THE POSSIBLE OCCURRENCE OF PHOTOSYNTHETIC MICROORGANISMS IN DEEP‐SEA SEDIMENTS OF THE NORTH ATLANTIC1,2,3

摘要: SUMMARY An assemblage of 12 diatom species and other photosynthetic microorganisms associated with red clay sediments collected from a depth 6150 m in the North Atlantic was observed to bloom Antarctic bottom water when exposed sunlight at sea surface temperature. Although no growth could be detected over first 3 days experiment, nitrate nearly completely stripped water. The maximum rate 4.7 doubling/day reached between 4 5. Most have been described as littoral or coastal forms, it is suggested that these organisms are transported by fecal material, turbidity currents, combination two.
