Summary: Although unseen, microbes underpin the health of our ocean ecosystems. They represent 50-90% of total ocean biomass, regulate ocean chemistry and influence climate. However, we know very little about their composition and function in Australian waters. Our research will close this knowledge-gap by employing; (i) state-of-the-art genomic tools to identify the microbes inhabiting key Australian marine waters and (ii) a suite of innovative physiological measurements to determine how these microbes alter the chemistry of seawater. During a time that climate change is altering Australian marine ecosystems, this data will allow us to define the essential ecosystem services provided by marine microbes and how these may change in the future.
