What is Blue Carbon?
Opportunity for carbon abatement
Blue carbon is the carbon captured by the world's coastal ocean ecosystems, mostly mangroves, salt marshes, seagrasses and potentially macroalgae. Historically the ocean and terrestrial forest ecosystems have been the major natural carbon sinks.
Sequestration refers to stored carbon that is unlikely to be reintroduced to the atmosphere for more than 100 years.
Recent research has identified as is assessing the natural carbon sequestration capacity in various seaweed, krill and shellfish - further exampling the scope of blue carbon of
marine environments.
Negative Carbon Emissions Projects
Untapped potential
Wetland vegetation (seagrass, mangroves, saltmarsh) occupy only two per cent of the world's seabed area, but are responsible for 50 per cent of the carbon transfer to ocean sediments.
As this carbon can remain stored for millennia, there is great interest in the concept of blue carbon — atmospheric carbon that is captured and stored (sequestered) by marine environments.
The destruction of coastal wetlands can lead to decreased storage potential of carbon and subsequent increases the threat of greenhouse gas emissions.
Ocean Carbon Sequestration
Krill’s role in Ocean Carbon Sequestration
Industrial scale projects to replace and grow the South Ocean krill stocks hold globally significant carbon sequestration potential.
Studies in 2019 and 2020 provide the first estimate of how much carbon large swarms of Antarctic krill can draw down and store through the molting process. The efficiency of this process has an important influence on our global climate. Molting krill provide a highway for ocean carbon storage (phys.org).
A study reviewed current scientific knowledge of the role of krill in processes that each year remove up to 12 billion tonnes of carbon from Earth’s atmosphere. “By eating phytoplankton and excreting carbon and nutrient-rich pellets that sink to the seafloor, Antarctic krill are an integral part of the carbon cycle and a key contributor of iron and other nutrients that fertilise the ocean,” Dr Cavan said.
