VMP250 upriser

Data set: Fer et al. (2022): Under-ice temperature and dissipation rate profiles from uprising VMP250 during MOSAiC., PANGAEA.

A battery-powered VMP250 internal recording, configured to be positively buoyant (uprising), by installing a flotation collar close to the front bulkhead of the instrument. Brushes at the tail provided drag to adjust to the desired rise speed.

Data channels:

• Temperature
• Micro-conductivity
• Dissipation rate of turbulent kinetic energy \varepsilon
