Why Observe?: Tree Height

The video explores the challenges and methods of measuring ice thickness and tree height using IceSat-2. It highlights the importance of these measurements for understanding Earth's systems, such as carbon storage and ecosystem health. The role of algorithms in processing satellite data and the significance of citizen science in contributing to scientific research are also discussed.

What challenges are faced when conducting research on ice flows?

• Insufficient satellite data

• Too many polar bears

• Lack of suitable ice thickness

• Excessive warmth on the ship

What is the primary purpose of the ICESat-2 satellite?

• To monitor global temperatures

• To measure ice thickness and tree heights

• To track polar bear movements

• To measure ocean currents

Why is it important to use different methods to measure the same environmental feature?

• To increase the number of satellites

• To reduce research costs

• To ensure accuracy and reliability

• To confuse the data

What is one method used by students to estimate tree height?

• Using a thermometer

• Using trigonometry with a clinometer

• Using a compass

• Using a barometer

How do tree height measurements contribute to understanding Earth's carbon cycle?

• They indicate the amount of carbon stored in forests

• They measure the temperature of the forest

• They show the age of the trees

• They help track animal populations

Why is structural diversity in forests important?

• It provides habitat for various animals

• It increases the forest's temperature

• It reduces the number of tree species

• It makes the forest easier to navigate

What is a significant benefit of adding height data to satellite images?

• It increases the resolution of the images

• It reduces the cost of satellite missions

• It allows for better understanding of forest structure

• It makes the images more colorful

What role do citizen scientists play in environmental research?

• They replace professional scientists

• They provide additional data from various ecosystems

• They fund the research projects

• They design the satellite instruments

How do citizen scientists help in monitoring environmental changes?

• By predicting weather patterns

• By designing new algorithms

• By collecting data on the ground

• By providing funding for satellites

What is the main reason for involving the community in scientific research?

• To reduce the workload of scientists

• To increase public awareness and data collection

• To decrease the cost of research

• To replace professional researchers
