Thickness distribution of Antarctic sea ice [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2008
Ship‐based observations are used to describe regional and seasonal changes in the thickness distribution and characteristics of sea ice and snow cover thickness around Antarctica. The data set comprises 23,373 observations collected over more than 2 decades of activity and has been compiled as part of the Scientific Committee on Antarctic Research ...

An assessment of Antarctic sea-ice thickness in CMIP6 simulations with comparison to the satellite-based observations and reanalyses [PDF]

open access: yesThe Cryosphere
Sea-ice thickness, though critical to our understanding of sea-ice variability, remains relatively understudied compared to surface sea-ice parameters in the Southern Ocean.

Sea-ice evaluation of NEMO-Nordic 1.0: a NEMO–LIM3.6-based ocean–sea-ice model setup for the North Sea and Baltic Sea [PDF]

open access: yesGeoscientific Model Development, 2017
The Baltic Sea is a seasonally ice-covered marginal sea in northern Europe with intense wintertime ship traffic and a sensitive ecosystem. Understanding and modeling the evolution of the sea-ice pack is important for climate effect studies and ...

The sub-ice platelet layer and its influence on freeboard to thickness conversion of Antarctic sea ice [PDF]

open access: yesThe Cryosphere, 2014
This is an investigation to quantify the influence of the sub-ice platelet layer on satellite measurements of total freeboard and their conversion to thickness of Antarctic sea ice. The sub-ice platelet layer forms as a result of the seaward advection of

Deriving Antarctic Sea‐Ice Thickness From Satellite Altimetry and Estimating Consistency for NASA's ICESat/ICESat‐2 Missions

open access: yesGeophysical Research Letters, 2021
With the launch of the Ice, Cloud and Land Elevation Satellite‐2 (ICESat‐2), densely measuring the Antarctic ocean all year long, monthly sea ice thickness changes can be inspected.

On the timescales and length scales of the Arctic sea ice thickness anomalies: a study based on 14 reanalyses [PDF]

open access: yesThe Cryosphere, 2019
The ocean–sea ice reanalyses are one of the main sources of Arctic sea ice thickness data both in terms of spatial and temporal resolution, since observations are still sparse in time and space.

A New Perspective on Four Decades of Changes in Arctic Sea Ice from Satellite Observations

open access: yesRemote Sensing, 2022
Arctic sea ice characteristics have been changing rapidly and significantly in the last few decades. Using a long-term time series of sea ice products from satellite observations—the extended AVHRR Polar Pathfinder (APP-x)—trends in sea ice concentration,

Winter Arctic sea ice thickness from ICESat-2: upgrades to freeboard and snow loading estimates and an assessment of the first three winters of data collection [PDF]

open access: yesThe Cryosphere, 2023
NASA's ICESat-2 mission has provided near-continuous, high-resolution estimates of sea ice freeboard across both hemispheres since data collection started in October 2018.

Linking Regional Winter Sea Ice Thickness and Surface Roughness to Spring Melt Pond Fraction on Landfast Arctic Sea Ice

open access: yesRemote Sensing, 2017
The Arctic sea ice cover has decreased strongly in extent, thickness, volume and age in recent decades. The melt season presents a significant challenge for sea ice forecasting due to uncertainty associated with the role of surface melt ponds in ice ...

The impact of snow depth, snow density and ice density on sea ice thickness retrieval from satellite radar altimetry: results from the ESA-CCI Sea Ice ECV Project Round Robin Exercise [PDF]

open access: yesThe Cryosphere, 2015
We assess different methods and input parameters, namely snow depth, snow density and ice density, used in freeboard-to-thickness conversion of Arctic sea ice. This conversion is an important part of sea ice thickness retrieval from spaceborne altimetry.
