“…Ранее была описана широтная зональность в структуре сообществ фитопланктона на разрезе "Лена" [9]. В качестве границ распространения южного комплекса видов, фитопланктона внешнего шельфа и северного комплекса фитопланктона были приняты разделы между изогалинами соответственно 8-18 и 22-27 psu.…”

Spatial variability of primary production and chlorophyll in the Laptev sea in august–september

et al. 2019

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

The abundance and biomass of picophytoplankton, the total concentration of chlorophyll “a”, and the contribution of the picofraction to chlorophyll “a” were studied in the Laptev Sea in 2017. These were the first data for the western sea area. An increase in picophytoplankton abundance in the eastern part of the sea in comparison with that in 1991 was not revealed. The contribution of the picofraction to chlorophyll “a” was the highest (to 56%) in areas with a low total concentration of chlorophyll “a”.

Zooplankton impact on the organic matter flux of Siberian Arctic seas

et al. 2017

View full text Add to dashboard Cite

Role of zooplankton in the organic matter flux was studied in the Kara and Laptev seas using sediment traps in the course of voyage 63 of the Academician Mstislav Keldysh research vessel in August-October 2015. The values of the total flux and that of organic matter were at least an order of magnitude higher than those obtained before the 2000s. A hypothesis is proposed on an increasing influence of the river runoff on the Kara Sea area under climatic changes. Zooplankton contribution into C flux varied broadly, averaging 50%. The highest flux values and contribution of zooplankton in them (up to 96%) were recorded in the frontal (gradient) zones.
