Abstract. As our planet warms, Arctic sea ice coverage continues to decline resulting in complex feedbacks with the climate system. The core objective of NASA’s Salinity and Stratification at the Sea Ice Edge (SASSIE) mission is to understand how ocean salinity and near-surface stratification affect upper ocean heat content, and thus sea ice freeze and melt. SASSIE specifically focuses on the formation of Arctic sea ice in autumn. The SASSIE field campaign in 2022 collected detailed observations of upper ocean properties and meteorology near the sea ice edge in the Beaufort Sea using ship-based and piloted and drifting assets. The observations collected during SASSIE include vertical profiles of stratification up to the sea surface, air-sea fluxes, and ancillary measurements that are being used to better understand the role of salinity in coupled Arctic air-sea-ice processes. This publication provides a detailed overview of the activities during the 2022 SASSIE campaign and presents the publicly available datasets generated by this mission, inducing an accompanying repository that highlights the numerical routines used to generate the figures shown in this manuscript.

Short summary
The NASA SASSIE mission aims to understand the role of salinity in modifying sea ice formation in early autumn. The 2022 SASSIE campaign collected measurements of upper ocean properties including stratification (layering of the ocean) and air-sea fluxes in the Beaufort Sea. These data are presented here and made publicly available on the NASA Physical Oceanography Distributed Active Archive Center (PO.DAAC) along with code to manipulate the data and generate the figures presented herein.
