Seasonal suitable habitat index of mesozooplankton in the North Atlantic for (a) April–September and (b) October–March 2003–2017. The suitable habitat index is defined by the presence of large productivity fronts and is expressed as the frequency of occurrence weighted by the front size. Blank areas denote habitat coverage below 1% of the total number of days in the considered time period, except the Baltic Sea, which was not considered (see text).
