Into the Big Blue Heart: Ocean Currents

The East Australian Current creates life on land and at sea as we begin our ocean odyssey on the Great Barrier Reef. Microscopic plankton blooms, a clownfish finds his home, and a baby whale begins the journey of a lifetime.

As the East Australian Current flows through the subtropical zone, it sustains whole ecosystems. Vast kelp gardens provide refuge to a new host of creatures, and the current brings life to a remote island.

The East Australian Current brings a warm change to cool temperate ecosystems. As we follow our whales south, we discover the awesome biodiversity of Sydney Harbor, while Tasmania’s giant kelp falls victim to climate change.
