China's homegrown core equipment for deep-sea oil and gas exploration was officially put into use in the Bohai Sea on Thursday, marking a milestone achievement in the country's sci-tech empowerment in this regard. Node-mode offshore seismic data exploration and acquisition equipment nicknamed "sea pulse"s uses several leading-edge technologies including an ultra-low noise acquisition circuit, and a greatly improved signal detector. 

Thousands of "sea pulses" are placed at designated positions on the seabed to receive and record seismic wave signals. After the operation is completed, they will be retrieved, and the data will be analyzed by experts who will "take the pulse" of the seabed.
