Figure 3 : Difference between the time mean surface current at 5m depth with and without the assimilation of the seabird drift in the 2010 season (a), the seabird drift in the 2011 season, and the ship drift in the 2014 season (c).

From: Assimilation of the seabird and ship drift data in the north-eastern sea of Japan into an operational ocean nowcast/forecast system

Figure 3

Difference with magnitude smaller than 0.05 m s−1 is not shown. The composite drift data are represented by the blue colored vectors. The arrow length scale for the difference is doubled as compared to that for the drift. Numerics at the top of the figure denote the period. These figures were created by using the Grid Analysis and Display System (GrADS) Version 2.0.
