I. Introduction

Definition and location of the Red Sea

The Red Sea is an arm of the Indian Ocean located between Asia and Africa. It stretches from Suez in Egypt, initially as the Gulf of Suez, down about 1930 kilometers to the Strait of Mandeb, which connects with the Gulf of Aden and Arabian Sea. The coasts of Egypt, Sudan, and Eritrea are on one side of the sea, while Saudi Arabia and Yemen border the other side. The Gulf of Aqaba, which extends to southern Israel and southwestern Jordan, is a northeastern extension of the sea. The Red Sea has warm and salty water, making it a unique and popular destination for tourists, divers, and underwater photographers who come to explore its coral reefs. The name "Red Sea" is derived from the color changes observed in its waters, which often appear reddish-brown due to the presence of algae. The sea played an important role in the history of ancient civilizations, including the Egyptians, Greeks, and Romans. Its strategic location made it an important commercial route for centuries, and it continues to be one of the most heavily traveled waterways in the world today, carrying traffic between Europe and Asia via the Suez Canal.

II. Physical Characteristics

Surface area, length, and width of Red Sea

The Red Sea is a fascinating body of water renowned for its unique location and features. Covering a surface area of roughly 438,000 square kilometers, it is approximately 2,250 kilometers long and 355 kilometers wide at its widest point. The sea has an average depth of 490 meters, while in the central region, it reaches its maximum depth of 3,040 meters. Interestingly, only about 40% of the Red Sea is quite shallow, and about 25% is less than 50 meters deep. This fascinating geographical feature of the Red Sea has enabled it to support a diverse range of marine life, with over 1,000 species of fish and 200 types of soft and hard corals having been identified. The shallow shelves that characterize the sea have an even richer marine life, making it an excellent diving and snorkeling spot, and are noted for their underwater beauty. The Red Sea’s unique location has made it an essential navigational passageway since ancient times, with various commercial routes crisscrossing its waters for centuries. Its strategic location has also had an impact on its history, as the sea has been associated with the Biblical account of Israelites fleeing slavery in Egypt. 

Average and maximum depth of Red Sea

The Red Sea is one of the most unique marine ecosystems in the world, thanks in part to its average and maximum depth. The average depth of the Red Sea is 490 meters, while the maximum depth reaches 3040 meters in the central part of the sea. This makes the Red Sea one of the deepest bodies of water in the world. What's remarkable about the Red Sea is that approximately 40% of it is quite shallow, less than 100 meters deep, while around 25% is less than 50 meters deep. These shallow shelves are known for their diverse marine life, and more than 1,000 species and 200 types of soft and hard corals call the Red Sea home. The Red Sea's seabed is characterized by trenches, valleys, and numerous underwater canyons. The trough in the central part of the Red Sea is the deepest point, and the steep walls of the narrow coastal channels create a unique underwater landscape. Additionally, because the Red Sea is landlocked and has no direct connection to other oceans, it has a high salinity level and a unique ecosystem that is well adapted to the hot and arid environment. With its shallow shelves, diverse marine life, and unique underwater features, the Red Sea is truly an aquatic wonderland. 

Shallow shelves and marine life of Red Sea

The Red Sea is known for its extensive shallow shelves, which make up important habitats for the diverse marine life found in the region. The fringing reef systems that dominate the Red Sea's coastline have been growing for over 5000 years, offering shelter and support for a wide range of species. Interestingly, the Red Sea's extreme conditions - high salinity, high temperature, and occasional turbidity - have led to a unique adaptation in the region's corals, which have developed an unusually high tolerance to these conditions. This has allowed for the growth of a diverse range of coral species, and in turn, a diverse range of marine life.

The Red Sea's unique geological history and location also contribute to the high level of endemism found in the region's marine life. Of the over 1200 species recorded, about 10% are found exclusively in the Red Sea. This incredible biodiversity includes hundreds of species of hard corals, as well as a vibrant array of fish, invertebrates, and other marine species. 

While the Red Sea is a haven for marine life, it is important to note that there are still factors threatening the health and survival of these fragile ecosystems. Poorly planned coastal development and unregulated dive tourism have led to damages in some areas, and climate change continues to threaten reefs across the globe. However, with active conservation efforts led by several countries within the region, there is hope for the continued protection and preservation of the Red Sea's shallow shelves and the rich marine life they support. 

III. Geographical Names

Historical and modern names of the Red Sea

The Sea has been known by various names throughout history, some of which are still used today. Its modern name, the Red Sea, is said to be derived from the seasonal blooms of red-colored algae near the water's surface. However, there are other theories behind the name's origin. For instance, some scholars think that the name refers to the direction south, the same way the Black Sea's name may refer to the north. Another theory is that the name stems from the Himyarite people, a local group whose name means "red," who inhabited the area in ancient times.

