The Earth Microbiome Project is a systematic attempt to characterize global microbial taxonomic and functional diversity for the benefit of the planet and humankind.

The Earth Microbiome Project (EMP) is a massively collaborative effort to characterize microbial life on this planet. We use DNA sequencing and mass spectrometry of crowd-sourced samples to understand patterns in microbial ecology across the biomes and habitats of our planet. The EMP is a comprehensive example of open science, leveraging a collaborative network of 500+ investigators, supporting pre-publication data sharing, and crowdsourcing data analysis to enable universal principles to be explored. The standardized collection, curation, and analysis are enabling a robust interpretation of ecological trends.

The Vision: Constructing the Microbial Map for Planet Earth

The EMP was founded in 2010 as a massive crowd-sourced effort to analyze microbial communities across the globe. The general premise was to examine microbial communities from their own perspective. Hence we proposed to characterize the Earth by environmental parameter space into different biomes and then explore these using samples drawn from researchers across the globe. We set out to analyze 200,000 samples from these communities using amplicon sequencing, metagenomics, and metabolomics to produce a global Gene Atlas describing protein space, environmental metabolic models for each biome, approximately 500,000 reconstructed microbial genomes, a global metabolic model, and a data-analysis portal for visualization of processed information.

Contributing Samples

We are not currently accepting new samples for the project. We have reached the capacity of what we can process at this point. We hope to have funding to be able to accept additional samples in the future. Meanwhile, if you have interesting samples, contact us, and we will take your name down and be sure to let you know when we start soliciting new samples.

Citing the EMP

If you are publishing data generated by the EMP, please feel free to include any members of the EMP team who have made a significant contribution to the work as co-authors, although this is not a requirement. The only requirements are these:

    1. Add the following text to the methods and acknowledgements: “Sample processing, sequencing, and core amplicon data analysis were performed by the Earth Microbiome Project (, and all amplicon sequence data and metadata have been made public through the EMP data portal (”
  1. The current official citation for the EMP is the 2017 meta-analysis; please cite this paper when referencing the EMP in your article:
