Exploring Antarctica

Until well into the 20th Century, getting to Antarctica – and returning – was a really big deal. It still is, but thanks to new technologies and operations such as the National Geographic Lindblad Expeditions, adventurous souls from around the globe are able to experience Earth’s southernmost continent and appreciate the importance of the whales, seabirds, fish and seals that live there like never before. Mission Blue founder Dr. Sylvia Earle is grateful that “the value of exploiting Antarctic wildlife as commodities is giving way to appreciating them as vital elements of systems that maintain Earth as a planet that works in our favor.” The urgency of exploring and protecting the Southern Ocean has never been greater. The following photo journal illustrates Gale Mead’s recent visit to Antarctica, South Georgia and the Falklands.…

Priority chemicals and marine biodiversity

From our new partners at the GOES Foundation (Global Oceanic Environmental Survey): by Dr. Howard Dryden, GOES Founder Nature 2010 and Nature 2011 reported that there has been a 40% drop in primary productivity in the North Atlantic since the 1950s. At the same time, oceanic pH started to decline sharply, causing seawater to acidify.  This trend may be related to an increase in industrial output and carbon dioxide emissions. However, as a marine biologist specializing in some of the largest aquarium life support systems in the world, I know that carbon dioxide is used to increase primary productivity. Woods Hole reported that an increase in carbon dioxide increased photosynthetic productivity, yet over the last 60 years there may have been a reduction by 40%.…
