How many microbes on Earth? ~5x10 30 ~1x10 23 How many stars in the observable universe?

What have we accomplished so far? Collaborators: 139 60,000 samples pledged 15,000 environmental samples being processed 20,304 completed for 16S rRNA analyses. Biomes Represented: 42 Total 16S rRNA Sequences: 1,713,425,117 Public data analysis led by EMP working group Incredibly diverse set of metadata!

EMP 10K EMP has begun an analysis of the first ~10,000 samples Recently finished the largest OTU picking run ever attempted…that we know of –13,000 samples & 1.2 billion 16S reads –Run on Amazon EC2 M2.4xlarge spot instances using StarCluster –11,000 processor consumed –560 Gb – 1.3 Tb of RAM –1.2 Tb of hard disc space Results —~10 million OTUs (97% identity) —5,594,412 non-singleton OTUs Questions/Goals —Novel Phyla/diversity —Phylogenetic overlap between and within biomes —Significant evidence for endemism, or allopatry —How much sampling is needed to sufficiently characterize an environment? —Who are the keystone species for different environments? Generalists vs. specialists? —Provide a framework for placing local datasets into a global context

Get Involved! Membership defined by participation Send us your samples –Why would the EMP help you address your hypotheses? What will your data contribute to the EMP? –If you provide MIxS-compliant metadata, we sequence your samples! $$ Help analyze data through github
