Fig. S2. Monthly average CHL for 2002-2016 in the south-eastern Gulf and north-western Gulf of Oman area between A. November and L. October. White stars are Socotra cormorant colonies with >27 000 breeding pairs. From west to east are the colonies of Zakhnuniyah and Judhaym Islands (Saudia Arabia), Suwad al Janubiyah Island (Hawar Islands group, Bahrain) and Siniya Island (UAE). Black pixels correspond to absence of data due to cloud cover.
