The total array consists of three MTA's; a 32 element, 5 MHz, MTA and 2 - 2 MHz, 16 element, MTA's.  Transducer spacing is 1.5 and 6 cm for the 5 MHz and 2 MHz arrays respectively.
Each MTA is a stand-alone system. Each has a data-logger and all required electronics in its own pressure housing. The MTA's are capable of recording two entire seabed  profiles a second. The data-loggers can either run independently or communicate with an outside processor and offload the data whenever prompted. 
The instrument has proven capable of measuring both small and large scale bedforms in the near-shore ocean environment.
