Major inorganic ions in Primary Marine Aerosols (PMA) generated from seawater collected near the BATS station during R/V Atlantic Explorer cruises AE2113 (July 2021) and AE2303 (January 2023)

This dataset includes the concentrations of seven major inorganic ions determined in primary marine aerosol (PMA) samples collected from the Bermuda Atlantic Time-series Study (BATS) station during a summer cruise in 2021 and a winter cruise in 2023 aboard the R/V Atlantic Explorer. The major ions in PMA samples were collected using a high-capacity aerosol generator and the major ions were quantified using a Dionex dual channel model ICS 6000 high-performance ion chromatograph (ICS-6000 DP). This dataset was generated and prepared by Dr. Lei Xue under the supervision of Dr. David Kieber at the State University of New York, College of Environmental Science and Forestry. These data were used to determine the enrichment of major ions in PMA samples and to calculate the enrichment factors of protein/peptides and carbohydrates in PMA samples relative to bulk seawater and the associated seasonal variability. This work is part of a larger study to understand the seasonal variability in the fraction of refractory organic carbon in primary marine aerosol at the BATS station.本数据集包含2021年夏季航次与2023年冬季航次期间，在百慕大大西洋时间序列研究（Bermuda Atlantic Time-series Study, BATS）站位采集的原生海洋气溶胶（Primary Marine Aerosol, PMA）样品中测定的7种主要无机离子浓度，两次航次均由R/V Atlantic Explorer号研究船执行。PMA样品中的主要无机离子通过大容量气溶胶发生器完成采集，并采用戴安（Dionex）双通道ICS 6000型高性能离子色谱仪（ICS-6000 DP）完成定量分析。本数据集由纽约州立大学环境科学与林业学院的大卫·基伯（David Kieber）博士指导下的雷雪博士编制生成。该数据集被用于分析PMA样品中主要无机离子的富集特征，并计算相较于主体海水（bulk seawater）的PMA样品中蛋白质/多肽与碳水化合物的富集因子，以及相关的季节变化规律。本研究为一项更大尺度研究的组成部分，该研究旨在阐明BATS站位处原生海洋气溶胶中难降解有机碳占比的季节变化特征。
