neat. Maybe change the color rule to move ocean -> black down to 5-8 km
instead of 500m? (that color scale was designed for showing detail in
the coastal shelf)
For finer-grained circle sizes, with ps.map you can use the sizecol
option with the vpoints command. Or d.vect.chart can do this, or
'v.buffer bufcol='.
maybe better to plot circles as e^boom as it's based on a log scale?

ps - I know one of those circles quite well. :)
