No, a different world completely, but similar in that it has a sun, moon, oceans, grass, and stuff.
Above sea-level, and the mean depth of the oceans as 2080 fathoms or 12,480 ft.
Wagner, and subsequently by Penck and Heiderich, and for the oceans by Karstens.
Thus the connecting belt of water is narrow as compared with the extent of the oceans from north to south - Drake Strait south of South America is barely 400 m.
In 1777, while on his way to search for a north-east passage between the Atlantic and Pacific oceans, Cook again touched at the coast of Tasmania and New Zealand.
Although not the most extensive of the great oceans, the Atlantic has by far the largest drainage area.
Most geologists include the Atlantic with the other oceans in the view they adopt as to its age; but E.
THE TROPIcAL REGI0N.The permanence of continents and great oceans was first insisted upon by J.
The area of the dry land was taken as 28.3% of the surface of the globe, and that of the oceans as 71.7%.
The whole of the available data were utilized by the prince of Monaco in 1905 in the preparation of a complete bathymetrical map of the oceans on a uniform scale, which must long remain the standard work for reference on ocean depths.
The percentages of the land surface draining to the different oceans are approximately - Atlantic, 34'3%; Arctic sea, 26.5%; Pacific, 14.4%; Indian Ocean, 12.8%.'
In the first, the Periplus of the Outer Sea, in two books, in which he proposed to give a complete description of the coasts of the eastern and western oceans, his chief authority is Ptolemy; the distances from one point to another are given in stades, with the object of rendering the work easier for the ordinary student.
The Heteropoda belong to the " pelagic fauna " occurring near the surface in the Mediterranean and great oceans in company with the Pteropoda, the Siphonophorous Hydrozoa, Salpae, Leptocephali, and other specially-modified transparent swimming representatives of various groups of the animal kingdom.
- Oncidium tonganum, a littoral Pulmonate, found on the shores of the Indian and Pacific Oceans (Mauritius, Japan).
Although the species are fewer in number than in most other families of fishes, they are widely spread and extremely abundant, peopling by countless schools the oceans of the tropical and temperate zones, and approaching the coasts only accidentally, occasionally, or periodically.
This deviation is the adoption of an aquatic mode of life by the European fresh-water spider (Argyroneta) and by the marine spider Desis, which is found on the shores of the Indian and Pacific Oceans from Cape Colony to eastern Australia.
Penck proposed to prepare a map of the world, including the oceans, on a scale of 1: 1,000,000, and his scheme was promised the support of a committee which met in London in 1909, and upon which were represented the leading powers of the world.
A bathymetrical chart of the oceans, by Professor J.
The relative abundance of nitrates and nitrites at the bottom of deep oceans as compared with the surface can be explained in the same way, for at the bottom the temperature is about zero Centigrade and the activities of the denitrifying bacteria are practically suspended.
And Geographically, Siberia is now limited by the Ural Mountains on the W., by the Arctic and North Pacific Oceans on the N.
Thus Spain laid claim to exclusive dominion over whole oceans, Great Britain to all her environing narrow seas and so on.
The pest even crossed the oceans, and appeared in Australia, at Geelong, about 1880; it has since twice broken out in Victoria, and has ravaged the vineyards of South Australia and New South Wales.
A simple, practical boundary between the three oceans can be obtained by prolonging the meridian of the southern extremity of each of the three southern continents to the Antarctic circle.
A committee of the Royal Geographical Society - the deliberations of which were interrupted by the departure on his last voyage of Sir John Franklin, one of the members - suggested these meridians as boundaries; the north and south boundaries of the Atlantic and Pacific Oceans being the polar circles, leaving an Arctic and an Antarctic Ocean to complete the hydrosphere.
Some authors include the Arctic Sea in the Atlantic Ocean, and some prefer to consider the southern part of the Atlantic, Indian and Pacific Oceans as a Great Southern Ocean.
As limits; but in none of these schemes has the coast of Antarctica been adequately considered, and they have all been too much influenced by the Mercator map. Each of the three oceans, Atlantic, Indian and Pacific, possesses an Antarctic facies in the southern part and a tropical facies between the tropics, and the Atlantic and Pacific an Arctic facies in their northern parts.
In these respects they contrast with the great oceans which owe their origin to the most extensive and the profoundest depressions of the crust, date back at least to Mesozoic times, and have perhaps remained permanently in their present position from still remoter ages.
The fringing or partially enclosed seas adjoin the great land masses and are only separated from the oceans by islands or peninsulas.
Hecker took the opportunity of a voyage from Hamburg to La Plata, and in 1904 and 1905 of voyages in the Indian and Pacific Oceans to determine the local attraction over the ocean by comparing the atmospheric pressure measured by means of a mercurial barometer and a boiling-point thermometer, and obtained results similar to Scott Hansen's.
A line detached a float on striking the bottom, and it was proposed " Gazelle " conducted observations in the South Atlantic, Indian to calculate the depth by the time required for the float to reand South Pacific Oceans; and the U.S.S.
Since that the moment of the lead touching the bottom by the sudden time the British cable-ships have been busy in all the oceans slackening in the rate at which the line ran out.
The north of the chain, from the Kuriles to Formosa, belongs to the empire of Japan; southward it is continued by the Philippines (belonging to the United States of America) which link it with the vast archipelago between the Pacific and Indian oceans, to which the name Malay Archipelago is commonly applied.
In1522-1524various voyages of discovery were made on the west coast of America, partly in the hope of finding a strait connecting the two oceans to the region of the central isthmus.
In the oceans alone there are estimated to be 1141 X 10 12 tons of sulphate, K 2 SO 4, but this inexhaustible store is not much drawn upon; and the "salt gardens" on the coast of France lost their industrial importance as potash-producers since the deposits at Stassfurt in Germany have come to be worked.
America, broadening in the north as if to span the oceans by reaching to its neighbours on the east and west, tapering between vast oceans far to the south where the nearest land is in the little-known Antarctic regions, roughly presents the triangular outline that is to be expected from tetrahedral warping; and although greatly broken in the middle, and standing with the northern and southern parts out of a meridian line, America is nevertheless the best witness among the continents of to-day to the tetrahedral theory.
The relation of the Americas to each other and to the rest of the world, as the home of plants and animals, is greatly affected by the breadth of the adjacent oceans, and also by the geologically recent changes of altitude whereby the breadth of the narrower parts of the lands and the oceans has been significantly altered.
The currents produce a considerable rearrangement of this simple order, the belts of warm water being wider on the western sides of the oceans and narrower on the eastern.
The surface temperature of the Atlantic is relatively lower than that of the other oceans when the whole area is considered.
The general lines of the currents of the oceans are fairly well understood, and along the most frequented ocean routes the larger seasonal variations have also been ascertained.
The existence of a layer of water of low salinity at a depth of 500 fathoms in the tropical oceans of the southern hemisphere is to be referred to this action of the melting ice of the Antarctic regions.
Pettersson's view that ice-melting dominates the 'whole circulation of the oceans and regulates in particular the currents of the seas round northern Europe must, however, be looked on as carrying the explanation too far.
The four great continental masses therefore give the ocean a distinctly tripartite form, the three great divisions being known as the Atlantic, the Indian and the Pacific Oceans, all three running together into one around Antarctica.
