How Sea Ice Drift Influences Sea Ice Area and Volume [PDF]
Geophysical Research Letters, 2021 AbstractEquatorward sea ice drift can have competing impacts on the sea ice cover. On one hand, as ice reaches warmer waters it will be subject to faster melt. On the other hand, the ice near the pole will thin, causing faster ice growth when air temperatures are below freezing.

Surface roughness signatures of summer arctic snow-covered sea ice in X-band dual-polarimetric SAR
GIScience & Remote Sensing, 2020 Surface roughness of sea ice is primary information for understanding sea ice dynamics and air–ice–ocean interactions. Synthetic aperture radar (SAR) is a powerful tool for investigating sea ice surface roughness owing to the high sensitivity of its ...

INCORRECT MATCH DETECTION METHOD FOR ARCTIC SEA-ICE RECONSTRUCTION USING UAV IMAGES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 Shapes and surface roughness, which are considered as key indicators in understanding Arctic sea-ice, can be measured from the digital surface model (DSM) of the target area.

MOSAICKING VERY-HIGH-RESOLUTION HELICOPTER-BORNE IMAGES ACQUIRED OVER DRIFTING ARCTIC SEA ICE USING COTS SENSORS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 In order to observe and record conditions of the sea ice efficiently and specifically during in-situ investigation with the support of icebreaker research vessel (IBRV), the very-high-resolution (VHR) imaging systems have been used in recent past.

Ice platelets below Weddell Sea landfast sea ice [PDF]
Annals of Glaciology, 2015 AbstractBasal melt of ice shelves may lead to an accumulation of disc-shaped ice platelets underneath nearby sea ice, to form a sub-ice platelet layer. Here we present the seasonal cycle of sea ice attached to the Ekström Ice Shelf, Antarctica, and the underlying platelet layer in 2012. Ice platelets emerged from the cavity and interacted with the fast-

Tracer Measurements in Growing Sea Ice Support Convective Gravity Drainage Parameterizations [PDF]
, 2020 Gravity drainage is the dominant process redistributing solutes in growing sea ice. Modeling gravity drainage is therefore necessary to predict physical and biogeochemical variables in sea ice.

Retrieval and parameterisation of sea-ice bulk density from airborne multi-sensor measurements [PDF]
The Cryosphere, 2022 Knowledge of sea-ice thickness and volume depends on freeboard observations from satellite altimeters and in turn on information of snow mass and sea-ice density required for the freeboard-to-thickness conversion.

The impact of Arctic sea ice loss on mid-Holocene climate. [PDF]
, 2018 Mid-Holocene climate was characterized by strong summer solar heating that decreased Arctic sea ice cover. Motivated by recent studies identifying Arctic sea ice loss as a key driver of future climate change, we separate the influences of Arctic sea ice ...
