Scientists are predicting a record sargassum bloom in 2023. It’s already starting to wash up on beaches in Florida and the Caribbean and cause a stink.

Our recent report identified how to make aquaculture – including shrimp and seaweed farming – more sustainable for Indonesians and for the environment.
Seaweed is in the spotlight for so many reasons. It all sounds too good to be true. So can this wonder weed live up to expectations and fulfill its promise to save us from ourselves?
The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
The abundance, versatility and quality of seaweed from the St. Lawrence makes this resource a real asset for Québec. We must now integrate it into our kitchens.
Rotting seaweed has plagued the Caribbean, Gulf of Mexico, US and West African coasts for a decade. So we’ve developed a new approach to turn what’s now rubbish into green electricity and fertiliser.
Seaweed was thought to be a vital tool in the fight to slow climate change. But it turns out seaweed ecosystems may be a natural source of carbon dioxide – and not a sink.

Huge blooms of brown seaweed have fouled Florida and Caribbean beaches almost every year over the past decade. They originate in Africa and South America. and are fueled by human activities.
Cow burps and farts are no joke – they’re a big factor in climate change. A new study shows that daily seaweed supplements could tame this major methane source while saving ranchers money.
The success of Indonesia’s seaweed industry is also closely linked to the ability of Indonesian seaweed farmers to work around extreme seasonal variations in seaweed growth rates.

Awareness is increasing about foods like lab-grown meat, insects and seaweed. These foods may help address environmental challenges, but it’s important to be aware of both the costs and benefits.

Small wounds can usually heal by themselves, but larger wounds can be a problem. With a little help from a seaweed we can help the body regenerate new blood vessels.

Marine heatwaves, like their land counterparts, are growing hotter and longer. Sea species in southeastern Australia, southeast Asia, northwestern Africa, Europe and eastern Canada are most at risk.
