Ongoing projects

INSTITUTO MILENIO DE OCEANOGRAFIA (end 2018 or 2023 with extension ).

 

During the last decade important understanding of the functioning of the Humboldt Current System has been achieved, but still very little is known about the vast adjoining ocean region and the mesoscale activity connecting coastal to deep sea environments. Through the Millennium Science Initiative, "Instituto Milenio de Oceanografía" seeks to establish a recognized international center dedicated to the study of globally relevant physical, biogeochemical and ecological processes in the open ocean, and to explore key under-studied deep and abyssal pelagic ecosystems associated with submarine mounts, oceanic islands, and the Atacama Trench.

UMI member Involved: Peter von Dassow.

NUCLEO MILENIO DE CONSERVACIÓN MARINA

 

The Center for Marine Conservation, launched in October 2011, is a research Nucleus of the Chilean Millennium Science Initiative (MSI). It was created to study one of the most productive marine ecosystems of the world, following four main lines of action of MS Nuclei: cutting-edge scientific and technological research, training of young researchers, collaborative networking with national and international institutions and science outreach to the society.
