Ambitions as Deep as Their Pockets
New York Times:
A new generation of daredevils is seeking to plunge through nearly seven miles of seawater to the bottom of a rocky chasm in the western Pacific that is veiled in perpetual darkness. It is the ocean’s deepest spot. The forbidding place, known as the Challenger Deep, is so far removed from the warming rays of the sun that its temperature hovers near freezing.
Man and the last great wilderness: Human impact on the deep sea
The oceans cover 71% of our planet, with over half with a depth greater than 3000 m. Although our knowledge is still very limited, we know that the deep ocean contains a diversity of habitats and ecosystems, supports high biodiversity, and harbors important biological and mineral resources. Human activities are, however increasingly affecting deep-sea habitats, resulting in the potential for biodiversity loss and, with this, the loss of many goods and services provided by deep-sea ecosystems.
NOAA Expedition Discovers New Deep-Sea Coral Mounds
Last month, NOAA scientists used acoustic sonar to map several areas of the outer continental shelf edge off the coast of Florida. The team, on the latest mission of the research expedition “Extreme Corals 2011,” found and explored new coral mounds north of the Oculina Bank. With the help of a remotely operated vehicle—basically, an underwater robot—the team determined that the nearly 100 deep-sea coral mounds are Oculina varicosa. This is a branching stony coral species that builds mounds and acts as important habitat for economically important fish species such as grouper and snapper.
Study assesses nations’ vulnerabilities to reduced mollusk harvests from ocean acidification
Changes in ocean chemistry due to increased carbon dioxide (CO2) emissions are expected to damage shellfish populations around the world, but some nations will feel the impacts much sooner and more intensely than others, according to a study by scientists at Woods Hole Oceanographic Institution (WHOI).
