Poisonous run-off, rising ocean levels, increasingly acidic waters and overfishing are taking their toll on Hawaii's reefs and the marine life they support. Biologists are working hard to stem the problem but must now deal with invasive algaes that are compromising the whole reef system.

Deep Ocean Argo Floats, New Approach Yield New Insights into Ocean Acidification

Thanks to the National Oceanic & Atmospheric Administration and a joint US-Canadian research team, it is now possible for marine scientists to use satellite data from five-foot-tall Argo floats that drift with deep ocean currents to remotely monitor ocean acidity (pH) and the total carbon dioxide (CO2) content of seawater to better understand changes in ocean chemistry.

Imperiled Coral Reefs, Gone by 2050?

  Even now, three-quarters of all coral reefs around the world are threatened. By 2050 “nearly all” coral reefs will be gone unless something is done soon to stop it, according to a report released last week by the World Resources Institute. Assaulted by warming temperatures, acidifying waters, pollution, and overfishing, coral reefs are aptly described as the “rainforest of…
