Seeker, in partnership with Discovery and produced in association with Nomadica Films, has announced a new expedition called "The Swim." The expedition features long-distance swimmer Ben Lecomte as he swims the Pacific Ocean in an effort to gain awareness on the state of ocean health from pollution.

As Ben Lecomte focuses on his goal to swim across the Pacific Ocean, see how the Seeker research team is collecting data on everything from plankton to plastic to singing whales.

We look at the role of ocean currents the Seeker crew used to plan the ideal route across the Pacific.

As Ben Lecomte slowly swims across the Pacific Ocean, the Seeker crew records audio underwater for a view into marine life that's never been done for this long.

We look at how Ben's body might change by the end of his swim. How does this compare to an astronaut in space?

The Swim took many years to plan. See how the Seeker crew prepared to live months on a boat, including making their own water, preparing meals, and changes in hygiene and sleeping.
