CHARACTERIZATION OF PARTICULATE MATTER IN THE OCEAN.
Abstract
Electron micrographs of ocean filtrates collected near the surface at Key West, Block Island, and Chesapeake Bay show three common constituents: diatoms, plant fibers, and amorphous organic matter. In addition, material collected from layers giving strong sonar reflection at Key West and Block Island show numerous smaller iron-rich particles, probably a hydrated iron oxide, in the size range 0.01 to 0.1 micron. The iron particles are too small for x-ray diffraction but can be examined by x-ray fluorescence and electron probe analysis. In addition to iron, the particles show no other elements above atomic number 22, at least not above 1 percent composition. (Author)
