Congratulations to MBL’s Linda Amaral Zettler and colleagues, whose paper introducing the “Plastisphere” has been named “First Runner Up: Best Environmental Science Papers of 2013” by the journal Environmental Science & Technology. The journal’s editors selected the winners from more than 1,730 papers it published last year on a range of topics in environmental science, technology, and policy.

The Plastisphere, a novel ecological habitat, is the flotilla of microbial communities attached to bits of plastic debris in the ocean. Amaral Zettler collaborated with Erik Zettler of Sea Education Association and Tracy Mincer of Woods Hole Oceanographic Institution to collect the samples (most of which were millimeter-sized pieces of plastic) in the North Atlantic Ocean and analyze their microbial passengers. The Plastisphere, they say, raises a host of questions. How does it change environmental conditions for marine microbes and their competion for survival? How does it change the ocean ecosystem and affect larger organisms? Does it change where microbes, including pathogens, are transported in the ocean? Because plastics are so long-lived, the scientists say, they may play a significant role in distributing bacteria in the ocean.
