IMO participates in CIMAR 21 Expedition results workshop

Monday, November 28, 2016

On 22 November, an evaluation meeting on the CIMAR 21 Expedition took place in Valparaíso, which took place between October 12 and November 5, 2015. The objective was to discuss the first results of the research, one year after the start of the expedition. The Millennium Institute of Oceanography (IMO) participated in this opportunity with researchers and students from various programs. The IMO played a fundamental role, since it provided the necessary oceanographic equipment for all the projects and contributed with three studies related to the physical, chemical, biogeochemical and biological areas.

The main focus of this cruise was the study the physical, chemical and biological conditions between the coastal zone of Chile and up to Easter Island. The idea was to compare the information obtained in a similar cruise made in 1999.

Rubén Escribano, alternate director of the Millennium Institute of Oceanography, emphasizes the importance of the CIMAR 21 Expedition for the science development "The results obtained to date highlight the importance of defining distinct ecological regions between the Chilean coast and Easter Island and that have their own fauna and key biogeochemical processes to regulate the regional climate and with global impact. Also expected to find new species for science in areas far from the coast that had not previously been studied, "said the scientist.

Meanwhile, Marcela Cornejo, young researcher IMO, participated in this expedition with her project "Plastisphere and its contribution to the GHG cycling in the South East Pacific." "What I rescued most from this expedition is the possibility doing research on issues Relevant to ecosystems and humanity and that, if there were no projects like CIMAR, it would not be possible to do so. In addition, the cruise is a unique opportunity to interact with other projects and form collaborative partnerships for scientific advancement. Researchers, technicians and students to gain experience in the field, "said the professional.

The Millennium Institute of Oceanography (IMO) also participated in CIMAR 21 with the following investigations:

-Changing hydrographic properties in the water column between Caldera and Easter Island (2015 - 1999).David Donoso, Freddy Hernández and Eduardo Navarro and Wolfgang Schneider.
