Salinity impact on water flow and lake ice in Lake Vostok, Antarctica [PDF]

, 2003
Lake Vostok, isolated from direct exchange with the atmosphere for million years, provides a unique and so far inaccessible habitat. By using a numerical model, and recent lake geometry information, the lake circulation was investigated for different ...

Subglacial Lake Ellsworth: a candidate for in situ exploration in West Antarctica [PDF]

, 2004
Radio-echo sounding reveals a 10 km-long lake beneath similar to3.4 km of ice near the Ellsworth Mountains in West Antarctica, 20 km from the ice divide. Subglacial Lake Ellsworth is located within a distinct topographic hollow, which is similar to1.5 km

Land/sea level changes in southern Finland during the formation of the Salpausselkä endmoraines [PDF]

Bulletin of the Geological Society of Finland, 1969
The altitudes of delta plains of the Salpausselkä endmoraines and of eskers, as well as some determinations of the highest beach level, were used in the study of land/sea level changes. An area south of Hämeenlinna in southern Finland was studied in more

The "tipping" temperature within Subglacial Lake Ellsworth, West Antarctica and its implications for lake access. [PDF]

, 2011
We present results from new geophysical data allowing modelling of the water flow within Subglacial Lake Ellsworth (SLE), West Antarctica. Our simulations indicate that this lake has a novel temperature distribution due to significantly thinner ice than ...

When the River Began—The Formation of River Motala Ström and Human Presence in the Early Holocene, Sweden

Quaternary, 2020
In conjunction with the extensive archaeological projects conducted at the current outlet of Sweden’s second largest lake, Lake Vättern, macrofossil, pollen and diatom records have been studied from 14C-dated lake and river sediments from River Motala ...

Incorporation of particulates into accreted ice above subglacial Vostok lake, Antarctica [PDF]

, 2005
The nature of microscopic particulates in meteoric and accreted ice from the Vostok (Antarctica) ice core is assessed in conjunction with existing ice-core data to investigate the mechanism by which particulates are incorporated into refrozen lake water.

Aleika section an aftersound of the Baltic Ice Lake at the Northern Coast of the Sambian Peninsula

Limnology and Freshwater Biology, 2022
Abstract. We present the new data concerning the traces of the Baltic Ice Lake in the northern coast of the Sambian Peninsula, Kaliningrad region, Russia, based upon the studies of the Aleika section (lithostratigraphy, radiocarbon dating, plant macrofossil, diatom and LOI analyses).

Is Vostok lake in steady state? [PDF]

, 2004
Stable-isotope (D and 18O) data from the Vostok (East Antarctica) ice core are used to explore whether or not subglacial Vostok lake is in isotopic steady state. A simple box model shows that the lake is likely to be in steady state on time-scales of the

Ice conditions in coastal lakes of the southern Baltic Sea [PDF]

Annales de Limnologie - International Journal of Limnology, 2003
This paper describes spatio-temporal variability of the basic ice condition parameters, relationships between selected lakes in terms of those parameters, and frequency of fast (ice cover) and floating ice. Attention is also paid to morphology and topography of ice cover in lakes Jamno, Bukowo, Gardno, and Lebsko during 1960/61-1999/2000. Based on data

The Tuupovaara end moraine in North Karelia, Eastern Finland - an ice-marginal formation of the same age as the Salpausselkä ridges [PDF]

Bulletin of the Geological Society of Finland, 1983
Described in this report is a previously for the most part unknown ice-marginal formation in the province of North Karelia extending from the parish of Värtsilä via Tohmajärvi and Tuupovaara to the parish of Ilomantsi.
