1. What is the oceanographic process?Reversal of flow direction within a significant ocean current
2. What is the primary drivers?Inertial effects, pressure gradients, Coriolis force, and bathymetric influences
3. What is a retroflect in the ocean?A retroflect is when an ocean current turns back on itself, making a loop or eddy that flows opposite to the main current.
4. Why do retroflections happen?They happen when a strong current meets a boundary like a continental shelf break, a seamount, or another current, which creates instabilities that form meanders and loops.

Fluid Dynamics: The study of fluids (liquids and gases) in motion and the forces acting upon them.
Mesoscale Eddies: Circular or swirling currents of water, typically tens to hundreds of kilometers in diameter.
Biogeochemical Cycles: The pathways by which chemical elements and compounds move through the Earth's biotic and abiotic components.
