Here's why:
* Latitude: 77° N is very high, placing it in the Arctic region.
* Longitude: 45° W is in the western hemisphere, putting it in the Atlantic Ocean.
* Combining both: This combination points to the northern part of the Atlantic Ocean, specifically the region of Greenland and Baffin Bay.
It's important to note that this specific location is within the Baffin Bay region, which is a large body of water located between Greenland and Canada.
