       'Subsurface oxygen maxima (SOM) are recurrent but poorly understood features within the eastern tropical North Pacific oxygen deficient zone (ODZ). Here, we analyze a subsurface oxygen maximum (SOM) observed during the SR2114 cruise using in situ biogeochemical and physical measurements, satellite remote sensing, and Lagrangian particle tracking. The SOM was detected around the 26.4 isopycnal (∼150–200 m) and spatially associated with elevated oxygen concentrations within an otherwise hypoxic environment. Our results show that intense gap winds in the Gulfs of Tehuantepec and Papagayo generate strong upwelling, vertical mixing, and horizontal advection near the coast, potentially allowing subsurface layers to come into contact with surface waters and become oxygenated. The observed vertical penetration of wind-driven features below the Ekman layer also suggests the influence of eddy-wind interactions that reinforce vertical coherence and enhance the offshore transport of oxygen-rich waters. The offshoreward jets observed down to the SOM layer depth highlight the contribution of such coupled processes to ventilating the ODZ interior. Furthermore, float-based observations along isopycnals indicate progressive oxygen loss over time, likely due to local respiration, pointing to dynamic interplay between physical supply and biogeochemical consumption. Together, these findings underscore the pivotal role of coastal wind forcing and mesoscale dynamics in shaping the subsurface oxygen landscape of the eastern tropical North Pacific. The Lagrangian analysis also highlights distinct pathways for water parcels within the ODZ: south of 14°N, water masses are primarily influenced by equatorial currents, whereas in the northern region, water parcels predominantly originate from coastal sources with extended residency times.',

+      'Campeche Escarpment Eddies are deep anticyclonic vortices with no surface expression recently discovered in the deep Gulf of Mexico. The properties of these coherent eddies and the conditions that lead to their formation are studied using a 20-year numerical simulation. This simulation captures the main circulation features of the region and, more importantly, it can reproduce these eddies. Three to five eddies are formed annually, traveling west up to 800 km at average speeds of ~ 3 km dy−1. These eddies extend from the bottom up to 1000m and have average radii of ~ 14 km, orbital velocities ~ 7 cm s−1, Rossby numbers ~ 0.2 and lifetimes over 100 days. Conditions leading to their generation are an intensification of the prograde flow (coast to the right) over the continental slope, anticyclonic vorticity production, separation of the flow from the slope as it passes a cape-canyon feature, the subsequent growth of an anticyclonic vorticity band towards the abyssal plain which, after becoming barotropically unstable, breaks and detaches Campeche Escarpment Eddies. The intensity of the vorticity production is related to the strength of the upstream flow. The intensification of the along-slope flow upstream of the cape is due to the confluence of abyssal circulation features, including deep cyclonic eddies, with the deep cyclonic boundary current that flows along the continental slope. The Campeche Escarpment Eddies are presumably responsible for the high eddy kinetic energy in the northern Sigsbee abyssal plain, and hence, are expected to be important in the dynamics of the deep western Gulf.',
