Figure 3. Ocean current distributions in the surface layer. Vectors show the current speed and direction. Color scale also shows the current speed. (a) ROMS around Japan. For clarity, vectors are only shown over a 1/2° grid. (b) POP for the global ocean. For clarity, vectors are only shown over a 5° grid.
Figure 4. Monthly averaged surface distributions of tracer concentration (unit m−3) by ROMS at 1 unit year−1 release. The X shows the release point and the triangle shows the point of maximum concentration.
