Density = mass/ volume

• usually grams per cubic centimeter

Pure water has a density of 1.0 g/cm^3
Seawater has a density of about 1.025 g/cm^3
Gold " ~ 19.3 g/cm^3
Cement " ~ 2.7 - 3.0 g/cm^3
Chalk " ~ 1.9 - 2.8 g/cm^3
Ice " ~ .917 g/cm^3
Limestone 2.68 - 2.76 g/cm^3
Granite 2.64 - 2.76 g/cm^3 (Continents)
Basalt 2.4 - 3.1 g/cm^3 (Sea floor)

Notes: Inside labs this week - density, water

Map of Chesapeake Bay - typical distribution of surface salinity

• The lines on map are like contour lines on a normal map, but reference changes in salinity, not just height. These changes in salinity are isohalines.
• Isobaths are lines of equal length that show how salinity increases or decreases with depth.
• Iso = equal
• Bath, from bathymetry = depth of water

Happy Leap Year, folks.
That is all.

Lat = declination - altitude +90° (or)
L = D + (90-A)
You can measure the alt. of the sun off the horizon at noon w. a sextant, and look in a table for the declination of the sun. (sun's declination changes daily!)
Horizon = perpendicular to the earth radius.

Things to know:
Historical people
Geography
Tides
etc.

Things to bring:
Calculator! (but don't forget to show your work)

Hi folks. Just wanted to let you know that these notes aren't complete because I walked into class about 15 min. late because I commute and my car almost spun out twice.
~Kristen

Sorry guys! No notes for today unless someone is willing to donate theirs for submission.

In light of this situation, I do hope that someone will be able to help me with note-taking in the future.
I can't be responsible for no one having notes if for some reason I can't make it to class on any given day.
~Kristen, your desperate-for-help classroom note-taker.

Soundings: In olden days, the leadsman throws lead overboard at the right moment in front of the boat, and as the boat moves forward the lead sinks rapidly. At the moment the boat overruns the lead, it tis straight up, and the leadsman shouts out the depth. Two people with sextants watch the angles change and get the angle to the two marks. Knowing those two angles defines a point. Once the point is defined, you mark down the sounding.
You have to record the time the sounding is taken, so the soundings can all be converted to the same reference datum. You need to know what the tide is!

Will be posted as soon as I can.
Help would be appreciated.

New & Full moon - spring tides
1st & Last quarter - neap tides

The envelope of water around the Earth is always aimed towards sun or moon.

Tide Data Set, ideally 17-18 y.
There are multiple components that determine the height of a tide on any given day... astronomical, topographical, rotational
(distance Earth to moon, alignment Earth to moon, alignment Earth to sun, angle off the ecliptic, etc.)

Hi folks. Please forgive the lack of notes for Monday. As I was unable to bring my computer with me the other day, all I have is paper notes right now. Since you don't want to try and read my handwriting, I'll put them up in HTML. I still have to type them all up, format them, and do the graphics.
