Caretakers of their waterways: Two Nova Scotians granted visionary awards

Caretakers of their waterways: Two Nova Scotians granted visionary awards

As you read this, tom cod are pushing through mud-dark water and gathering in the thousands at the head of the Minas Basin. They are driven blindly through the churning turbid water of the world’s highest tides by some ancient memory we can only understand by contemplating the moments we’ve felt instinct grab hold of our own bones. Waiting for them six days a week in an open aluminum boat are Darren Porter and daughter Erica. They’ll be there hauling and downloading the data from receivers, tagging fish and checking for signs of failed struggle until the ice chokes them off the water in January. “When you’ve spent enough time here you start becoming part of the ecosystem,” said Porter.

Research finds fishing gear a major source of ocean microplastics in Atlantic Canada

Research finds fishing gear a major source of ocean microplastics in Atlantic Canada

Two years ago, researchers collected microplastics from pristine surface waters at three nearshore locations in Nova Scotia and Newfoundland, finding tiny and unrecognizable fragments, threads and fibres in every trawl. Chemical analysis has now identified the synthetic polymers that made up those miniscule pieces of plastic and confirmed what was expected: the microplastics were shed from easily recognized sources. "Fishing gear, fishing rope, fragments of nets and particles that would come from that kind of activity, that is a big source of microplastics," said Ariel Smith, the coastal and marine team lead for Coastal Action, the environmental group that is leading a three-year Atlantic Canadian microplastics research project.
