Scientists study ‘plastisphere,’ its role in ocean

Scientists have probed the diversity of life in all sorts of ecosystems, from the insides of our guts to the sediments beneath the ocean floor. Now, a small group of Massachusetts scientists is eyeing a new frontier: the flotilla of tiny pieces of plastic adrift on ocean surf.

A new study describes the “plastisphere” — the microbial communities that hitch rides on the confetti-sized bits of plastic that litter ocean waters. The authors discovered a thriving, miniature world aboard the microplastic “reefs,” where communities of bacteria and other microbes create energy from sunlight, reproduce, and prey on one another.
