how can oceanic dissolved oxygen decline if an increase in gas temperature usually means increase in dissolved oxygen?
gpt
Basically you assume oxygen has higher solubility in water as temperature increases but, unlike solids like salt or sugar, gases are much less soluble at higher temperatures. De-gassing water to prevent corrosion or make very clear ice is done by repeatedly boiling and cooling water. So yeah : higher temperatures = less oxygen in water.
