Beaked whales are the most mysterious of all marine mammals. So far, there are about 20 species known around the world. They inhabit deep, pelagic waters spending very little time at the surface. As a consequence, scientists are developing technologies to learn more about these elusive toothed whales. Mark Johnson has designed a non-invasive way to study them using a device called the DTAG.

Whales of the Mediterranean Sea is an original five-part educational documentary film produced by Chris and Genevieve Johnson that ventures into deep seas and coastal waters with a range of international scientists.

Scientists estimate that 150 Vaquita remain. This shy, elusive porpoise is disappearing due to accidental entanglement in fishing nets set for shrimp.

The Voyage of the Odyssey was a 5.5 year global scientific and education expedition studying sperm whales and ocean pollution. Chris & Genevieve Johnson of earthOCEAN Media produced the award-winning online series for PBS live from the field.

The Ocean Alliance is dedicated to the conservation of whales and their ocean environment through research and education. The Royal Melbourne Zoo is a leading international educational institution in Melbourne, Australia.

With the popularity of the PBS web series, the Voyage of the Odyssey – Chris and Genevieve Johnson of earthOCEAN developed the Ocean Encounters education initiative – a series of videos, images and sounds presented on DVD with educators from the Melbourne Zoo.
