Simpli? ed ? owchart of the ? rmware for integrated operation of the lander. During the moored mode, the DAC increases the sampling period of the oceanographic instruments to 10 min. During this period, the system remains in sleep mode, only waking up every 1 min to measure the depth, without turning on the CTD pump. “C_min” is a threshold conductivity to start the downcast, “Th” is a bottom detection algorithm, “P_N” is Pmax +Pnoise control parameter, “P_Sh” is depth to ? nish upcast.
