Revealing the Secrets of OTZ
AN ALWAYS ON, ALWAYS CONNECTED OCEAN TWILIGHT ZONE
DATA MULES

Although there are gigatons of fish in the Ocean Twilight Zone, surprisingly little is known about them. With a generous gift from the Happel Foundation, WHOI scientists are building the first long-term observation network that will provide an around-the-clock view of life in the twilight zone, over an area spanning more than 155,000 square miles (250,000 square kilometers).
