CLEAN : Drifting into trouble? The tiny ocean creatures with a global impact

The video tutorial discusses the observation of phytoplankton under a microscope, highlighting the importance of long-term data in understanding oceanic trends over decades. It emphasizes the impact of global warming on plankton, particularly zooplankton, affecting their seasonality, nutritional quality, and distribution, which in turn influences fish populations.

What can be observed under a microscope in water samples?

• Only bacteria

• Various species of plankton

• Only zooplankton

• Only phytoplankton

What is the significance of observing phytoplankton coloration in water samples?

• It indicates water pollution

• It helps identify the presence of phytoplankton

• It shows the water temperature

• It reveals the water's salinity

Why is long-term data collection crucial in ocean studies?

• To monitor tidal waves

• To track trends in ocean warming and acidity

• To observe short-term weather changes

• To measure daily fish populations

What is one of the key impacts of ocean acidity changes?

• More frequent hurricanes

• Changes in food webs

• Increased rainfall

• Higher fish reproduction rates

How does global warming affect zooplankton?

• It makes them grow larger

• It changes their seasonality and nutritional quality

• It has no effect on them

• It causes them to become extinct

What is a consequence of zooplankton shifting out of their normal ranges?

• Decreased fish populations

• Increased fish populations

• Fish migrate to land

• No impact on fish

What is the primary focus of the surveys conducted in the area?

• To track bird migration

• To count the number of ships

• To understand the local marine environment

• To measure air pollution
