Scientists from MIT and elsewhere are using submersible structures to harness the power of ocean waves and make sand accumulate in specific regions to protect islands and potentially grow new ones, reports Amy Gunia for CNN. “With each field experiment, the group says it is advancing its understanding of what materials, configurations, and construction techniques can make sand accumulate in the simplest, most cost-effective, sustainable, long-lasting and scalable way,” explains Gunia.
