By the time the actual southern voyage commenced, each individual had his own particular line of work which he was prepared to follow out. The biologist at first confined himself to collecting the plankton, and a start was made in securing water samples for temperature and salinity.
The vats of plankton and algae concentrates were not so important as to orientation, but should be fed into their rim-river homes as soon as possible, although this could not be done until the rim spin was well under control.
When the proper balance of plankton and algae was achieved, the air jets that gave the ship its spin would also purify the ship's air, giving it back in a natural manner the oxygen it was now fed from tanks.
While Amundsen and his companions were passing the winter in the South, Captain Nilsen, in the Fram, investigated the ocean between South America and Africa. At no fewer than sixty stations they took a number of temperatures, samples of water, and specimens of the plankton in this little-known region, to a depth of 2,000 fathoms and more.
From this to the chemical composition of sea water, the total salt about 3.5 per cent, but variable: the proportions of the various salts do not appear to differ, thus the chlorine test detects the salinity quantitatively. Physically plankton life must depend on this salinity and also on temperature, pressure, light, and movement. Why should biologists strive for deeper layers?
She glanced at her watch, walked around a scale model of Harvest Moon, the O.G. station, which occupied the center of the Hall, and went on among the exhibits. There were views taken on Manon Planet in one alcove, mainly of Manon's aerial plankton belt and of the giant plasmoids called Harvesters which had moved about the belt, methodically engulfing its clouds of living matter.
On December 10 we stopped the ship and secured her to a heavy floe from which we took in sufficient ice to make eight tons of fresh water, and whilst doing this Rennick sounded and obtained bottom in 1964 fathoms, fora-minifera and decomposed skeleton unicellular organs, also two pieces of black basic lava. Lillie and Nelson took plankton and water bottle samples to about 280 fathoms.
Each phylum may include several classes. PICKELHAUBE. The spiked helmet of the German army. PLANKTON. Sea animals and plants collectively; distinguished from coast or bottom forms and floating in a great mass. Pertaining to the habit of having more than one mate of the opposite sex. POLYPHRASTIC. Having many phrases; pertaining to rambling, incoherent speech.
While a few of the rivers were in a nearly chemically pure state, most of them were already filling with the plankton and algae that would form the base of the major ecological experiments, some with fresh water as their medium, others using sea water, complete with its normal micro-organisms supplemented from the tanks of concentrate that Dr. Millie Williams had brought aboard.
They grow up street arabs, slum waifs, the driftwood of society, its flotsam and jetsam, or plankton, fighting for a warn corner in their resorts or living in crowded tenement-houses that rent for more than a house on Fifth Avenue. Arrant cowards singly, they dare and do anything together.
