Jamaican researchers are testing underwater speakers that play healthy reef sounds to attract fish to bleached corals, following a similar Great Barrier Reef study that boosted fish on sound-equipped artificial reefs; the effort also involves 3D-printed artificial reefs and lab-grown coral with the Alligator Head Foundation, but it's too early to know if Jamaica will see recovery, and volunteers can support via the foundation.
A new study has found that the sounds emanating from coral reefs change rapidly as the Moon rises and sets, indicating shifts in ecosystem activity. Researchers monitored three reefs off the west coast of Hawaii and discovered that fish sounds increase during moonlight hours while invertebrate sounds decrease. This discovery suggests that the rising and setting of the Moon triggers regular shifts in coral reef ecosystem interactions, which could aid in conservation efforts and tracking long-term ecosystem activity in remote locations.
The US Coast Guard reported hearing sounds and banging noises from the search area for the Titanic submersible. The search is being conducted to investigate the wreckage and debris field of the Titanic, which sank in 1912. The Coast Guard is using advanced technology to locate and explore the area, and hopes to gain new insights into the disaster.
