Data set of "The answer is blowing in the wind: seasonal hydrography and mixing of the inner sea of Tierra del Fuego, Southern Patagonia"

These data has been collected in the study publisehed on Ocean Science https://doi.org/10.5194/egusphere-2025-5692. The data is hydrography traditional CTDs and CTDs collected by elephants seals which are in ODV format. A six month at 30 m depth mooring were equipment with DO, self contained CTD NKE and a mooring line with several termistors at depth indicated in the name of the data. A meta_data.txt was also included which indicates the location of the data. This study characterizes seasonal hydrography and mixing processes in Almirantazgo Fjord, a sensitive ecosystem in southern Chilean Patagonia. Although estuarine and tidal forcing conventionally explain fjord dynamics, wind stress effects remain less understood in this high-latitude region. The study analyses a comprehensive six-month dataset including a moored time-series of temperature, salinity, and dissolved oxygen, cross-fjord CTD transects, and hydrographic profiles derived from seal-deployed sensors. Observations indicate distinct seasonality, shifting from a stratified water column in summer—defined by low-salinity surface water from glacial melt—to a mixed winter state with significantly reduced vertical stability. The analysis identifies persistent, topographically channelled up-fjord winds as a primary physical driver. By applying the Wedderburn number (Wb) and mechanical energy balance calculations, we determined that wind stress perturbs the pycnocline (Wb > 1)
