Drift bottle, type used from 1890-1960, for studying ocean surface currents.

For thousands of years, people have used the movements of objects floating on the surface of the ocean as a way of understanding ocean currents. Bottles like this were adopted by scientists in the 1800s, who would release them into the sea in known locations. They carried a message inside encouraging anyone who found them to break the glass, so that information could be reported back to the researchers.
