SOLO-II Design
SOLO-II is the current Argo float model produced by IDG and its design is the result of decades of development, dating back to 1990s with the development of the Autonomous Lagrangian Circulation Explorer (ALACE) float. With a high performance pump attached to an external bladder, these robots change their buoyancy to dive down to 2000 m and then return to the surface profiling the water column. After each cycle, the collected data are transmitted through a satellite link to IDG and then passed to the Argo Data Center.
