The Fisheries Development Institute (IFOP) is celebrating the re-launch of CHONOS, a website that houses the oceanographic information system for southern Chile.

According to the IFOP, this new version of CHONOS maintains its public role of serving as a source of oceanographic information to government users and the general public, and features significant improvements to previously existing tools: MOSA, parti-MOSA and CLIC, to which the new ATLAS and Real-Time are added.

"The Fisheries Development Institute fulfills a public role of excellence, which is why this oceanographic monitoring website is available to all people who want to use it, it is free and easy to access. We are very proud of these advances on the website since it is the product of the work of a large team of professionals from the institute," said IFOP Executive Director Luis Parot Donoso.

Applications of the website

ATLAS is a historical data explorer based on hydrodynamic modeling of oceanographic variables such as currents, temperature, salinity (and derivatives of these as water renewal, stratification, etc.) from hourly data and monthly averages.

Real-Time allows to visualize graphs of atmospheric variables that are updated hourly (wind speed and direction, atmospheric pressure, precipitations, etc.) from the weather stations that IFOP has in the Los Lagos region, from Reloncaví to Melinka.

MOSA-ROMS: Oceanographic forecast operational model for three days in the Los Lagos region and Aysén Region. It has incorporated the visualization of the atmospheric operational forecast MOSA-WRF offering a wide spectrum of atmospheric variables for the query, such as wind speed, air temperature, humidity and precipitation.

"It is a great achievement to implement the high resolution atmospheric forecasting system MOSA-WRF, since it will allow us to have a better and more detailed knowledge and prediction of the atmospheric patterns of Northern Patagonia, which in turn will help improve oceanographic prediction," said Oliver Venegas, IFOP researcher and responsible for atmospheric modeling.
 
Parti-MOSA: The forecast of particle dispersions for the Los Lagos Region and the Aysén Region has increased the prediction of particle drifts from 3 to 10 days forward. This, according to Osvaldo Artal, researcher of the IFOP in Castro, "will allow facing in advance situations of sanitary, polluting or safety emergency and maritime rescue".

Finally, the CLIC connectivity tool now has a significantly improved resolution, us to know how particles are transported through marine currents between different areas. It is possible to choose between passive particles or to provide these particles with response to environmental conditions, so that they can simulate dispersions of various inert or biological agents (such as sea lice that affect salmon farming).

Simultaneously, IFOP is announcing the new version of CHONOS through workshops at the request of users.
