Frozen Food: How Glaciers Provide Food for Animals That Live in the Ocean
In this study, the scientists studied glaciers and their nearby rivers in Alaska. The water coming from glaciers can be quite old and contain nutrients, such as carbon, that could be at least 5,000 years old. The scientists wondered if the carbon in the water was too old to be useful to animals living in the rivers and bays.

About Investi-gator
The Investi-gator is another member of the Natural Inquirer family. The Natural Inquirer, for middle school students, and the Investi-gator, for upper elementary students, present science the way scientists most often share their research with each other. That process is the written scientific paper. Each Investi-gator article presents research conducted by Forest Service scientists and their cooperators. All the research in the Investi-gator is concerned with nature or with society’s relationship to nature.
