Impact of Climate Change in the Pacific Ocean was one of the emphases of Lowphox I

Aboard the Cruise Cape Horn, 26 researchers of the Millennium Institute of Oceanography (IMO) analyzed the oxygen minimum zone and the influence of climate change in the Pacific Ocean off the coast of Iquique.

In order to investigate from different perspectives the oxygen minimum zone (OMZ) in northern Chile, to understand and assess the impact of ocean acidification and loss of oxygen in seawater as a result of climate change, national scientists sailed for 23 days in one of the five best equipped oceanographic cruises in the world.

"For the first time, we have the opportunity to work on a ship of this size and in exceptional conditions, we are proud to be part of the first group selected by CONICYT that has the ability to use time sailing on a cruise that represents a quantum leap for Chilean oceanography and take it as a great responsibility, because it allows us to show that we work globally, "said Osvaldo Ulloa, Chief Shipboard and Scientific director of the Institute.

The proposal "food webs and carbon cycling in waters of low pH and low oxygen (Lowphox I): potential impact of El Niño" was one of awarded this 2015, Ruben Escribano, alternate director of the IMO, "worked all key instruments, which is important in an expedition in which equipment that has never been tested before was used". This time tested the first Roseta completely designed and built in the country by technicians of IMO, which reached a depth of 3000 m and was used for sampling.

"We tested a relatively new boat which so far had not had a chance to make an issue of this magnitude and with the highest technology," says Dr. Escribano Department of Oceanography at the University of Concepción. Alongside this, was possible new samples of species of fish and bacteria were taken.

Executive Director of CONICYT, Christian Nicolai, said that the scientists involved in this trip "collected a lot of information that can take even up to two years to be processed in a first stage, therefore, we must also expect results to be achieved in the respective laboratories. "

With great success and an arduous task ahead, he ended the first scientific expedition developed by the National Commission for Scientific and Technological Research, CONICYT, through the Associative Research Program, PIA. It is noteworthy that with investigations by the IMO, the National Geology and Mining (Sernageomín), conducted studies to understand the transformation of the seabed associated with volcanic processes. the result of the experiments, is expected during the first half of next year for some preliminary results of the discoveries made.
