Abstract

The Southern Ocean has a profound impact on the Earth's climate system. Its strong winds, intense currents, and fierce waves are critical components of the air-sea interface and contribute to absorbing, storing, and releasing heat, moisture, gases, and momentum. Owing to its remoteness and harsh environment, this region is significantly undersampled, hampering the validation of prediction models and large-scale observations from satellite sensors. Here, an unprecedented data set of simultaneous observations of winds, surface currents, and ocean waves is presented, to address the scarcity of in situ observations in the region-<a hrefCombining double low line"https://doi.org/10.26179/5ed0a30aaf764">https://doi.org/10.26179/5ed0a30aaf764</a> <span classCombining double low line"cit" idCombining double low line"xref_paren.1">(<a hrefCombining double low line"#bib1.bibx6">Alberello et al.</a>, <a hrefCombining double low line"#bib1.bibx6">2020</a><a hrefCombining double low line"#bib1.bibx6">c</a>)</span> and <a hrefCombining double low line"https://doi.org/10.26179/5e9d038c396f2">https://doi.org/10.26179/5e9d038c396f2</a> <span classCombining double low line"cit" idCombining double low line"xref_paren.2">(<a hrefCombining double low line"#bib1.bibx15">Derkani et al.</a>, <a hrefCombining double low line"#bib1.bibx15">2020</a>)</span>. Records were acquired underway during the Antarctic Circumnavigation Expedition (ACE), which went around the Southern Ocean from December 2016 to March 2017 (Austral summer). Observations were obtained with the wave and surface current monitoring system WaMoS-II, which scanned the ocean surface around the vessel using marine radars. Measurements were assessed for quality control and compared against available satellite observations. The data set is the most extensive and comprehensive collection of observations of surface processes for the Southern Ocean and is intended to underpin improvements of wave prediction models around Antarctica and research of air-sea interaction processes, including gas exchange and dynamics of sea spray aerosol particles. The data set has further potentials to support theoretical and numerical research on lower atmosphere, air-sea interface, and upper-ocean processes. .
