Greenland A Laboratory For The Symptoms Of Global Warming

The video discusses a plan to use a helicopter to survey ice stations, where instruments measure ice speed and position. This data helps understand how temperature affects ice flow and lake drainage. The team collects data each summer and maintains equipment due to rapid ice melting.

What is the primary purpose of the helicopter trip mentioned in the video?

• To rescue stranded researchers

• To transport equipment to a new research site

• To visit stations around lakes on the ice sheet

• To conduct aerial photography of the ice sheet

How do the instruments at the stations help researchers?

• By tracking wildlife movements

• By predicting future weather patterns

• By measuring the thickness of the ice

• By precisely measuring the speed of the ice

What kind of data do the instruments provide every 15 seconds?

• Temperature readings

• Ice position data

• Snowfall amounts

• Wind speed measurements

Why is it important to understand how cracks under lakes open and drain?

• To improve fishing techniques

• To predict ice sheet collapse

• To understand ice response to lake drainage

• To measure water quality

Why do researchers need to adjust the instruments each summer?

• To change the batteries

• To avoid interference from wildlife

• To upgrade the technology

• Because the ice melts rapidly, lowering the surface
