The spatiotemporal patterns of sea ice in the Bohai Sea during the winter seasons of 2000–2016

International Journal of Digital Earth, 2019
In this study, sea ice thickness (SIT) and sea ice extent (SIE) in the Bohai Sea from 2000 to 2016 were investigated. A surface heat balance equation was applied to calculate SIT using ice surface temperatures estimated from the Moderate Resolution ...

Rapid Decline of Total Antarctic Sea Ice Extent during 2014–16 Controlled by Wind-Driven Sea Ice Drift

Journal of Climate, 2019
Between 2014 and 2016 the annual mean total extent of Antarctic sea ice decreased by a record, unprecedented amount of 1.6 × 106 km2, the largest in a record starting in the late 1970s. The mechanisms behind such a rapid decrease remain unknown.

Interannual and seasonal variability of Arctic sea ice extent according to satellite observations

Российская Арктика, 2019
The interannual and seasonal changes of Arctic sea ice extent according to satellite observations from 1978–2018 are analyzed. Steady reduction in the sea ice cover over the research period is reported.

Impacts of Oceanic and Atmospheric Heat Transports on Sea Ice Extent [PDF]

Journal of Climate, 2020
AbstractClimate-model biases in ocean heat transport (OHT) have been proposed as a major contributor to uncertainties in projections of sea ice extent. To better understand the impact of OHT on sea ice extent and compare it to that of atmospheric heat transport (AHT), an idealized, zonally averaged energy balance model (EBM) is developed.

Record Early Sea Ice Loss in Southeastern Hudson Bay in Spring 2024

Geophysical Research Letters
Hudson Bay seasonal sea‐ice cover plays an important role in marine ecosystems and human activities. Spring 2024 witnessed a uniquely early southeastern opening, leading to basin‐wide sea ice extent falling 5σ below the 1979–2023 average.

Modeled Arctic sea ice evolution through 2300 in CMIP5 extended RCPs [PDF]

The Cryosphere, 2014
Almost all global climate models and Earth system models that participated in the Coupled Model Intercomparison Project 5 (CMIP5) show strong declines in Arctic sea ice extent and volume under the highest forcing scenario of the representative ...

Changes of the Arctic marginal ice zone during the satellite era [PDF]

The Cryosphere, 2020
Many studies have shown a decrease in Arctic sea ice extent. It does not logically follow, however, that the extent of the marginal ice zone (MIZ), here defined as the area of the ocean with ice concentrations from 15 % to 80 %, is also ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]

, 2014
Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.

Modeling the annual cycle of daily Antarctic sea ice extent

The Cryosphere, 2019
. The total Antarctic sea ice extent (SIE) experiences a distinct annual cycle, peaking in September and reaching its minimum in February. In this paper we propose a mathematical and statistical decomposition of this temporal variation in SIE.
