Ancient Greek Perception of the Ocean
To the ancient Greeks the ocean was an endless stream that flowed forever around the border of the world, ceaselessly turning upon itself like a wheel, the end of earth, the beginning of heaven. This ocean was boundless; it was infinite. If a person were to venture far out into it--were such a course thinkable--he…
Colors of Sea Life Match the Layer of Ocean in Which they Live, and the Light Spectrum that Reaches It
In a curious way, the colors of marine animals tend to be related to the zone in which they live. Fishes of the surface waters, like the mackerel and herring often are blue or green; so are the floats of the Portuguese men-of-war and the azure-tinted wings of teh swimming snales. Down below the diatom meadows and…
Does Oil Really Calm Waves?
The divers of ancient times who carried oil in their mouths to release beneath the surface when rough water made their work difficult were applying what every seaman today knows--that oil appears to have a calming effect on the free waves of the open ocean. Instructions for the use of oil in emergencies at sea are…
Schools of Croakers Sound Like Drill Machinery in the Chesapeake Bay
During the Second World War the hydrophone network set up by the United States Navy to protect the entrance to Chesapeake Bay was temporarily made useless when, in the spring of 1942, the speakers at the surface began to give forth, every evening, a sound described as being like 'a pneumatic drill tearing up…
Signs of Global Warming in 1950
...the evidence that the top of the world is growing warmer is to be found on every hand. The recession of the northern glaciers is going on at such a rate that many smaller ones have already disappeared. If the present rate of melting continues others will soon follow them. ...The glaciologist Hans Ahlmann reports…
The Continents Don't Move
...the outer portions of the basalt layer became solid and the wandering continents came to rest, frozen in place with the oceans between them. In spite of theories to the contrary, the weight of geologic evidence seems to be that the locations of the major ocean basins and the major continental land masses are today…
The First Charting of the Gulf Stream
The first chart of the Gulf Stream was prepared about 1769 under the direction of Benjamin Franklin while he was Deputy Postmaster General of the Colonies. The Board of Customs in Boston had complained that the mail packets coming from England took two weeks longer to make the westward crossing that did the Rhode…
The Many Waves and How They Interact in the Ocean
As long as there has been an earth, the moving masses of air that we call winds have swept back and forth across its surface. And as long as there has been an ocean, its waters have stirred to the passage of the winds. Most waves are the result of the action of wind on water. There are exceptions, such as the tidal…
The Ocean Regulates the Earth's Temperature
For the globe as a whole, the ocean is the great regulator, the great stabilizer of temperatures. It has been described as 'a savings bank for solar energy, receiving deposits in seasons of excessive insolation and paying them back in seasons of want.' Without the ocean, our world would be visited by unthinkably harsh…
The Perpetual Rain of Sediments to the Ocean Floor
For the sediments are the materials of the most stupendous 'snowfall' the earth has ever seen. It began when the first rains fell on the barren rocks and set in motion the forces of erosion. It was accelerated when living creatures developed in the suface waters and the discarded little shells of lime or silica that…
The Tides of Ancient Times Were Awesome Events
In the days when the earth was young, the coming in of the tide must have been a stupendous event. If the moon was, as we have supposed in an earlier chapter, formed in the tearing away of a part of the outer crust of the earth, it must have remained for a time very close to its parent. Its present position is the…
Tides Created the Moon
There were tides in the new earth, long before there was an ocean. In response to the pull of the sun the molten liquids of the earth's whole surface rose in tides that rolled unhindered around the globe and only gradually slackened and diminished as the earthly shell cooled, congealed and hardened. Those who believe…
