What's Drifting Beneath Kauai's Ocean?

Residents and visitors both revel in Kauai’s lush landscape, and beneath its seascape. However, it’s underwater where things don’t look so healthy. Scientists from the U.S. Geological Survey put together a detailed picture of the physical environment of the coral reefs at Makua Beach. Understanding just what these reefs are exposed to and for how long, may help explain why some corals here have succumbed to black band disease. Footage from http://coralreefs.wr.usgs.gov/CoralDiseaseVideo.html
