🔄 Tides of Plastic: Microplastic Pollution in the Oceans and Its Journey Back to Us
From section: 🌊 From land to sea: how microplastics enter and move through the oceans… Transport patterns can create encounter zones where particles and marine life meet in surface waters, sediments, estuaries, and feeding grounds. Once the ocean has carried these fragments into the spaces where organisms live and feed, the story shifts from physical movement to biological contact.

🌊 Where the Salt Stays: Why the Ocean Is Salty but Rivers and Most Lakes Are Fresh
From section: Frequently Asked Questions+Does salt evaporate with ocean water? Most dissolved salts do not enter water vapor during ordinary evaporation. Water molecules escape from the surface, leaving the ions behind. Salt can still reach the atmosphere through breaking waves and sea spray, which produce tiny salt-containing droplets and particles.

🕸️ Ghost Nets, Silent Drifters: How Lost Fishing Gear Haunts the Ocean
From section: Frequently Asked Questions+How are ghost nets connected to microplastics? As synthetic nets age, sunlight, saltwater, abrasion, and wave action can weaken them into smaller fragments. Those fragments can contribute to microplastic pollution and may be ingested by fish, invertebrates, and other organisms.

🌍 When Earth First Took Shape: A Planet Born from Cosmic Dust
From section: 🌊 From fire to water: Cooling, oceans, and early atmosphere… Early Earth may have hosted a global or near-global ocean, although the timing, extent, and stability of those first oceans remain active areas of research.

🌐 How SONAR Uses Sound to Map the Hidden Ocean Depths
From section: 🐋 Listening to life in the oceanThis biological perspective connects back to the earlier discussion of sound propagation. The same physical principles that guide SONAR pulses also shape how animal sounds travel through the ocean, which provides a natural path toward understanding how SONAR technology developed over time.

🪐 K2-18 b: The Ocean World We Have Not Seen
One interpretation describes K2-18 b as a possible Hycean world, with a hydrogen-rich atmosphere above a global ocean. Other research finds that the same observations can be explained by a gas-rich mini-Neptune with no habitable surface. …

The Way a River Travels
A river does not travel by force alone. It moves by responding to the land that holds it, shaping itself to every rise and hollow, every bank and bend. Its journey is not a straight line but a long conversation between water and ground.

🌊 One Ocean, Uneven Salt: Why Salinity Does Not Simply Even Out
The Atlantic-Pacific salinity difference is clear on global maps: on average, the Atlantic has higher surface salinity than the Pacific. Yet these are not sealed reservoirs. They are regions of one connected global ocean, and currents continually transport water between them.
