For Yous Data - Are Nosotros Losing I Of Our Biggest Co2 Sinks?

In a novel written report spanning coastal areas of the Northern Hemisphere, a coordinated researcher network led past times MSc Emilia Röhr, Assoc. Prof. Christoffer Boström from Åbo Akademi University too Prof. Marianne Holmer from University of Southern Kingdom of Denmark explored the magnitude of organic carbon stocks stored too sequestered past times eelgrass (Zostera marina) meadows--the nigh abundant seagrass species inwards temperate waters.

"We discovered that eelgrass organic carbon stocks were comparable to organic carbon stocks of tropical seagrass species, also equally mangroves, saltmarshes too terrestrial ecosystems", Emilia Röhr says.

On average, eelgrass meadows stored 27.2 tons of organic carbon per hectare, although the variation betwixt the regions was considerable (from iii to 265 tons per hectare). Hotspots for carbon sequestration were identified peculiarly inwards the Kattegat-Skagerrak region, too southern parts of the Baltic Sea where the organic carbon stocks were over 8 times higher, than inwards the Archipelago Sea of Finland.

The high carbon storage capacity of eelgrass meadows urges for protection too restoration of this unique ecosystem. Especially inwards the areas alongside the highest carbon stock capacity, they deserve recognition equally business office of global carbon marketing programmes.

"Terrestrial forests are good known for their capacity to shop carbon (green carbon), piece the so-called bluish carbon stored too sequestered past times coastal vegetated ecosystems, such equally mangroves, saltmarshes, macroalgae too seagrasses, get got received much less attention", says Röhr.

"Although these encompass solely 0.5 % of the seafloor, their carbon storage capacity accounts for to a greater extent than than 55 % of the carbon stored past times photosynthetic activeness on Earth."

In the marine systems, the bluish carbon species solitary draw organisation human relationship for upwards to 33 % of the sum oceanic CO2 uptake. In contrast to terrestrial soils, which commonly shop carbon upwards to decades, the carbon stored inwards bluish carbon ecosystems may persist for timescales of millennia or longer too thus, contribute significantly to climate modify mitigation too alleviation of the ascension atmospheric carbon dioxide concentrations. Despite the importance of these ecosystems, to date, none of them are included inwards the global carbon trading programmes. Alarmingly, inwards the past times l years, at to the lowest degree 1/3rd of the distribution expanse of coastal vegetated ecosystems has been lost.

The findings are published inwards Global Biogeochemical Cycles.
