Tang, Weiyi; Llort, Joan; Weis, Jakob; Perron, Morgane M. G.; Basart, Sara; Li, Zuchuan et al. (2021): Widespread phytoplankton blooms triggered by 2019-2020 Australian wildfires. In Nature 597 (7876), pp. 370–375. DOI: 10.1038/s41586-021-03805-8.

„Droughts and climate-change-driven warming are leading to more frequent and intense wildfires1,2,3, arguably contributing to the severe 2019–2020 Australian wildfires4. The environmental and ecological impacts of the fires include loss of habitats and the emission of substantial amounts of atmospheric aerosols5,6,7. Aerosol emissions from wildfires can lead to the atmospheric transport of macronutrients and bio-essential trace metals such as nitrogen and iron, respectively8,9,10. It has been suggested that the oceanic deposition of wildfire aerosols can relieve nutrient limitations and, consequently, enhance marine productivity11,12, but direct observations are lacking. Here we use satellite and autonomous biogeochemical Argo float data to evaluate the effect of 2019–2020 Australian wildfire aerosol deposition on phytoplankton productivity.“
