Abstract
<p>In order to investigate the properties of coral reef origin secondary organic aerosol, ethanol affinity to atmospheric nucleation mode particles (diameter < 15 nm) was measured at the Heron reef marine environment in the South Pacific Ocean during the first coral reef aerosol characterization experiment in May-June 2011 using an ultrafine organic tandem differential mobility analyser. Our campaign study at Heron reef showed that the nucleation mode size particles (diameter = 10 nm) composition contain internally mixed sulfate and oxidized organic components in approximately equal proportion in sunny and still conditions around low tide time, indicating local biogenic sources. The produced secondary compounds and aerosols have potential to contribute to cloud condensation nuclei formation and properties that may affect<br />local low-level cloud formation over the GBR. Additionally, primary marine sea-salt and organic material during windy conditions and anthropogenic/biogenic sources during continental air masses can affect the properties of these particles.</p>
