From: Response of Red Sea phytoplankton biomass to marine heatwaves and cold-spells

Decadal trends of the total number of MHW and MCS days during the main phytoplankton growth period (October-March) in the Red Sea, based on satellite-derived data (reprocessed OSTIA) between 1982–2018. (a) Trend of MHW days/decade. The horizontal grey lines divide the Red Sea into four distinct regions: Northern Red Sea (NRS), North Central Red Sea (NCRS), South Central Red Sea (SCRS), and Southern Red Sea (SRS). (b) Trend of MCS days/decade.
