Adjusted Sea Level Anomaly (ASLA): The altimeter data is shown as coloured circles surrounding black dots along the tracks of the altimeters, superimposed on our interpolated field (legacy name: Gridded Sea Level Anomaly). The colourbar shown applies to both.

○ Argo: pink circle at the location of any profile made in the window t0 +/- 12hrs; click on the circle to see the Argo profiles of temperature and salinity.

> Drifter: 6 hourly Global Drifter Program surface drifter (drogued at 15m on deployment) within a window of -2 to +1 day around t0. Location and velocity are indicated with pink arrow heads.

Selected isobaths: grey and cyan contours, in metres.

The latest ASLA (NRT00) map is usually dated 4 days behind real time, as indicated.
