The co-distribution of Arctic cod and its seabird predators across the marginal ice zone in Baffin Bay

Elementa: Science of the Anthropocene, 2019
Arctic cod (Boreogadus saida) is the dominant pelagic fish in Arctic seas and a staple food of many arctic predators including several seabird species. Marginal ice zones are known as important feeding locations for seabirds. The hypothesis that thick-billed murre (Uria lomvia), northern fulmar (Fulmarus glacialis) and black-legged kittiwake (Rissa ...

A Vast Valley Network Beneath the Greenland Ice Sheet

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mapping subglacial topography along the margin of the Greenland Ice Sheet was revolutionized by reconciling measurements of ice thickness and surface velocity using the principle of mass conservation. Despite evidence that many subglacial valleys resolved by that method extend upstream, it cannot be applied to the ice sheet's slower‐flowing ...

The First‐Order Crustal Structure and Basin Architecture of the Canadian Arctic Margin

Geochemistry, Geophysics, Geosystems
First‐order sedimentary isopach and depth‐to‐Moho maps have been produced for the first time along the Canadian Arctic margin from legacy seismic profiles, calibrated with two‐dimensional gravity and magnetic modeling and augmented by some younger ...

Weaving Indigenous knowledge systems and Western sciences in terrestrial research, monitoring and management in Canada: A systematic map

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
This systematic map compiles and summarizes studies that have woven Indigenous knowledge systems and Western sciences in research, monitoring and management conducted across terrestrial ecosystems in Canada. The map identifies a total of 177 case studies across 14 species and 19 ecosystems.

Revisiting the status of the Arctic's Last Ice Area as a refuge for marine predators

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract The Last Ice Area (LIA), located north of the Canadian Arctic Archipelago and Greenland, has the Arctic's oldest and thickest sea ice. The LIA is hypothesized to be a potential climate refuge for ice‐dependent top predators as Arctic sea ice continues to decline.

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, Volume 41, Issue 5, Page 686-701, July 2026.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Quantifying Shifts in the Absorption Budget of the Labrador Sea as the Dominant Phytoplankton Group Changes Between Diatoms and Phaeocystis

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Phytoplankton spring blooms in the Labrador Sea are dominated by diatoms, with Phaeocystis spp. (hereafter Phaeocystis) contributing more than 25% to total phytoplankton biomass. However, in 2015 and 2022, large blooms of Phaeocystis were observed, contributing up to 90% of the surface phytoplankton biomass. In this study, we quantified shifts

Effects of Wintertime Snow Depth Assimilation on Summertime Sea Ice Prediction Experiments Utilizing a Fully Coupled Regional Arctic Model With Perfect Boundary Conditions

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract During the past decades, the rapid decline of sea ice in the Arctic Ocean has substantially favored commercial navigation activities in the summertime. Numerical sea ice prediction on a seasonal scale plays a crucial role in guiding the programme of such activities, yet the role of snow depth data assimilation in numerical sea ice prediction ...

Geology of the northern margin of the Trans-Hudson Orogen (Foxe Fold Belt), central Baffin Island, Nunavut

, 2001
The northern flank of the Trans-Hudson Orogen on central Baffin Island comprises, from north to south 1) reworked Archean basement (Rae Province); 2) the Paleoproterozoic Piling Group, which comprises a lower, pas- sive-margin sequence (Dewar Lakes and Flint Lake formations) and an upper, foredeep sequence (Astarte River and Longstaff Bluff formations);

Eddies in Seasonally Ice‐Covered Fjords of the Northern Canadian Arctic Archipelago

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract We present the first direct observations of cyclonic passing and standing eddies within landfast ice‐covered fjords where wind stress is unavailable to drive the eddies. Using a series of winter and spring 2025 in situ observations from the northern Canadian Arctic Archipelago, we identify three baroclinic eddies beneath the landfast ice cover.
