Gulf of Mexico ocean dynamics and its modulation by air-sea interactions
At basin-scale, it has been recognized for several decades that interactions between the ocean and the atmosphere have a major influence on the Earth's climate. However, persistent biases in global models, for example in sea surface temperature, have highlighted the limitations of a global appr...

At basin-scale, it has been recognized for several decades that interactions between the ocean and the atmosphere have a major influence on the Earth's climate. However, persistent biases in global models, for example in sea surface temperature, have highlighted the limitations of a global approach at relatively low spatial resolution. This led to a new line of research based on a regional approach to ocean dynamics and ocean-atmosphere interactions. This thesis is part of this approach by focusing on the Gulf of Mexico (GoM). The (GoM) is part of the western boundary current system of the North Atlantic. It represents a complex system where human activities, such as oil extraction and fishing, interact extensively with the ocean environment and biogeochemical ecosystems. The dynamics of the GoM are dominated by the emblematic Loop Current (LC), an intense anticyclonic current that brings warm Caribbean waters into the GoM. The LC episodically sheds warm core an- ticyclonic eddies that propagate westward: the Loop Current Eddies (LCEs).
