Distribution of surface Apparent Oxygen Utilization in the biological context of the Southern Ocean in 2011.

<p>The AOU values indicate that the most oxygenated surface waters (i.e. the lowest AOU) within the PFZ and north to the SAF were related to the higher chlorophyll-a concentrations. No relation was observed in 2010.</p

Distribution of surface oxygen in the physical context of the Southern Ocean.

<p>a) In 2010, the more oxygenated waters were mainly located south to the Fawn Through Current (FTC), also called the surface expression of the Polar Front and here symbolized by the 0.5°C isotherm. b) In 2011, the surface waters North to the Subantarctic Front (SAF) were low oxygenated compared to surface waters located South to the Polar Front. Within the Polar Frontal Zone (PFZ), no clear pattern appears in the distribution of dissolved oxygen regarding to the main physical structures.</p

Temporal drift of the seal oxygen sensors.

<p>Deep oxygen values (> 400 m) as a function of time showing a constant decrease in oxygen value that start after approximately 30 days at sea. Red lines represent fitting curves.</p

Relationship between the AOU values along the seal tracks and the mean concentration of Chl-a extracted under each location recorded in 2011.

<p>The higher the concentration in Chl-a, the lower the values of AOU. The black line represents the significant linear regression: <i>y</i> = −6.4<i>x</i> + 23.7, p < 0.001.</p

Difference in dissolved oxygen concentration along the seal tracks regarding the position of the main oceanic fronts a) in 2010 b) in 2011.

<p>The fronts were defined by the sea surface temperature and the literature.</p

Location of oxygen profiles recorded by Kerguelen elephant seals and the ship survey Keops2.

<p>The seal profiles were obtained during the post-breeding foraging trip of 5 females. The individual #1 was equipped in October 2010. The 4 other females (#2 to #5) were equipped in October 2011. Blue dots correspond to the Keops2 stations (Keops St). The Keops survey was conducted in October and November 2011. Isobaths are illustrated in light gray.</p

Zoomed location of seal and Keops profiles that have been compared.

<p>The selected profiles are in red (large dots = Keops; small dots = Seals). The letters a,b & c correspond to the profiles presented in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132681#pone.0132681.g003" target="_blank">Fig 3</a>.</p

Temperature-Salinity diagram from seal data.

<p>Points are coloured by oxygen values. SAZ = Sub-Antarctic Zone, PFZ = Polar Frontal Zone, AZ = Antarctic Zone.</p

Comparison between the seal (red lines) and the nearest Keops Oxygen-Depth profiles (black lines).

<p>A gap between the profiles appears in the Oceanic Mixed Layer (OML). The letters a,b & c correspond to the profiles located in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132681#pone.0132681.g002" target="_blank">Fig 2</a>.</p
