# load NW Atlantic data and convert to class bathy
data(nw.atlantic,nw.atlantic.coast)
atl <- as.bathy(nw.atlantic)

## the function plot below plots only isobaths:
## - isobaths between 8000-4000 in light grey, 
## - isobaths between 4000-500 in dark grey (to emphasize seamounts)

plot(atl, deep=c(-8000,-4000), shallow=c(-4000,-500), step=c(500,500), 
 	 lwd=c(0.5,0.5,1.5),lty=c(1,1,1),
 	 col=c("grey80", "grey20", "blue"), 
 	 drawlabels=c(FALSE,FALSE,FALSE) )
 	 
## the coastline can be added from a different source, 
## and can therefore have a different resolution:
lines(nw.atlantic.coast)

## add a geographical reference on the coast:
points(-71.064,42.358, pch=19); text(-71.064,42.358,"Boston", adj=c(1.2,0))
