What gyre is the Sargasso Sea in?
Northern Atlantic Subtropical Gyre
While all other seas in the world are defined at least in part by land boundaries, the Sargasso Sea is defined only by ocean currents. It lies within the Northern Atlantic Subtropical Gyre.
How much of the North Atlantic does the Sargasso Sea cover?
two thirds
Over one thousand miles wide and three thousand miles long, the Sargasso Sea occupies almost two thirds of the North Atlantic Ocean. Within the sea, circling ocean currents accumulate mats of Sargassum seaweed that shelter a surprising variety of fishes, snails, crabs, and other small animals.
Why is part of the Atlantic Ocean called the Sargasso Sea?
The Sargasso Sea is named for Sargassum, a holopelagic, golden drift algae that can aggregate to form extensive floating mats on the surface of the ocean. Dr. Sylvia Earle has called it “the golden rainforest of the ocean.”
What keeps the waters of the Sargasso Sea from mixing with the rest of the Atlantic Ocean?
The unusual features of the Sargasso Sea result in part from its great depth, which averages almost 5 km. The sea’s location plays a role as well. It is surrounded by fast moving currents – the Gulf Stream and the North Equatorial Current – that keep its water from mixing with the rest of the Atlantic Ocean.
Why is the Sargasso Sea important?
“The Sargasso Sea is… of great biological importance as a place that provides essential habitats for nurturing many iconic marine species such as whales, tunas, swordfish and marlin. It is the place where turtles spend their ‘lost years’ using the Sargassum as a safe refuge within which to grow .”
What is a gyre in the ocean?
A gyre is a large system of rotating ocean currents. The ocean churns up various types of currents. Together, these larger and more permanent currents make up the systems of currents known as gyres. Wind, tides, and differences in temperature and salinity drive ocean currents.
What does Sargasso mean?
Definition of sargasso 1 : gulfweed, sargassum. 2 : a mass of floating vegetation and especially sargassums.
What forms the North Atlantic gyre?
The North Atlantic gyre is formed by the North Equatorial Current flowing into the Gulf Stream along the east coast of the United States. The Gulf Stream merges into the North Atlantic Current to move water towards Europe, which then becomes the Canary Current as it moves south to join the North Equatorial Current.
Why is the North Atlantic gyre important?
The gyre traps anthropogenic (human-made) marine debris in its natural garbage or flotsam patch, in the same way the North Pacific Gyre has the Great Pacific garbage patch. At the heart of the gyre is the Sargasso Sea, noted for its still waters and quite dense seaweed accumulations.
Can you swim in the Sargasso Sea?
Although going for a swim in the ocean is not an uncommon pastime, we understand that the notion of swimming through a forest of seaweed may seem like a daunting task. However, you have nothing to worry about when it comes to meeting Sargassum in the water.
How do the waters of the Sargasso Sea differ from the waters of the rest of the North Atlantic?
The Sargasso Sea (/sɑːrˈɡæsoʊ/) is a region of the Atlantic Ocean bounded by four currents forming an ocean gyre. Unlike all other regions called seas, it has no land boundaries. It is distinguished from other parts of the Atlantic Ocean by its characteristic brown Sargassum seaweed and often calm blue water.
Where is the North Atlantic gyre?
The North Atlantic Gyre begins with the northward flow of the Gulf Stream along the East Coast of the United States. The Gulf Stream is the western boundary current of the gyre. The gyre then becomes the North Atlantic Current, which flows across the North Atlantic to Europe.
How is the North Atlantic gyre formed?
Where is Sargasso Sea located?
the North Atlantic Ocean
Sargasso Sea, area of the North Atlantic Ocean, elliptical in shape and relatively still, that is strewn with free-floating seaweed of the genus Sargassum.
Where is North Atlantic gyre?
Is the North Atlantic gyre warm or cold?
Characterized by warm temperature and high salinity, the North Atlantic Current is sometimes concealed at the surface by shallow and variable wind-drift movements. The current often mixes with northern cold polar water to produce excellent fishing grounds near islands and along the coast of northwestern Europe.
Are there sharks in the Sargasso Sea?
A number of species of sharks and rays inhabit or migrate through the Sargasso Sea including whale sharks, tiger sharks, manta rays and spotted eagle rays (Hallett 2011, unpublished).
