Meltwater sources and sinks for multiyear Arctic sea ice in summer [PDF]
The Cryosphere, 2021 On Arctic sea ice, the melt of snow and sea ice generate a summertime flux of fresh water to the upper ocean. The partitioning of this meltwater to storage in melt ponds and deposition in the ocean has consequences for the surface heat budget, the sea ...

Diving for the Sedimentary Record of Multiyear Sea Ice [PDF]
Oceanography, 2012 How is sediment transported to the seafloor along coastlines where the sea ice rarely melts? Are there distinctive characteristics of the resulting deposits that label them as accumulating in this setting that is so sensitive to climate change?

Fracture of multiyear sea ice [PDF]
Journal of Geophysical Research: Oceans, 1998 The fracture and flow of multiyear sea ice was investigated under triaxial compression and uniaxial tension in the temperature range −40° to −3.5°C, for strain rates from 10−7 to 10−2s−1 and for confining pressures up to 30 MPa using 40 mm diameter specimens.

Driving Mechanisms of an Extreme Winter Sea Ice Breakup Event in the Beaufort Sea
Geophysical Research Letters, 2022 The thick multiyear sea ice that once covered large parts of the Arctic is increasingly being replaced by thinner and weaker first‐year ice, making it more vulnerable to breakup by winds.

Geophysical Research Letters, 2021 Historically multiyear sea ice (MYI) covered a majority of the Arctic and circulated through the Beaufort Gyre for years. However, increased ice melt in the Beaufort Sea during the early-2000s was proposed to have severed this circulation. Constructing a regional MYI budget from 1997-2021 reveals that MYI import into the Beaufort Sea has increased year-

The Seasonal-to-Multiyear Large Ensemble (SMYLE) prediction system using the Community Earth System Model version 2 [PDF]
Geoscientific Model Development, 2022 The potential for multiyear prediction of impactful Earth system change remains relatively underexplored compared to shorter (subseasonal to seasonal) and longer (decadal) timescales.

Multiyear Fast Ice along the Taymyr Peninsula, Siberia [PDF]
ARCTIC, 1995 A 20 km wide zone of fast ice, reaching offshore to the 20 m isobath and sealing off coastal embayments along the Taymyr Peninsula, survived until at least 23 November 1993, becoming multiyear land-fast sea ice (MLSI). Barrier islands show characteristic recurved spits indicating dominant southeastward direction of longshore transport in intermittent ...

A scatterometer record of sea ice extents and backscatter: 1992–2016 [PDF]
The Cryosphere, 2018 This paper presents the first long-term climate data record of sea ice extents and backscatter derived from intercalibrated satellite scatterometer missions (ERS, QuikSCAT and ASCAT) extending from 1992 to the present date (Verhoef et al., 2018 ...

ASSESSMENT OF SEA ICE FREEBOARD AND THICKNESS IN MCMURDO SOUND, ANTARCTICA, DERIVED BY GROUND VALIDATED SATELLITE ALTIMETER DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 This investigation employs the use of ICESat to derive freeboard measurements in McMurdo Sound in the western Ross Sea, Antarctica, for the time period 2003-2009. Methods closely follow those previously presented in the literature but are complemented by
