Blue carbon potential of the Great Southern Reef

作为澳大利亚最大的沿海植被生态系统之一，海带森林提供了大量缓解气候变化的机会。尽管海带碳在深海中普遍存在，但海带碳到达深海汇的运输机制和数量在很大程度上仍不清楚，这严重阻碍了将其纳入海洋碳预算和缓解行动。我们将使用澳大利亚范围内关于海藻出口的现场数据、运输和腐烂的跨陆架测量、沿海海洋环流和未来分布模型，以极大地改进对海藻向深海汇转移碳的估计。我们对海带碳汇的全面数据驱动评估旨在揭示现在和未来海藻林的碳汇能力。

As one of Australia’s largest vegetated coastal ecosystems, kelp forests provide substantial climate mitigation opportunities. Although kelp carbon is ubiquitous in the deep ocean, the mechanism of transport and amount of kelp carbon reaching deep sinks remains largely unknown, significantly hampering their inclusion in ocean carbon budgets and mitigation action. We will use Australia-wide field data on kelp export, cross-shelf measurements of transport and decay, coastal ocean circulation and future distribution models to vastly improve estimates of kelp carbon transfer to deep ocean sinks. Our comprehensive data-driven assessment of kelp carbon sequestration aims to uncover the carbon sink capacity of seaweed forests now and in the future
