You can consider this installment four of my previous question which is the third installment.
Throughout history, we have developed many methods of telling time. The most famous two examples being the clock and the sundial. The ancient Egyptians invented the clepsydra, an extremely simple device that uses dripping water as a way to tell how much time has passed. There are also, for example, hourglasses, which flow sand as a measurement of time.
Suppose, though, you were an intelligent dolphin and, for some reason, had to always have a time reference on you. Being under the water seems to present a challenge, for technology like clocks and hourglasses don’t seem to be possible to make under the water, a clepsydra certainly wouldn’t work since you can’t pour water underwater, and a sundial wouldn’t have the proper lighting. So you must improvise in order to find a way to keep track of time. How would you improvise in order to keep track of time.
🐬 Improvised Underwater Timekeeping for Dolphins:
An intelligent dolphin could adapt to underwater timekeeping by observing natural cycles, biological cues, and marine phenomena. Here’s how:
Harnessing Natural Rhythms
• Tidal Changes: Dolphins could monitor the ebb and flow of tides, which occur predictably based on the lunar cycle. Changes in water current speed, temperature, or pressure could serve as cues for time measurement. • Day-Night Cycles: Despite being underwater, ambient light penetration varies with time of day. Dolphins with sensitive vision could detect shifts in light intensity or color. • Marine Sounds: The ocean environment is rich with natural sounds that vary throughout the day, such as coral reef activity during daylight hours or nocturnal hunting sounds.
Biological Cues
• Internal Circadian Rhythms: Dolphins have well-developed biological clocks that could help them estimate time intervals based on their innate circadian rhythms. • Heartbeat or Breathing Patterns: They could track their heart rate or breathing intervals to measure short durations.
Environmental Markers
• Bubble Streams: Dolphins could use their breath to create bubble trails or patterns and observe their rise time or behavior as a rough timing mechanism. • Floating Particles: They could monitor the sinking or rising of particles like algae or debris to estimate time.
Intelligence and Communication
• Echo-Location as a Timer: Dolphins use echolocation effectively. They might develop a way to measure time based on how long sound waves take to bounce back from consistent underwater structures. • Social Synchronization: In groups, they could rely on collective signals, such as patterned clicks or whistles, to denote the passage of specific intervals.
Innovative Tools
• Natural Hourglasses: They could manipulate objects like sediment-filled shells, observing how long it takes particles to settle or rise when shaken. • Thermal Layers: Dolphins could detect thermal gradients or changes in water temperature at specific times of day.
I was also immediately thinking of tides as a time measurent. Relying on moon cycles gets you out of sync with solar years pretty quickly (os thqt important underwater? You probably do get seasonal changes?), I wonder if you could detect sunlight intensity changes or something and then do the whole solar / lunar calendar leap-day shebang we do …
