The impact of ice structures and ocean warming in Milne Fiord Open
Arctic tidewater glaciers and ice shelves are undergoing rapid attrition, with warmer ocean temperatures playing an important role. However, the relationship between ocean temperature and ice structure retreat is complex and may change as …

The role of preconditioning on landfast sea ice break-off processes in Admiralty Inlet, Nunavut Open
Due to changes in the Arctic climate, the timing of spring break-up of landfast sea ice has become less predictable in recent years, which has implications for the traditional lifestyle of Inuit and shipping operations. We use satellite im…

Evaluation of ice island ‘footloose’ calving events using finite element analysis Open
Ice islands, massive tabular icebergs, are known to fracture as they drift. The footloose mechanism occurs when a large protuberance, known as a ram, develops along the submerged edge of the ice island and induces a buoyancy-driven bending…

Long-term field tracking of icebergs in the eastern Canadian Arctic Open
Tidewater glaciers are those which terminate into the ocean and drain a significant proportion of the Greenland Ice Sheet and ice masses of the Canadian Arctic, providing the primary source of icebergs in Canadian waters. Once calved, ther…

Heat Fluxes in a Glacial Fjord: The Role of Buoyancy‐Driven Circulation and Offshore Forcing Open
The ocean supplies large quantities of thermal energy to tidewater glaciers, but the mechanisms behind the heat delivery are not fully understood. To examine heat flux dynamics in glacial fjords, we run an 8‐year realistic numerical simula…

Grounding-line retreat of Milne Glacier, Ellesmere Island, Canada over 1966–2023 from satellite, airborne, and ground radar data Open
Milne Glacier is a marine-terminating glacier located on the northern coast of Ellesmere Island in the Canadian High Arctic, a region that has experienced extensive ice-mass loss over the last two decades. Milne Glacier flows into Milne Fi…

Evaluating the importance of footloose-type failure in ice island deterioration modeling Open
The drift and deterioration of large and tabular icebergs, also known as “ice islands” in the Arctic, are modeled for both operational (e.g., offshore risk mitigation) and research (e.g., oceanographic impact of melt water input) purposes.…

Unsteady Circulation in a Glacial Fjord: A Multiyear Modeling Study of Milne Fiord Open
The exchange of heat and freshwater between glaciers and the ocean is dictated by the circulation in glacial fjords and ice shelf cavities. Therefore, our ability to estimate and predict these fluxes depends on our understanding of the cir…
View article: Sea Ice‐Driven Iceberg Drift in Baffin Bay
Sea Ice‐Driven Iceberg Drift in Baffin Bay Open
Baffin Bay is the travel destination of most icebergs calving from west Greenland. They commonly follow the bay's cyclonic circulation and might end up far south along the coast of Newfoundland and Labrador, where many shipping routes conv…

The complex basal morphology and ice dynamics of the Nansen Ice Shelf, East Antarctica Open
Ice shelf dynamics and morphology play an important role in the stability of floating bodies of ice by driving fracturing that can lead to calving, in turn impacting the ability of the ice shelf to buttress upstream grounded ice. Following…

Cryologger Ice Tracking Beacon: A Low-Cost, Open-Source Platform for Tracking Icebergs and Ice Islands Open
Icebergs and ice islands (large, tabular icebergs) present a significant hazard to marine vessels and infrastructure at a time when demand for access to Arctic waters is increasing. There is a growing demand for in situ iceberg tracking da…

Seasonal Sea Ice Conditions Affect Caribou Crossing Areas Around Qikiqtaq, Nunavut: Uqsuqtuurmiut Knowledge Guides Ice Chart Analysis Open
Though polar ecologists consider sea ice primarily as a habitat for marine mammals, caribou use sea ice to complete their reproductive cycles, to access areas with preferred climatic and vegetation conditions, and to avoid predators season…

Developments to 2D modelling of ice island deterioration using the CI2D3 Database Open
The calving of ice tongues and ice shelves can generate large, tabular icebergs that have climatological implications given their role in dispersing freshwater from the Greenland and Antarctic ice sheets. These ‘ice islands’ al…

Ice Island and Iceberg Fluxes from Canadian High Arctic Sources Open
This project was initiated by the Northern Transportation Adaptation Initiative with the aim of quantifying the production rates of ice islands and icebergs in the Canadian High Arctic. A first step toward understanding the risk that these…

Assessing Ice Island Drift Patterns, Ice Island Grounding Locations, and Gridded Bathymetry Products between Nares Strait and the North Atlantic Open
Large, tabular icebergs known as “ice islands” frequently transit the eastern Canadian Arctic and sub-Arctic after breaking away from ice tongues in northern Greenland. Here, we mine the Canadian Ice Island Drift, Deterioration and Detecti…
