Update from the ship's librarian, Laurel.
7/17/2014
We are now staring into the mouth of Baltic Sea,
somewhere between Germany and Denmark. With lower salt content than many other
oceans, the Baltic has sometimes been seen as one big river mouth which often
gets covered with ice in the winter.
Fortunately, it’s quite warm now with very sunny
conditions for those on watch at the weather deck to lookout for other vessels
and for those of us on break to scan for porpoises and chat.
I’ve been trying to learn a little bit more about how
this ship gets from point a to b, and the cadets have been very happy to
demonstrate the use of various kinds of instruments and computer equipment
that’s required. So far I can understand just one thing clearly, which is that
navigation is complicated business.
Hanging out in the aft chart room, a young lady mug
explains to me that looks can be deceiving – the maps on the wall are
apparently not “maps” at all, but are instead known as charts, which reveal key
information such as ocean depth, currents, shoals, rocks, and other obstacles
using various symbols. We talk a little about what I still refer to as “maps”
as she shows me what she is up to on “ECTIS” – the “electronic chart display
information system” that is used for paperless navigation.
The chart room is always one of the busiest places on the
ship – full of cadets measuring the angles of the sun or the stars, finding the
variation between true and magnetic north, examining our progress on charts of
varying scales for various purposes, plotting our course based on way points
and compass bearings, and doing what amounts to some very complicated math.
(Thanks to instructors Lou Muno and Rick Martucci for helping me understand the
tiniest fraction of what I’m looking at, but I think I will leave all the
navigation business to the hardworking cadets!)
Shout out: Zac Curtis, Ist classman, says “Hi Mom and
Dad! Finally made it to the library to study ! Love you!”
