What are our main areas of interest?

The southeastern Pacific Ocean (SEP) is a principal interest given that it presents sharp hydrographic, biochemical and ecological gradients, from the highly productive waters of the Humboldt Current to oligotrophic waters of the Subtropical Gyre.

An important understanding has been achieved in the last decade of the structure and functioning of the Humboldt Current system. Nevertheless, little is known about the vast region of oceanic waters and of mesoscale activity that connects these contrasting environments. We at the Millennium Oceanography Institute want to focus part of our research on this area of the ocean.

What is the impact of research into the southeastern Pacific?

It is clear that the dynamics of the southeastern Pacific have a global impact for its being a region where important intermediate Antarctic are formed, for its having strong atmospheric-oceanic connections with the equatorial ocean and coastal-ocean exchanges, and for containing one of the main minimum oxygen zones (OMZ) in the world’s oceans.

The particularities of the southeastern Pacific transform it into a natural laboratory to study the functioning of the ocean and predict how ecosystems can respond to future global change. These studies represent the basis on which to plan the management-conservation of the unique ecosystems in this oceanic region.
