Normally, seas and oceans fall in the same boat, collectively known as the World Ocean; however, there are a few differences between the two. Seas refer to smaller regions of the oceans, either disconnected or surrounded entirely or partially by landmass, and are shallower in terms of depth. They are usually found along the coasts of the continents or connected to the ocean in some form, such as a strait.
What makes seas stand out from oceans is their variety. There is a large number of seas on the earth’s surface, many of the bearing unique characteristics. For example, the waters of the Black Sea have little oxygen and the waters were able to preserve a large number of ancient shipwrecks for scientists to study. The Red Sea has the saltiest water in the world, a result of low precipitation in the region and little to no drainage from other sources of water into the area. A more extreme example is the receding Dead Sea, one of the smallest and shallowest bodies of water in the world. Its extreme saline water can form deposits of salt columns and prevents normal life from existing there.
Part of the Mediterranean Sea, the Adriatic Sea is actually a body of water that separates the Italian Peninsula from the Balkan Peninsula. The sea also separates the Apennine Mountains from the Dinaric Alps. The Adriatic is bordered by many different countries including Italy to the west, Croatia to the east, as well as Slovenia, Bosnia and Herzegovina, Montenegro, and Albania. There are many substantial rivers that join the Adriatic Sea including the Reno, Po, Adige, Brenta, Piave, Soc, Neretva, and Drin.
The Adriatic Sea is a name that has been known throughout the ages. The Adriatic was actually named for the colony of Adria, and originally it was only the upper most portion of the sea that would bear this name. The Adriatic Sea was a fitting name as the term Adria means water or sea. The sea is often misused to identify the Sea of Sicily or the Gulf of Corinth, though these are separate and distinct bodies of water.
The Adriatic Sea has been used as a way to transport goods from one region to another. Because it is on the coastline of so many different countries the Adriatic is known by many different names. For instance, it is known as the Mare Adriatico in Italy, the Jadransko more in Croatia, and the Deit Adriatik in Albania.
The Adriatic Sea spans about 480 miles in length and is 100 miles across. The total surface area is about 60,000 square miles, with the northern part of the sea being very shallow, in fact much more shallow than the rest. The deepest parts are west of Durres, where the depth is 1,460 meters. The mean depth of is 240 meters.
The Adriatic sea is somewhat dangerous to navigate during the winter months. The bura is what the northeast wind is called on the sea and they make traveling via boat quite dangerous. There is also the Jugo, the southern wind, which will bring rain. In addition there is the maestral, the western wind, which is wanted in the summer as it brings clear weather. There is very little tide which makes a great tourist location on all coasts.
The west coast of the Adriatic Sea is usually quite low and then turns into marshy land and lagoons toward the northwest. The eastern coast of the is usually much more rocky and bold and features many islands. There are many different islands, most of which are quite long and narrow and will rise more than a hundred feet in the water. The coasts of the Adriatic Sea are in stark contrast to one another with the Italian coast being clearer weather wise with the Croatian coast having the clearer water.
Located between the Balkan and Anatolian peninsulas, the Aegean Sea is actually a arm of the Mediterranean Sea. The Aegean can actually be found most easily between Greece and Turkey and is joined to the Marmara Sea and the Black Sea in the north.
The Aegean Sea is home to a few islands that include Crete and Rhodes. Interestingly, the sea was originally known as the Archipelago, and while the term is still used, the Aegean generally referred to as a sea today.
The Aegean Sea is a sea that has many explanations where its name is concerned. Many have said it was named after the Greek town of the Aegae, while others have said that it was named after the queen of the Amazons, and others claim the Aegean was given its name after the Aigaion, which was a sea goat.
Of course, there is also the theory that the Aegean Sea was named after Aegeus, who was the father of Theseus, who drown himself in the sea when he was told that his son had died. Most today give more credit to the sea being named after the Greek word aiges, which means waves. The Bulgarians also take credit with naming the Aegean Sea as it translates into “white sea” and legend has it that the Bulgarians found the Aegean a great way to travel when compared with the Black Sea.
