Atmosphere-driven compound extremes: record marine heatwave and phytoplankton bloom in the Ross Sea during summer 2022–2023
We document an extreme marine heatwave (MHW) in the eastern Ross Sea during the 2022–2023 austral summer (DJF), the most intense thermal event in the satellite record. Using satellite-retrieved sea surface temperature (SST), ocean colour, sea ice, and atmospheric-oceanic reanalysis data, we show that the eastern Ross S...
