Bathymetry constrains ocean heat supply to Greenland's largest glacier tongue

J Schaffer, T Kanzow, WJ von Appen… - Nature …, 2020 - nature.com
Mass loss from the Greenland ice sheet has increased over the past two decades, currently
accounting for 25% of global sea-level rise. This is due to increased surface melt driven by …

[HTML][HTML] Acceleration and overturning of the Antarctic Slope Current by winds, eddies, and tides

AL Stewart, A Klocker… - Journal of Physical …, 2019 - journals.ametsoc.org
All exchanges between the open ocean and the Antarctic continental shelf must cross the
Antarctic Slope Current (ASC). Previous studies indicate that these exchanges are strongly …

Ocean circulation and variability beneath Nioghalvfjerdsbræ (79 North Glacier) ice tongue

MR Lindeman, F Straneo, NJ Wilson… - Journal of …, 2020 - Wiley Online Library
The floating ice tongue of 79 North Glacier, a major outlet glacier of the Northeast Greenland
Ice Stream, has thinned by 30% since 1999. Earlier studies have indicated that long‐term …

Hydraulic suppression of basal glacier melt in sill fjords

J Nilsson, E van Dongen, M Jakobsson… - The …, 2023 - tc.copernicus.org
Using a conceptual model, we examine how hydraulically controlled exchange flows in
silled fjords affect the relationship between the basal glacier melt and the features of warm …

On the role of bottom pressure torques in wind-driven gyres

AL Stewart, JC McWilliams… - Journal of Physical …, 2021 - journals.ametsoc.org
Previous studies have concluded that the wind-input vorticity in ocean gyres is balanced by
bottom pressure torques (BPT), when integrated over latitude bands. However, the BPT must …

[HTML][HTML] Geometric constraints on glacial fjord–shelf exchange

KX Zhao, AL Stewart… - Journal of Physical …, 2021 - journals.ametsoc.org
The oceanic connections between tidewater glaciers and continental shelf waters are
modulated and controlled by geometrically complex fjords. These fjords exhibit both …

Bistability of the Filchner‐Ronne ice shelf cavity circulation and basal melt

JE Hazel, AL Stewart - Journal of Geophysical Research …, 2020 - Wiley Online Library
Circulation and water mass transformation within the Filchner‐Ronne Ice Shelf (FRIS) cavity
create precursors to Antarctic bottom water, which closes the global overturning circulation …

[HTML][HTML] Does topographic form stress impede prograde ocean currents?

Y Bai, Y Wang, AL Stewart - Journal of Physical …, 2021 - journals.ametsoc.org
Topographic form stress (TFS) plays a central role in constraining the transport of the
Antarctic Circumpolar Current (ACC), and thus the rate of exchange between the major …

Standing eddies in glacial fjords and their role in fjord circulation and melt

KX Zhao, AL Stewart, JC McWilliams… - Journal of Physical …, 2023 - journals.ametsoc.org
Glacial fjord circulation modulates the connection between marine-terminating glaciers and
the ocean currents offshore. These fjords exhibit a complex 3D circulation with overturning …

Delayed freshwater export from a Greenland tidewater glacial fjord

R Sanchez, D Slater, F Straneo - Journal of Physical …, 2023 - journals.ametsoc.org
Abstract Freshwater from the Greenland Ice Sheet is routed to the ocean through narrow
fjords along the coastline where it impacts ecosystems both within the fjord and on the …
