Jason-2 plays roller-coaster in the Algulhas retroflection eddies

Category: News of the Jason-2 mission

Jason-2 measured some quite impressive sea level anomalies South of Africa -more than 2 m between high and low. If such heights, corresponding to eddies in a very turbulent region are not absolutely extraordinary, they are still interesting to look at -- and to compare with other satellites.

Jason-2 Sea Level Anomalies for Track 183.

The Algulhas retroflection is a turn of the current South of Africa, where the current make a sharp about turn. Jason-2 observed some quite high Sea level anomalies in the region, which were also seen by GFO, among others (Jason-1 was in Safehold mode at that time).
