Observations have been made on two cruises in the North Atlantic in which large numbers of microscopic, unicellular flagellates have been found throughout the aphotic zone below 1000 meters. Preliminary measurements also indicate the uptake of dissolved organic substances, suggestive of an apparently viable, actively metabolizing community at these depths.
