- Description:
-
The project will deliver a comprehensive, high-resolution survey of cloud, precipitation, and aerosol processes along a rare full transect of the southern Pacific Ocean, spanning the tropics to Antarctic waters. By integrating highly detailed continuous gas and aerosol measurements with vertically resolved remote sensing as well as daily aerosol filter sampling and radiosonde deployment, it will provide an invaluable dataset for assessing aerosol–cloud interactions. Building on the previous winter campaign (IN2016_V03), the voyage enables direct evaluation of seasonal contrasts associated with enhanced springtime biological activity. Furthermore, the broader P-TROPOE program synergises and strengthens the investigation, adding concurrent hydrochemical and biological measurements to support a systems level understanding of ocean–atmosphere interactions.
By addressing some of the largest remaining uncertainties in marine cloud and precipitation processes, this project will improve projections of storms and extreme rainfall in the tropics while enhancing our ability to anticipate Antarctica's accelerating response to climate change.

The voyage will undertake multidisciplinary, full-depth physical, biogeochemical, and biological measurements to identify and quantify the key processes driving changes in the ocean’s environmental properties and biological systems; provide new insights into the interactive relationships that exist among physical, biogeochemical, and biological environments from pole to equator and surface to deep ocean, including the identification of potential tipping points and major disruptors; and extend high-precision baseline data sets used to calibrate autonomous observations such as floats, gliders, moorings, and satellites, as well as to improve Earth system models. These data, combined with other observational data and numerical models, will allow for the detection and attribution of ocean change and for more reliable climate predictions and projections. These predictions are used to guide adaptation and mitigation policy, critically needed by Australia and Pacific Island nations. |
