  Submersible Buoy (SB) is an important apparatus capable of long-term,
fixed-point, continuous and multi-directional measurement of acoustic signals
and hydrological environment monitoring in the harsh marine environment,
providing important information for hydrological environment research, marine
organism research and protection. We will describe a real-time data acquisition
(DAQ) system with multiple designs to meet low-power consumption and high-speed
data transmission.