The association of the Red Sea with the Israelites' escape from slavery in Egypt, in particular, the account of the miraculous crossing of a body of water known as the "Reed Sea," goes back to the translation of the book of Exodus from Hebrew into Koine, in which Hebrew "Yam Suph" meaning Reed Sea is translated as the Red Sea. It is also the name for the Red Sea in modern Hebrew. 

The Red Sea has a long and storied history, and this is reflected in its multitude of historical and modern names. Whether you call it the Red Sea, the Sea of Edom, or the Sea of Reeds, its importance in global history cannot be denied. Even today, the Red Sea remains a vital hub of trade and commerce, connecting Asia and Africa.

Theories behind the name Red Sea

Theories behind the name Red Sea have been debated for centuries, but one thing is for sure, it is a captivating and diverse body of water. Some believe that the name originates from the red-hued sea sawdust, a type of bacteria that grows near the water's surface. Others believe that the red in the Red Sea is actually a designator of the sea's location relative to the ancient Mediterranean world - to the South. In ancient languages, the colors black, red, green, and white referred to North, South, East, and West, respectively. A popular theory among modern scholars is that the name is referring to the direction South, just as the name "Black Sea" refers to the North. Along with the name's origins, the Red Sea has historical and modern ties to the Israelites, who crossed its waters in the biblical account of Exodus. In terms of tourism, the Red Sea is a top destination for snorkeling enthusiasts, showcasing over 1200 species of fish in a vibrant coral reef ecosystem. With its diverse marine life, the Red Sea is designated a Marine Protected Area. Despite its name's unknown origins, the Red Sea continues to fascinate scientists, historians, and tourists alike.

IV. Biblical and Historical Significance

Association with Israelites

The Red Sea has a strong association with the Israelites, thanks to the biblical narrative of their escape from the pursuing Egyptian army. According to the story, Moses held out his staff and God parted the waters of the sea, allowing the Israelites to cross on dry ground. Once they had safely crossed, Moses dropped his staff and the sea closed, drowning the pursuing Egyptians. This event is commemorated in the Song of the Sea, in which the Israelites sang in praise of the Lord for their deliverance. The term "Red Sea" is a mistranslation, as the Hebrew word for "sea of reeds" was likely referring to a body of water with shallow shelves and thriving reedy marshes, rather than the deep Red Sea we know today. However, the name has stuck, and even the Septuagint scholars in the 3rd century BC identified the Red Sea as the site of the Exodus. The Red Sea's association with this historical event has made it a site of religious and cultural significance, and many visitors today travel to the Red Sea area to explore the region's history and heritage.

Early explorers and commercial routes

Early explorers played a crucial role in expanding the world's knowledge of the Red Sea and the surrounding region. Starting from the middle of the 2nd century BC, Arabs based in Alexandria set out to sail directly across the Indian Ocean and trade in the rich Indian market. The creation of the 'commander of the Red and Indian Seas' during the Egyptian administration marked a significant increase in regular commercial transactions with India. However, it was not until the discovery of the Monsoon winds that modes of navigation and vast expansion of trade took place. Furthermore, European exploration during the Age of Discovery in the 15th and 16th centuries saw a combination of circumstances lead to the search for new routes rather than new lands. The sea route east by south to Cathay initiated the first great enterprise of the Age of Discovery – the search for a sea route east by south to Cathay. Prince Henry the Navigator sent expedition after expedition throughout the 15th century to explore ore the coast of Africa, eventually reaching as far as the Cape of Good Hope. Early Portuguese explorers played a vital role in establishing commercial routes and mapping regions such as the Red Sea and the Indian Ocean, opening up new opportunities for lucrative trade and global expansion. As exploration and trade continued to develop, settlements and commercial centers such as Alexandria and Calicut emerged, establishing the Red Sea as a hub of commerce and activity for centuries to come. 

Settlements and commercial centers in the vicinity

The Red Sea is surrounded by several settlements and commercial centers that have played a significant role in the history of this body of water. One such example is the port city of Jeddah, which served as an important hub for trade routes between the Mediterranean Sea, the Red Sea, and the Indian Ocean from the seventh century CE onwards. Another notable city that emerged as a major center of trade in the region is Aden, located at the southern end of the Red Sea. This city played a crucial role in facilitating trade between India, Africa, and the Middle East, and was a key center for the transit of coffee, spices, and textiles. In addition to these major cities, other important settlements and trading posts are located along the coast, such as Berenice, Aila, and Leukos Limen, which were active during the time of the Ptolemies and Romans in Egypt. Today, many of these cities still retain their historical significance and continue to serve as vital hubs of commerce and trade in the region. From the ancient city of Jeddah with its bustling markets to the modern city of Port Sudan, the Red Sea continues to support a thriving economy fueled by international trade and commerce.
