摘要: Spatial distribution of phytoplankton primary production and chlorophyll was studied based on the data three cruises carried out in August–September 2015, 2017 2018. The average value water column (IPP) along transect from Lena`s mouth to continental slope 2.8 fold higher than that one Khatanga`s mouth, which explained by level incident radiation nutrients concentration. Along cross-slope transects increasing photosynthetically layer integrated (Chl ph ) occurred due developing deep maxima. IPP Chl registered vicinity slope. In averaged < 100 mgC m -2 d -1 is evidence oligotrophy Laptev Sea at end summer beginning autumn.
