Coralline macroalgae are globally distributed rhodopyhtes that remove carbon from their immediate environment and transform it into carbonate sediments through the senescence of their calcified tissues. In this study, the calcium carbonate (CaCO) stocks in the tissue of Jania adhaerens and sediments in Tanjung Adang Shoal, Johor were quantified for a 13-month study period. The detailed maps of the geographical distribution based on the spatial and temporal variations of biomass and CaCO were also assessed. The highest amount of biomass, CaCO and organic carbon (OC) stocks in the tissues showed the highest in May 2018 and May 2019. The biomass values ranged from 65 to 143 g DW m, which contained 53-147 g CaCO m and 3-11 g OC m. These findings provided insights into the biogeochemical cycling of these inputs, which can be used to estimate the overall carbon budget of the macrophyte meadow.
柳珊瑚是全球分布的红藻，通过其钙化组织的衰老，从其周围环境中去除碳，并将其转化为碳酸盐沉积物。在这项研究中，对柔荑柳珊瑚组织中的碳酸钙（CaCO3）储量和柔荑柳珊瑚浅滩沉积物在 13 个月的研究期间进行了量化。还评估了基于生物量和 CaCO3时空变化的详细地理分布图谱。组织中生物量、CaCO3 和有机碳（OC）储量最高的是在 2018 年 5 月和 2019 年 5 月。生物量值范围为 65-143 g DW m，其中含有 53-147 g CaCO3 m 和 3-11 g OC m。这些发现深入了解了这些输入的生物地球化学循环，可用于估算大型海藻草地的整体碳预算。
