Investigations on the microbiology of marine air

All the viable microorganisms in the air have been transferred to the atmosphere either from the land or the sea. A comparison of the micro-flora of marine air with that of normal sea water and of land areas should indicate the major source of organisms in the atmosphere over the ocean

Bacteriological analysis of some long cores of marine sediments

Until recently only the uppermost layers of marine sediments have been generally available for scientific investigations since most coring instruments obtained samples less than a meter long. The early bacteriological investigations of Certes (1884), Russell (1892), Fischer (1894), Gazert (1912), and Drew (1912) were confined to surface samples obtained by dredging. Lloyd (1931) was the first to report quantitative data on the vertical distribution of bacteria in subsurface layers of marine sediments. Similar investigations were made by Reuszer (1933), and Waksman et al. (1933)

Sulfate-reducing bacteria in marine sediments

The occurrence of hydrogen sulfide in the waters of certain seas, fjords, and basins, as well as the presence of black or blue stinking sediments, can hardly escape the notice of any marine scientist. It is not surprising, therefore, that the eminent oceanographer Murray (Murray and Irvine, 1895) concerned himself with the nature of these materials and postulated their bacterial origin even before bacteriologists had described the specific organisms involved
