The biological pump transports organic matter, created by phytoplankton productivity in the
well-lit surface ocean, to the ocean's dark interior, where it is consumed by animals and …

The conservation, restoration, and improved management of terrestrial forests significantly
contributes to mitigate climate change and its impacts, as well as providing numerous co …

The coastal ocean represents an important global carbon sink and is a focus for
interventions to mitigate climate change and meet the Paris Agreement targets while …

The ocean contains about 40 times more carbon than the atmosphere, storing 38,000 Pg C
as dissolved inorganic carbon (DIC) versus 900 Pg C as carbon dioxide (CO2) in the …

Multiple processes transport carbon into the deep ocean as part of the biological carbon
pump, leading to long-term carbon sequestration. However, our ability to predict future …

There have been discussions of scaling up offshore seaweed cultivation and sinking it
exclusively for carbon sequestration ('ocean afforestation') and thereby help mitigate climate …

Sinking vast amounts of seaweed in the deep ocean is currently being proposed as a
promising ocean carbon dioxide removal strategy as well as a natural-based solution to …

The carbon sequestration potential of open-ocean pelagic ecosystems is vastly under-
reported compared to coastal vegetation 'blue carbon'systems. Here we show that just a …

Recently, Gallagher et al. suggested that seaweed ecosystems are net heterotrophic carbon
sources due to CO2 released from the consumption of external subsidies. Here we outline …

Kelp forests may contribute substantially to ocean carbon sequestration, mainly through
transporting kelp carbon away from the coast and into the deep sea. However, it is not clear …