The Aegean Sea has a maximum depth of 11,624 feet and covers more than 214,000 kilometers in area. The sea has many different islands, which are actually just continued mountains on the mainland. For this reason, navigating around the islands in the Aegean can be quite difficult. While some of the islands have safe harbors or bays, many are difficult to get to because the waters can be shallow near shore, there are rocks and volcanic materials, and many of these things cannot be seen through the water.
The Aegean Sea actually has 1,415 islands with 1,395 of them belonging to Greece and two belonging to Turkey. The islands have been an area of tension between Turkey and Greece, with both of them wanting to lay claim to the water as well as the islands in the Aegean. The conflicts over the sea and islands is something that has been ongoing since the 1970s, resulting in continued strained relations.
Despite conflicts and legends about the Aegean Sea both the people of Turkey and Greece and those that live near continue to use and enjoy the water and the islands to the fullest extent possible. The Aegean is known for cool and calm waters, many fishermen claim that the Aegean Sea is one of the most enjoyable seas to travel through.
he Arabian Sea is actually a portion of the Indian Ocean, bordered by India to the east, Pakistan and Iran to the north, the Arabian Peninsula to the west, and to the south the western coast of Sri Lanka.
The Arabian Sea is bordered by so many different areas; it is well known in this region of the world and provides entertainment, work, and beauty for all who live near.
The Arabian Sea has a width of about 1,500 miles and the maximum depth of the is about 15,300 feet deep. The deepest part is located at about the same latitude as the southernmost tip of India. The sea has many different rivers that flow into it, with the largest river flowing into the Indus River, which is also known as the Sindhu River.
There are other rivers that flow into the Arabian, including Netravathi, Sharavathi, Narmada, Tapti, Mahi, and many different rivers of Kerala, which originate in India. The sea has two different coasts, and the coasts are known as the Konkan Coast, which is the coast of central India and the Malabar Coast, which is the coast of southern India.
The Arabian sea has two very important branches, which include the Gulf of Aden, which is in the southwest and connects to the Red Sea through the strait of Bab-el-Mandeb. The sea also branches off into the Gulf of Oman, which is to the northwest and connects to the Persian Gulf. In addition there are other smaller offshoots that are of importance which include the Gulf of Cambay and the Gulf of Kutch, located on the Indian cost.
The Arabian Sea is known for many things but one of the things that just about everyone connects with is that it is a trade route for Indian people as well as for people from all over Europe. The sea has been used throughout history for trade, to get things from one place to another.
There are tales of sailors who spent most of their lives living on the Arabian Sea. The great thing about the Arabian is that it connects to other bodies of water, making it a great way to get just about anywhere you want to go in the world for trade. The Egyptians actually built shallow canals that would lend themselves to easy trade, making it obvious that the trade routes are important to many different cultures all over the world.
The Baltic Sea can be found in Northern Europe. A salt water sea, surrounded by the Scandinavian Peninsula, the mainland of Europe, as well as the Danish islands. The sea is interesting because it is artificially linked to the White Sea through the White Sea Canal and is also linked to the North Sea by the Kiel Canal. In addition, the Baltic is also surrounded by gulfs, such as the Gulf of Bothnia to the north, the Gulf of Finland to the northeast, and the Gulf of Riga to the east. The Baltic drains, though other sources, into both the North Sea and the Atlantic Ocean.
The name Baltic Sea was given to waters in the eleventh century by a man named Adam of Bremen. There is not any concise meaning known, but many speculate that the sea was named such after the German word for belt, or the Latin word balteus, which means belt. What is known is that Adam of Bremen likened the Baltic Sea to a belt because of the way the sea stretched through the land. There is a lot of speculation about the basis of the name, with many different languages contributing to the speculation.
