Bathymetry In Action
Bathymetry is the study of the contour of the land underneath bodies of water and shows variations in the seafloor and lake floor depth
similar to topographic maps on land.

Student Activity
Mapping the Ocean Floor
Hydrographic Surveying: Mapping the sea floor Hydrographic surveying is a scientific career that many people may not know about. In this activity, a sealed shoe box with a varied topography made out of clay will be measured by taking depth “soundings” with a skewer.

Ocean In Motion
Ocean Motion: Wind-driven currents
Model the flow of ocean surface currents by blowing air across a tub of rheoscopic fluid and water, with clay structures simulating coastlines, islands, and seafloor features.
Collecting Data: CO2
Students will think about how NOAA measures carbon dioxide

Effect of Solar Wind on the Geomagnetic Field
To monitor changes in the earth’s magnetic field and relate these changes to solar events such as
flares. Many variations of this design are in use by amateurs because of its simplicity, but now with the availability of inexpensive and sensitive Hall-effect sensors that easily interface to home computers, it should be possible to make more quantitative measurements of changes in the geomagnetic field due to solar wind. By monitoring changes in the geomagnetic field, aurorae and related effects can be forecast and studied.

Measuring the Solar Constant
With this activity, we will let solar radiation raise the temperature of a measured quantity of water. From the observation of how much time is required for the temperature change, we can calculate the amount of energy absorbed by the water and then relate this to the energy output of the Sun.
