These "rocks" are really BOMBS filled with phosphoric chemicals, which burn when exposed to air. The chemicals repel water -- they drove the sea back and stranded our ship on the bottom!

Synopsis for "The First Battle of Neptunia"
A big, broken-off piece of the planet Neptune lands on Earth and forms a new continent. The land mass is inhabited, by hostile all-male Neptunians, calling themselves "The Masters", and ruled over by Solo, the Master of Masters. They in turn are served by Mechanos. Neptunian wildlife includes some dangerous Tigeapes.
Diana Prince's boss and her friends investigate the new continent, hostilities ensue, and Wonder Woman defeats the Masters. Solo escapes, and turns the table on the victors, but after another struggle, Wonder Woman defeats him again. Solo signs a peace treaty, with America, negotiated by Wonder Woman, but behind the scenes he conspires with his Masters to physically move the Earth out of its orbit, and place it in position as a new Moon of Neptune. By disguising herself as a Tigeape, Wonder Woman manages to uncover this plot. She defeats Solo and his minions for a third time.
After this, an all-female government is installed in Neptunia, to prevent future hostilities.