The Baltic Sea is known by many names such as the East Sea, the West Sea, with the Baltic Sea being the most used and the most understood. The sea will be called by many different names depending where in the world you are from, but when you look at a map the it is usually labeled as the Baltic Sea, regardless of what it is called
The basin that the Baltic Sea sits in was created by glacial erosion and today the sSea is about 1,000 miles long and 120 miles wide and has an average depth of about 180 feet deep. The deepest point is about 1,506 feet deep. The surface area is an impressive 145,522 square miles and the Baltic has a volume of 5,040 cubic miles.
The Baltic Sea is interesting because 45% of its surface area is covered with ice, and the remaining areas never freeze, even during the winters (with the exception of shallow or sheltered bays). The sea experiences the most ice coverage during the moths of February and March and on average the ice is about 70 centimeters thick with the ice becoming thicker the further south that you go. Interestingly, in recent years the sea has seen a lot less ice coverage, with very little of the surface being frozen in the winter of 2007. Many people explain the lack of ice on in recent years with global warming.
Located in what is known as the Aleutian Basin, the Bering Sea is located in the Pacific Ocean. The sea covers 775,000 square miles and has Alaska to the east and northeast, Siberia to the west, the Alaska Peninsula to the south. The Bering is bordered by the Bering Straight to the north, which is what separates the sea from the Arctic Ocean. In addition, the sea is kept separate from the Gulf of Alaska due to the Alaska Peninsula and the Aleutian Islands.
The Bering Sea is home to many islands, including Pribilof Islands, Bering Island, St. Lawrence Island, Diomede Islands, King Island, St. Matthew Island, and Karaginsky Island. In addition, there are many different submarine canyons, 16 of them in fact the largest of them Zhemchug canyon.
The Bering Sea is home to many different types of wildlife. In fact, many state that it has some of the most diverse and interesting wildlife of any body of water. Some of the species that found here are: the bowhead whale, the blue hale, fin whale, sie whale, humpback whale, the sperm whale, and a very rare species, the Northern right whale. Of course, the Bering Sea is also known to provide a home to walrus, sea lions, fur seals, beluga whales, orcas, and polar bears.
In addition, there are more than 30 different species of sea birds that live in and around the Bering Sea, with 20 million birds breeding near each year. There are many different types of fish that are native to the Bering Sea as well, including salmon, walleye Pollock, red king crab, pacific cod, yellowfin sole, and sablefish. The sea reportedly has 419 known species of fish in the waters.
The Bering Sea is known for its fisheries. Many fisheries, such as King Crab, find that it’s a profitable place to do business. There are many fisheries that work here exclusively, and many have begun to worry about the eco system. The affects of over fishing and global warming are something that many people are watching very closely. With rising water temperatures and continued fishing in the ecosystem is definitely being threatened.
A lot of the problem is that the ecological system, or food web, of the Bering Sea is not very well understood. Fisheries need to be certain that they are not over fishing so that they can keep providing consumers with the variety as well as ensure their longevity in the fishery business.
The Bering Sea is a great place to travel as tourists can see many different types of wildlife, some that are unique to the area. For fisheries, it is a dream come true because of the wide variety of fish that can be caught, and for endangered species the sea has been a haven. All 775,000 square miles of deep water basin in the Pacific Ocean is unique in many different ways.
A destination of millions each year, the Caribbean Sea is known to be tropical sea. The sea is located in the Western Hemisphere and is a part of the Atlantic Ocean and is southeast of the Atlantic Ocean. The Caribbean is actually a Mediterranean sea and it covers what is known as the Caribbean Plate, which is surrounded by South America to the South, Mexico the South and West, and to the North by the Antilles, the Greater Antilles, Cuba, Hispaniola, Jamaica, and Puerto Rico. Known collectively as the Caribbean, the Caribbean Sea and the islands of the West Indies are a popular vacation spot. The area offers fun, warmth, beauty, and a way of life for many people all around the world.
