New research reveals that dust carried by the wind from southern Africa towards Madagascar triggered the largest phytoplankton bloom in two decades – and, unusually, this occurred at a time of year when such blooms are rarely seen. The animation shows the extent of this bloom between November 2019 and January 2020. While the relationship between desertification, dust emissions, and ocean fertilisation remains poorly understood, a new paper published in PNAS Nexus marks a significant step in unravelling these connections.
