ULTRAPAC: Research Vessel Sonne in the South Pacific
17 December 2015 -28 February 2016

The Pacific Ocean covers more than one third of the earth's surface, making it the largest ocean. Its seawater is the clearest in the world and the seafloor has the lowest content of organic matter found in the deep sea. Now a team of marine scientists headed by the Max Planck Institute for Marine Microbiology crosses the South Pacific Gyre (SPG) from the west coast of Chile up to New Zealand aboard the research vessel Sonne. They want to find out how its smallest inhabitants manage to survive in this nutrient-poor water desert. Recent studies suggest that the nutrient and carbon cycles of the microbial communities are adapted to the so-called ultra-oligotrophic conditions and the great South Pacific Gyre plays a significant role for global nitrogen fixation.

Chief scientist is Timothy Ferdelman.
