This example is similar to ../democd5/dive_nc.htm but in this one I add
the ocean floor depth contour data as annotated shades of blue, using the
same annotate techniques as I used in ../democd13/bay.htm.
You can go back and read their detailed descriptions if you want
to know exactly how the code works :)
Three versions:
../democd5/dive_nc.htm
../democd26/nc_scuba.htm
../ods14/scuba_diving_locations_in_nc.htm

Here's how I got the ocean-floor data ...
(this might not be exact, but something close)
http://www.ngdc.noaa.gov/mgg/gdas/gd_designagrid.html
Your Grid Id: bobsas1
Grid Database: ETOPO2 - 2-minute global relief
x - Windows
Lat/Lon (left defaults - lat(up/down) = 36.5N-33N , lon (across)=79W-75W
Cell size - 2-minute (then it switched to 3-minute)
Cell params - default (2-byte integers, whole meters precision)
Format: XYZ (lon,dat,depth), No Header, Space delimited, omit empty grid cells
Clicked 'Design-A-Grid' button.
Clicked 'Next-->' button

Clicked 'save'
Saved bobsas1_5772.zip to my U:
Then, after saving it, I unzipped it, which created a directory structure...
There's a lot of 'junk', but the file I wanted was ...
/u/realliso/bobsas1_data/bobsas1/bobsas1_5772.xyz
