The plots below were reproduced from Crawford & Peña (2021) and show oxygen on potential density anomaly surfaces. The Python code for carrying out the data processing and plotting for figures is located on GitHub.
The potential density anomaly surfaces 26.9, 26.7 and 26.5 correspond to the potential density surfaces 1026.9 kg/m3, 1026.7 kg/m3 and 1026.5 kg/m3, respectively. 1-degree and 2-degree trends were computed using least squares.
