Gridded time series of observed oxygen concentrations along 47°N for the Labrador Sea Water layer only (between sigma-theta=27.68kg/m³ and sigma-theta=27.8 kg/m³) versus longitude. The stations are located along 47°N (±0.5°) and between 43.18°W-32°W.
The O2 values were determined on water samples either by Winkler titration or with CTD (Sensor SBE-43). Precision is 1-2%, depending on the cruise.The O2 values grids were calculated by means of objective analysis.Radius of longitude influence: 0.75°, Radius of time influence: 1.2 yr
