Time series of temperature, salinity, oxygen, and Ekman derived variables in period 2016-2014, Patagonian Fjords

A mooring system was deployed at GM (43°57′ S, 73°40′ W), at an average depth of ~170 m, and equipped with DO and conductivity–temperature sensors positioned between 170 and 174 m. This site was selected to monitor the variability of deep-oxygen conditions and ventilation processes in the northern Patagonian fjord system. The datasets were subsequently averaged to a daily resolution for reducing high-frequency variability (e.g., semidiurnal tides) and ensuring consistency with the temporal scales of the synoptic, intraseasonal, seasonal, and interannual time-scale analyses. DO was recorded using a MiniDOT optical oxygen logger (PME; https://www.pme.com/products/minidot), whereas temperature and conductivity were obtained using an RBR dual-channel logger (RBR Ltd.; https://rbr-global.com/products/standard-loggers/rbrvirtuoso).
