Question 12

A robotic cryobot probe is deployed to explore the subglacial ocean of Jupiter's moon, Europa. The probe melts through the surface ice sheet and descends vertically through the liquid saline water ocean to reach the seafloor.

During its descent from the ice-ocean boundary to the ocean floor, the probe records the following data:

  • the increase in hydrostatic pressure is 16,500 kPa16,500\text{ kPa}16,500 kPa
  • the mean density of Europa's saline ocean is 1070 kg/m31070\text{ kg/m}^31070 kg/m3
  • the gravitational field strength of Europa is 1.31 N/kg1.31\text{ N/kg}1.31 N/kg

Calculate the depth of Europa's ocean at this location. Give your answer to 3 significant figures.
