S2-A, and expanded its product line to include an ‘A’-size pro? ling ? oat, the Air Launched Autonomous Micro-

Observer (ALAMO). MRV’s ? agship product is the S2-A, a re? nement of the

SOLO II design originally licensed from the Scripps Institution of Oceanography.

The S2-A is a buoyancy-driven vertical pro? ler, capable of operating to 2,000m depth. It typically carries a Conductiv- ity-Temperature-Depth sensor to obtain vertical pro? les from 2,000m to near the surface. To meet the needs of more rigorous environmental deployment conditions, MRV developed, built, and deployed a smaller vertically pro? ling ? oat. The ALAMO is an ‘A’-sized air- deployable pro? ling ? oat meant to pro- vide the same performance as the MRV

S2-A, but in a smaller package. The AL-

AMO has been successfully launched each year to date since the 2014 hurri- Liquid Robotics cane season.
