We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We will also assess the risk that calcification and production of halogenic gas within the kelp forest could offset its climate mitigation potential. Project outcomes will enable management to consider kelp ecosystem services broadly and optimize our capacity to meet current emission reduction and biodiversity commitments.

我们的目标是揭示海藻森林如何为澳大利亚的碳储存、生物多样性增强和养分缓解做出贡献。我们将结合绘图和建模，以确定海带碳储量和固存潜力的本地变化，并通过海水和沉积物中的遗传追踪，验证海带碳出口到深海沉淀池。将通过营养实验和珊瑚礁调查来确定共同利益。我们还将评估海藻森林内的钙化和卤化气体的产生可能抵消其气候缓解潜力的风险。项目成果将使管理层能够广泛考虑海带生态系统服务，并优化我们的能力，以履行目前的减排和生物多样性承诺。
