SAIL - Space-Atmosphere-Ocean Interactions in the marine boundary Layer

SAIL (Space-Atmosphere-Ocean Interactions in the marine boundary Layer) aims to improve the scientific understanding of the marine boundary layer by means of an unique monitoring campaign on board the ship-rigged sailing ship NRP Sagres during its 2020 circumnavigation expedition. The campaign will enable the measurement of the atmospheric electric field over the global oceans, and to study space-driven interactions via the detailed monitoring of GNSS signals, cosmic radiation, environmental radioactivity and atmospheric ionization. The atmospheric measurements will be complemented by the collection of biological indicators of ocean's health, and underwater monitoring of the ocean state (temperature, conductivity, dissolved oxygen, pH, spectral radiance) for a detailed study of ocean-atmosphere fluxes and surface-atmosphere interactions.
