TONGA ship campaign November 2019

Emission studies on board the R/V Atalante, Tonga islands

Emission studies will be performed in order to characterize nascent sea spray properties and new particle formation events during the Tonga project (

The specific goals related to Sea2Cloud are:

  • to document the sea spray properties emitted from a subtropical area of the south Pacific Ocean, and how hydrothermal sources present in the Tonga area impact the biogeochemical properties of the seawater and subsequently emission of sea spray.
  • to document the occurrence of new particle formation in the background marine atmosphere of the subtropical South Pacific Ocean, and the impact of airborne volcanic emissions on these occurrence.
