We analyzed stored carbon in the Above Ground Biomass (AGB) and Below Ground Biomass (BGB) of three seagrass species in Koswari, Kariyachalli and Vilanguchalli during March, 2014 at Gulf of Mannar. Soil Organic Carbon (SOC) was also monitored simultaneously to evaluate the amount of stored carbon in the underlying soil of the intertidal mud flat in the study area. In the selected quadrate, the order of abundance of the seagrass species was Cymodocea serrulata > Thalassia hemprichii > Halophila ovalis. Pronounced variation was observed between AGB and BGB in all the three species. The ratio of AGB and BGB ranged from 1:1.25-1:1.30. The Above Ground Carbon (AGC) and Below Ground Carbon (BGC) also exhibited significant variation with highest value in Cymodocea serrulata followed by Thalassia hemprichii and Halophila ovalis.

Seagrass meadows have one of the highest carbon sequestration and storage capacities than any other ecosystems. Carbon that is stored in the ecosystem is accumulated in the deposited sediment as well as in the living, above and below ground biomass, with a different rate of carbon sequestration and storage between the species. The objective of this research was to investigate carbon storage in the living plants and in the sediment among species of different size in tropical waters. The samples were collected from Phuket province, Thailand, in the high density monospecific patches of different size species (Enhalus acoroides as a big, Thalassia hemprhicii as a medium and Halophila ovalis as a small size species). Total carbon and carbon stored in above and below ground, was significantly different between the species (p<0.05), with the highest values in below ground parts of E. acoroides and T. hemprichii 238.10±85.07 and 134±21.55 g Dw m-2 , respectively. Average organic carbon in the sediment was significantly different (p<0.05) as well, with E. acoroides having highest organic carbon content in the deeper layers of the sediment 1.14±0.25 % C org , while the other two species had higher organic carbon in the top and medium layers of sediment. The results of this preliminary research propose that big size species have higher carbon content than smaller species, which reflects in higher sequestration rates of carbon from the ocean, thus reducing the ocean carbon budget. Moreover, it provides necessary information on size of the species which is the key for the future carbon storage studies in the region.

Vegetated habitats like mangroves, seagrasses and saltmarshes capture and store carbon and act as carbon sinks. The carbon captured and stored in these habitats, especially in the belowground sediments, is called blue carbon. We report the blue carbon storage potential of seagrass habitats from the lagoons of Agathi, Bangaram, Kavaratti, Kalpitti, Thinnakara and Parli Islands of the U.T. of Lakshadweep. Sediment core samples were collected in triplicate from 30 cm deep from six stations located in the lagoons and estimated the organic carbon content in the sediment samples. The mean C org ranged from 0.1863 (Bangaram) to 0.3453% (Thinnakara); while the dry bulk density was 0.9115 (Kalpitti) to 1.1174 g/cm 3 (Kavarathi). Of the six Islands studied for blue carbon storage, the Thinnakara lagoon registered the highest level of 0.9795 mgC/ha and the Bangarum lagoon showed the lowest rate of 0.3796 mgC/ ha. Very low organic carbon stock in these lagoons indicated an urgent need for restoring and reviving the seagrass meadows, which are shrinking rapidly.
Currently, the function of seagrass community as carbon storage has been discussed in line with “blue carbon” function of that seagrass has. Seagrass bed are a very valuable coastal ecosystem, however, seagrass bed is threatened if compared to other coastal ecosystems, such as mangroves and coral reefs. The threatened seagrass experienced also contributes to its capacity in absorbing CO2 emission from greenhouse gasses such as CO2 emission. Temporal estimation shows that CO emission will increase in the coming decade. On the other side, efforts to decrease climate change can be influenced by the existence of seagrass. Informations about existence of seagrass as carbon storage are still very rare or limited. This study was aimed to estimate carbon storage on seagrass community in Marine Nature Tourism Park of Kotania Bay Area, Western Seram, Maluku Province. The quadrat transect method of 0.25 m2 for each plot was used to collect seagrass existence. The content of carbon in the sample of dry biomass of seagrass was analyzed in the laboratory using Walkley & Black method. The results showed that total carbon stored was higher in both Osi and Burung Islands of Kotania Bay than other studied areas (Buntal and Tatumbu Islands, Marsegu Island, Barnusang Peninsula, Loupessy and Tamanjaya Village). The average carbon stored in Kotania Bay waters was 2.385 mg C ha-1, whereas the total of carbon stored was 2054.4967 mg C

Various human activities emit carbon dioxide which drives global warming and climate change. Seagrass ecosystems can absorb and store enormous quantities of carbon, hence reducing carbon emissions. This research aimed to assess the diversity, vegetation cover, carbon stock and associated biota of seagrass beds in Central Tapanuli District, North Sumatra, Indonesia. Purposive sampling method was employed with data collection used the line transect quadrant method. Carbon stock was measured using the loss of ignition method. There were four species of seagrass in the studied area, namely Enhalus acoroides (L.f.) Royle, Thalassia hemprichii (Ehrenb. ex Solms) Asch., Cymodocea rotundata Asch. & Schweinf. and Halodule uninervis (Forssk.) Boiss. with a density ranging from 23-164 stands/m 2. Seagrass cover ranged from 3.87%-34.37%. Associated biota (fish and crustaceans) at each observation station were Siganus

Small islands are particularly rich with coral reefs and seagrass ecosystems and coastal plants. Seagrass is one of the coastal ecosystems of blue carbon, which is capable of storing utilize and store CO2 in the form of organic carbon in biomass and sediment. The purpose of this study to get the carbon stock of seagrass and its role in climate change. The survey method with sampling purposive sampling representing all research sites and analyzed the amount of carbon contained in biomass and sediment. The result showed that there were eight species of seagrass found, and the highest carbon stock on the type Enhalus acoroides at Kapoposang island was 1.64 MgC / ha. The average value of the total biomass of carbon stock in the island's largest seagrass Bauluang island was 1.89 ± 0.92 Mg C / ha with the largest at the ground below 77% of total carbon biomass. Carbon stock in sediments of seagrass ecosystems average of 531.87 ± 74.08 Mg C / ha up to a depth of 50 cm. The role of s...

Seagrass meadows are an important component of coastal ecosystems globally, and they capture and store organic carbon in living biomass and sediments. Geographical estimates of blue carbon in seagrass habitats are regionally biased, with limited information from the Indo-Pacific region, including Indonesia. Seagrass extent in Indonesia is declining rapidly, and it has been suggested that marine protected areas (MPAs) are an important instrument to support protection of seagrass ecosystems and their services. Thus, this study is aimed at quantifying and comparing sedimentary carbon stocks and sources of organic carbon from seagrass meadows located in undisturbed areas outside MPA, disturbed areas outside MPA, and within MPA in three small islands in Indonesia. The sediment carbon stocks from this study ranged from 19.81 to 117.49 Mg C ha−1, with the highest stock measured inside MPA (77.15 ± 1.38 Mg C ha−1), followed by undisturbed outside MPA (36.08 Mg C ha−1), and the lowest stock ...
