Photosynthesis does not occur in the winter time. Frozen trees and dead plants don't make oxygen, they are dormant.
Plankton doesn't exist in cold waters when the Earth tilts back for the winter season...to make us Oxygen in the Northern Hemisphere.
A secondary variable is nutrient availability. Although large areas of the tropical and sub-tropical oceans have abundant light, they experience relatively low primary production because they offer limited nutrients such as nitrate, phosphate and silicate. This results from large-scale ocean circulation and water column stratification. In such regions, primary production usually occurs at greater depth, although at a reduced level (because of reduced light).
