7 Stations, 48/12 months, 5 voyages Bacteria, rchaea and eukaryotes > 30 000 OTUs AMMBI represents the first methodologically standardized, continental scale, microbial ocean-observing network. The data provide a critical baseline against which to measure, and from which to predict, changes in microbial assemblages under future scenarios.

Genomics tools for estuarine status assessment 10 g sediment contains tens of millions of microbes and micro-invertebrates – thousands of different species These organisms live in intimate relationship with the environment and are sensitive indicators of its status (of many different aspects of it) Using genomics we can tell their stories Read their community structure as a fingerprint In order to be able to read this fingerprint we need to establish a baseline database Australia-wide baseline project: Microbial community structure fingerprint vs. estuarine status around 10 g of sediment that can tell the story of thousands of bacteria, phytoplankton and microinvertebrates (amongst others) living in it. these are living in an intimate relationship with the environment and their community structure is a fingerprint of the status and health of the environment. we are not yet able to read this fingerprint in detail, to a large extent because we don't have the baseline dataset to interpret it. to this end, we are working on an Australia-wide baseline of estuarine genomics – BGC – environmental status dataset.
Fragmented efforts Report Report Survey Management decision Publication Publication Management decision Report Report Publication PhD thesis a second one that visually tells the story of the fragmented efforts into estuarine observations and how these could be glued together by support for sequencing (BPA likely to provide it), for bioinformatics (BPA/CSIRO) and for BGC (missing). maybe add modelling plans there, leading to improved advice to estuarine management. Management decision = Agencies, GMOs, research groups, etc. running separate projects, collecting samples, running various analyses (chemical, physical, sometimes genomics observations). In vastly different ways to allow for direct comparison, minimizing any chance for leverage.
