"One of the planetโs most vital #CarbonSinks i.e. SOUTHERN OCEAN (SO) (absorbs ~40% of C) is revealing its secrets as tiny organisms in the SO play an outsized role in moderating Earthโs #climate."
Details from the recent research are discussed in a๐งตโฌ๏ธ 1/8
"Based on 107 independent observations of the seasonal cycle from 63 #biogeochemical profiling floats, new study conducted by scientists from #NOAA & University of Hawai'i provide the basin-scale estimate of distinct biogenic #CarbonPool production at Southern Ocean." 2/8
Researchers find "significant meridional variability with enhanced #ParticulateOrganicCarbon production in the subantarctic & polar Antarctic sectors & enhanced #DissolvedOrganicCarbon production in the subtropical & sea-ice-dominated sectors." 3/8
"#ParticulateInorganicCarbon production peaks between 47ยฐS and 57ยฐS near the โgreat calcite belt.โ Relative to an abiotic Southern Ocean (SO), organic C production enhances CO2 uptake by 2.80 ยฑ 0.28 Pg C yโ1, while PIC production reduces CO2 uptake by 0.27 ยฑ 0.21 Pg C yโ1." 4/8
"Without organic C production, the SO would be a CO2 source to the atm. The findings of this study emphasize the importance of #DOC & #PIC production, in addition to the well-recognized role of #POC production, in shaping the influence of C export on airโsea CO2 exchange." 5/8
IN SIMPLE WORDS โฌ๏ธ
๐ "Researchers discovered that if the amount of #carbon produced by tiny organisms in Southern Ocean decreased by 30%, the Southern Ocean would release carbon dioxide instead of #absorbing it, which could worsen the #GreenhouseEffect on our planet." 6/8

@4401earth raised $37M Series A funding for its mineralisation tech which aims to eliminate CO2 permanently & at scale. The funding will enable 44.01 to continue to refine its tech, develop commercial-scale projects & expand its deployment globally.
@Climeworks has signed a multi-year contract with Zรผrcher Kantonalbank. The agreement aims to remove around 1,750 tons of COโ that complements the Swiss bank's net-zero strategy, which continues to focus on emissions reductions.

@1PointFive_ has entered into an agreement with Microsoft to sell 500,000 metric tons of CDR credits over 6 years to support Microsoftโs CDR strategy. The agreement is the largest single purchase of CDR credits enabled by Direct Air Capture to date.
Sydney startup Fugu Carbon has secured funding within the range of $1 million to $1.7 million for its solid direct-air carbon capture solution. It will allow Fugu to further develop and scale its team and operations.

@heirloomcarbon unveiled plans to deploy 2 facilities in Shreveport, Louisiana, capable of removing 320KtCO2 per year at scale. The first facility will remove 17KtCO2/yr, with the second scaling up to remove 100KtCO2/yr by 2026 & 2027, respectively.
Denmark is investing โฌ1.35B into biochar carbon removal and plans to subsidize biochar carbon removal by up to โฌ300/t. Additionally, Denmark has become the first country to introduce a โฌ100/t CO2 tax in agriculture.
