Harnessing nature to

fix the climate crisis and

restore the oceans


For All of Us

Seafields will develop proprietary underwater pipes to upwell nutrients that will feed the Sargassum we’ll grow in the mid-Atlantic.

Sargassum influx: nature’s gift to

helping fix the climate emergency and

restoring the oceans

Carbon sequestration needs more attention.

Stopping ongoing carbon emissions isn’t enough.

We need to scrub existing pre-industrial CO2 as well, and quickly, to avoid us reaching key climate tipping points.

Current efforts are focussed on cutting the 50 gigatons of CO2 we emit each year (GtCO2), but little thought is being put into sequestering the ~1830 GtCO2 post-industrialisation emissions that remain.

It’s difficult to visualise the scale of the problem.

One gigaton = a billion metric tons. That is the equivalent to the CO2 emissions of Germany in 1990. The 276 million cars in the US release about 1.27 gigatons of CO2 per year. The entire mass of humanity = 287 million metric tons. Sequestering more than 50 GtCO2 a year would need collaboration at a scale humanity has never seen before.

Is terrestrial carbon sequestering really nature’s best solution?

We need to plant 1.2 trillion trees to solve the problem terrestrially. The geopolitical challenge of this makes it practically unachievable, plus trees take time to grow and remove carbon from the atmosphere.

Harnessing nature to restore the oceans and fix the climate crisis, Seafields will harvest the power of the floating seaweed Sargassum to capture and store carbon at scale. Seafields is developing off-shore sustainable aqua-farms, irrigated through pipes that bring nutrient-rich waters to the surface controlling Sargassums growth, producing high value and fossil-fuel replacing products and baling and sinking the remaining carbon-rich biomass to the bottom of the ocean to lock away the carbon.

When Sargassum reaches the coast in places such as Mexico and the Caribbean in huge amounts, it has devastating effects on the coastal ecosystems (seagrass, corals, mangroves), tourism, fisheries, human health and the local economy.bit.ly/3Gb1W26#climate #CO2 #COP26 ... See MoreSee Less

Sargassum is floating seaweed that used to originate in the Sargasso sea. Due to the warming of the oceans it has spread to coastal waters causing multitudes of issues like washing up on beaches, adding more carbon to the atmosphere. By gathering, processing, baling and sinking Sargassum to the bottom of the ocean we will be storing carbon for the future and preventing the immediate release of that carbon, reducing emissions.Dr Mar Fernandez-Mendez describes what Sargassum is.#COP26 #climate #sargassum #CO2bit.ly/3pdBZc4 ...