The Caribbean Sea is one of the largest salt water seas in the world with a total area of 1,063,000 square miles and a depth that is more than 25, 220 feet below sea level. The deepest point is located at the Cayman Trough, which is between Cuba and Jamaica. The Caribbean Sea has many differed gulfs and bays including the Gulf of Gonave, Gulf of Venezuela, Gulf of Darien, Golfo de los Mosquitos, and the Gulf of Honduras with each area offering something just a bit different.
The Caribbean Sea was given its name by the Caribs, which was one of the American Indian groups that were located in the region during the 15th century. Christopher Columbus gave the Caribbean Sea the name of the Antillas or Sea of the Antilles, and this is another name that the sea is known by today. It was Christopher Columbus that made the waters known, because before this the sea was truly unknown to Eurasia. Once found the Caribbean quickly became a great way to travel from continent to continent as well as a way to trade with others.
The Caribbean Sea has become popular since Columbus and is home to 22 island territories. The sea borders 12 additional continental countries. The Caribbean and surrounding areas offer an appealing backdrop to many vacations because of the year around nice temperatures, sunshine, and tourism cultures that the sea offers those that that travel.
The Caribbean Sea provides a sanctuary to more than 29% of the world’s coral reefs, having 20,000 square miles of coral reefs to boast. Most of the reefs in the Caribbean are located off of the islands and the Central American coast. In recent years the Caribbean Sea temperatures have risen considerably, which means that the Caribbean Sea is in danger of losing it’s well known Caribbean Sea reefs.
When the Caribbean Sea has temperatures of more than 85 degrees Fahrenheit some of the plants begin to die off, which throws the entire ecosystem into a tail spin. It’s in the best interest of those that live on and near the Caribbean to preserve the reefs as they account for a lot of the tourism and economy funds that come into the shores. With weather in the region being influenced by the Gulf Stream and Humboldt ocean currents, only time will tell how effective current efforts to reduce global warming and the destruction of the ecosystem will be.
The Caspian Sea is known to be the largest land enclosed body of water on Earth. Depending on where you go and whom you talk to, the sea is known as the world’s largest lake or the world’s largest sea. The sea covers an expanse 143, 244 square miles and has an impressive volume of 18,761 cubic miles.
The Caspian Sea is unique because it has no streams that flow out from it, so it is known as an endorheic body of water. The deepest portion of the Caspian that has been measured was more than 3,363 feet deep. While the water is salty, it has a salinity of just 1.2%, which is only about a third of most seawater. Those that first discovered the Caspian thought it was actually a sea because of the salinity.
The Caspian Sea was named after the Caspians and the is now known to be what is left of the Tethys Ocean, as is the Mediterranean and Black Seas. The Caspian became landlocked due to the drifting of continents about 5.5 million years ago. Today the Caspian is located on the coasts of Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. It is known to be the largest body of water in this region of the world, accounting for as much as 44% of the lacustrine waters of the world.
The Caspian Sea is divided into three distinct sections which s the Northern, the Middle, and the Southern Sea. The Northern is actually the Caspian shelf, and is known to be one of the shallowest areas, holding less than one percent of the total volume, with just five to six meters in depth on average. The Middle Caspian is where the waters start getting noticeably deeper, as deep as 190 meters and the Southern Sea is where the water is the deepest with depths of over 1,000 meters. It is the Middle and Southern Caspian Sea that account for most of the volume.
While there is not outflow from the Caspian Sea there are more than 130 inflow rivers, with the Volga River being the biggest. The Caspian is home to a few small islands, with most of them being located in the Northern Sea with all of the Caspian islands having an overall land area of 2,000 square kilometers.
Neighboring the Northern Caspian Sea is depression, which is a very low-lying region that is 27 meters below sea level. In addition, there is the Central Asian steppes that run along the northeast coast of the sea and the Caucasus mountains are along the western shore. The lands and the temperatures in these regions vary widely with low planes and mountainous regions, and therefore there is a large diversity of living things in and around the sea.
