Osmium behavior in estuaries: the Lena River example

Earth and Planetary Science Letters, 2000
The behavior of dissolved osmium at the river/ocean interface was studied in the Lena River estuary. Dissolved osmium removal is observed at very low salinities. The loss is estimated to be 28% of the dissolved concentration of the river. The removal cannot be related to the flocculation of iron oxide–organic matter colloids, but occurs simultaneously ...

Changes in the Lena River runoff during the Holocene [PDF]

open access: yesWater Resources, 2009
The spatial and temporal changes in the Lena River runoff over the last 9 thousand years are reconstructed through studying the freshwater microfossils in sediment cores obtained from the Laptev Sea inner shelf immediately adjacent to the Lena delta and subject to the freshening effect of river water inflowing the sea through the main arms of the delta

Long-term annual water balance analysis of the Lena River [PDF]

open access: yesGlobal and Planetary Change, 2005
Historical data analyses show that the Lena River and its major tributaries experienced an extended low water period over 1936–1957 and high water periods over 1974–1983 and 1988–2001.

Modeling of the river discharge from the Lena River Basin

SPIE Proceedings, 2014
Climatic model of the river runoff with 1/3 degree resolution is presented in the paper. The model is the linear reservoir model i.e., each cell in the model is the reservoir or the cascade of the reservoirs. Data of the ERA40 and MERRA reanalysis for the numerical modeling of the river runoff for the Lena River was used as well as the comparison with ...

TROVANTS OF THE LENA RIVER: HYPOTHESIS AND FORMATION MODEL

Geology and mineral resources of Siberia, 2021
Unusual nodule formations have long been known in the steep banks of the Lena River and its tributaries. Their belonging to the category of Trovants (trovantogenesis) has been established. It is shown that trovants formation (trovantogenesis) is a process of specific transformation of cemented sands to varying degrees in platform and sub-platform ...

Hydrochemical Conditions at the Lena River in August 2018

Oceanology, 2019
The information is presented on hydrochemical studies performed in August 2018 at the middle and lower reaches of the Lena River from Yakutsk to Kyusyur settlements. The studies resulted in generating the database containing 80 parameters of water chemical composition including the stable isotopes of water, particulate matter, and DOC.
