Activity 2: Inspecting the craters of active volcanoes. Volcanoes are hazardous environments for humans due to heat, toxic gases, and unpredictable eruptions. Drones can be flown into volcanic craters to collect visual data, thermal imagery, and atmospheric gas samples, providing valuable information for monitoring and research without putting scientists at risk. This is a demonstrated application of drones. Correct.
Activity 3: Collecting breath samples from spouting whales for DNA analysis. Researchers use drones to fly over whales and collect samples of the “snot” (exhaled breath and mucus) from their blowholes using collection plates attached to the drone. These samples contain DNA, hormones, and microbiome data, which are crucial for studying whale health and populations. This is a less invasive method compared to traditional biopsy darts and is successfully being used in marine biology. Correct.
