wonders of a navigation chart

[nibot]

I'm still not quite adequately informed about the band structure of semiconductors, but before I go to sleep for a bit I have to mention this nautical chart that's on the wall in the study room. Accurate, up-to-date, waterproof, and comprehensive, this "chart, map, & guide" to the San Francisco Bay [and?] Golden Gate is really quite nifty. It's basically a topographic map of the bottom of the bay and is a key to an otherwise unseen geography. For instance, the shipping lane through the Golden Gate is actually rather narrow but 51.9 feet deep. Off to the side is indicated the area where they dump the dredged channel material, and on the other side there is the "Four Fathom Bank" and the "Potatopatch Shoal." The ruins (what is the story, anyway?) of the Berkeley Pier (which goes nearly to Treasure Island) are clearly illustrated; the pier was possible because this whole bay centered on the Berkeley Marina is only nine feet deep. It's also interesting to see all the special channels (as separates Alameda from Oakland) and weird mooring areas ("Anchorage for Explosives, No. 12"). I suppose it takes a certain kind of person to find that fascinating. This is also further evidence of the coolness of JennyJo, as she is the one who put this nifty chart up on the wall. Too bad I never managed to tomsawyer the Sacramento.

what more could you possibly need to know than this (http://www.cs.wisc.edu/~kovar/hall.html)?!

a topographic map of the bottom of the bay = bathymetric map

I had to know this too (http://britneyspears.ac/lasers.htm)!

I did know that.. but I like "topographic map of the bottom of the bay" better! (-:
