CLEAN: Pacific oyster farmers see global warming in poor harvest

The video discusses the significant mortality rates of oyster larvae in 2008 and 2009, highlighting the impact of water quality and ocean acidification. It emphasizes the unprecedented extent of water quality monitoring and the rapid rate of environmental changes that hinder organism adaptation. The video also covers pH levels in shallow water and the global impact of hatcheries, with a focus on CO2 levels. The unique aspects of current ocean acidification events are revisited, stressing the need for adaptation strategies.

What was the mortality rate of oyster larvae in 2009 at the facility?

• Over half

• 3/4

• 1/4

• All

When did the water quality changes begin to impact the larvae?

• June 15th

• August 15th

• July 15th

• September 15th

What is unique about the current ocean acidification events?

• They are limited to specific regions

• They are happening at a much faster rate

• They occur at a slower rate

• They are less severe than past events

What is the CO2 concentration mentioned in relation to shellfish larvae?

• 200 PPM

• 335 PPM

• 400 PPM

• 500 PPM

Why is the current rate of ocean acidification concerning?

• It only affects deep water

• It is too fast for organisms to adapt

• It is slower than past events

• It allows organisms to adapt

What is the pH level of the shallow water mentioned in the video?

• 8.16

• 9.0

• 7.0

• 6.5

What is the significance of the Puget Sound in the context of the video?

• It is unaffected by acidification

• It is a global hatchery

• It has the highest pH levels

• It is a local phenomenon
