The answer appears to be "no".
Going back to your original question though, you could just not fill the map.
I.e.
filled.contour(x,y,z,levels=c(2,4,6,8,10),plot.axes=map("worldHires",add=T))
Otherwise, you may have to do things the 'hard way': set up two regions, draw a
map in the
first, (here you can then use polygon to colour the ocean green, then overlay
the map
again), overlay your filled contour (perhaps again using polygon), then set up
the legend
in the other region.
Hope this helps,
