Impact of Wind on Ocean Dynamics

The video explains ocean temperature fluctuations caused by upwelling and downwelling, driven by wind patterns and the Coriolis effect. It covers Ekman transport, mesoscale eddies, and their impact on ocean circulation. The video also discusses the economic significance of these phenomena, particularly in fisheries, and their influence on global climate patterns.

What causes the fluctuations in ocean temperatures at the Jersey Shore?

• Seasonal changes

• Global warming

• Upwelling and downwelling

• Tidal waves

In the northern hemisphere, how does the Coriolis effect influence water movement?

• Water spirals upwards

• Water moves in a straight line

• Water deflects 90 degrees to the right

• Water deflects 90 degrees to the left

What happens to water when winds push it away from the coast?

• Water remains stagnant

• Coastal upwelling occurs

• Water temperature increases

• Coastal downwelling occurs

What is Ekman transport?

• Horizontal movement of water due to wind stress

• Vertical movement of water

• Temperature-induced water movement

• Circular movement of water

What are mesoscale eddies?

• Small ocean circulations influenced by temperature gradients

• Deep ocean trenches

• Small atmospheric circulations

• Large ocean currents

How does the curvature of the coast affect upwelling and downwelling?

• It reverses the effect

• It maximizes the effect

• It minimizes the effect

• It has no effect

During an El Niño event, what occurs along the eastern Pacific coast of South America?

• Upwelling

• Increased salinity

• Downwelling

• No change

What impact does upwelling have on ocean water clarity?

• Increases clarity

• Decreases clarity

• No impact

• Increases salinity

Why is the Peruvian anchovy fishery significant?

• It is the largest fishery in the world

• It is located in the northern hemisphere

• It relies on coastal upwelling

• It is unaffected by upwelling

How does wind direction impact the fishing industry?

• It only affects tourism

• It has no impact

• It affects fish migration patterns

• It influences upwelling and downwelling, impacting fish populations
