Characterizing Mesoscale Eddies of Eastern Upwelling Origins in the Atlantic Ocean and Their Role in Offshore Transport

Frontiers in Marine Science, 2022
Motivated by the recurrent formation of eddies in the eastern upwelling areas, we examine cross-basin connectivity that is promoted by coherent, long-lived and long-propagating mesoscale eddies in the Atlantic Ocean.

Compact Mesoscale Eddies in the South Brazil Bight

Remote Sensing, 2022
Recent studies suggest that the South Brazil Bight (SBB) hosts strong westward propagating mesoscale eddies. We use 28 years of satellite altimetry data and a new Eddy Atlas to estimate how much of the eddy kinetic energy (EKE) observed in the SBB is accounted for by local eddies, generated in the Brazil Current (BC) region, versus remote eddies ...

High-latitude eddy statistics from SWOT compared with in situ observations [PDF]

Ocean Science
Mesoscale eddies play a key role in the transport of heat, salt, and momentum in the ocean, yet their statistical characterization at high latitudes has remained elusive due to the coarse resolution of conventional satellite altimetry.

Mesoscale eddies transport deep-sea sediments [PDF]

Scientific Reports, 2014
Mesoscale eddies, which contribute to long-distance water mass transport and biogeochemical budget in the upper ocean, have recently been taken into assessment of the deep-sea hydrodynamic variability. However, how such eddies influence sediment movement in the deepwater environment has not been explored.

How does dynamical spatial variability impact 234Th-derived estimates of organic export? [PDF]

, 2012
In this study we first evaluate the small-scale spatial variability of particulate export, using a set of synoptic thorium-234 activity observations sampled within a one-degree radius.

Damping of climate-scale oceanic variability by mesoscale eddy turbulence

, 2021
International audienceThe impact of mesoscale eddy turbulence on long-term, climatic variability in the ocean's buoyancy structure is investigated using observations from a mooring deployed in the Drake Passage, Southern Ocean.

A daily global mesoscale ocean eddy dataset from satellite altimetry

, 2015
Mesoscale ocean eddies are ubiquitous coherent rotating structures of water with radial scales on the order of 100 kilometers. Eddies play a key role in the transport and mixing of momentum and tracers across the World Ocean.

Southern Ocean response to relative velocity wind stress forcing [PDF]

, 2010
An eddy-resolving quasigeostrophic model of the Southern Ocean coupled to a dynamic atmospheric mixed layer is used to compare the performance of two different wind stress parameterization schemes.

SATELLITE PICTURES OF MESOSCALE EDDIES

Monthly Weather Review, 1962
Abstract Satellite photographs of horizontal eddy patterns are presented and the conditions associated with their formation are discussed. It is shown that some map be purely mechnnical eddies produced by an obstacle (islands) in the flow, others may be the result of inertial oscillation, and others may be produced by inertial instability.
