This work presents new evidence for conducive conditions for the existence of overturning instabilities in the mixed layer across a mesoscale anticyclonic Loop Current Eddy (LCE) and surrounding cyclonic eddies in the Gulf of Mexico (GoM). The LCE was intensively sampled using four gliders during 12 months. The LCE is characterized by a strong anom...

This study investigates the vertical structure of the dynamical properties of a warm-core ring in the Gulf of Mexico (Loop Current ring) using glider observations. We introduce a new method to correct the glider’s along-track coordinate, which is, in general, biased by the unsteady relative movements of the glider and the eddy, yielding large error...

The pattern of zooplankton migration has been investigated in the water column from 120 to 1300m depth using the backscatter strength signal (Sv) provided by Acoustic Doppler Current Profilers (operating at 300kHz and 76.8kHz), from a 10-year high-frequency mooring time series (2008–2018) in the deepwater region of the western Gulf of Mexico (GoM)....

El objetivo del presente trabajo es comparar las mediciones de la velocidad superficial obtenidas por planeadores submarinos autónomos (PSAs) con las velocidades estimadas de las posiciones geográficas (PGs) de PSAs cuando se encuentran derivando superficialmente en las aguas profundas del Golfo de México. Se utilizaron en particular los datos del...

The erosion of the subsurface salinity maximum, signature of the Caribbean Subtropical UnderWater (SUW), within the Loop Current Eddy (LCE) Poseidon (August 2016 to July 2017) in the Gulf of Mexico (GoM) and the formation of the Gulf Common Water (GCW) during its journey westward, was observed using glider data. Most of the dilution of the SUW high...

The upper layer of Loop Current Eddies (LCEs) in the Gulf of Mexico (GoM) can be perceived as a large bulge of nearly homogeneous water or pycnostat separated by a double thermocline. Mixed-layer depth is shallow (∼ 30m) in summer and deep (∼ 150m) in winter. Submesoscale variability arises in the form of filaments or fronts in regions of straining...

In this study, we harness the 25-year satellite-altimeter record, in concert with a vast array of in situ measurements, to estimate the heat content anomaly of 32 warm-core rings in the Gulf of Mexico (GoM). The decay rate of these mesoscale eddies is studied in detail, and it is shown that they release the majority of their heat as they drift in t...

Article
Recent glider observations in the Gulf of Mexico revealed the fine-vertical scale thermohaline structure of a Loop Current Eddy (LCE). Partially compensating temperature and salinity anomalies are shown to organize as thin layers below the eddy and at its periphery. They have vertical scales ranging from 2 to 60 m and have a large lateral coherence...

Four years (09/2012 to 08/2016) of simultaneous current observations across the Yucatan Channel (@ ~21.5° N) and the Straits of Florida (@ ~81° W) have permitted to investigate the characteristics of the flow through the Gulf of Mexico. The average transport in both channels is 27.6 Sv (1 Sv = 106 m3/s), in accordance with previous estimates (Schmi...

The vertical structure of a recently detached Loop Current Eddy (LCE) is studied using in situ data collected with an underwater glider from August to November 2016. Altimetry and Argo data are analyzed to discuss the context of the eddy shedding and evolution as well as the origin and transformation of its thermohaline properties. The LCE appeared...

This study describes in detail the water masses of the Gulf of Mexico (GoM) west of 88 based on their thermohaline properties and dissolved oxygen concentration. The existent historical information is complemented with new data from 14 cruises, Argo floats and over one year of continuous glider monitoring. The results describe the general hydrograp...

High-resolution hydrographic measurements reveal the presence of three intrathermocline eddies (ITEs) embedded within a loop current eddy. ITEs are lenticular bodies of nearly homogeneous water, which contrasts with the well-stratified surrounding water. Their radii and thickness ranged between 19–32 km and 150–250 m. Negative relative vorticity wi...
Article
The coupling between the upper (z < 1000-m depth) and deep (z > 1500 m) circulation in the western Gulf of Mexico (WGoM) driven by the arrival of Loop Current eddies (LCEs) is analyzed from moorings measuring horizontal velocity in the full water column during a 5-yr period (October 2008-October 2013). Nine LCEs crossing the mooring array are docum...

The self-organization of confined, quasi-two-dimensional turbulent flows in a rotating square container with a step-like topography is investigated by means of laboratory experiments and numerical simulations based on a rigid lid, shallow-water formulation. The domain is divided by a bottom discontinuity into two rectangular regions, one being shal...

Decaying, quasi-two-dimensional turbulent flows in a rotating rectangular domain with a step-like topography are investigated by means of laboratory experiments and numerical simulations. The aim is to describe the role of a discontinuous topography on the evolution and organization of the vortices. Initially, vortex interactions lead to the self-o...
Conference Paper
Decaying turbulent flows with topography are studied by means of laboratory experiments in a rotating tank and by numerical simulations based on a quasi-two-dimensional model. The basic configuration is a step-like topography dividing the flow domain in deep and shallow regions. The main objectives are: to prove that different domain geometries inf...

The interaction of a barotropic, dipolar vortex with a step-like topography is studied by means of laboratory experiments in a rotating tank and by numerical simulations based on a quasi-two-dimensional model. Two main configurations are analyzed: when the dipole approaches a “low” or a “high” step with respect to the maximum water depth. For relat...
