Abstract. Iodine-initiated new particle formation (I-NPF) has long been recognized in coastal hotspot regions. However, no prior work has studied the exact chemical composition of organic compounds and their role in the coastal I-NPF. Here we present an important complementary study to the ongoing laboratory and field researches of iodine nucleation in coastal atmosphere. Oxidation and NPF experiments with vapor emissions from real-world coastal macroalgae were simulated in a bag reactor. On the basis of comprehensive mass spectrometry measurements, we reported for the first time a variety of volatile precursors and their oxidation products in gas and particle phases in such a highly complex system. Organic compounds overwhelmingly dominated over iodine in the new particle growth initiated by iodine species. The identity and transformation mechanisms of organic compounds were proposed in this study to provide a more complete story of coastal NPF from low-tide macroalgal emission.

Short summary
The organic compounds involved in continental new particle formation have been investigated in depth in last two decades. In contrast, no prior work has studied the exact chemical composition of organic compounds and their role in the coastal new particle formation. We present an important complementary study to the ongoing laboratory and field researches of iodine nucleation in coastal atmosphere. This study provided a more complete story of coastal I-NPF from low-tide macroalgal emission.
