       'We investigate how a topographic slope impacts eddy diffusivities in a two-layer quasi-geostrophic model. There are asymmetric effects of retrograde slopes, where the layer interface and the topography tilt in the same direction, and prograde slopes, where the interface and topography tilt in opposite directions. Moreover, there is asymmetry between the upper and lower layer. Steep retrograde slopes suppress the eddy diffusivity in both layers compared to flat or weak slopes. With a strong prograde slope, coherent, long-lived vortices form in the upper layer; as these are surface-trapped, they are not influenced by topography or bottom friction, and the diffusivity in the upper layer is thus relatively unaffected by the slope. In the lower layer, however, the diffusivities decrease with slope magnitude for both prograde and retrograde slopes. We also compare the Lagrangian diffusivity, derived from particle tracking experiments, and the Eulerian diffusivity, based on the flux-gradient relation for potential vorticity (PV). The two values agree in the upper layer, but not in the lower layer. We present a new expression relating Eulerian and Lagrangian diffusivities, and this correctly captures the differences seen in the lower layer. The difference occurs because bottom friction alters the PV along the particle tracks. The results underline the importance of considering both topographic slopes and bottom friction in parametrizations of mesoscale eddy stirring.',

+      'Eddies can retain water for several months to over a year, but their water properties may change as they move. In the potential spicity-density (π-σ) space, variations in water mass properties are decomposed into a diapycnal component Δσ and an isopycnal component Δπ. This study quantifies the change rate V_λ of water properties of global eddies in this space, where V_λ = d[sqrt(Δσ^2+Δπ^2)]/dt, with a mean value ranging from 0 to 0.03 kg/m^3/day. Using Argo floats and altimetry data, more than 150,000 eddies were sampled by Argo floats, providing over 600,000 profiles from 2000 to 2022. Results show water properties near eddy centers are more conserved than at edges, with higher V_λ during eddy generation and extinction and V_λ decreasing with depth. The 3-D structure of V_λ can be approximated by a unified solution by solving the spicity equation on isopycnal layers. Weaker V_λ values are observed in Lagrangian eddies than in Eulerian eddies, and the Eulerian view overestimates V_λ by ∼50% due to the misattribution of property changes to trapped water that is actually being exchanged. Analogous to decomposing kinetic energy into components, the contribution of isopycnal and diapycnal components to V_λ is given by the fraction of total variance. It is found that the isopycnal component accounts for 50%-70% of V_λ in 0-1000 m, and a larger V_λ is observed in the eddy flanks adjacent to strong currents (e.g., Kuroshio Extension, Gulf Stream). This π-σ decomposition approach may be a useful tool for the eddy research community.',
