Castro, Chilo\u00e9. Between September 3 and 22, 2026, professionals from the Oceanography Group at the Putem\u00fan Research Center\u2014part of the Environment Department of the Fisheries Development Institute (IFOP)\u2014conducted the “Patagonia Norte 2026” oceanographic cruise. This scientific campaign aimed to gather data on the oceanographic conditions of the southern channels and fjords.<\/p>\n

The team\u2014comprising Patricio Salas, Marcela Arriagada, Sebasti\u00e1n Sep\u00falveda, and Luis Avello from IFOP\u2019s Putem\u00fan Research Center\u2014traversed the inland waters of Chilo\u00e9 and areas within the Ays\u00e9n Region. Departing from and returning to Dalcahue, the campaign covered the Reloncav\u00ed, Comau, Quitralco, Puyuhuapi, and Ays\u00e9n fjords; the Elefantes, Moraleda, and Jacaf channels; and San Rafael Lagoon.<\/p>\n

A key highlight was the onboard analysis of dissolved oxygen using the Winkler method, performed by Sebasti\u00e1n Sep\u00falveda. Samples were collected using Niskin bottles at various stations and depths. These analyses complemented the temperature, salinity, and oxygen profiles obtained via CTDO equipment.<\/p>\n

Samples were also collected for nutrient, chlorophyll, and pH analysis. Additionally, the team carried out tasks involving the recovery of oceanographic equipment and data downloading. <\/p>\n

Data feeding the CHONOS oceanographic system<\/strong><\/p>\n

\"\"<\/a>The data obtained during these campaigns contribute to IFOP\u2019s CHONOS oceanographic information system\u2014a platform that aggregates and provides access to oceanographic data generated through field observations and modeling tools.<\/p>\n

In this way, the measurements taken during the Patagonia Norte cruise help expand and strengthen the oceanographic data record for Chilean Patagonia, providing information that can be used to understand, monitor, and analyze the environmental conditions of southern channels and fjords.<\/p>\n

\u201cPatricio Salas, the cruise leader, noted that the work carried out during this campaign allows for data collection from various perspectives of the oceanographic system. We not only measure variables such as temperature, salinity, and oxygen, but also collect water samples to determine chemical and biological characteristics, in addition to retrieving data from equipment that had been deployed for months. All of this enables us to build a more comprehensive picture of the dynamics of these ecosystems and contribute new data to the CHONOS system.\u201d<\/p>\n

The campaign is part of the project \u201cMonitoring and Modeling of the Spatial and Temporal Variability of Oceanographic Processes in Southern Channels and Fjords, 2026\u20132027.\u201d<\/strong><\/p>\n
