Hydrosphere
What is the condition of Earth’s many surface waters—the streams, rivers, lakes, and coastal waters? How do these conditions vary over the year? Are these conditions changing from year to year?
Through the GLOBE Hydrosphere investigation you can help address these questions by monitoring the waters near your school. Our knowledge of global trends in water measurements is based on sampling at very few sites. This sampling has generally been done only a few times. For example, our information on many lakes is based on sampling done only once or twice more than ten years ago.
