3. Salty, Deep Surprises

You know what's salty, deep, and full of surprises? No, not your favorite bag of chips or that overrated crime documentary - it's the ocean, of course! Ready to dive into some knowledge?: Almost all of Earth's water (96.5 percent) is saline and found in the oceans, while only 2.5% is freshwater, essential for the survival of humans, plants, and animals. Of that tiny percentage, most is trapped in ice and ground, leaving just 1.2% for surface water use, and rivers holding a measly 0.49% of the freshwater pie.

10. Ocean's Sound-Whisperer

Step aside, fiber optics, there's an old-school sound-whisperer under the sea: The SOFAR or SOund Fixing And Ranging channel, nestled deep within the ocean, acts as a natural acoustics tunnel for sounds, enabling them to travel far distances with minimal signal loss. Discovered during WW2 for locating explosion sources, it now helps researchers observe chatty marine critters and seismic rumbles.

12. White Cliffs' Underwater Origins

Before the White Cliffs of Dover became Earth's ultimate color swatch: these towering chalky wonders were the underwater resting place of ancient party animals called coccolithophores. These microscopic algae donned calcite plate armor, living life to the fullest until they inevitably met their demise and sank to the bottom of a shallow sea, eventually compacting into layers of chalk which were later hoisted above sea level by the clever antics of plate tectonics.

13. Carbon Pirates of High Seas

Ahoy, carbon pirates! Navigating the high seas of climate change, the motley crew of ocean shipping is walking the plank of greenhouse gas emissions: In fact, maritime transportation accounts for 2.9% of global emissions, and with trade volume set to triple by 2050, organizations like the OECD and International Transport Forum are charting a course towards greener and more efficient shipping practices.

14. Salty Origins of Life

Hold your salty horses: When sea ice forms in the Arctic and Antarctic, it kicks out salt and ions in the process, creating high-concentration brine compartments within the ice. These compartments, coated with lipids, could have acted as primitive membranes and even provided the energy needed to create complex molecules like DNA, possibly sparking the origin of life.

15. Sunken Loot & Shipwrecks

Ahoy there, treasure hunters! Set sail for the Land of Wet Riches: there's a staggering $60 billion worth of sunken loot resting beneath the ocean waves, including glistening gold, sparkling jewels, and ancient weapons that would make Johnny Depp's Captain Jack Sparrow enviously drool. Yet, most of these shipwrecks are chilling close to coastlines, with many making port entryways their final watery resting place. But beware: diving for booty is a costly and uncertain pursuit, with only a small percentage of wrecks surveyed or visited by daring divers. Adventure and untold riches await... if ye be brave enough to dive into the unknown!

16. Ocean's Salad Bar

Who knew the ocean had its own salad bar? The marine life sure did: Kelp, a giant brown algae, grows up to 18 inches a day and creates dense underwater forests, providing food and shelter for a vast array of fish, invertebrates, and marine mammals - making it one of the most diverse, lively, and nutritious hotspots in the ocean world.

17. Renewable Ocean Energy

Why did the waves blush? Because the seaweed... and in their churning depths, they hid a boundless potential for renewable energy: Offshore wind power and ocean-derived energy sources like waves, currents, and tides have the capability to surpass our current energy needs, while marine protected areas – covering 6.35% of the ocean – actively defend coral reefs, mangroves, and bolster their resilience against climate change.

18. Skimming the Ocean Dyson-style

Oil be back: Skimming, the ocean's version of a Dyson vacuum cleaner, works to suck up oil from spills when the sea is calm and the slick is thicker than a milkshake. This method uses gadgetry that's oh-so-attracted to oil before depositing it into a collection tank, but remember, it's all about the "encounter rate" – our oceanic de-slicker has to cozy up to that oil before whisking it away in a less-than-pure oil-water mixture.

19. Poseidon's Tea Party

If Poseidon threw a tea party, he'd have the hottest kettle around: Ocean floor hydrothermal vents can release fluid that has been superheated within the Earth's crust, reaching temperatures of over 400°C, creating a unique habitat for organisms like the Pompeii worm, which can withstand temperature spikes of over 80°C.

20. Michael Phelps of the Marine World

Who would've thought that the "Michael Phelps" of the marine world actually has a taste for fast food and enjoys binge-watching its prey in every ocean on the planet? As ironic as it may seem, these black-and-white speedsters aren't the ocean's heavyweight champs: Killer whales, or orcas, may be apex predators with a diverse diet and unique hunting strategies, but they're not the largest predators around. They have a range extending across all oceans, but still face threats like food limitations, chemical contaminants, and disturbances from vessel traffic and sound.

21. Cuvier's Beaked Whale GPS

Who needs a submarine when you have a Cuvier's beaked whale GPS? These deep-ocean navigators put Jules Verne's Nautilus to shame: The record for the deepest dive by a Cuvier's beaked whale is an astonishing 2,992 metres, though they typically prefer strolls at merely 2,000 metres. Sperm whales also dive deep into the abyss, reaching 1,000 to 2,000 metres on the regular. Talk about ocean-sized lungs!

22. Undersea Bioluminescent Rave

Are you feeling left in the dark about the ocean's nightlife? It's time to glance at the undersea rave that never turns off its party lights: Over 80% of animals living between 200 and 1,000 meters in the pelagic zone emit their own bioluminescent glow, which is more common in the ocean than on land. Ranging from violet to green-yellow, these disco denizens – including fish, squid, jellyfish, and siphonophores – use their dazzling display to find food, attract mates, and avoid predators.
