Sea spray data from the Surface Ocean Aerosol Production (SOAP) study

The Surface Ocean Aerosol Production (SOAP) voyage examined air-sea interactions over the productive waters of the Chatham Rise, east of New Zealand on board the RV Tangaroa (New Zealand National Institute of Water and Atmospheric Research, Wellington) from February 12 to March 7, 2012.

23 seawater samples were collected throughout the voyage for the purpose of generating nascent SSA. The volatility and hygroscopicity of nascent SSA (Sea Spray Aerosol) were determined with a volatility and hygroscopicity tandem differential mobility analyser (VH-TDMA). The VH-TDMA was also used to calculate the organic volume fraction.

Filters were collected for compositional analysis using transmission Fourier Transform Infra-Red (FTIR) and Ion Beam analysis (IBA).

SOAP航次对新西兰东部的查塔姆升高产水域的空气-海相互作用进行了考察，此次考察于2012年2月12日至3月7日由“汤加罗瓦”号（新西兰国家水资源与大气研究所，惠灵顿）进行。在航行过程中共收集了23个海水样本，旨在生成新生成态的悬浮颗粒物（SSA）。新生成态悬浮颗粒物（海雾气溶胶）的挥发性和吸湿性通过挥发性和吸湿性串联差动电离质量分析仪（VH-TDMA）进行测定。VH-TDMA还用于计算有机体积分数。同时收集了用于成分分析的滤纸，通过透射傅里叶变换红外光谱（FTIR）和离子束分析（IBA）进行组成分析。
