The Mother Colony of the West Indies
This is the North Atlantic Ocean.
It can be judged by its surrounding, as it is located near the North Pole, we can deduce that it is an ocean located at the north, which could either be north Atlantic or North Pacific.
We can then use the continential plate to help us determine, which is the North America plate.
Therefore this is the North Atlantic Ocean.
Hope it helps!
You would go upstream as in north if you would go down stream it would be south
