CAPTAIN COOK, Hawaii (AP) — At the edge of an ancient lava flow where jagged black rocks meet the Pacific, small off-the-grid homes overlook the calm blue waters of Papa Bay on Hawaii's Big Island — no tourists or hotels in sight. Here, one of the islands' most abundant and vibrant coral reefs thrives just below the surface.

Yet even this remote shoreline far from the impacts of chemical sunscreen, trampling feet and industrial wastewater is showing early signs of what's expected to be a catastrophic season for coral in Hawaii.