The Dead Sea is actually a lake that is located between Israel and Jordan. The sea is a natural wonder for many reasons, including the fact that it is the deepest hypersaline lake in the world. In addition, the Dead Sea is the world’s second most salty body of water in the world with it being 8.6 times saltier than the ocean, containing 31.5% salt. Also noteworthy because it is 1,378 feet below sea level and the shores are the lowest point of dry land on Earth.
The Dead Sea is actually what is called an endorheic lake and it is located in the Jordan Rift Valley. The sea is thought to have been created through flooding of the Mediterranean Sea and over time it stopped flooding and the remaining water became a lake. The sea has just one major water source and that is the Jordan River with no outlet streams.
The Dead Sea is known to many people because it offers good temperatures year around with summer temperatures being between 90 and 102 degrees Fahrenheit and winter temperatures between 68 and 74 degrees. Remarkably, during the winter the temperatures are higher than the land temperatures and in the summer the water temperatures are lower than the land temperatures. The warm climate and reported therapeutic benefits attract many to the area for treatments such as climatotherapy, heliotherapy, and thalassotherapy. The chemical composition of water, including its high salt levels, have proven to be very therapeutic.
The Dead Sea got its name because not many animals or plants are able to live in the water. The sea has a high salinity level and because of this water plants and fish are not able to survive. Even bacteria is available in very limited numbers in the Dead Sea due to the high salinity levels. While the sea cannot support much in the way of sea life, it provides a unique experience for those that enter the water. Due to the high salinity and other chemical aspects of the water it has natural buoyancy to it and people can actually float, not unlike the Great Salt Lake in Utah.
The Dead Sea is known for having turned red in 1980. This was after a period of intense rains and the salinity dropped, allowing for a specific type of algae, known as Dunaliella to come to life and thereby sustain a halobacteria known to be red in color, which caused the sea to turn red in color. The sea was only red for a short time and since then the bacteria have not come back to life in large enough colors to cause a change.
In addition to turning red, the Dead Sea is also known to produce asphalt, in fact when one swims in they may come across small black pebbles in the water.
Covering more than 900,000 square miles, the Mediterranean Sea is a sea of the Atlantic Ocean. The Mediterranean is unique because it is almost completely surrounded by land, including Europe to the North, African to the South, and Asian to the East. Connected to the Atlantic by the Strait of Gibraltar and it is just nine miles wide. Often referred to the as Eurafrican Mediterranean Sea or even the European Mediterranean to avoid confusion with other bodies of water referred.
The Mediterranean Sea was name derives from the Latin word Mediterraneus, which means, “middle of the earth”. This name was fitting because the Romans believed that the Mediterranean was in fact the middle of the earth. Of course, the Sea has been known by many other names such as Mesogeiso by the Greeks, Hinder Sea, Western Sea, and also the Sea of the Philistines, and the Great Sea.
Whatever the Mediterranean Sea was called it has been known by many cultures for ages because it provided a way to trade, colonize, to fight wars, and even provided food and work. The Sea is a central part of life dating back centuries in the Mediterranean Sea regions of the world. Twenty-one different countries border the Mediterranean Sea and the Mediterranean Sea has brought many things to each of these regions.
The Mediterranean Sea is known to have many different islands throughout its waters including Cyprus, Crete, Euboea, Rhodes, Lesbos, Chios, Kefalonia, and Corfu. Additional islands in the Mediterranean include Sardinia, Corsica, Sicily, and Malta. Of course, that is not all as you will also find Ibiza, Majorca, and Minorca in the western Mediterranean Sea.
Due to the location of the Mediterranean Sea the climate is generally known to be quite wet with cold winters and hot and dry summers. Many of the crops that are grown in and around include olives, grapes, oranges, tangerines, and cork.
