Overview
the Malaspina 2010 Circumnavigation Expedition sampled the marine microbiome in tropical and sub-tropical oceans, from the surface down to bathypelagic waters (~4,000 m depth) between 2010 and 2011. This expedition has contributed to the exploration of the patterns of microbial diversity and biogeography both in the sunlit and dark oceans.
The Expedition
Named after the 18th-century explorer Alejandro Malaspina, this Spanish research expedition:
- Covered over 32,000 nautical miles across the world’s oceans
- Collected samples from the surface to 4,000 meters depth
- Visited 34 countries on all continents
- Involved over 400 scientists from 19 research institutions
Data & Resources
- 76 picoplankton metagenomes and 2672 MAGs from 11 vertical profiles from tropical/subtropical ocean available on public repositories.
- 58 metagenomes and 317 MAGs from the tropical/subtropical bathypelagic ocean.
