Land-Ocean Systems in the Siberian Arctic: Dynamics and History
species. Such mass species as L. macrurus and 1. tolly, characteristic of the summer
zooplankton of the area, were not found in spring evidently due to specific features of their life
cycle. The observation period was time of reproduction of D. bungei dominating in abundance
at most stations. In May-June spawning of one of the species of Pseudocalanus genus
(assumingly P. minutus) was observed. The distribution pattern of zooplankton in the
observation area is highly affected by water salinity. Mass brackishwater species (D. bungei, A.
longiremis, Pseudocalanus sp) were occurring in spring-time zooplankton along the whole
range of salinity. In June the enrich of plankton by freshwater elements to the east of the LenaDelta is one more improve of the fact that the area receives maximum of river runoff.

The author is sincerely grateful to the organizers of the Transdrift-IV expedition for the
possibility to study the Laptev Sea in a most intriguing season. The author is also thankful to
Dr. A.Yu. Gukov (Tiksi Hydrometeorological Department) for his direct participation in
zooplankton sampling during the expedition.
