SASSIE Arctic Field Campaign Shipboard Salinity Snake Data Fall 2022

The Salinity and Stratification at the Sea Ice Edge (SASSIE) project is a NASA experiment that aims to understand how salinity anomalies in the upper ocean generated by melting sea ice affect sea surface temperature (SST), stratification, and subsequent sea-ice growth. SASSIE involved a field campaign that sampled the transition from summer melt to autumn ice advance in the Beaufort Sea during August-October 2022, making intensive in situ and remote sensing observations within ~200km of the sea ice edge. This dataset contains salinity and temperature measurements collected by a shipboard salinity snake. The salinity snake system consisted of a ship-mounted boom with a length of 10m to provide sampling of undisturbed water at a depth of 1-2cm. Salinity data are delayed by 40s, which is the average residence time in the hose, pump, and shipboard system before being analyzed. Data are available in netCDF format.

海冰边缘盐度与层化项目（Salinity and Stratification at the Sea Ice Edge，简称SASSIE）是美国国家航空航天局（NASA）发起的一项实验，旨在探究海冰融化产生的上层海洋盐度异常如何影响海表温度（SST）、水体层化以及后续的海冰生长过程。SASSIE项目于2022年8月至10月在波弗特海开展野外科考作业，对夏季融冰至秋季海冰推进的过渡阶段进行采样，并在海冰边缘约200公里范围内开展了高密度原位与遥感观测。本数据集包含船载盐度蛇（shipboard salinity snake）采集的盐度与温度测量数据。该盐度蛇系统由一套安装在船舷的10米长吊杆组成，可在1至2厘米深度处采集未受扰动的水体样本。盐度数据存在40秒的延迟，该时长为数据在管路、泵组及船载系统中完成传输与分析前的平均停留时间。数据以netCDF格式提供。
