The Drake Passage is the narrowest constriction of the Antarctic Circumpolar Current (ACC), which connects the Atlantic, Pacific, and Southern Oceans. This region significantly influences global ocean circulation, climate patterns, and the distribution of marine species. Additionally, the strong cur...

Description
Summary:The Drake Passage is the narrowest constriction of the Antarctic Circumpolar Current (ACC), which connects the Atlantic, Pacific, and Southern Oceans. This region significantly influences global ocean circulation, climate patterns, and the distribution of marine species. Additionally, the strong currents and turbulent waters of the Drake Passage provide valuable insights into ocean mixing processes and their role in heat and greenhouse gas exchanges with the atmosphere. Dissolved nitrous oxide (N2O), and methane (CH4) were sampled during the M179/2 FjordFlux cruise, conducted aboard the German research vessel METEOR, between January 14th and February 14th, 2022. The southern Patagonian Cold Estuarine System (PCES; 54°S), including the Drake Passage (DP; 60°S), was covered. From a total of 41 stations, we present data from 8 stations covering the DP. These stations include vertical profiles of gases such as CH4, N2O and nutrients (NO3-, NO2-, PO43-). Vertical profiles of temperature and salinity were obtained ...
