Research ship embarks on expedition to study the distribution of microplastics in the ocean and impact on plankton

The video discusses a mission by the National Oceanography Centre to study microplastics in the Atlantic Ocean. Microplastics, originating from various sources, pose a threat to marine ecosystems. The mission involves deploying equipment to different ocean depths to measure microplastic levels. The video highlights the vast scale of the microplastics problem, with trillions of pieces in the ocean, and the mismatch between released and found microplastics. The mission aims to provide insights into how deep microplastics penetrate the ocean and their environmental impact.

What are microplastics and how do they enter the ocean?

• Metal fragments from ships

• Natural particles found in the ocean

• Tiny plastic fragments from various sources like clothes and bottles

• Large pieces of plastic that break down in the ocean

What is the primary objective of the National Oceanography Centre's mission?

• To explore marine life

• To clean up the ocean

• To investigate the presence of microplastics at different ocean depths

• To study the impact of climate change

How long is the rope used in the mission to study microplastics?

• 1500 meters

• 4800 meters

• 3000 meters

• 6000 meters

What percentage of ocean rubbish is plastic?

• 50%

• 75%

• 95%

• 100%

What is one of the major challenges in understanding microplastics in the ocean?

• No interest in microplastic research

• Lack of technology to detect microplastics

• Mismatch between released and found microplastics

• Inability to measure ocean depth
