SummaryWhat we know so far . . .
Prototype device still in service.Hardware costs less than expected. ($4,000)Power consumption higher than expected.Real-time data transmission and whole water column sampling systems robust.YSI Data Sonde the weak link . . .The platform provides users the ability to remotely troubleshootproblems with the sonde.May need to consider building an additional device used for all sonde deployments:
Simple communication device Facilitate remote dialog with data sondesAllows for remote troubleshooting
