You're taking your first dive in ALVIN (Fig 10.13) to witness a hot spot on the ocean floor. As you descend and arrive on site, what are your first impressions?

Explanation:

The experience is magnanimous and wonderful when witnessing the hotspot site. It was a great feeling! I could witness the red hot lava oozing out to the ocean floor from the subsurface like water from a hot-spring, and immediately, a cooling effect occurs. At that current time, the gas was coming up in the form of gas bubbles. I believed there was a mini-volcano located inside the ocean! The scene was fascinating, just like inserting a red-hot metallic-iron ball into the cool water, thereby creating a fizzing of gas and the ball's immediate cooling. It was a remarkable experience of witnessing an underwater volcano with the erupting lava and its immediate cooling to form a solid material.
