I was at the sea again and it occurred to me that the Mediterranean Sea is called the "ים הגדול." That was the common name for it. For example the name the Italian people gave to it was "Mare Magnum". The great sea. [That was before it became a Roman lake at which time the Romans began to refer to it as "Mare Nostrum"--"Our Sea". At any rate you see the common usage was to refer to it as the "great sea". So there is no doubt in my mind that the blessing "who made the great sea" refers to the Mediterranean.
{But I think it can also refer to the Atlantic which is the source of the Mediterranean which was just a dry desert until the Atlantic made an opening through the area of the Rock of Gibraltar.
