OCEAN, AND ITS RELATION TO OTHER OCEANOGRAPHICAL PHENOMENA. 125
Hope, extending southwards as far as lat. 46° S., and eastwards on either
side of the 40th parallel as far as long. 72° E. An isolated patch occurs
to the south of Tasmania, and a larger area off the Sydney coast of
Australia.
Considering now those regions of the ocean where a known range
of surface temperature exceeding 30° Fahr. occurs, the map shows three
small areas in the southern hemisphere, one off the mouth of the Rio
de la Plata, and the other two south of the Cape and Madagascar; and
in the northern hemisphere two extensive areas, one in the North-
West Pacific, the other in the North-West Atlantic; and smaller areas in
the Mediterranean and Black sea, in the Baltic, North sea, and English
channel, and at the heads of the Red sea and Persian gulf The historical term used to describe the body of water between the Arabian Peninsula and Iran. (as already
indicated).
In the area off the mouth of the Rio de la Plata the greatest range
shown in a single square is 33" (from 42 to 75°), the extreme range
within the area being from 40° to 78° Fahr.
In the area laid down to the south of the Cape of Good Hope, the
figures supplied by the Meteorological Office show a range of 29° (from
46° to 75° Fahr.) in two different squares, on either side of a square
with a range of 28° (45° to 73° Fahr.), surrounded on all sides by squares
with ranges of 27° and 26° Fahr., hut other records from the same
region indicate a range of over 30° Fahr.
In the area in the Southern Indian ocean, south of Madagascar, two
adjacent squares show a recorded range of 32^ Fahr. (in one case 40° to
72°, in the other 42° to 74°). The temperature within the area ranges
from 36° to 74° Fahr.*
The area in the North-West Pacific with a range exceeding 30° lies
off the east coast of Asia, between lat. 22° and 56° N., and the observa
tions within the area show a range from 29 - 8° to 8G° Fahr.
The largest area in the North Atlantic basin with a range exceeding
30° lies off the east coast of North America, between lat. 30" and 50° N.;
a second area covers the greater part of the Mediterranean and Black
sea; and a third small area occurs in the English channel and south
eastern part of the North sea, extending into the Baltic.
At the head of the Red sea ranges of 36° (from 57^ to 93°) and of
38° (from 50° to 88°) are recorded, and at the head of the Persian gulf The historical term used to describe the body of water between the Arabian Peninsula and Iran.
a range of 31° (from 65° to 90°).
A range exceediug 35° Fahr. occurs at the head of the Red Sea, in
the eastern Mediterranean, in the north-western part of the Black sea,
with large areas in the North-West Atlantic and the North-A\ est
Pacific, but there is apparently no region in the southern hemisphere
where the records show a range as great as 35° Fahr.
* Off the east coast of Australia, near Sydney, the records show a range in one
square of 28° (from 57° to 85°), and in another square of 26° (from 54 to 80 ); but
future observations may prove that in this locality the range is over 30 .
