- Аннотация: The vertical distribution of phytoplankton primary production (PP) and chlorophyll a (Chl) wasstudied based on the data carried out in August–September 2015, 2017, and 2018. The PP maximum waslocated at the surface or within the 0–5 m subsurface layer. The subsurface chlorophyll maximum (SCM) wasrecorded at 39% stations on the outer shelf and in the vicinity of the continental slope. The SCM was notdetected along the northward transect (130° E) from the Lena River delta. As in other areas of the WorldOcean, the SCM was located below the upper mixed layer (UML), in the nitracline, near the boundary of theeuphotic zone (1% of photosynthetically active radiation). Generally, the SCM was not accompanied by anadditional PP maximum. The Chl concentration at the SCM did not exceed 1 mg m–3. PP produced withinthe UML and SCM contributed 72 and 23%, respectively, to the integrated primary production (IPP) of thewater column. Our results suggest that the influence of the SCM on IPP was insufficient due to low Chl concentration and PP colimitation by the low light and temperature at these depths.
