Fig. 1: Chlorophyll and SST along with the conducted measurement programme in the equatorial Atlantic.
From: Seasonal productivity of the equatorial Atlantic shaped by distinct wind-driven processes
a–c, Shown are climatological July chlorophyll in the tropical Atlantic (a) and the climatological seasonal cycles along the equator (meridional averaged in the red box, shown in a) of chlorophyll (b) and SST (c). Also included are mooring locations along the equator (a) and in tracks of two trans-Atlantic equatorial cruises (b,c), R/V Meteor cruises M158 from 29 September to 22 October 2019 and M181 from 30 April to 20 May 2022. The open ocean equatorial chlorophyll distribution that is strongly enhanced in the centre of the cold tongue at about 0°, 10° W during boreal summer is the main topic of the present study. Note the enhanced chlorophyll concentrations associated with the outflow of the Amazon and Congo rivers. The maps were created using the Python packages matplotlib (version 3.8.4)48 and basemap (version 1.4.1; https://matplotlib.org/basemap/stable/).
