Origin and evolution of giant comet marks along the North Atlantic Deep-Water flow on the Demerara plateau

Paul Blin, Lies Loncke, Xavier Durrieu de Madron, Sébastien Zaragosi, Kelly Fauquembergue, Swanne Gontharet, Ivane Pairaud, Pauline Dupont, Sandrine Caquineau, Bruno Charriere, Raphael Lagarde, Christophe Basile

The Demerara Plateau, located in the equatorial Atlantic, is particularly well-suited for recording the activity of the Deep Western Boundary Current (DWBC), which transports North Atlantic Deep Water (NADW) southward into the Atlantic basin. This current, active between 1500 and 3500 m depth,…

Mechanisms driving mesoscale latent heat flux variations and mixed layer heat content evaluation in the Northwest Tropical Atlantic

Pablo Fernández, Sabrina Speich, Guillaume Lapeyre, Claudia Pasquero, Carlos Conejero, Lionel Renault, Fabien Desbiolles

In this study, a high-resolution ocean-atmosphere coupled simulation is used to assess the effects of sea surface temperature (SST), surface currents, and ocean vertical stratification on the spatial variability of latent heat flux (LHF) and the stability of the marine atmospheric boundary layer (…

Oceanic δ¹³ C Fingerprints Caused by Laurentice Ice Sheet Discharges: Model‐Data Comparison During Heinrich Event 4

Louise Abot, Claire Waelbroeck, Aurélien Quiquet, Nathaelle Bouttes

Abstract This study investigates the sensitivity of the oceanic circulation and of the dissolved inorganic carbon to ice discharge events from the Laurentide ice sheet (LIS), using an isotope‐enabled and coupled climate–ice sheet model, and observations. The ice discharges are triggered by either…
