AtlantECO Deliverable - D06.6 - Report on the quantification, mechanisms and impacts of the carbon export in the Atlantic Ocean

Marcello Vichi, Giorgio Dall’Olmo, Tomas Lovato, Jonathan Rogerson et autres

This report explores the complexities of carbon export at the Atlantic scale, incorporating in situ observations and numerical models, with a focus on the Benguela region that was chosen as a target area for AtlantECO. A major challenge is the lack of …

Submarine Canyon Modulation of Eddy Kinetic Energy: A Seasonal Regime Shift in the Southern Benguela

Moagabo Ragoasha, Gildas Cambon, Thulwaneng Mashifane, Franck Eitel Kemgang Ghomsi et autres

Submarine canyons are recognised hotspots of enhanced vertical exchange and complex circulation, yet their role in modulating the seasonal energy cycle between mean and turbulent flows remains poorly understood. This study reveals that Cape Canyon, a major topographic feature in the Southern …

Monitoring Agulhas Current Meanders using Current and Eddy Tracking Algorithms

Sheveenah Taukoor, Annette Samuelsen, Isabelle Ansorge, Pierrick Penven et autres

Tracking meanders of the Agulhas Current and their associated cyclonic eddies is essential for understanding episodic upwelling along the southeast coast of South Africa, particularly near Port Alfred where the inshore jet interacts strongly with the shelf. We developed a new temperature-gradient-based …

Trait–Based Adjustments: Key to Improving Model Representation of the Bloom Seasonal Cycle in the Subantarctic Zone

Thulwaneng Mashifane, Alessandro Giulio Tagliabue, Sandy Thomalla

Abstract Southern Ocean phytoplankton have unique traits that allow them to survive extreme environmental conditions of low iron, light, and temperature. These traits are not well represented in Earth System Models and may lead to misrepresentation of the bloom seasonal cycle in …

BIOPERIANT12: a mesoscale-resolving coupled physics–biogeochemical model for the Southern Ocean

Nicolette Chang, Sarah Nicholson, Marcel du Plessis, Alice Lebehot et autres

We present BIOPERIANT12, a regional 1/12° ocean–ice–biogeochemical model configuration of the Southern Ocean (SO) based on the Nucleus for European Modelling of the Ocean platform. It is designed to investigate mean state, seasonal cycle, and upper ocean (< 500 m) dynamics, with …

BIOPERIANT12: a mesoscale resolving coupled physics-biogeochemical model for the Southern Ocean

Nicolette Chang, Sarah Nicholson, Marcel du Plessis, Alice Lebehot et autres

Abstract. We present BIOPERIANT12, a regional model configuration of the Southern Ocean (SO) at a mesoscale-resolving 1/12°. This is a stable, ocean–ice–biogeochemical configuration derived from the Nucleus for European Modelling of the Ocean (NEMO) modelling platform. It is specifically designed to investigate …
