I bet once we find it’s worth money it’ll be harvested past sustainability

The Florida Keys and mainland South Florida are well known for the high levels of Sargassum covering their shores. Sargassum or gulfweed was observed by Columbus. Although the seaweed acquired a legendary reputation for covering the entirety of the Sargasso Sea, making navigation impossible,[4] it has since been found to occur only in drifts.[5]Sargassum (F. Sargassaceae) is an important seaweed excessively distributed in tropical and subtropical regions. Different species of Sargassum have folk applications in human nutrition and are considered a rich source of vitamins, carotenoids, proteins, and minerals. Many bioactive chemical compounds that are classified as terpenoids, sterols, sulfated polysaccharides, polyphenols, sargaquinoic acids, sargachromenol, and pheophytin were isolated from different Sargassum species. These isolated compounds and/or extracts exhibit diverse biological activities, including analgesic, anti-inflammatory, antioxidant, neuroprotective, anti-microbial, anti-tumor, fibrinolytic, immune-modulatory, anticoagulant, hepatoprotective, and anti-viral activities.[7]

This seaweed reminds me of when my aquarium didn't have stable conditions where there was too much fish waste (nitrogen) in the water causing algal blooms, so I guess the oceans are now filthy but the seaweed just as the algae in my aquarium is a blessing in disguise because they suck up the waste for their own growth with makes in turn more waste get to be absorbed.

Seaweed. This is so cool. By the way, I have difficulty communicating because I had a stroke in Broca’s area, the part of the brain that controls speech. 2/8/2021 but I lived again. (My wife helped me compose this.)

Put a solar thermal array on the deck of an old super tanker and float around converting excess seaweed to pyrolysis oil for biodiesel production. The carbon char byproduct, if not suitable for agricultural use on land, can go back into the ocean and will stay in that form for centuries if its lifespan if terra preta is any indication.

Feeding the abyss? What effect will that have? Similar to a storm blowing a forest hillside into the depths.

Seaweed / kelp is becoming an important material in the blue economy... harvest it. Seaweed / kelp has numerous uses and may be suitable for a whole host of uses, such as a fertlizer, prevent methane generation in cows, as a construction material, as a replacement for plastic etc etc.

I wish it made good fertilizer like kelp does. Its a shame. Maybe there is a way to clean it, what are the arsenic levels if you wash it, does it make a difference? Where does the arsenic come from? What if you burn it, making biochar, or perhaps a nutrient rich ash.

These uncontrollable blooms are directly impacted by humans and agricultural production. Therefore, they should also be taken into consideration when dealing with waste by-products of agriculture. I don't think investing in a robot to sink it to the bottom of the ocean, is even feasible, but also there are lots of ways we can first learn to reuse this very directly human waste back into our economy.

very cool!

Maybe we can keep it from getting ashore in certain areas in the first place

I see similarity in Sargassum and Pikes problem in America. They hv economic value but there are few to harvest it.

They are talking about utilizing Sargassum to produce biofuels.

My instinct says that this seaweed is possibly a natural adaptation to help heal the damage we have done to the ocean. In nature nothing happens without purpose

i remembers see it come to the coast by the tons and wee use to collect it for sale

What about anaerobic digestion for bio-gas ,that would give it value?

Can it be turned into paper?

collect from beaches,spread in deserts, should provide nutrients enough to start life there again.

5000 miles wide is on its way to Florida

They can harvest it and sell it, it'll no only aid the problem but help their economy. it could be used as compose, a source of fuel, dried and eaten; after they clear it of any harmful chemicals of course. I really hope they can find a solution Barbados and the caribbean is so beautiful that everyone should visit at least once in their life, I hate seeing this problem affecting the wonderful scenery of the caribbean.
