Identify the ocean located to the west of North America.

Analysis:

The map shows North America in the center. To its west, there is a large body of water labeled.

The label to the west of North America, across from Alaska and the western coast of Canada and the United States, reads 'БЕРИНГОВО МОРЕ' which translates to 'Bering Sea'. Further west, and encompassing the Bering Sea, is a larger ocean labeled 'СЕВЕРНЫЙ ЛЕДОВИТЫЙ ОКЕАН' (Arctic Ocean) to the north and 'ТИХИЙ ОКЕАН' (Pacific Ocean) to the southwest.

However, the question specifically asks for the ocean to the west of North America. The Bering Sea is a marginal sea of the Pacific Ocean, located between North America and Asia. The Pacific Ocean is the large ocean body to the west of the continent.

Considering the scope of the question asking for 'the ocean', and the prominent labeling of the large body of water west of the continent, the most appropriate answer is the Pacific Ocean, which includes the Bering Sea as a part of it.

The map shows 'БЕРИНГОВО МОРЕ' (Bering Sea) directly to the west of Alaska and then a larger body of water extending southwards labeled 'МОPE' which is part of the Pacific Ocean.

Re-examining the map, the body of water directly to the west of North America, and south of the Bering Sea, is labeled as part of the Pacific Ocean.

The label 'БЕРИНГОВО МОРЕ' is directly to the west of the northwestern part of North America (Alaska).

The label 'ТИХИЙ ОКЕАН' is not explicitly written on the western side of North America in this cropped view, but the Bering Sea is a part of the Pacific Ocean.

However, there is a clear label 'БЕРИНГОВО МОРЕ' to the west of Alaska.

Let's look at the larger context. The ocean west of North America is the Pacific Ocean. The Bering Sea is a part of it. Given the direct labeling, 'Bering Sea' is a specific and accurate answer for the region immediately west of northwestern North America.

If we consider the entire western coastline, it borders the Pacific Ocean.

Looking closely at the labels, to the west of Alaska and the Aleutian Islands, 'БЕРИНГОВО МОРЕ' is clearly marked.

Answer: Bering Sea
