Imagine this breakthrough: the ocean off South Carolina being explored by drones that act like flying fish -- zipping over the sea surface and diving below. They're considered drone "gliders," flying to specific programmed spots in the ocean before going under to take measurements before resurfacing to fly back. "Just imagine, in a few years, we will have swarms of these things," said Christian de Moustier, IEEE Oceanic Engineering Society president. With that and other emerging technology, "we will have an amazing amount of data, ways to monitor the changes in the ocean and see where the changes are going," he said. And there will be torpedo-like, remotely operated submarines that will record and give forecasters temperatures in the water under a storm's core -- a critical, previously missing piece of data that already helped forecast Hurricane Florence's strength and track.
