Quick, when I say “ocean” what are the images that come to mind? Humpback whales breaking through blue water or maybe miles of coral reef guarded by brightly colored fish. But what if I told you that the smallest things, those that canâ€™t be seen with the un-aided eye, are also worthy of exploration. In the water running seaward and in the sand and mud at your toes â€“ there is life. Life that is responsible for the recycling of nutrients and sometimes the cleansing of water.
