Partial pressure (or fugacity) of carbon dioxide, water temperature, salinity and other variables collected from surface underway observations during the SA Agulhas II SANAE cruise in the Southern and South Atlantic Oceans from 2020-12-26 to 2021-03-04 (NCEI Accession 0287337)

This dataset includes surface underway, chemical, meteorological and physical data collected from SA Agulhas II SANAE cruise in the Southern and South Atlantic Oceans from 2020-12-26 to 2021-03-04. These data include Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water water temperature, salinity and barometric pressure. The Goodhope line between Cape Town, South and SANAE in Antarctica has been continuous sampled every summer (Dec-Feb) since 2008 from the SA Agulhas I (from 2008 to 2011) and SA Agulhas II since 2012. The purpose is to contribute to the global SOCAT quality controlled and gridded dataset is then used for the reconstructions of the CO2 flux in the Southern Ocean. This will continue at least annually in summer, occasional winter and spring lines.

这个数据集包含2020年12月26日至2021年3月4日期间，“SA Agulhas II”号科考船执行SANAE航次时在南大洋及南大西洋收集的表层走航数据、化学数据、气象数据与物理数据。这些数据涵盖大气中二氧化碳分压（或逸度，fugacity）、水中二氧化碳分压（或逸度）、水温、盐度及气压。自2008年起，每年夏季（12月-2月）都会对南非开普敦至南极SANAE站之间的“好望角航线”（Goodhope line）进行连续采样——2008至2011年使用“SA Agulhas I”号，2012年起改用“SA Agulhas II”号。其目的是为全球SOCAT质控网格化数据集提供数据支持，该数据集随后用于南大洋二氧化碳通量的重建。此项采样工作将至少保持每年夏季一次，并偶尔开展冬季及春季航线采样。
