4. Modelling predicts dust deposition in different parts of the Southern Ocean. In nature today, we combine 11 years of NO₃ measurements from 252 floats with our dust predictions. SO phytoplankton growth increases as iron-rich dust supply increases. rdcu.be/dH3XH

In new work, my colleagues show one-third of Southern Ocean biological activity is supported by dust landing there. Two-thirds at the last glacial maximum when there was more dust landing. Wow.

A tale of robots, dust and life in the Southern Ocean Intrigued? Have a look at our nature paper to see how we used a fleet of @bgc_argo profiling floats to calculate how much iron derived from windblown mineral dust contributes to 🌊 Southern Ocean productivity. 🌬️🏜️🌊🌱

Iron-rich dust feeds phytoplankton. They are a key form of life in the Southern Ocean, which acts as a climate shock absorber, explains experts from University of Tasmania. theconversation.com/floating-robot…

NEW STUDY: w/ ACEAS co-author Zanna Chase shows windblown dust fuels a third of phytoplankton growth in the Southern Ocean. Drier + windier land conditions in future could impact future ocean ecosystems & fisheries. STORY: antarctic.org.au/windblown-dust… PAPER: nature.com/articles/s4158…

Scientists from IMAS, CSIRO, ARC Centre of Excellence for Climate Extremes, Australian Centre for Antarctic Science (ACEAS) & AAPP use robotic floats to find dust from land fertilises 🅞🅝🅔-🅣🅗🅘🅡🅓 of the Southern Ocean’s productivity — revealing the key role of dust in carbon storage and global climate. aappartnership.org.au/windblown-dust…

On that note: Future maintenance, let alone expansion, of the @bgc_argo array is far from secured. Funding is dwindling. This is a real shame, given how immensely valuable these observations are for understanding ocean ecosystems at the basin-scale!

A new IMAS-led study using robotic floats has revealed just how much airborne dust fertilises the Southern Ocean - which is a key climate 'shock absorber'. Find out why this is critical for the Earth's climate: tinyurl.com/mrj3zyhv

New paper published in Nature! Using a fleet of ocean robots, Jake Weis and his co-authors have discovered that windblown dust from land delivers enough iron to support a third of the Southern Ocean’s phytoplankton growth. Read more here: nature.com/articles/s4158…

Phytoplankton feeds us, but what's feeding the phytoplankton? 🍽️ We were recently part of a team led by University of Tasmania that used robotic floats to discover that windblown dust delivers enough iron to support a third of the Southern Ocean’s phytoplankton growth. csiro.au/en/news/All/Ar…
