Reading the Change of Seawater Color
Reading the Change of Seawater Color
Light reflection, depth, quality and
composition of seabed, and blockage of light by clouds affect the change of
seawater color. The darkest blue to black indicates deep water; the more it is
lighter and purer, the less the depth is. Light green is less deep with a brown
seabed. Brown indicates shallow and muddy water full of marine grass. Black
indicates very less deep water with rocky dangerous ground, and it is
classified as bare.
Pieces and small rocks in the Red Sea
Pieces and small rocks in the Red Sea
They are tops just like islands. However, they
do not rise above sea level, i.e. they are submerged in different heights. They
are dangerous because heights are variable; some of them can be passed through
if they are 2 – 4 meters high. The more we approach the tops, the lesser and
more dangerous the height will be during sailing. Sometimes, they are uncovered
when the sea recedes. In less-high places, we see water shatters. Some of their
compositions are sandy, rocky, and smooth; others are sharp and dangerous and
can be detected when water color changes. Light green means that they are of
sandy seabed, black means they are rocky, and some range between green and
black because rocks are distributed over them. Therefore, it is necessary to
turn around them from an adequate distance. However,those, which are close to
sea surface as a flat top, will be detected by wave hitting if you see them in
front of you. So, change the course and go through deeper water which tends to
be dark blue.

They are land areas consisting of sand tops
mounted on rocky compositions arising from seabed. Areas differ according to
their configuration. They may be the surface of a mountainous chain or a single
top; these are usually of a lesser area.As well, their prominence and height
from sea level differ. They have many bushes.Many organisms live there because
they consider it a suitable environment to reproduce in such as turtles and
immigrant birds. It is surrounded by a sand coast extending downward to the
sea; it may be rocky and deep at the end where waves strike heavily to surround
depths around it. It is difficult for boats to approach it due to strong pushing and reversing currents.

Nature of Coasts in the red sea
Nature of Coasts
The Red Sea coasts are characterized by their
long extension of coral reefs consisting of coral rocks. There are also some
bays that constitute internal water areas which are both wide and narrow
linearly. There are some islands of different areas; therefore, we find depths
in this distribution varying between less, moderate, and very deep. The danger
of entering and exiting is due to these terrains of the Red Sea either on
coasts or when leaving them. This is dangerous when sailing to fish.
Wind Movement in the red sea
Wind Movement in the red sea
The Red Sea is affected by normal and reverse
seasonal winds except the northern part of the Red Sea which is dominated by
continuous northwest winds with 7km/hour and 12km/hour velocity. The movement
of seasonal and regional winds is characterized by changes in velocity and
direction with a general increase of average velocity northward.
Risk of coral reefs
Risk of coral reefs
I dedicate this topic for our dearest
beginners who have boats but lack navigational experience sice they are not
aware of sea terrains and variables when entering to fish. This is according to
my modest expertise.The topic is also open for experts to correct or add in
case there is deficiency in order to make it a good reference that benefits
beginners and avoids them many risks God willing.
Since
I know the Western Province, I will talk about the Red Sea which is moderate in
terms of area and configuration.It is also one of the most dangerous seas for
ships and fishing boats due its terrain variables represented in many coral
reefs that threaten marine media because they are close to the surface.Conflicts in the Red Sea
Conflicts in the Red Sea
The Red Sea is important not in itself, but
because of its position and the its resources of countries at its shores from
Egypt to Saudi Arabia, Yemen, and Sudan. These countries have great volumes of
oil and gas. On their coasts, pipelines, terminals, and ports, these essential
materials are exported to all parts of the world from Japan and China to Europe
and the Americas. Thus, these countries consider that the energy resources,
existing in this part of the world (about 60% of world reserve) and necessary
for their advancement, industries, people’s welfare, and national security,
cannot be left for coincidence, liable to national or international risks that
prevent them from obtaining these resources in the fastest and cheapest ways. In
the place where these resources are, these countries have started to interfere
indirectly then directly in order to extract resources and ensure their
transport lines via seas to these countries. These countries established points
in seas and straits from the Suez Canal to the Strait of Mandeb and Strait of
Hormuz on the Persian Gulf, and Indonesian Strait of Malacca across the Indian
Ocean, Mediterranean Sea, Gibraltar, and Atlantic Ocean.
Nowadays, this importance increases due to
tension in Gulf region. This is either due to the conflicts among its
countries, between the United States of America and European countries and Iran
because of the Iranian nuclear issue, and American-Israeli threats to strike
Iran which may result in spillovers and consequences that may lead to close the
Strait of Hormuz and stop transporting energy to various countries worldwide.
Suez Canal
Suez Canal
The Suez Canal is an artificial sea-level
waterway which is 193km long between Port Said on the Mediterranean Sea and
Suez on the Red Sea.. It is divided into two parts in the north and south of
Bitter Lakes. The Canal allows the crossing of ships coming from Mediterranean
countries, Europe, and America to access Asia without taking the long road -
the Cape of Good Hope. It took 10
years to build the Suez Canal (1859-1869(. In 2010, the revenues of the Suez Canal reached
about 4.8 billion US dollars. The largest fees paid to ship for passing
through the Suez Canal were 2.000.028 dollars. An Italian cargo ship of 59
thousand tons capacity paid these fees. The ship passed through the Suez Canal
on September 7, 2011. The Suez Canal is the most important navigational course
in the world.It controls 40% of the movement of ships and containers in the
world. It also connects the countries of Southeast Asia, Europe, and the
Americas.
The Strait of Mandeb
The Strait of Mandeb
The Strait of Mandeb (25-29km wide) can be
considered one of the most important sea-level waterways necessary for trade
traffic and energy transport in the world. Through it, 15% of international
shipsmove roundtrip. The Strait is located between Yemen
coasts from the east and Djibouti from the west. In the Strait, there is Yemeni
Perim Island which splits it into to crossings (an eastern crossing which is
3km wide and 30m deep, and s western crossing which is 30km wide and 300m
deep). Ship traffic depends mostly on this Strait.Strategically, this Strait
cannot be separated from Gulf of Eden, Yemen, Arabian Sea, and Somalia from the
south and east as well as Ethiopia and Eritrea from the north and west.
Islands in the Red Sea
Islands in the Red Sea
This sea contains a big number of strategic islands the most important of which are: Perim Island - located in the Strait of Mandeb -, SaudiFarasan Islands, Eritrean Dahlak Archipelago, and Yemeni Hanish Islands, after a Yemeni-Eritrean conflict to claim their ownership.
Kingdom of Saudi Arabia has the longest coast on this Seafollowed by Egypt, Eritrea, Sudan, Yemen, and Djibouti. Whereas,in the north, the costs of Palestine and Jordan are relatively short.Yet, they have a strategic position, especially Port of Eilat, Aqaba, and Taba. In the south, Eritrea, Djibouti, and Yemen have a strategic position on the Strait which controls the entry to this Sea northward, the Suez Canal, and then to the Mediterranean.
Sharks in the Red Sea
Sharks in the Red Sea
In 2010, the Egyptian government closed the touristic hotspot Sharm el-Sheikh and banned swimming at that place as a result of some dangerous shark attacks; one of these attacks was fatal. Since December in 2010, scientists have been investigating these attacks. They managed to identify some potential reasons,but could not recognize their validity, like excess fishing which pushes large sharks to approach the coast to hunt, touristic boats’ operators who drop baits in order to photo sharks, and some reports involve throwing animal corpses from some passing-by ships.Furthermore, the geography of some parts of the Red Sea enables large sharks to wander by the coast sometimes. This is due to the Sea narrowness, deep water, and sharp slope. These three factors altogether constitute a suitable place for large sharks to wander in hundred meters of deep water and reach some hundred meters of swimming zones .

