Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the spectral resolution?Acquires data in tens to hundreds of contiguous, narrow spectral bands
2. What is the data structure?Forms a data cube with spatial and spectral dimensions
3. What is a hyperspectral imager and how does it help us see the ocean?It is a special camera that captures many very narrow color bands, letting scientists see details like different types of algae and pollutants that are invisible to the eye.
4. Why do scientists use drones or satellites to carry hyperspectral imagers?Drones give high detail for specific spots, while satellites cover large areas to track long‑term changes in the ocean.

Spectral Resolution: The ability of a sensor to distinguish between different wavelengths of light.
Spectral Reflectance: The proportion of incident light that a surface reflects at specific wavelengths.
Harmful Algal Blooms (HABs): Rapid increases in algae populations that can produce toxins harmful to marine life and humans.
