  The marine environment is one of the most important sources for microbial
biodiversity on the planet. These microbes are drivers for many biogeochemical
processes, and their enormous genetic potential is still not fully explored or
exploited. Marine metagenomics (DNA shotgun sequencing), not only offers
opportunities for studying structure and function of microbial communities, but
also identification of novel biocatalysts and bioactive compounds. However,
data analysis, management, storage, processing and interpretation are
significant challenges in marine metagenomics due to the high diversity in
samples and the size of the marine flagship projects. We provide a new
pipeline, META-pipe, for marine metagenomics analysis. It offers pre-
processing, assembly, taxonomic classification and functional analysis. To
reduce the effort to develop and deploy it, we have integrated existing
biological analysis frameworks, and compute and storage infrastructure
resources. Our current META-pipe web service provides integration with identity
provider services, distributed storage, computation on a Supercomputer, Galaxy
workflows, and interactive data visualizations. We have evaluated the
scalability and performance of the analysis pipeline. Our results demonstrate
how to develop and deploy a pipeline on distributed compute and storage
resources, and discusses important challenges related to this process.
