Ocean Eddies and Marine Ecosystems

The video explores the concept of weather in oceans, focusing on ocean fronts, eddies, and gravity waves. It explains how these phenomena affect marine life, such as plankton and coral reefs. The video also promotes Arizona State University's marine science program, highlighting its focus on coastal and marine ecosystem management.

What is a key similarity between atmospheric and oceanic weather phenomena?

• Both are predictable with the same accuracy.

• Both are caused by human activities.

• Both can impact wildlife in their respective environments.

• Both involve the movement of air masses.

What is a primary characteristic of ocean fronts?

• They are static and do not move.

• They involve differences in temperature, salinity, and density.

• They are only found in tropical regions.

• They are unaffected by ocean currents.

How do ocean fronts benefit phytoplankton?

• By increasing salinity levels.

• By providing shelter from predators.

• By reducing mixing, allowing them to stay in surface waters.

• By increasing water temperature.

What is a defining feature of ocean eddies?

• They are small and short-lived.

• They are similar to atmospheric storms.

• They only occur near the equator.

• They decrease nutrient levels in the ocean.

What effect do cold core rings have on ocean water?

• They draw nutrients up from deeper water.

• They trap warm water in cold water.

• They increase water salinity.

• They cause a downwelling effect.

What opportunity does ASU's marine science program offer?

• Focus solely on atmospheric science.

• Limited access to online resources.

• In-person classes only.

• Research opportunities in Bermuda and Hawai’i.

What is the primary force behind gravity waves in the ocean?

• Human activity.

• Wind currents.

• Tidal movements.

• Gravity.

How do gravity waves help coral reefs?

• By blocking sunlight.

• By increasing water temperature.

• By bringing in cooler waters and nutrients.

• By reducing salinity levels.

What is the mixed layer in the ocean?

• A layer with no mixing.

• The deepest part of the ocean.

• A layer with constant temperature.

• The surface layer with lots of mixing.

What happens to corals during bleaching events?

• They move to deeper waters.

• They become more colorful.

• They expel algae that help them make food.

• They increase their growth rate.
