Fig. 7. Cumulative sum regression (Naugolnykh et al., 1998a).

Fig. 8. Current profile retrieval by means of small aperture tomography scheme (15×200 km²). The darker of the ambiguity area - the higher probability for the current velocity V at the given distance r. Solid line shows the initial current profile typical for the Fram Strait cross-section on 79°N from 6°E to 4°W (East is on left). Positive current velocity corresponds to direction to North (Naugolnykh et al., 1998b).
