Over shallows even the water of the tropical oceans is always green.
Deidre awoke and looked at her then at her ankles. Katie was caught by the other woman's eyes. They were large and turquoise, like the shallows surrounding the Caribbean Sanctuary.
The chain of the Frisian Islands marks the outer fringe of the former continental coast-line, and is separated from the mainland by shallows, known as Wadden or Watten, answering to the maria vadosa of the Romans.
Similarly the obstructions offered to water communication by interruption through land or shallows are overcome by cutting canals or dredging out channels.
It is lowest in November, and rocks, shallows, and the remains of old dams then render it almost unnavigable.
South of this enclosed depression is another great hydrographic barrier which parts it from the low plains of the Amur, of China, Siam and India, bordered by the shallows of the Yellow Sea and the shoals which enclose the islands of Japan and Formosa, all of them once an integral part of the continent.
It is usually affirmed that the state of Venice owes its origin to the barbarian invasions of north Italy; that it was founded by refugees from the mainland cities who sought asylum from the Huns in the impregnable shallows and mud banks of the lagoons; and that the year 452, the year when Attila sacked Aquileia, may be taken as the birth-year of Venice.
The first accurate description of the plant is given by Theophrastus, from whom we learn that it grew in shallows of 2 cubits (about 3 ft.) or less, its main root being of the thickness of a man's wrist and 10 cubits in length.
That the plant was itself used also as the principal material in the construction of light skiffs suitable for the navigation of the pools and shallows of the Nile, and even of the river itself, is shown by sculptures of the fourth dynasty, in which men are represented building a boat with stems cut from a neighbouring plantation of papyrus (Lepsius, Denkm.
Small steamers ply on the Drina, Save and Una, but the Bosna, though broad from its very source, is, like the Vrbas, too full of shallows to be utilized; while the Narenta only begins to be navigable when it enters Dalmatia.
Nor are there any long rivers, and all are so broken by shallows and rapids that navigation is generally impossible except by means of flat-bottomed boats drawing only a few inches.
Harbours and shallows covered with Zostera are likewise favourite haunts of this species, although the water may be brackish.
The Baltic Sea exceeds 50 fathoms in few places except the broad central portion, though small caldron-like depressions here and there may sink below zoo fathoms. The Red Sea on the other hand, though shut off from the Indian Ocean by shallows of the Strait of Bab-elMandeb with little more than ioo fathoms, sinks to a very considerable depth in its central trough, which reaches 1209 fathoms in 20° N.
In the dry season, however, it is obstructed by reefs, sandbanks, shallows, snags, trees and floating timber from the "Apostadero" up, so that even canoes find its ascent difficult, while savage hordes along its banks add to the dangers to be encountered.
The principal sea-inlets in the north are the Texel Gat or Marsdiep and the Vlie, which lead past the chain of the Frisian Islands into the large inland sea or gulf called the Zuider Zee, and the Wadden or " shallows," which extend along the shores of Friesland and Groningen as far as the Dollart and the mouth of the Ems. The inland sea-board thus formed consists of low coasts of sea-clay protected by dikes, and of some high diluvial strata which rise far enough above the level of the sea to make dikes unnecessary, as in the case of the Gooi hills between Naarden and the Eem, the Veluwe hills between Nykerk and Elburg, and the steep cliffs of the Gaasterland between Oude Mirdum and Stavoren.
The total length of navigable channels is about 1150 m., but sand banks and shallows not infrequently impede the shipping traffic at low water during the summer.
The South Beveland (1862-1866) canal connects the East and West Scheldt; similarly in South Holland the Voorne canal unites the Haringvliet with the New Maas, which does not allow the passage of large vessels above Brielle; whilst owing to the banks and shallows in front of Hellevoetsluis the New Waterway was cut to Rotterdam.
In the monsoon the Cochin backwaters are broad navigable channels and lakes; in the hot weather they contract into shallows in many places not 2 ft.
Yahweh then causes a strong east wind to blow all that night, which drives back the waters from the shallows, and so renders it possible for the host of Israel to cross over.
They occur also abundantly in the shallows of rivers and fresh-water lakes, and in less number in salt lakes and in the sea; such aquatic Angiosperms are not, however, primitive forms, but are derived from immediate land-ancestors.
Long and navigable by rafts and light boats for 50 m., flows north and north-east with numerous rapids and shallows, and enters the Sea of Okhotsk.
As a rule they have been constructed on islets or shallows in the lochs, which have been adapted for occupation, and fortified by single or double lines of stockaded defences drawn round the margin.
Birch trees are thrown into the water near a natural bed of oysters, and the trunks and twigs become covered with spat; the trees are then dragged out upon the shore by oxen, and the young fry are broken off and laid down in the shallows to increase in size.
The western and northern coasts are regular in outline with long straight beaches; and shallows are common in the seas that wash them.
Owing to the prevalence of shallows and sandbanks, navigation is difficult.
In the dry season it has shallows, and is obstructed by sandbanks, a few rapids and granite rocks.
There were no cities or large towns before the arrival of the Norsemen; no stone bridges spanned the rivers; stepping stones or hurdle bridges at the fords or shallows offered the only mode of crossing the broadest streams, and connecting the unpaved roads or bridle paths which crossed the country over hill and dale from the principal dials.
I&op, water, and 'pu u', to write), the science dealing with all the waters of the earth's surface, including the description of their physical features and conditions; the preparation of charts and maps showing the position of lakes, rivers, seas and oceans, the contour of the sea-bottom, the position of shallows, deeps, reefs and the direction and volume of currents; a scientific description of the position, volume, configuration, motion and condition of all the waters of the earth.
Notwithstanding serious obstacles offered by shallows, corn, fish, salt and timber are largely shipped to and from Archangel.
