Located in the area marked under the fabled ‘Bermuda Triangle’, the Sargasso Sea located within the North Atlantic Ocean is the only sea in the world that does not have a land boundary. Unlike other seas, its location is defined using ocean currents. It lies within a large system of rotating ocean currents called the Northern Atlantic Subtropical Gyre.
By compass directions, the Sargasso Sea’s western limit is marked by the Gulf Stream, the eastern by the Canary Current, the northern by the North Atlantic Current, while the southern limit is marked by the North Equatorial Current and the Antilles Current.
These borders flow in clockwise motion and are dynamic. They change season after season in accordance with the Azores High Pressure Center.
The Sea is named after the genus of free-floating seaweed called Sargassum, named due to early Portuguese encounters with the seaweed, who named it Sargazzo or kelp in Spanish. Sargassum is a form of free-floating seaweed or algae that is unique in the sense that it reproduces vegetatively in the high seas, unlike other forms of floating seaweed that reproduce and originate in the ocean-floor. As such, Sargassum mats are plentiful on the sea’s surface. On the surface, the Sargassum mats provide habitats for a variety of marine organisms such as turtles, which use their platforms for hatchlings to flourish (NOAA, undated).

The Sargasso Sea Alliance – a conservation partnership led by the Bermudian government – highlight three interdependent areas that place a case for scientific conservation efforts over the Sargasso Sea (Sargasso Sea Alliance, 2011). These include first, the unique ecosystem based on the floating Sargassum. Second, the area is a junction in the North Atlantic for migratory species that utilize the mats for food, reproduction and safety. Third, the unique conditions, the Sargasso Sea Alliance argues, are pertinent for research and require great vigilance.
The surface ecosystem is based upon two species of Sargassum that reproduce through fragmentation, and is different from all other varieties of seaweed. Golden-brown in colour, the floating mechanism is possible due gas filled bladders in the Sargassum. Sargassum provide critical habitats for many permanent and migratory species. The drifting of the sargassum makes it collect marine organisms, particularly invertebrates that attract other marine species towards the mats.
The Sargassum hosts more than 145 invertebrate species and over 127 species of fish. There is variance in this biodiversity owing to the season, location in the gyre and the age of the sea-weed. Larger marine species such as sharks and rays that prey on the spawning fish are also of great conservation value. Many spawning species represent rare species of marine life.
Many migrating species of fish such as Bluefin Tuna feed in the Sargassum Sea, which are exploited as a food source but are largely protected in the Sargasso Sea by the natural floating Sargassum.
Sargassum mats have been the source for many myths and legends over the centuries. They led many sailors to believe that their ships would be jammed and trapped in the seaweed in earlier times, which was accompanied with still waters and a lack of surface winds.
These myths had an important role in the conceptualization of the southwestern region of the Sargasso Sea as the Bermuda Triangle, as the passage in the ocean where ships would disappear. The floating Sargassum provides a natural barrier to fishing expeditions, and the Sargasso Sea was recently earmarked to be a world heritage site by the UN, and a report was published in 2016 in this regard (UN, 2016).
Darknet, also known as dark web or darknet market, refers to the part of the internet that is not indexed or accessible through traditional search engines. It is a network of private and encrypted websites that cannot be accessed through regular web browsers and requires special software and configuration to access.
The darknet is often associated with illegal activities such as drug trafficking, weapon sales, and hacking services, although not all sites on the darknet are illegal.
Examples of darknet markets include Silk Road, AlphaBay, and Dream Market, which were all shut down by law enforcement agencies in recent years.
These marketplaces operate similarly to e-commerce websites, with vendors selling various illegal goods and services, such as drugs, counterfeit documents, and hacking tools, and buyers paying with cryptocurrency for their purchases.
Anonymity: Darknet allows users to communicate and transact with each other anonymously. Users can maintain their privacy and avoid being tracked by law enforcement agencies or other entities.
Access to Information: The darknet provides access to information and resources that may be otherwise unavailable or censored on the regular internet. This can include political or sensitive information that is not allowed to be disseminated through other channels.
Freedom of Speech: The darknet can be a platform for free speech, as users are able to express their opinions and ideas without fear of censorship or retribution.
Secure Communication: Darknet sites are encrypted, which means that communication between users is secure and cannot be intercepted by third parties.
Illegal Activities: Many darknet sites are associated with illegal activities, such as drug trafficking, weapon sales, and hacking services. Such activities can attract criminals and expose users to serious legal risks.
Scams: The darknet is a hotbed for scams, with many fake vendors and websites that aim to steal users’ personal information and cryptocurrency. The lack of regulation and oversight on the darknet means that users must be cautious when conducting transactions.
Security Risks: The use of the darknet can expose users to malware and other security risks, as many sites are not properly secured or monitored. Users may also be vulnerable to hacking or phishing attacks.
Stigma: The association of the darknet with illegal activities has created a stigma that may deter some users from using it for legitimate purposes.
