Polarimetric Scattering Model for Methane Bubbles Trapped in the Ice of Sub-Artic Lakes [PDF]

, 2012
In this work we propose a model for the polarimetric backscattering of shallow sub-arctic lakes, which are frozen usually up to two meters depth during winter.

Alkenone Distributions and Hydrogen Isotope Ratios Show Changes in Haptophyte Species and Source Water in the Holocene Baltic Sea

Geochemistry, Geophysics, Geosystems, 2020
The Baltic Sea, a dynamic, marginal marine basin, experienced a number of large changes in salinity during the Holocene as a result of fluctuations in global and local sea level related to melting of glacial ice sheets and subsequent isostatic rebound ...

Geomorphological evidence of Lake Ladoga Holocene regressions after the Baltic Ice lake drainage (derived from sediment echosounder data)

Limnology and Freshwater Biology, 2022
Abstract. Lake Ladoga has been experiencing frequent water-level fluctuations during the Holocene. Plenty surveys about reconstructions of lake level were published during the last century. They focused on the onshore transgressive sediments and landforms, while a regression below present level was only an assumption.

Russian-Switzerland multi-disciplinary project “Lake Ladoga: life under ice interplay of under-ice processes by global change”

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
The proposed project focuses on the study of the wintertime dynamics of the  System of  Great European lakes (case study  Lake Ladoga). The System of  the  Great European Lakes (Ladoga and Onego) are important resources for drinking water, transport ...

Climate Change in the Baltic Sea : 2021 Fact Sheet [PDF]

, 2021
Climate change effects on the Baltic Sea environment are manifold. It is for example expected that water temperature and sea level will rise, and sea ice cover will decrease.
