Comparison between three implementations of automatic identification algorithms for the quantification and characterization of mesoscale eddies in the South Atlantic Ocean (2011, methodology): “The Chelton et al. (2011) results present diameters ∼50 % larger in high latitudes (south of 30 ◦ S) than the present study. This can be an influence of the Brazil-Malvinas convergence zone and the Agulhas Current retroflexion, since these author results indicate the presence of large structures in ”
The physical oceanography of the transport of floating marine debris (2020, background): “Mesoscale eddies are slowly rotating vortices, with diameters of hundreds of kilometers (technically defined by the scale at which the Rossby number (e.g. Pedlosky 1987) is much less than order one), depths of few hundreds to thousands of meters and lifespans of weeks to years (Chelton et al 2011).”
Spatio-Temporal Consistency as a Means to Identify Unlabeled Objects in a Continuous Data Field (2014, methodology): “Eddies have also been shown to impact marine ecosystems by raising the deep nutrient-rich water to the surface, which renews the nutrient supply to phytoplankton and subsequently leads to increased fish production (Denman and Gargett 1983; Chelton et al. 2011).”
Deep-learning-based information mining from ocean remote-sensing imagery (2020, methodology): “Automatic eddy-identification algorithms include the physical-parameter-based method [64–66], the flow-direction-based method [67] and the SSH-based method [61].”
Submesoscale Instability and Generation of Mesoscale Anticyclones near a Separation of the California Undercurrent (2015, background): “Altimetric measurements show that the surface mesoscale eddy field in the CCS is a nearly equal mixture of cyclones and anticyclones (Chelton et al. 2011).”
On the global estimates of geostrophic and Ekman surface currents (2013, background): “Repeated satellite observations of sea level offer the opportunity to study mesoscale eddies through the geostrophic approximation over the ocean (Chelton et al. 2011).”
Southern Ocean eddy phenomenology (2015, background): “…phase speeds from the ones of baroclinic Rossby waves and the small poleward and equatorward deflection of cyclones and anticyclones, respectively [Cushman-Roisin et al., 1989; Morrow, 2004; Van Leeuwen, 2007], as well as for eddy-eddy interactions [Chelton et al., 2011b; Early et al., 2011].”
The Canadian Earth System Model version 5 (CanESM5.0.3) (2019, background): “The first modification is motivated by the observational evidence suggesting that away from the tropics the eddy scale decreases less rapidly than does the Rossby radius (e.g. Chelton et al., 2011).”
A Big Data Guide to Understanding Climate Change: The Case for Theory-Guided Data Science (2014, background): “32 However, the patterns identiﬁed were not analyzed based on a simple physical fact that eddies are theoretically axisymmetric Gaussian features 33 with a single extremum (maximum or minimum).”
EddyScan: A physically consistent ocean eddy monitoring application (2012, methodology): “but does not address the issue of merging smaller eddies together (see Appendix B in [7]).”
Modulation of Wind-Work by Oceanic Current Interaction with the Atmosphere (2016, methodology): “In particular, the AVISO data have spatial and temporal resolution issues and see only the larger mesoscale eddies (Chelton et al. 2011).”
The Evolution and Propagation of Quasigeostrophic Ocean Eddies (2011, background): “The nonlinear anticyclonic eddy also shows a much slower amplitude decay rate and an equatorward deflection (McWilliams and Flierl 1979), both qualitatively consistent with the observations reported by Morrow et al. (2004) and Chelton et al. (2007, 2011).”