The Mediterranean Sea is most well known for its deep color. The Sea has very limited tides for a body of water this size and that is due to the fact that it has a very small connection with the Atlantic Ocean. Evaporation is excessive, especially in the eastern half of the sea, which means lower water levels and a decrease in salinity levels in this portion of the water.
The Mediterranean Sea is on average, about 4,920 feet deep with the deepest recorded depths about 3.267 miles. The coastline of the Mediterranean Sea spans an impressive 28,600 miles and is broken into three distinct parts by experts and is often referred to in these parts as the Eastern Mediterranean, the Central, and the Western Sea. Each area of is known for its different characteristics such as different water depths, salinity levels, water flow, and even water temperature and geological finds.
Global warming has had an impact of the Mediterranean Sea and has caused water levels in to decline rapidly over the years. In fact, wild life that makes its way into the Mediterranean from the Atlantic often does not survive as the waters are not as nutrient rich, and those that do have to adapt to the differing water conditions.
Over the years, the actual Red Sea has become one of the very popular holiday destinations in the world Apart from being a convenient location that provides comfortable access to many areas of the Middle Eastern; it is also among the best diving as well as snorkelling websites in the world. Whenever paired with countless historical attractions, state of the art visitor facilities, as well as hundreds of amusement venues, you are able to almost suppose the Red Sea as the visitor playground around the globe. Therefore, if you’re planning a vacation, a family holiday, or a business travel, you can rest assured which choosing a Red Sea location will suit you requirements.
The Red Sea had been formed approximately. 25 zillion years ago once the African as well as Asian/s plates began to move aside. It is constantly on the wide for a price of about 1-2 centimetres per year. The actual Red Sea contains a lot more than 1, thousand species of seafood and has more than two thousand kilometres associated with fringing reef, which makes it one of the most bio-diverse oceans in the world. Severe heat in this area results in an immediate rate associated with evaporation which ends in a higher concentration of sodium. This makes the actual Red Sea among the saltiest physiques of drinking water on Earth.
The actual Egyptian Red Sea happens to be known as probably the most colourful oceans of the world. The actual geological movements of history created a distinctive condition which permitted sea life to develop in a wonderful variety of corals as well as reef fish resulting in the largest possible selection of colours. Due to the warm weather and the fantastic opportunities with regard to diving the actual Red Sea along the Silk Coast includes a become a Mecca associated with resort metropolitan areas – Sharm becoming the earliest but then Hurghada a city which has risen from the small town to a big city during the last few years. A number of other resort metropolitan areas are developing along the coastline and have gain popularity destinations especially for Men and women who can right now get affordable charter plane tickets direct to those cities across the Red Sea coast.
The actual Red Sea also consists of many just offshore reefs including a number of true atolls. Most of the unusual just offshore reef structures defy traditional (i.e. the. Darwinian) coral saltwater classification strategies, and are generally related to the higher levels of tectonic exercise that define the area. The actual special bio-diversity of the region is identified by the Silk government that set up the actual Ras Mohammed National Recreation area in 1983. The guidelines and rules governing el born area protect nearby marine existence, which has be a major pull for scuba diving enthusiasts.
Blowing wind is the power in the Red Sea with regard to transporting the fabric either because suspension or even as bed load. Blowing wind induced power play a huge role in the Red Sea within initiating the entire process of resuspension of base sediments and move of supplies from websites of throwing to websites of funeral in quiescent atmosphere of depositing. Wind produced current dimension is therefore essential in order to look for the sediment dispersal design and its part in the erosion as well as accretion of the seaside rock publicity and the immersed coral mattresses.
Sea of Cortez
Known by many different names, the Sea of Cortez separates the Baja California Peninsula from the mainland of Mexico. The Sea is known as the Gulf of California as well as the Mar de Cortes, the Mar Bermejo, or the Gulfo de California. While there are many different names, they all refer to this same body of water. When you look at just about any modern map the Sea of Cortez is usually listed as the Gulf of California.
