The Motion of a Neutral Float and Attached Diaphragm in a Pressure Gradient.
Abstract
A float that is neutrally buoyant at a fixed depth in the ocean can serve as a platform for making measurements. If the float has physical properties that are identical with those of water, a study of its motion would reveal the motion of the water. Measurements of this nature would differ from those obtained at a fixed point in space. The instruments themselves would be on an accelerating reference frame, and the meaning of their readings may not be obvious. A hydrophone inside an accelerating float could indicate pressures which do not exist. Again, no pressure fluctuations would be found under gravity waves. The purpose of this note is to study the response of both a float and an attached device for measuring pressure gradients. Even though the particular device is of limited interest, the study of the response of the system to oceanic motions has some fascinating features. (Author)
