Lectures - Monday and Wednesday, 11:00 AM - 12:15 PM
Lab - Tuesday, 4:10 PM -7 PM
The purpose of this lab is for you to figure out how to drive ocean circulation. You will also determine how water masses are formed and how currents develop. This will give you insights into the nature of ocean circulation. This lab exercise differs from previous labs because you will decide which materials and methods to use.
We will provide you with an aquarium where you will simulate ocean circulation. Get together in small groups and decide which materials you will need to complete the following tasks:
Both goals may be accomplished simultaneously.
Sketch and describe what is happening in the aquarium at each step along the way. Sketch the vertical cross section of the flow in the tank. Label the temperature/salt content and the flow direction in each layer. Measure the depths of the thermocline and halocline and label them in the appropriate sketches.
Calculate the horizontal and vertical velocities in each of the three different cases. Include these numbers in your lab report.
Considering what you know already about the Earth's climate, and what you have seen today in lab, incorporate the answers to these questions in your lab report:
Write a lab report (as per the Lab Report Format) summarizing the major findings of your investigation.
