The Big Fish That Got Away… (It Was Let Go)
In Karimunjawa National Park, a marine park in Indonesia, fishermen caught something besides anchovies and small bait fish in their net: a juvenile whale shark. The young shark was already four meters (more than 13 feet) in length. The fishermen immediately notified staff members from the Karimunjawa National Park Authority and the Wildlife Conservation Society using a new text message system that was initially established for reporting fishing violations. The whale shark was successfully released soon after officials arrived.

Nature’s Glowing Slime: Scientists Peek into Hidden Sea Worm’s Light
Parchment tube worms produce slimy bioluminescent mucus. This glowing mucus hasn’t been studied by scientists in over 50 years, but now researchers are getting closer to determining how this marine worm produces light. It is unique because most bioluminescence is produced as short flashes of light in the green spectrum, but this worm produces a long-lasting glow of blue light. Watch the following video with researcher Dr. Dimitri Deheyn to learn more:

New generation of micro sensors for monitoring ocean acidification
Researchers have developed new technology that will measure pH levels in seawater for cost-effective, long-term monitoring of ocean acidification. Currently, it can be used for on-board analysis of seawater samples, but the goal is to develop the technology so it can be deployed for long periods of time in the ocean. This technology seems to have come at just the right time. A major new international report concludes that the acidity of the world’s oceans may increase by around 170 percent by the end of this century. Learn more here.
