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-13, GAM-21, GAM-27, GAM-28) and surface and bottom water distribution (entire fjord area). The Microbiological data is provided as vertical profiles (for station GAM-21).

研究船松涅号（RV SONNE）的SO296/2航次于2023年2月3日至8日在智利阿尔米兰特蒙托湾（Golfo Almirante Montt）开展科考作业，期间采集了气体化学与微生物学数据。
项目MAPUCHE的调查目标为，通过整合生物地球化学、海洋学与古海洋学研究手段，全面解析该峡湾现今及过往的生物地球化学过程；本次采集气体化学与微生物学数据，旨在全面掌握该半封闭峡湾系统内的甲烷动力学特征及其源汇分布情况。
本数据集以文件集合形式提供气体化学与微生物学相关研究数据。其中，气体化学数据包含站位GAM-13、GAM-21、GAM-27、GAM-28的垂向剖面数据，以及覆盖整个峡湾区域的表层与底层水分布数据；微生物学数据仅包含站位GAM-21的垂向剖面数据。