The Sea of Cortez has been a body of water for about 5.3 million years ago, and the result was a redirection of the Colorado River. There are many rivers that flow into the sea including the Mayo, Fuerte, Sinaloa, Sonora, and the Yaqui.
The Sea of Cortez was something that started occurring more than 12 million years ago. While the actual Sea of Cortez wasn’t in existence 12 million years ago, it was during this time that the North American Plate shifted, laying the foundation. The sea could have extended as far down as Indio, California, but a huge delta was created by the Colorado River, which effectively blocks the sea from flooding both the Imperial Valley and the Mexicali Valley. Throughout the Sea of Cortez there is volcanism, for instance, with Isla of Tortuga where there is still volcanic activity occurring today.
While the Sea of Cortez is actually quite narrow it is home to a very extensive ecosystem. Many different creatures migrate to the sea each year. Some of the sea life that can be found are the humpback whale, California gray whale, manta ray, and the leatherback sea turtle.
The Sea of Cortez is also known for its commercial fishery offerings. In fact, there have been some commercial fisherman who have reported schools of tuna that have spanned more than 100 miles. Unlike a lot of waters where there are commercial fisheries, the Sea of Cortez appears to be stable, offering the ability for more fisheries to open up. While the wildlife appears to be stable there have been some changes, such as a reduction in flow from the Colorado River, which will eventually have a negative impact on fisheries.
The Sea of Cortez has more than 900 islands, with some of them being a bit bigger. Two of the larger islands are the Isla Angel de la Guarda and the Tiburon Island. It is around these islands that many different species of wildlife can be found. The islands are also the nesting grounds for many different marine mammals and seabirds. The Cortez waters are where many different species breed, feed, and nurse their young. Two of the leading markets are sardines and anchovies. While currently stable, there is some concern that the sea will eventually have problems in addition to some pollution including over fishing as well as bottom trolling, which damages shellfish and the basin.
The term Seven Seas has been used throughout history and over time the meaning of this word has changed. Generally speaking, when the is used it refers to a specific set of seas or to the huge amount of water that is out there to sail on.
The term the Seven Seas will mean different things to different people and you will most often see in literature. In medieval European literature the Seven Seas is was referring to Adriatic Sea, the Aegean Sea, the Arabian Sea, the Black Sea, the Caspian Sea, the Indian Ocean, the Irish ea, the Mediterranean Sea, the North Sea, the Persian Gulf, and the Red Sea. When you hear the term the Seven Seas many people have to stop and question which of the seas this includes as the International Hydrographic Organization qualifies 100 different bodies of water as seas.
Many claim that the term the Seven Seas is something that is newer and has origins in Greece and Rome. The term has been found in literature since 2300 BC. In fact, they are referred to around this time in Hymn 8 of the Sumerian Enheduanna to the goddess Inanna.
The term the Seven Seas was also found in a ninth century AD Muslim piece of writing in which the seas are clearly defined. In this writing they referred to the Persian Gulf, the Gulf of Khambhat, the Bay of Bengal, the Strait of Malacca, the Singapore Strait, the Gulf of Thailand, and the South China Sea. This Arabian version of the Seven Seas is obviously different than was thought in Rome and Greece.
In Venice the term the Seven Seas usually just meant that one had sailed through the area lagoons and in Rome this usually meant that one had sailed on seven different bodies of water, and therefore possessed better than average sailing skills. As you can see, the term means different things in different places, and the has been redefined over time. The term today usually is found in stories in books, that are passed down from generation to generation.
Today the Seven Seas are defined differently than they once were, the North Pacific Ocean, the South Pacific Ocean, the North Atlantic Ocean, the South Atlantic Ocean, the Southern Ocean, and the Arctic Ocean, which are not actually seas, but portions of different seas. As you can see, the Seven Seas are different than when the term was first used in the past, and the definition of may very well change in the future.
