Arctic marginal ice zone interannual variability and change point detection using two definitions (1983–2022)

Environmental Research Letters, 2023
The ongoing decline in Arctic sea ice extent and thickness underscores the scientific significance of monitoring the marginal ice zone (MIZ), a transitional region between the open ocean and pack ice.

Spatial and temporal variability in the snowpack of a High Arctic ice cap: implications for mass-change measurements [PDF]

, 2008
Interpretation of ice mass elevation changes observed by satellite altimetry demands quantification of the proportion of elevation change which is attributable to variations in firn densification.

Assessing the representation of Arctic sea ice and the marginal ice zone in ocean–sea ice reanalyses [PDF]

The Cryosphere
The recent development of data-assimilating reanalyses of the global ocean and sea ice enables a better understanding of the polar region dynamics and provides gridded descriptions of sea ice variables without temporal and spatial gaps.

Can uncertainties in sea ice albedo reconcile patterns of data-model discord for the Pliocene and 20th/21st centuries? [PDF]

, 2014
General Circulation Model simulations of the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Myr ago) currently underestimate the level of warming that proxy data suggest existed at high latitudes, with discrepancies of up to 11°C for sea surface ...

Estimation Method for Ice load of Managed Ice in an Oblique Condition

한국해양공학회지, 2018
Recently, as sea ice in the Arctic has been decreasing due to global warming, it has become easier to develop oil and gas resources buried in the Arctic region.

Vertical profiling of aerosol particles and trace gases over the central Arctic Ocean during summer [PDF]

Atmospheric Chemistry and Physics, 2013
Unique measurements of vertical size-resolved aerosol particle concentrations, trace gas concentrations and meteorological data were obtained during the Arctic Summer Cloud Ocean Study (ASCOS, www.ascos.se), an International Polar Year project aimed at ...

Topography-albedo feedback reinforces the transition to a younger Arctic ice pack

Communications Earth & Environment
Over the past few decades, the Arctic sea ice cover has rapidly shifted from consisting largely of thicker multiyear ice to predominantly thinner first-year ice. While ice-albedo feedback and reductions in overall ice extent have received a great deal of

Spatial and Temporal Variations in the Extent and Thickness of Arctic Landfast Ice

Remote Sensing, 2019
Analyses of landfast ice in Arctic coastal areas provide a comprehensive understanding of the variations in Arctic sea ice and generate data for studies on the utilization of the Arctic passages.

The effect of sea-ice parameterizations on the simulation of the Arctic ice pack [PDF]

Annals of Glaciology, 1997
A one-dimensional (1-D), thermodynamic sea-ice model with parameterized ice dynamics is coupled to a mixed-layer ocean model and driven with prescribed atmospheric forcings for the central Arctic.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.
