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

作为澳大利亚最大的植被沿海生态系统之一，海带森林提供了大量的气候缓解机会。虽然海藻碳在深海中无处不在，但海藻碳到达深汇的运输机制和数量在很大程度上仍然未知，这严重阻碍了将其纳入海洋碳预算和减缓行动。我们将利用澳大利亚范围内的海带出口、运输和腐烂的跨大陆架测量、沿海海洋环流和未来分布模型的实地数据，大大改善对海带碳转移到深海汇的估计。我们对海带固碳的全面数据驱动评估旨在揭示海藻森林现在和未来的碳汇能力
