Southern Ocean eddy phenomenology (2015, methodology): “This is a better proxy for the dynamic intensity of an eddy than either Le or A by themselves as it is related to the swirl velocity, which in turn is frequently employed in combination with the eddy propagation speed to assess the eddy ‘‘nonlinearity’’ [Flierl, 1981; Chelton et al., 2007].”
Submesoscale Instability and Generation of Mesoscale Anticyclones near a Separation of the California Undercurrent (2015, background): “The CCS mesoscale eddy field is best known through its surface signatures in drifter trajectories and sea surface height fluctuations (Swenson and Niiler 1996; Stegmann and Schwing 2007; Chelton et al. 2007).”
Global observations of nonlinear mesoscale eddies (2011, positive): “…variance of the 20 (cid:2) (cid:4) 10 (cid:2) high-pass ﬁltered SSH ﬁelds is A very liberal estimate of the contributions of compact eddies to SSH variance can be obtained by assuming that all of the SSH within the boundary of each eddy can be attributed to that eddy (e.g., Chelton et al., 2007).”
Heat balance and eddies in the Peru-Chile current system (2012, background): “Previous censuses for PCS surface eddies in altimeter observations are Chaigneau et al. (2008) and Chelton et al. (2007).”
The Biological carbon pump in the North Atlantic (2014, background): “other basins: the double gyre system of the subtropical and subpolar regions separated by a strong transition zone (the North Atlantic Current) (Sverdrup, 1947; Stommel, 1948; Munk, 1950), upwelling on the eastern margin (Schmitz and McCartney, 1993) and an active eddy field (Heywood et al., 1994; O”
Significant sink of ocean-eddy energy near western boundaries (2010, background): “Ocean eddies are observed to propagate westwards at speeds similar to the phase speeds of classical Rossby wave”
Statistics of vertical vorticity, divergence, and strain in a developed submesoscale turbulence field (2013, background): “The R01 study area in the Eastern Pacific is remote from major western boundary current systems and therefore characterized by a weak mesoscale eddy field [Chelton et al., 2007].”
Evidence for Enhanced Eddy Mixing at Middepth in the Southern Ocean (2009, background): “The scales of the fastest- growing mode are O(10 km) (figure not shown here), much smaller than the scale of the most energetic eddies in the ACC (Stammer 1997; Chelton et al. 2007). This is discussed at length in Smith (2007), where it is argued that the observed scale is likely the result of an in”

Jets and Topography: Jet Transitions and the Impact on Transport in the Antarctic Circumpolar Current (2012, background): “While EKE levels are observed to be elevated in the lee of topography (Chelton et al. 2007), Sallée et al. (2011) show that enhanced EKE levels are not sufficient by itself to imply large eddy diffusivities or, indeed, large particle exchange.”
A Vector Geometry–Based Eddy Detection Algorithm and Its Application to a High-Resolution Numerical Model Product and High-Frequency Radar Surface Velocities in the Southern California Bight (2010, methodology): “Despite this method being frequently used to detect eddies from sea level altimetry (SLA) data (i.e., Isern-Fontanet et al. 2003; Morrow et al. 2004; Chelton et al. 2007), the velocity derivatives induce extra noise in the W field.”
Universal structure of mesoscale eddies in the ocean (2013, background): “The satellite altimetry provides nearly global maps of detailed signatures of eddies at the surface [Chelton et al., 2011, 2007], but it offers no information at subsurface.”
