The BBC reports on research pointing to the importance of seagrasses to protecting coral reefs against the impacts of ocean acidification, caused by carbon dioxide from fossil fuel emissions dissolving in seawater, causing unprecedented increases in the ocean’s acidity.
We’ve described ocean acidification as potentially the “the gravest and most immediate planetary threat yet,” and as more and more research results become public, it appears that this threat is, indeed, every bit as potent as we had feared.Yet it has been a painfully slow process for ocean acidification to gain traction in the media and is still far from being a “mainstream” issue. So when the San Francisco Chronicle recently called for action to deal with the issue, we took notice. [Read more…]
This infographic from MastersDegree.net lays it out there for all to see: Our oceans are getting more and more polluted, and most of the pollution originates from land, like plastics. These pollutants have a wide range of impacts on marine life, including getting caught up in the food chain, even at a microbial level. Scary stuff. Please share!
We’ve barely explored the world’s oceans, but when it comes to marine life living in the harsh conditions at the poles where few scientists and explorers can spend time, we are constantly being surprised by what we’re discovering. The Greenland shark — the largest shark in the dogfish family — is no exception. It’s slow — really slow — so scientists asked the logical question: “If it’s so slow, how does it catch prey?” The BBC reports on a recent study. [Read more…]
Only three men have ever reached the ocean’s deepest point. Capt. Don Walsh and the late Jacques Piccard in 1960 and earlier this year, James Cameron. On June 14th, 2012, National Geographic bestowed its highest honor, the Hubbard Medal, posthumously to Jacques Piccard for his record-breaking dive to the Mariana Trench with Don Walsh in the bathyscaphe Trieste to a depth of nearly seven miles. Many of his efforts greatly contributed to the fields of oceanography and conservation.
Piccard comes from a family of explorers. His father, Auguste, was a physicist and the first man to take a balloon into the stratosphere. In 1999, Jacques Piccard’s son, Bertrand Piccard, together with Brian Jones, completed the first ever nonstop circumnavigation of the globe in a balloon.
Presenting the Piccard family with the Medal was Don Walsh, who received the Hubbard Medal in 2010 and James Cameron, the last and only other man to reach this depth.
