ESM120 Eutrophication Presentation

According to Diaz in 2009, what is the approximate extent of dead zones across the globe?

Which is a major human source of eutrophication-causing nutrients?

Oxygen depletion in marine ecosystems occurs only on a seasonal basis.

Which water basin experienced complete eutrophication in the last 50 years?

Hypoxia is a reduced presence of dissolved oxygen in water, while anoxia is a complete depletion of dissolved oxygen.

Partial recovery of dead zones means we have fixed the environment and can stop restoration efforts.

Hypoxia occurs when there are low concentrations of dissolved oxygen in the ocean.

How can climate change affect eutrophication processes?

What effect can cyanobacteria have on humans?

Which area of California is experiencing eutrophication?

Where do dead zones typically form?

Which practice can help to reduce eutrophication and dead zones?

What is the first sign of eutrophication in a marine ecosystem?

What occurs when algae die and decompose?
