Activity #4: Graphing Rumbleometer Data

The rumbleometer was stuck in the new lava flow, but amazingly, it survived. During your dive, ROPOS attached a cable to the rumbleometer and the ship was able to pull it free from the lava and recover it at the surface.
You can now examine the data that the instrument recorded! The water temperature and pressure were measured continuously during the eruption of the lava flow. Pressure can be easily converted to depth and we can determine if there was any upward or downward movement of the instrument during the eruption. By examining the temperature and pressure changes you may be able to tell exactly when the eruption began and how long it lasted.
