What are coral reefs? Coral can be found in tropical ocean waters around the world. But how much do you know about reefs and the tiny animals—polyps—that build them? Learn all about coral and why warming waters threaten the future of the reef ecosystem.
sunscreens & corals
toxicologist on sunscreen
Retired scientist and toxicologist who spent 38 years formulating chemical sunscreens, now works to educate about the dangers of sunscreen ingredients like oxybenzone and octinoxate to people and the environment. We had the pleasure of speaking with Joe Dinardo while on a water testing mission at Hanauma Bay on Oahu, Hawai’i, November 2017
reefs at risk
Set on the beautiful beaches of Hawaii, “Reefs at Risk” explores the harmful effects sunscreen chemicals have on coral reefs and marine life. To protect this fragile ecosystem, Hawaii strives to ban a commonly used UV chemical oxybenzone and hopes other states & nations will follow. Includes Lisa Bishop (Friends of Hanauma Bay), Craig Downs (PhD & Executive Director Haereticus Labs), Honour Booth (UH Manoa ecotoxicology student), Jeff Bagshaw (DLNR).
eco-tourism & sunscreen
“Coral reefs are a $10 billion resource for our local economy as well as the home of all the nearshore marine life that’s so important to local fishermen and all of us that grew up here.” ~ Rep. Chris Lee, Chair, 2017 Hawaii State House Energy and Environmental Protection Committee
sunscreen & corals
A new study found a common ingredient in sunscreen, oxybenzone, is threatening coral reef conservation.
TED-Ed: Mary Poffenroth explains how sunscreens work and compares different application methods, SPFs, and active ingredients to help you make the best choice.

corals in hawai’i
Gates Lab, Kaneohe Bay: Scientists and volunteers collect coral sperm and eggs on a moonless summer night to selectively breed to develop “super corals” that can withstand warmer waters and other effects of climate change.
Hawai'i Coral bleaching
After the worst coral bleaching event ever recorded in Hawaii, the Hawaii Institute of Marine Biology at the University of Hawaii at Manoa is diligently monitoring and testing affected coral reefs in Kaneohe Bay.
DOER Marine with Canon USA capture first color HD video of deep ocean bioluminescence in Hawaiian Bamboo Corals that shows behaviors heretofore only conveyed by written and oral histories. [Dr. Sylvia Earle]
First ever footage of coral bleaching, taken by scientists in a laboratory at Queensland University of Technology in Brisbane, Australia, captures a coral ejecting its resident population of algae. The behavior helps corals survive warmer water in the short term, but extended periods of bleaching can be lethal to corals and the ecosystems they support.
Human efforts to save the coral reefs. Breeding super corals. They could breed a monster coral that could take over the reefs. It’s daring science. The stakes are huge. Time is running out. Can we save the coral reefs? Emma Johnston, professor of marine ecology at University of New South Wales, board of Great Barrier Reef Marine Park Authority, explores the topic. With Dr. Ruth Gates and Madeleine van Oppen.
