September Sunrise Shadows
Explanation: The defining astronomical moment for this September's equinox was on Friday, September 23, 2022 at 01:03 UTC, when the Sun crossed the celestial equator moving south in its
yearly journey through planet Earth's sky. That marked the beginning of
fall for our fair planet in the northern hemisphere and spring in the southern hemisphere, when day and night are nearly equal around the globe. Of course, if you celebrate the
astronomical change of seasons by watching a sunrise you can also look for crepuscular rays. The shadows cast by clouds can have a dramatic appearance in the twilight sky during any sunrise or sunset.
Due to perspective, the parallel shadows will seem to point back to the rising Sun
and a place due east on your horizon near the equinox date. Taken on September 15, this sunrise sea and skyscape captured crepuscular rays in the sky and watery
specular reflections from the Mediterranean coast near the village of Petacciato, Italy.

It struck me as odd that anyone on Italy's Mediterranean coast could see a sunrise like this, as it faces west. Sure enough, the picture was taken on Italy's Adriatic coast, which does face east.

Hmmm. Interesting. Yes, this was on the eastern coast of Italy, capturing a sunrise over the Adriatic. Do the locals make a distinction of "Mediterranean coast" versus "Adriatic coast"? In defense of the caption reference, it seems that most references I can find will list the Adriatic, Ionian, and Tyrrhenian seas to be parts of the Mediterranean Sea.

Indeed. When you're on the Adriatic, you are also on the Mediterranean.

This raises the question, Is the Adriatic Sea just another name for the Mediterranean Sea? Likewise is the Gulf of Mexico just a part of the Atlantic Ocean?. If you were to say to a resident of the Gulf Coast of Florida that you are on an Atlantic beach you'd be run out of town! It is the Gulf beach. This from the New World Encyclopedia referring the Gulf of Mexico geography; "The basin is roughly circular in shape and approximately 810 nautical miles (1,500 km) wide. It connects with the Atlantic Ocean through the Florida Straits between the United States and Cuba and with the Caribbean Sea via the Yucatan Channel between Mexico and Cuba. Tidal ranges are extremely small due to the narrow connection with the ocean." This clearly supposes that the Gulf is connected to, but is not part of the Atlantic Ocean!

Arms of major oceans can be called by the ocean name of the arm name. What is most common in actual usage is just a matter of convention, often local. The Gulf of Mexico is often treated as part of the Atlantic Ocean by geographers.

Remember that the Gulf of Mexico has the Gulf Stream that receives water from the mid-Atlantic and pours it into the North Atlantic, and even more, the water comes from the Antarctic circumpolar current.-
On the other hand, what about the borders on the continents?
