Last winter, a team of divers braved Tasmania's icy eastern waters to help give the region's spectacular giant kelp forests a fighting chance.
Under the waves, the volunteer divers strung lengths of twine adorned with juvenile kelp to the root-like bases of other seaweeds.
It's a restoration technique developed by Institute for Marine and Antarctic Studies scientists over several years that has already been used successfully to repair patches of the towering forests.
