Marine Data Model

• Presented a different kind of challenge.
• Multiple features
• Multiple depths
• Multiple Measuring devices
• Measuring multiple variables
• Example
• Moored buoy with a CTD cable with multiple
  sensors at every 10 m. At each depth one sensor
  is measuring temperature and salinity and a
  second sensor is measuring current speed and
  direction
