Long-term forecasting methods of dates of ice break-up and disappearance at the Dnipro Cascade Reservoirs by teleconnection indicators

open access: yesГеофизический журнал, 2023
Long-term forecasting of the ice regime at the Dnipro Cascade Reservoirs is very important, first of all, for the operation of hydroelectric power stations. In addition, such forecasts also ensure the work of other sectors of the economy, namely shipping,

Development of a small-scale approach to assess sea ice change using weekly ice charts, with application to Anguniaqvia Niqiqyuam Marine Protected Area

open access: yesArctic Science, 2023
Broad-scale changes in sea ice have been documented across the Arctic; however, less is known about sea ice decline at smaller scales, focused at high-priority areas such as marine protected areas (MPAs) or places identified as important by Indigenous ...

Climate warming shortens ice durations and alters freeze and break-up patterns in Swedish water bodies [PDF]

open access: yesThe Cryosphere, 2022
Increasing air temperatures reduce the duration of ice cover on lakes and rivers, threatening to alter their water quality, ecology, biodiversity, and physical, economical and recreational function.

Discriminant analysis of the freeze-up and break-up conditions in the Inner Mongolia Reach of the Yellow River

open access: yesJournal of Water and Climate Change, 2023
This study divided the total storage potential in a natural channel into the ice production volume and the water storage capacity volume. Thermal factors, hydraulic processes, topography, and ice formation were selected to derive a discriminant equation ...

Climate change and Northern Hemisphere lake and river ice phenology from 1931–2005 [PDF]

open access: yesThe Cryosphere, 2021
At high latitudes and altitudes one of the main controls on hydrological and biogeochemical processes is the breakup and freeze-up of lake and river ice.

Delay in Arctic Sea Ice Freeze-Up Linked to Early Summer Sea Ice Loss: Evidence from Satellite Observations

open access: yesRemote Sensing, 2021
The past decades have witnessed a rapid loss of the Arctic sea ice and a significant lengthening of the melt season. The years with the lowest summertime sea ice minimum were found to be accompanied by the latest freeze-up onset on record.

SELF v1.0: A minimal physical model for predicting time of freeze-up in lakes [PDF]

open access: yesGeoscientific Model Development, 2021
Abstract. Predicting the freezing time in lakes is pursued by means of complex mechanistic models or by simplified statistical regressions considering integral quantities. Here, we propose a minimal model (SELF) built on sound physical grounds, which focuses on the pre-freezing period that, in dimictic lakes, goes from mixed conditions (lake ...

Longer thaw seasons increase nitrogen availability for leaching during fall in tundra soils [PDF]

open access: yes, 2016
Climate change has resulted in warmer soil temperatures, earlier spring thaw and later fall freeze-up, resulting in warmer soil temperatures and thawing of permafrost in tundra regions.

Atmospheric conditions during the Arctic Clouds in Summer Experiment (ACSE): Contrasting open-water and sea-ice surfaces during melt and freeze-up seasons [PDF]

open access: yes, 2016
The Arctic Clouds in Summer Experiment (ACSE) was conducted during summer and early autumn 2014, providing a detailed view of the seasonal transition from ice melt into freeze-up.

Unidirectional freeze casting of compressible metallic aerogel composed of freeze-dried cellulose nanofibers and silver nanowires

open access: yesMicro and Nano Systems Letters, 2023
Metallic aerogels have attracted tremendous interest because of their superior properties, such as low density, high electrical conductivity, and large specific surface area. However, extremely brittle connections in their 3D networks remain a challenge.
