Upgrade of stations

•Aim to have automated measurements with realtime transfer of data for publishing

•Higher frequency

•Less manual operationEstablishment of bottom mounted automated

profiling systems Potential for extension of parameters measured

Upgrade cont’d~

Data transfer antenna

Buoyancy, including measurement device

Sea surface Data transfer antenna

Winch

No on the shelf systems available

Challenges:

Winch/electricityData transfer
