Gas-chemical and microbiological data of RV SONNE during cruise 296/2 in the Golfo Almirante Montt (Chile)

Gas-chemical and microbiological data were collected during RV SONNE cruise SO296/2, which took place in the Golfo Almirante Montt (Chile) between February 3rd and 8th 2023. The aim of the investigations of the project MAPUCHE was to gain a comprehensive understanding of recent and past biogeochemical processes in the fjord by combining biogeochemical, oceanographic, and paleo-oceanographic investigations. The gas-chemical and microbiological data were collected in order to obtain an overview of the methane dynamics and the methane sources and sinks in the semi-enclosed fjord system. The data are provided as a collection of files for the gas-chemical and microbiological studies. Gas-chemical data are given as vertical profiles (for station GAM-21) and surface and bottom water distribution (entire fjord area). The Microbiological data is provided as vertical profiles (for station GAM-21).