What I personality believe about the Red Sea is
The weather in the summer is very humid. Also, because of the width of the Red Sea, raining is little in the Arabian.
However, do you believe if the width of the Red Sea is big, the raining will be so strong in the west?
Please check the map that I design about it.
How the Red Sea Got its Name?
How the Red Sea Got its Name?
How the Red Sea Got its Name?
The reason to got this name is because of the red Coral but I think this naming is wrong.
Different seas in the world have different color some of them is red, green and black.
However, What I believe the reason to got this name because the Egypt Mountains is red and The glow of the sky reflected in its waters
A lot of authors wrote about it. What we are going to talk about it.

The Red Sea is an extension (or inlet) of the Indian Ocean, located between Africa and Asia.
Entrance to the sea in the south is through the Gulf of Aden and the somewhat narrow Bab el Mandeb (strait).
In the north the sea is accessed from Middle Eastern countries via the Gulf of Aqaba (or Gulf of Eilat.) The Mediterranean Sea provides a conduit south through the Suez Canal and Gulf of Suez.
This salty sea is just over 190 miles (300 km) across at its widest point, and about 1,200 miles (1,900 km) in length.
There's a measured maximum depth of 8,200 feet (2,500 m), and an estimated average depth of 1,640 feet (500 m). Much of the immediate shoreline is quite shallow.
With hot sunny days, and the lack of any significant rainfall, desert dust storms are known to sweep across the sea. High heat combined with the lack of precipitation facilitates high levels of evaporation - thus the sea's high salinity.
Regardless, the consistent sunshine, as well as white sand beaches, pristine coral reefs and a scattering of shipwrecks are major attractions for scuba divers and sun worshipers. Resorts like Sharm al-Sheikh and others in Egypt's "Red Sea Riviera" along the Gulf of Aqaba and Gulf of Suez are fast becoming major tourist destinations.
