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

The video explores the research on plankton in the southeast of England, focusing on the use of Continuous Plankton Recorders (CPR) to collect samples. It highlights the importance of plankton in the ocean ecosystem, their role in oxygen production, and their response to climate change. The video discusses the historical data collected over 90 years, showing trends in ocean warming and acidity. It also addresses the movement of plankton due to global warming and the potential impact on marine life, with predictions of a decline in phytoplankton populations.

What tool do scientists use to collect samples of microscopic life underwater?

• A continuous plankton recorder (CPR)

• A zooplankton trap

• A marine microscope

• A phytoplankton net

How long have CPR machines been used to study the oceans?

• 120 years

• 90 years

• 60 years

• 30 years

What are the two main types of plankton?

• Phytoplankton and zooplankton

• Algae and krill

• Fish larvae and crabs

• Marine plants and animals

What role do phytoplankton play in the global ecosystem?

• They are responsible for ocean currents

• They regulate ocean temperatures

• They are the primary food source for whales

• They produce nearly half of the world's oxygen

What is a predicted consequence of climate change on plankton populations?

• A stabilization of plankton populations

• An increase in plankton diversity

• A rise in plankton nutritional quality

• A shift towards cooler areas
