Hanks also picked u bathymetry data <br /> sheets for Ockway Bay, Shoestring Bay and Pop' onesset Bay , but <br /> Bayne plotted these sheets � .. i <br /> using "northings s and eastings instead <br /> of lattitude and longitude , so we cannot easily sly but the whole <br /> eitiba yment together. we will try to catch Wayne in <br /> jobs to provide�.de between �.red�e <br /> more charts . e also want to superimpose the <br /> contour maps on the digitized USGS topographic maps .
