Martin Wiggo Johnson (September 30, 1893 – November 28, 1984), was an American oceanographer at Scripps Institution of Oceanography. He is known as an author of the landmark reference work ''The Oceans: Their Physics, Chemistry and General Biology'' (1942, 1970); for explaining the deep scattering layer (DSL) as a result of what is now called the diel vertical migration; and for studies of zooplankton that revealed that the physics of water movement was an important influence on population biology and community diversity.
