IFOP researchers receive training in dissolved oxygen analysis
October 11th, 2024
Researchers Marcela Toro and Jurleys Vellojin received training at the Oceanographic Instrumentation Center (CIO) of the University of Concepción to perform autonomous dissolved oxygen analysis using the WINKLER method using the automatic AULOX instrument, which is manufactured by this entity.
This equipment was acquired by the Oceanography and Climate group of the Putemún Research Center – Castro, in order to improve the methods of measurement and analysis of dissolved oxygen samples. This method allows validating the accuracy of the dissolved oxygen (DO) measurement of the CTD-O, used at IFOP, this being a strategy of the institution in the advancement of the development of best practices of chemical analysis for environmental research in aquaculture sites.
This equipment will be used in oceanographic campaigns of the permanent monitoring of the IFOP, which are carried out in fjords and inland sea of Chiloé, Aysén and in the subantarctic zone, specifically in Golfo Almirante Montt. In this last place, dissolved oxygen measurements will begin, with AULOX in the campaign that will be carried out in the Austral summer of 2025. The project that will initially benefit from this acquisition is the Monitoring and Modeling of the Spatial and Temporal Variability of Oceanographic Processes in Austral Channels and Fjords project.
During the training carried out at the Oceanographic Instrumentation Center, the researchers acquired theoretical and practical knowledge of the analysis of dissolved oxygen with the WINKLER method, thanks to the excellent planning and organization of the CIO – UDEC team.
