Our Changing World - Know Your Local Rocky Shore

Many of us have favourite local beach or stretch of coast that we visit regularly. But how well do we actually know it? The New Zealand Marine Studies Centre at the University of Otago is challenging people to get down and intimate with their local rocky shore and really find out what's there. The challenge is called Marine Metre Squared - science communication student Gerard Barbalich heads to the beach with Sally Carson and Kimberley Collins to find out how it works.
