Istanbul is not on an ocean. It is located on the Bosphorus Strait, which connects the Black Sea and the Sea of Marmara. Therefore, it borders both the Black Sea and the Sea of Marmara, but not directly on an ocean.
Here's a breakdown:
- Bosphorus Strait: This narrow, natural strait is a crucial waterway that separates Europe and Asia, running through Istanbul.
- Black Sea: Located to the north of Istanbul, connected by the Bosphorus Strait.
- Sea of Marmara: Located to the south of Istanbul, also connected by the Bosphorus Strait, leading to the Aegean Sea and, ultimately, the Mediterranean Sea.
Essentially, Istanbul sits at the crossroads of these important bodies of water but is not directly situated on an ocean.
