Sub-kilometre scale distribution of snow depth on Arctic sea ice from Soviet drifting stations

Journal of Glaciology, 2022
The sub-kilometre scale distribution of snow depth on Arctic sea ice impacts atmosphere-ice fluxes of energy and mass, and is of importance for satellite estimates of sea-ice thickness from both radar and lidar altimeters.

Decadal oscillation provides skillful multiyear predictions of Antarctic sea ice

Nature Communications, 2023
AbstractOver the satellite era, Antarctic sea ice exhibited an overall long-term increasing trend, contrary to the Arctic reduction under global warming. However, the drastic decline of Antarctic sea ice in 2014–2018 raises questions about its interannual and decadal-scale variabilities, which are poorly understood and predicted.

Modelling the evolution of Arctic multiyear sea ice over 2000-2018

The Cryosphere, 2022
Multiyear sea ice (MYI) cover in the Arctic has been monitored for decades using increasingly sophisticated remote sensing techniques, and these have documented a significant decline in MYI over time. However, such techniques are unable to differentiate between the processes affecting the evolution of the MYI.

Linking winter and spring thermodynamic sea-ice states at critical scales using an object-based image analysis of Sentinel-1

Annals of Glaciology, 2018
Changing Arctic sea-ice extent and melt season duration, and increasing economic interest in the Arctic have prompted the need for enhanced marine ecosystem studies and improvements to dynamical and forecast models. Sea-ice melt pond fraction fp has been

Projected polar bear sea ice habitat in the Canadian Arctic Archipelago. [PDF]

PLoS ONE, 2014
Sea ice across the Arctic is declining and altering physical characteristics of marine ecosystems. Polar bears (Ursus maritimus) have been identified as vulnerable to changes in sea ice conditions.

Ocean wave blocking by periodic surface rolls fortifies Arctic ice shelves

Journal of Glaciology, 2023
The Ward Hunt and Milne ice shelves are the present-day remnants of a much larger ice shelf that once fringed the coast of Ellesmere Island, Canada. These ice shelves possess a unique surface morphology consisting of wave-like rolls that run parallel to ...

Attribute-Based Interpretation of Ground-Penetrating Radar Data for Improved Sea Ice Thickness Estimation [PDF]

Lithosphere
Accurately estimating the thickness of Arctic multiyear sea ice is essential for understanding cryospheric dynamics and monitoring climate change. Ground-penetrating radar (GPR) is widely used in terrestrial geophysical applications, including subsurface

Anomalous Floe Dynamics in Nares Strait: A Case Study of Ice Arch Formation

Remote Sensing
Nares Strait is a narrow channel situated between Ellesmere Island and Greenland, through which the prevailing winds and surface current transport multiyear ice southward from the Arctic Ocean. Seasonal formation of ice arches at the northern or southern

The triggers of the disaggregation of Voyeykov Ice Shelf (2007), Wilkes Land, East Antarctica, and its subsequent evolution

Journal of Glaciology, 2021
The weakening and/or removal of floating ice shelves in Antarctica can induce inland ice flow acceleration. Numerical modelling suggests these processes will play an important role in Antarctica's future sea-level contribution, but our understanding of ...

Smart Cities Leading the Green Transition: Linking Open Innovation and Entrepreneurial Dynamics

Business Strategy and the Environment, EarlyView.
ABSTRACT Smart cities today are vibrant spaces where technology, collaboration, and sustainability come together to shape a better future. The green transition in cities is not just about building greener infrastructure or cutting emissions. It also changes how people, institutions, and businesses think and act.
