ZF_5_01 — Autonomous Underwater Vehicles and Ocean Exploration Technology
Ocean exploration technology — from early human-occupied submersibles to modern autonomous underwater vehicles (AUVs) — has progressively opened the deep ocean to scientific investigation, driving transformative discover
ZF_4_12 — Underwater Acoustics and the SOFAR Channel
Sound is the dominant long-range information carrier in the ocean — electromagnetic radiation (light, radio) is rapidly absorbed in seawater, but sound can travel thousands of kilometers with remarkably little loss, maki
D_5_01 — Art, Paintings & Alleged UFO/Alien Imagery
Ancient and medieval art worldwide contains imagery that some interpret as depicting aerial craft or non-human beings — from Tassili n'Ajjer's "round-headed beings" (~8000 BCE) to medieval paintings with disc-shaped obje
D_4_02 — Submerged Structures & Underwater Archaeology
Since the Last Glacial Maximum (~26,500–19,000 BP), global sea levels have risen approximately 120–130 meters, inundating an estimated 25 million km² of formerly habitable land — an area larger than North America. Any co
