**Title:** Deep-Sea Dive on Research Ship Baseline Explorer
**Location:** Off the coast of Bermuda, North Atlantic Ocean
**Summary:**
* Onboard science reporter Greg Foot embarks on a deep-sea dive in a submersible vessel from the research ship Baseline Explorer.
* The dive begins with a descent into the ocean, reaching 200 meters, where sunlight is scarce (Twilight Zone).
* Foot provides commentary on the increasing water pressure (25 atmospheres at 250 meters) and the submersible's design (acrylic sphere) that withstands it.
* During the dive, he observes marine life, including a shark, Moray Eel, and a school of fish.
* The mission's purpose is revealed: conducting an ocean floor survey, highlighting that only about 0.0001% of the ocean floor has been explored.
* The dive concludes with a successful ascent to the surface, with Greg reflecting on the unforgettable experience.
Here are the extracted key facts, numbered and in short sentences, excluding opinions:
**Location & Environment**
1. The research ship, Baseline Explorer, is located off the coast of Bermuda in the North Atlantic Ocean.
2. The ship is 775 miles from New York and 1051 miles from Florida.
3. The current depth is below 200 meters, where sunlight is scarce.
**Dive & Submersible**
4. The submersible is an acrylic sphere designed to handle deep-sea pressure.
5. At 250 meters, the pressure is equivalent to about 25 atmospheres.
6. The submersible's spherical shape distributes pressure evenly, making it strong.
**Oceanography & Exploration**
7. Only about 10-15% of the ocean floor has been mapped to a certain resolution.
8. Less than 0.0001% of the ocean's deepest areas have been explored.
9. The ocean produces a significant amount of the world's oxygen and regulates global temperature.
**Specific Dive Details**
10. The dive reached a depth of 565 feet, showcasing incredible diversity.
11. Below 200 meters, the sunlight layer is left, entering the Twilight Zone.
12. At approximately 1000 meters, the Midnight Zone begins, characterized by total darkness.
**Miscellaneous**
13. The submersible's life support system is self-sustaining for a limited time.
14. Technical divers on the mission can dive for 5-6 hours at depths, with decompression time afterward.
