As the crew and science team watched from the M/Y Golden Shadow, a bigger, brighter moon filled the night sky rising above the island of Vanuabalavu on June 23, 2013. When the moon is closest to Earth, called perigee, it
The Golden Shadow arrived in Papeete, French Polynesia back in July 2012 and for the past eight months it has been our home, but we said goodbye to Papeete last week as we started our final research expedition in the
One of our survey methods that we do while diving at each site is photo transecting. Photo transects involve taking evenly measured photos of the reef bottom. This not only gives us a permanent record of the reef condition, but
It’s been two weeks since the Gambier portion of the Global Reef Expedition to French Polynesia ended. In less than two weeks, our science team will be heading back to French Polynesia to conduct research in Rangiroa. In the meantime,
Mangareva contains more diverse coral habitats than anything we have seen to date. Parts of the outside rim of the atoll are emergent. The cross sectional profile starts with a classic reef flat, 10 m wide in places and often
Cauliflower coral, in the genus Pocillopora, are among the most widely distributed and most abundant corals found on the fore reef. These branching corals are covered with small bumps (called verrucae), which contain corallites and help in the identification of
Navigation hazards are many in Hao Atoll, due to a myriad of submerged patch reefs that rise to the surface from the 60 m deep lagoon floor. These reefs are distributed in a seemingly random pattern. Some are circular and
“Ocean acidification” is a term you may have heard in relation to coral reefs. As carbon dioxide increases in the air, the amount in the ocean goes up as well. The increased carbon dioxide makes the ocean water more acidic,
Mention coral reefs and most people think of sweeping landscapes of corals, sponges, and fish. While those do exist in Hao Atoll, researchers are also seeing the reef through different lenses. Satellite Imagery for Reef Habitats and Geomorphology of Coral
Research dives can be distilled down to lists of what is seen and what is not seen. Surveying the reef means figuring out what is there and what is missing. For the last few days, the science team has been
