For 21 of those years, the ERBS actively investigated how the Earth absorbed and radiated energy from the Sun, and made measurements of stratospheric ozone, water vapor, nitrogen dioxide, and aerosols.

Deep beneath the waves, tiny clams with shells usually about as big as a pea bore into pieces of sunken wood. The wood is food for them, as well as a home. These rare, scattered, sunken pieces of wood support miniature ecosystems where different wood-boring clam species can live in harmony for years. But in […]
