text: In order to fully understand complex ocean systems, a wide variety of sensor arrays, capable of surviving for long periods of time in harsh conditions, are necessary.  A suite of sensors (over 100) were selected and strategically placed throughout RSN.  They are located at Axial Seamount, Hydrate Ridge, and also on the water-column moorings.
  Instruments connected to the RSN include:  
  *  Conductivity Temperature Depth (located on profilers)
  *  Dissolved Oxygen, 
  *  3-D Single Point Current Meter 
  *  Temperature
  *  Fluorometers 
  *  CDOM, 
  *  Chlorophyll-a, 
  *  Optical Backscatter
  The instruments are the final spot of each regional network branch.
