Would you ever live “unda the sea” for a whole month? That’s what some explorers plan to do.

DEEP is an ocean exploration technology company. Its employees created the Sentinel Habitat System. It could allow scientists to live in and study the underwater world.

Here’s how it would work. Instead of taking a few short diving expeditions, a crew of six would board a submersible base and dive down deep—650 feet! They’d stay under for nearly a month at a time. You can think of the base kind of like the International Space Station. It’s a large lab where astronauts live and work.

The base is stationary. It doesn’t move around once it reaches the right depth.

The DEEP designers made the habitat to be rearrangeable. Rooms can be completely moved, removed, and added without affecting other parts of the system. Imagine being able to move your room anywhere in your house!

Sean Wolpert is the president of DEEP. He says the goal of the Sentinel System is to make humans aquatic. No, not as in growing fins and gills. DEEP’s goal is to create a system in which researchers can freely explore more of the ocean.

“It’s estimated around 40 to 50 percent of the seabed has not even been seen by human eyes or by robots either,” Mr. Wolpert says.

Why? Partly because the deep ocean exerts too much pressure for people to go to its deepest parts. Plus, even regular deep diving gets pretty pricey. It’s hard to see more than one hundred feet without using some expensive equipment. Surveying the ocean floor can cost millions.

In His hand are the depths of the Earth, and the mountain peaks belong to Him. The sea is His, for He made it, and His hands formed the dry land. — Psalm 95:4-7

Why? We can’t see all the beauty of God’s creation. But our appreciation of it only grows as we explore and dive deeper.
