This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidence of these keystones’ cellular level biogeochemical and metabolic capacity. Ultimately, this knowledge is expected to predict the resilience of ocean ecosystems and their response to change. The capacity to predict their dynamics will help provide investment clarity and increase healthy outcomes from activities involving human-ocean interactions such as recreation, food production and tourism.

该项目旨在揭示海洋隐藏的哨兵，即支撑宝贵生态系统服务的“关键微生物”，可用于监测和模拟海洋功能的变化。海洋微生物占海洋生物量的 90%，每升海水中都含有微生物。约 20,000 个不同的物种，但尚不清楚哪些物种控制着海洋健康和生产力。该项目旨在提供这些基石的细胞水平生物地球化学和代谢能力的明确证据。最终，这些知识预计将预测海洋生态系统的恢复力及其对变化的反应，从而有助于提供投资透明度并增加人类与海洋互动活动（例如娱乐、粮食生产和旅游业）的健康成果。
