I had never heard of the Sargasso Sea until an old man on the beach told me about it last week. Apparently, it is the only sea that is not in contact with any type of land. It is located in the middle of the North Atlantic, and the Bermuda Triangle is in the center of the Sargasso. 
It is bounded on the west by the Gulf Stream, on the North by the North Atlantic Current, on the east by the Canary Current, and on the south by the North Atlantic Equatorial Current. It is named after the Sargassum seaweed which tends to float around in the middle of the Sargasso. This is the destination of most of the sea turtles that hatch from our Florida coastline each season.  The seaweed provides a good resting place for the baby turtles until they grow up.
The sea seems to have been known by the early mariners, as a poem in the 4th century describes a large portion of the Atlantic as being covered by seaweed. The Sargassum is not a threat to shipping, and the historic incidents of sailing ships being trapped are due to the often-calm winds of the horse latitudes [a belt of calm air and sea occurring in both the northern and southern hemispheres between the trade winds and the westerlies].
The American conger eel hatches in the Sargasso, then they migrate to Europe, and North America.  They return to the Sargasso later in life to mate. 
The Sargasso is best known for being one of the world’s largest accumulation of non-biodegradable floating plastic trash cans in the world. Several nations have joined together to clean up and save the Sargasso.  Think about it the next time you throw a plastic container away.  Seems like we could be better stewards of this precious planet!
