Oceanographic changes adjacent to Antarctica have global climatic and ecological impacts. However, this is the most challenging place in the world to obtain marine data due to its remoteness and inhospitable nature, especially in winter. Here, we present more than 2000 Conductivity-Temperature-Depth (CTD) profiles and associated water sample data collected with (almost uniquely) full year-round coverage from the British Antarctic Survey Rothera Research Station at the west Antarctic Peninsula. Sampling is conducted from a small boat or a sled, depending on the sea ice conditions. When conditions allow, sampling is twice weekly in summer and weekly in winter, with profiling to nominally 500 m and with discrete water samples taken at 15 m water depth. Daily observations are made of the sea ice conditions in the area. This paper presents the first 20 years of data collection, 1997-2017. This time series represents a unique and valuable resource for investigations of the high-latitude ocean's role in climate change, ocean/ice interactions, and marine biogeochemistry and carbon drawdown.
毗邻南极洲的海洋变化对全球气候和生态都有影响。然而，由于其偏远和恶劣的自然环境，特别是在冬季，这里是世界上获取海洋数据最具挑战性的地方。在这里，我们展示了英国南极调查罗瑟拉研究站在西南极半岛收集的超过 2000 条 CTD 剖面和相关的水样数据，这些数据几乎全年都有（几乎独一无二）的覆盖。采样是根据海冰条件从小船或雪橇上进行的。在条件允许的情况下，夏季每两周采样一次，冬季每周采样一次，剖面深度名义上为 500 米，每隔 15 米采集离散水样。每天对该地区的海冰状况进行观测。本文介绍了 1997 年至 2017 年的前 20 年的数据收集情况。这一时间序列是研究高纬度海洋在气候变化、海洋/冰相互作用以及海洋生物地球化学和碳减排中的作用的独特而有价值的资源。
