Online Resource 2.Chlorophyll a concentration (Chla) and primary production (PP) at the sampling sites in 66th cruise RV “AkademikMstislavKeldysh”. Coordinates of the sampling sites are given in Online Resource 1. Values of primary production are given at the depths where samples for Chla determination were taken. The method for calculation of lower boundary of photosynthetic layer was described in Materials and methods section.
