“…Because of the relatively large mangrove catchment area of the Sungai Pulai system, any allochthonous terrestrial matter would likely be buffered and filtered from entering the river upstream and, therefore, be minimally transported downstream and into the estuary. The overlapping signatures between terrestrial OM and mangroves were distinguished by using dual isotope tracers of δ 13 C and δ 15 N, thus lowering uncertainties and increasing the robustness of the Bayesian mixing model (Greiner et al, 2016; Hidayah, Rozaimi, & Nadzir, 2019). Furthermore, the mean (± SD ) endmember δ 13 C for mangrove plants is −31.4‰ ± 0.4‰ (Table 1), calculated based on mangrove tissue signatures ranging from 29.8‰ to 33.8‰ ( n = 12).…”

“…Thus, sediment OC sequestration of macroalgae can be demonstrated if macroalgal‐derived biomass in the sediment is empirically quantified. Studies have demonstrated that macroalgal‐derived OC was simultaneously buried with seagrass‐ and mangrove‐derived OC (e.g., Chen et al, 2017; Hidayah, Rozaimi, & Nadzir, 2019; Tuntiprapas et al, 2019) and that the dominant primary producer of a coastal habitat may not necessarily contribute to the dominant OM pool (Hidayah, Rozaimi, & Nadzir, 2019; Oreska et al, 2018). Furthermore, the role of macroalgae in contributing toward the OM pool correlates with the ecological condition of the habitat.…”

Mangroves, seagrasses and macroalgae form inter-connected coastal habitats.They are involved in the direct and indirect sequestration and accumulation of blue carbon and are recognized for their role in climate change mitigation.Macroalgae, though residing within or in close proximity to these ecosystems are, however, not perceived as contributing to blue carbon storage. Such habitat connectivity among the mangrove, seagrass, and macroalgal compartments complicates a straightforward assessment of blue carbon storage. In this study, we assessed the contributions of these macrophytes as endmembers to the bulk organic carbon (OC) stocks in surficial (top 30 cm) and deep (31-100 cm) sediment layers of seagrass beds within the Sungai Pulai estuary (Malaysia).Organic carbon stocks in the seagrass sediments ranged from 14.3 to 21.4 Mg OC ha À1 (surficial depths), and 137.9 ± 23.3 (mean ± SE) Mg OC ha À1 for the deep layer. Mangrove-derived matter contributed a maximum of 65% to the bulk OC pool. The existence of downcore variability indicated that macroalgae contributed up to 16% and were higher than seagrass sources (12%). Our results suggest that macroalgal-derived and mangrove-derived organic matter are important contributors to OC sequestration in the estuary. In view of the heterogeneous OC pool that contributes to bulk OC stocks, placing importance on only one OC source may construe an incomplete profile of habitat-specific capacity for OC storage. This has wider implications for understanding OC subsidies, the effects of which are particularly relevant when one considers the impacts of coastal land use changes on blue carbon storage.

“…Studies have also shown the presence of refractive carbon compounds [129], which may be the essential organic carbon reservoir in the oceans [130]. According to some findings, organic carbon extracted from macroalgae is buried alongside organic carbon derived from seagrass [131][132][133]. Although macroalgae (especially kelp organisms) contribute significantly to the carbon cycle along the coast, most species and regions still lack accurate carbon fixation estimates [134,135].…”

Blue carbon has made significant contributions to climate change adaptation and mitigation while assisting in achieving co-benefits such as aquaculture development and coastal restoration, winning international recognition. Climate change mitigation and co-benefits from blue carbon ecosystems are highlighted in the recent Intergovernmental Panel on Climate Change Special Report on Ocean and Cryosphere in a Changing Climate. Its diverse nature has resulted in unprecedented collaboration across disciplines, with conservationists, academics, and politicians working together to achieve common goals such as climate change mitigation and adaptation, which need proper policy regulations, funding, and multi-prong and multi-dimensional strategies to deal with. An overview of blue carbon habitats such as seagrass beds, mangrove forests, and salt marshes, the critical role of blue carbon ecosystems in mitigating plastic/micro-plastic pollution, as well as the utilization of the above-mentioned blue carbon resources for biofuel production, are critically presented in this research. It also highlights the concerns about blue carbon habitats. Identifying and addressing these issues might help preserve and enhance the ocean’s ability to store carbon and combat climate change and mitigate plastic/micro-plastic pollution. Checking out their role in carbon sequestration and how they act as the major carbon sinks of the world are integral parts of this study. In light of the global frameworks for blue carbon and the inclusion of microalgae in blue carbon, blue carbon ecosystems must be protected and restored as part of carbon stock conservation efforts and the mitigation of plastic/micro-plastic pollution. When compared to the ecosystem services offered by terrestrial ecosystems, the ecosystem services provided by coastal ecosystems, such as the sequestration of carbon, the production of biofuels, and the remediation of pollution, among other things, are enormous. The primary purpose of this research is to bring awareness to the extensive range of beneficial effects that can be traced back to ecosystems found in coastal environments.

“…Initially, algal meadows were not considered a possible blue carbon contributor (Duarte et al 2005) due to their limited long-term potential for carbon sequestering (Smale et al 2018). However, recent studies have demonstrated that thanks to the source-sink mechanism (transport of a large amount of biomass of algae from euphotic coastal waters to the seabed), macroalgae can contribute signi cantly to the vertical ux of organic carbon and its sequestration in ocean sediment (Oreska et al 2918;Hidayah et al 2019).…”

Algal meadows can significantly contribute to carbon (C) capture; nevertheless, few studies on South American Pacific coast reserves are available. Evaluation of these stocks allows proposing better measures for the sustainable use of these habitats and maintaining their ecosystem services. This study aimed to estimate biomass distribution and quantify the C captured in algal meadows of Chondracanthus chamissoi on the Laguna Grande coastal lagoon (Ica-Peru). To calculate the biomass, the area occupied by each patch of algae in each sampling zone was delimited and transects perpendicular to the coast were used in randomly located plots. To calculate the biomass, randomly located plots of algae transecting perpendicular to the coast were located in each sampling zone and delimited. In the laboratory, the dry biomass and C content were measured (the latter using an elemental analyzer). Monthly variation in the distribution and area was identified. September 2021 presented the highest total biomass (50416.4 kg; 50.4 t) and C captured (13 t C) while from February to June no algal biomass was found. Significant differences were found in the biomass and C capture in the sampling zones, the months of C capture, and the interaction between these two variables. C capture decreases with warm months and more intensive algae extraction. Our results provide valuable information on the distribution of biomass and C captured over time in the study area, which will help create a more sustainable extraction process.
