A TYPICAL PROFILE CYCLE DONE BY THE AMP PROFILER. THE PROFILER SPENDS MOST OF ITS TIME AT A SPECIFIED PARK DEPTH (50-60 M), WHICH KEEPS IT AWAY FROM SURFACE TRAFFIC AND WAVES AND MINIMIZES BIOFOULING. AT SPECIFIED INTERVALS (USUALLY DAILY), THE PROFILER CONTROLLER WAKES FROM ITS LOW POWER SLEEP STATE, POWERS UP THE INSTRUMENTS, AND ASCENDS TO THE SURFACE AT 25-30 CM PER SECOND. AT THE SURFACE, THE CONTROLLER CONNECTS INTO A SERVER VIA A CELLULAR MODEM TO SEND OUT DECIMATED DATA AND RECEIVE NEW PROFILING INSTRUCTIONS. AFTER A SHORT TIME AT THE SURFACE, THE PROFILER WINCHES ITSELF BACK TO THE PARK DEPTH.
