Researchers from Ecuador, Colombia, Peru and Chile participated in a Workshop about Optimal Multiparametric Analysis method Implementation and application
January 4th, 2021
It will make it possible to accurately identify water masses present off South American coast.
Between December 21rst and 22nd the virtual course ” Optimal Multiparametric Analysis Implementation and application(OMP) method within the framework of the Researchers Exchange program” was held.
It was organized by Oceanography and Plankton Section from IFOP Oceanography and Environment Department and financed by a Performance Agreement between IFOP and CORFO in 2020. It was developed within the framework of researchers of the Coordinating Committee of Regional Cruises exchange program ( CC CR ERFEN) of South Pacific Permanent Commission (CPPS).
Researchers and Technicians from Ecuador, Colombia, Peru and Chile participated from:
Valparaíso Oceanography and Environment Department
Puerto Montt Environment Department
Ecuador Oceanographic and Antarctic Navy Institute (INOCAR)
Colombia General Maritime Directorate (DIMAR)
Peru Sea Institute (IMARPE)
Cristina Carrasco, professor, Oceanographer, Master of cience and Universidad de Concepción PhD eligible,.
The workshop was aimed at researchers and technicians working on the description of bodies of water in the Eastern South Pacific. The method of calculating water masses, which applies the optimal multiparametric analysis (OMP), is a tool that allows to better determine the participation percentages of water masses using chemical variables, such as oxygen and nutrients, together with those already traditional variables temperature and salinity, which are used in the traditional calculation method through the mixing triangle.
In the course’s two days the following topics and / or activities were developed:
– Optimal multiparametric analysis method (OMP) rationale and authors of
– OMP use Considerations, criteria and information
– OMP script delivery to the participants and a PDF course presentation.
– Matlab format script description that allows OMP calculation
– Program operation example
– Program Application Exercise with own data by country
This tool implementation will allow incorporating the analysis of water masses obtained with OMP method in reports or publications made by different working groups that participated in the course, as well as in reports of the annual regional cruises within the framework of the South Pacific Permanent Commission.
