Abstract

A complex multydisciplinary oceanographic research was carried out along 358 km transect along the Lena Delta coastline (DCL): 58 stations were accomplished in 7 days in early September 2009. Our study focuses on structure of bottom sediments, dynamics of suspended particulate matter (SPM), content of particulate organic carbon (POC), total nitrogen (ON), C/N value, stable carbon (δ13С) and nitrogen isotopes (δ15N). It has been found a close connection between channels morthology, tectonic features and distribution of bottom sediments, SPM, water runoff along the DCL.Neotectonic movements happened about 6,000 yr BP led to uplift of the DCL western part, which caused redistribution of river runoff to the eastern channels of the DCL. The boundary between these “tectonic” parts of the DCL is the submeridional fault, to which the Tumatsky Channel is currently confined. Shelf waters with salinity (S) > 20‰ penetrated to the channel mouth, causing formation of a frontal hydrological zone with increased gradients of thermohaline characteristics. Almost fresh river waters (SAcknowledgements.
