This repository contains code for the paper "Progressive oxygenation of the North Atlantic subpolar gyre" published in JGR: Oceans in October 2025. Click here for the final paper.
Also check out our StoryMap for a nice graphical paper summary!
The code is split into several notebooks, listed below.
-
airsea_flux - Computing air-sea fluxes of oxygen. Fluxes are calculated with the Liang et al. (2013) parameterization, adjusting bubble components by a factor of
$\beta$ = 1.5. Includes code for producing Fig. 2a-c, Fig. 3a, and Fig. 6 (jupyter notebook) -
ECCO_Darwin_O2_mass_budget - Oxygen budget terms in ECCO-Darwin. Code for reading in data used to produce Fig. 4. Based on DIC budget code from the ECCO-Darwin github (MATLAB)
-
float_oxygen - Oxygen along float track following subpolar gyre path. Code for producing Fig. 5 (jupyter notebook)
-
isopycnal_oxygen - Calculations for oxygen changes in isopycnal layers. Includes code for producing Fig. 7 and the blue line in Fig. 6b (jupyter notebook)
