Swot effectively captures the presence of seiche-like structures in French Polynesia lagoons

Category: News of the Swot mission

An article published on the detection by Swot of seiche-like structures in French Polynesia lagoons

A study describes the spatial structure of low amplitude oscillations, known as seiches, in the lagoons of several atolls in the French Polynesia this time. This ability to detect seiche-like structures in small bodies of water (less than 80 km in length) opens up new avenues of research into these events and their contribution to erosion and flooding in remote locations.

See a presentation of the results on Swot Adac web site by T. Ballerini.
