Using timing of ice retreat to predict timing of fall freeze‐up in the Arctic [PDF]

open access: yesGeophysical Research Letters, 2016
Reliable forecasts of the timing of sea ice advance are needed in order to reduce risks associated with operating in the Arctic as well as planning of human and environmental emergencies.

Sea ice breakup and freeze-up indicators for users of the Arctic coastal environment [PDF]

open access: yesThe Cryosphere, 2022
The timing of sea ice retreat and advance in Arctic coastal waters varies substantially from year to year. Various activities, ranging from marine transport to the use of sea ice as a platform for industrial activity or winter travel, are affected by ...

Temporal and Spatial Evolution of Seasonal Sea Ice of Arctic Bay, Nunavut

open access: yesCoasts, 2023
The temporal and spatial variation in seasonal sea ice in Arctic Bay, Nunavut, are examined using time series and spatial clustering analyses. For the period of 1971 to 2018, a time series of sea ice break-up, and freeze-up, dates and ice-free season ...

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.

Development of an ice-jam flood forecasting modelling framework for freeze-up/winter breakup

open access: yesHydrology Research, 2023
River ice-jams can create severe flooding along many rivers in cold regions. While ice-jams often form during the spring breakup, the mid-winter breakup can cause ice-jamming and flooding.

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.
