As Scripps Institution of Oceanography (SIO) celebrates 100 years, its oldest research unit, the Marine Physical Laboratory (MPL), turns 57, still carrying on the tradition of leading innovation in seagoing, experiment-oriented efforts to unravel the secrets of the ocean and the subsea environment. The emphasis at MPL in the early years was on ocean acoustics and geophysics/geology. Though its research base has expanded to include physical and biological oceanography and atmospheric and ocean optics research, acoustics and signal processing still play a central role as subjects of research and as methods of ocean exploration and imaging. Over more than a half century of existence, the emphasis at MPL is still on ocean observation and exploratory research with the parallel development.
