Southern Ocean
AX25
This transect, which was implemented in 2005, is used to investigate the variability in the upper layer interocean exchanges between South Africa and Antarctica on seasonal and interannual time scales by monitoring the frontal regions. It also helps to close the box formed by AX18 and AX21 to investigate the heat budget in this region with the complement of Argo observations inside the box, and to investigate the relationship between the frontal variability, its transports, and changes in the wind fields.
