Antarctic Circumpolar Current (ACC) - fronts product
Types of dataset: Front products
DOI: 10.24400/527896/a01-2023.004 - more metadata
Contents: 3 files containing variables to monitor the position of the three main fronts of the Antarctic Circumpolar Current (ACC) - the Polar Front (PF), and the northern and southern branches of the Subantarctic Front (SAF-N and SAF-S).
Use: Ocean large-scale circulation, climate
Description: The original technique, developed by Sallée et al. (2008), assumes that iso-contours of satellite absolute dynamic topography (ADT) can be proxies for the traditional sub-surface hydrographic definition of the main Southern Ocean fronts. A recent version includes updates with the following definitions :
- Polar Front (PF) is associated with the -0.30 m ADT contour;
- Southern (main) branch of the Subantarctic Front (SAF) with the -0.10 m ADT contour;
- Northern branch of the Subantarctic Front (SAF-N) with the 0 m ADT contour.
Tool: handbook ACC fronts
Geographic coverage: Antarctic Circumpolar Current (ACC)
Distribution media: Authenticated FTP, Thredds Data Server (TDS)
