Activity 3 - Surface Ocean Circulation


Use the resources listed below to help you complete this activity.

 

To learn more about this topic, visit the following web sites:


Surface Currents

Using flotsam to study ocean currents - NASA
This article contains information regarding the spill of shoes and rubber duckies in the Pacific that students investigate in Activity 3, specifically how the spill led to a greater understanding of ocean circulation patterns.

Ocean Currents and Climate - USC
Topics covered include the effect of wind stress on the water surface, the impact of the Coriolis effect on surface current patterns, and continent interference. Includes text and images to explain the major ocean gyres, transverse currents, western and eastern boundary, and the effect of plate tectonics on surface circulation.

Upwelling

"Underwater Observatory Captures Coastal Upwelling Off New Jersey" - Glenn et al., 1996, Earth in Space, v. 9, no. 2, pp. 9-11, AGU
Online article illustrates how scientists study upwelling by presenting findings on upwelling along the East coast of the United States (New Jersey). Includes images and a glossary for unfamiliar terms.

To learn more about the relationship between surface currents and climate, visit the following web sites:

"What is Climate?" - TOPEX/Poseidon, Jet Propulsion Lab, NASA
First window defines climate. After reading text, click on link at bottom of screen to cover topics that include the connection between the oceans and atmosphere, what ocean circulation is and why it is important, and the seasons of the oceans. Several of the windows have color images.

Gulf Stream Temperatures - NASA's Visible Earth
Explains this ocean current, which plays an extremely important role in regulating global climate. Includes a high-resolution satellite image.
