SEA CHANGE 03.tif

Download
Heaven for a kina connoisseur, not so good for a flourishing marine ecosystem, a superabundance of sea eggs on the rocky seabed at the Chatham Islands indicates a food chain that has lost a vital link: predators. Insufficient numbers of carnivorous fish and rock lobsters—the legacy of historic overfishing—allows sea-urchin populations to skyrocket. The relentless grazers nibble algae down to the rock, creating underwater deserts known as kina barrens.
Shot on assignment for New Zealand Geographic Issue 130 November-December 2014.
