(a) Mean climatological surface chlorophyll-a (Chla) concentration (mg m−3) in the NW Mediterranean (see text for definition) from MODIS data (2003–2015). (b) Mean surface Chla (mg m−3) spatial distribution for the blooming period (vertical bars in panel a) from MODIS data (2003–2015). Maps were created by the authors using MATLAB software vR2014b (https://it.mathworks.com/products/matlab/matlab-graphics.html).
