eli5: Does the ocean have "seasons" like we do on land?

The deep oceans don’t experience any real temperature changes because the heat sink of all that water is simply too massive to cycle in just a few months.

What does happen is the longer day length in the summer boosts the algae and plankton populations closer to the surface, which in turn causes a boom in all the deepwater populations from the much greater food availability.

It’s no warmer in the summer, but animals will still have seasonal breeding and migration patterns to track the food availability.
