A new novel tool protects and conserves coral reefs by providing them with abundant feeding opportunities. The device, dubbed the Underwater Zooplankton Enhancement Light Array (UZELA), is an autonomous, programmable underwater light that draws in nearby zooplankton, microscopic organisms that coral feed on. It could greatly enhance local zooplankton density and increase feeding rates of both healthy and bleached coral. Providing coral with more food makes them stronger and more likely to be resilient against environmental threats like heat stress or ocean acidification.
