1

• SOLO-II
• Design targets
• Compact, lightweight, efficient.
• Reduced labor for assembly.
• 2000 m profiles anywhere.
• Long battery life (200 cycles).
• No air bladder.
• Reciprocating pump (same as Spray glider)
• Scalable (in length, batteries, sensors).
• Pumping system adaptable for deep-ocean
  profiling.
• Prototype S-II floats are now undergoing
  lab-testing deployments soon.
