Impact of atmospheric cooling on the high‐frequency submesoscale vertical heat flux

J Aparco‐Lara, HS Torres… - Journal of Geophysical …, 2023 - Wiley Online Library
Recent simulations suggest that submesoscale motions with scales smaller than 30 km and
frequencies greater than 1 day− 1 drive upward vertical heat transport. These simulations …

Modeling iceberg longevity and distribution during Heinrich Events

M Fendrock, A Condron… - Paleoceanography and …, 2022 - Wiley Online Library
During the last glacial period (120–12 ka), the Laurentide ice sheet discharged large
numbers of icebergs into the North Atlantic. These icebergs carried sediments that were …

Asymmetry of submesoscale instabilities in anticyclonic and cyclonic eddies

W Shi, H Lin, Q Deng, J Hu - Geophysical Research Letters, 2024 - Wiley Online Library
The upper‐ocean relative vorticity has been found to be cyclonically skewed, but altimetry
observations indicate that long‐lifespan mesoscale eddies tend to be anticyclonic. We are …

Modeling the Production of Heinrich Layers With a Sediment‐Enabled Iceberg Model

M Fendrock, A Condron… - Paleoceanography and …, 2023 - Wiley Online Library
Abstract In the North Atlantic, relatively coarse grained sediments can be found periodically
throughout sediment cores spanning the Last Glacial Period. These sediments were rafted …

[HTML][HTML] Virtual laboratory experiments on the interaction of a vortex with small-scale topography

LT Gulliver, T Radko - Physics of Fluids, 2023 - pubs.aip.org
This study presents numerical analogs of laboratory experiments designed to explore the
interaction of broad geophysical flows with irregular small-scale bathymetry. The previously …

Destratifying and restratifying instabilities during down‐front wind events: A case study in the Irminger Sea

FW Goldsworth, HL Johnson… - Journal of …, 2024 - Wiley Online Library
Observations indicate that symmetric instability is active in the East Greenland Current
during strong northerly wind events. Theoretical considerations suggest that mesoscale …

Density Staircases Generated by Symmetric Instability in a Cross‐Equatorial Deep Western Boundary Current

FW Goldsworth, HL Johnson… - Geophysical Research …, 2022 - Wiley Online Library
Density staircases are observed in an idealized model of a deep western boundary current
upon crossing the equator. We propose that the staircases are generated by the excitement …
