Follow the International Fund for Animal Welfare on their purpose-built research vessel, the Song Of The Whale, to the whale feeding and nursing grounds off the coast of Massachusetts. They join a team from NOAA (National Oceanic and Atmospheric Administration) to undertake a first of its kind project to collect a full 24 hours of data from tagged humpback whales. The mission is to learn what these magnificent creatures, especially mother and calf pairs, do at night below the surface. For more info, visit: ifaw.org
