“Dissolved” organic matter (DOM) in seawater was fractionated by filtration with filters of different pore size. Samples below 600 m in one station of the East China Sea contained 0.1–0.5‐ µ DOM. In a sample from 1,573 m, DOM between 0.1 and 0.5 µ amounted to 24% of the total. In other stations, a large part of the DOM was composed of fractions smaller than 0.1 µ. The nature of 0.1–0.5‐ µ DOM is discussed.
