Activates or deactivates recovery mode. no
The rate of ascent in decibars per second that the float attempts to maintain. During the ascent the float measures its actual ascent rate, and if it is less than AscentRate, the buoyancy position is moved in accordance with BuoyancyNudge. 0.08
The interval in seconds between float samples of the pressure to check the ascent rate and to determine if the surface has been reached. 60
The interval in seconds between float samples of the pressure to determine if the Profile depth has been reached. 300
The interval in seconds between which the float attempts to communicate over the Iridium satellite network. 3600
The period in days over which the float avoids the surface due to the possible presence of large, crushing icebergs but performs all the other phases during each profiling cycle. 14
The time in seconds between which the float momentarily awakens from the lowpower state to verify the piston position and check the pressure. If the pressure is more than MActivationPressure, the float goes into Mission mode. 3600
If set to 'on' the float will transition to the Emergency mode upon detection of an internal water leak. yes
The minimum pressure in decibars at which the float goes into Mission mode. It determines the float?s pressure activation depth. The float checks for this pressure periodically at the rate specified by IdleTimerInterval. 25
The minimum allowable buoyancy position in counts, overriding any other count setting. 147
The number of counts to change the piston position from its current position in the direction that will bring the float closer to the Park depth. 10
The maximum pressure difference in decibars between the actual pressure and ParkPressure. When exceeded, the piston position is adjusted by ParkBuoyancyNudge to move the float towards the Park depth. 25
The interval in seconds between float samples of the pressure to determine if the Park depth has been reached. The pressure is recorded to the science_log.bin file. 3600
The interval in seconds between float samples of the pressure to determine if the pressure is within the dead band specified by ParkDeadband. 5400
If set to 'on' the float will transit to the ParkDescphase at the end of the period determined by PreludeTime if the self tst passes. If the self tst fails, the float will go into Emergency mode. If set to 'off' the float will transit to the ParkDescphase yes
The press in decibars added to the most recently measured press at the surf, the sum of which is the press at which the conductivity, temperature and press sampling stops for a pumped type CTD. It is also the press at which the Surf phase begins. 4
