52 degrees north, 0 degrees is located in the North Sea, specifically off the coast of England, near the Thames Estuary.

Here's why:

* Latitude: 52 degrees north is a line of latitude that runs through parts of England, France, Belgium, the Netherlands, and Germany.

* Longitude: 0 degrees is the prime meridian, which runs through Greenwich, England.

Therefore, the point where these two lines intersect is in the North Sea, close to the English coast.
