Some coral reefs are keeping pace with ocean warming

Some coral communities are becoming more heat tolerant as ocean temperatures rise, offering hope for corals in a changing climate. After a series of marine heatwaves hit the Phoenix Islands Protected Area (PIPA) in the central Pacific Ocean, a new study finds the impact of heat stress on the coral communities lessened over time.

Surviving extreme heat

A team led by Anne Cohen, a scientist at Woods Hole Oceanographic Institution, received $1.75M in funding from the National Science Foundation (NSF) to study how coral reefs survive extreme heat events caused by climate change. The multidisciplinary project taps into expertise across four WHOI departments to uncover the oceanographic and biological processes that enable corals to survive marine heatwaves.

New Study Finds Distinct Microbes Living Next to Corals

Laura Weber collects a syringe sample from seawater surrounding an Orbicella faveolata coral colony in Jardines de la Reina, Cuba.

WHOI scientists distinct discover microbes living just a few centimeters from the surface of corals near the southern coast of Cuba. The discovery may yield clues about the ecological functions of microbes, and how they find and infect coral colonies.

Study Tracks Severe Bleaching Events on a Pacific Coral Reef Over Past Century

Study Tracks Severe Bleaching Events on a Pacific Coral Reef Over Past Century

As climate change causes ocean temperatures to rise, coral reefs worldwide are experiencing mass bleaching events and die-offs. For many, this is their first encounter with extreme heat. However for some reefs in the central Pacific, heatwaves caused by El Nino are a way of life. Exactly how these reefs deal with repeated episodes of extreme heat has been unclear. A new study from the Woods Hole Oceanographic Institution (WHOI), has uncovered the history of bleaching on a reef in the epicenter of El Nino, revealing how some corals have been able to return after facing extreme conditions. The study was published October 26, 2018, in the journal Communications Biology.

Galapagos Expedition Reveals Unknown Seamounts, New Species

Galapagos Expedition Reveals Unknown Seamounts, New Species

During a three-week expedition in August, an international team led by the Woods Hole Oceanographic Institution (WHOI), in partnership with the Charles Darwin Foundation for the Galápagos Islands and in close collaboration with the Galápagos National Park Directorate, conducted the first scientific expedition to map and characterize the seamounts on the Galápagos platform and the diverse marine life that these underwater mountains support.

Shifting Winds, Ocean Currents Doubled Endangered Galapagos Penguin Population

New research suggests shifts in wind currents over the past three decades, possibly due to climate change and natural variability, have nudged the Equatorial Undercurrent north. The changing current expanded the nutrient-rich, cold water farther north along the coasts of the two islands, likely bolstering algae and fish numbers in the cold pool. This allowed the penguin population to double over the past 30 years, swelling to more than 1,000 birds by 2014, according to the new study.
