The Bathythermograph

The Bathythermograph

Detailed Description

The mechanical bathythermograph was invented as a tool to understand the temperature layers of the ocean. The torpedo-shaped device was attached to a long cord and dropped off the side of a boat. As it sunk towards the sea floor, an internal needle scratched a line on a piece of glass that represented temperature relative to water depth.
