Seaweed might be the greatest untapped resource we have on this planet, writes Vincent Doumeizel. Opinion: Seaweed is nutritious, not slimy. Eating it could save the world.
“The bull kelp forest that runs along the Oregon coast is a stunningly beautiful and vitally important ecosystem,” says Alanna, who studied biology with a focus on marine science at Oregon ...
They produce 25–45% of the total primary production of organic material in the oceans, [58] [59] [60] owing to their prevalence in open-ocean regions when total phytoplankton biomass is maximal. [61] [62] Diatoms are enclosed in protective silica (glass) shells called frustules. They are classified by the shape of these glass cages in which ...
Marine biogenic calcification is the production of calcium carbonate by organisms in the global ocean.. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues.
Seaweed that becomes adrift can wash up on beaches. Kelp is a large brown seaweed that forms large underwater forests covering about 25% of the world coastlines. [65] They are among the most productive and dynamic ecosystems on Earth. [66] Some Sargassum seaweeds are planktonic (free-floating) and form floating drifts.
Seaweed is largely transported from coastal areas to the open and deep ocean, acting as a permanent storage of carbon biomass within marine sediments. [65] Ocean afforestation is a proposal for farming seaweed for carbon removal. [53] [66] After harvesting seaweed is decomposed into biogas (60% methane and 40% carbon dioxide) in an anaerobic ...
