How is seafloor measured?
In a basic, single-beam sonar system, a combined transmitter and receiver, called a transducer, mounted on the bottom of a ship generates a single sound pulse. The pulse travels downward through the water, reflects off the ocean bottom, and then returns to the surface where it is detected by the transducer.
Where is the youngest seafloor?
Seafloor is youngest near the mid-ocean ridges and gets progressively older with distance from the ridge. Orange areas show the youngest seafloor. The oldest seafloor is near the edges of continents or deep sea trenches.
Can you walk on bottom of ocean?
Scuba divers can walk on the floor of the ocean, at the depths they can access. It is usually easier and faster to swim, however. Generally, once the depths become REALLY significant, humans have a hard time surviving the pressures. But at any depths divers have accessed, it is possible to ‘walk’ on the ocean floor.
How accurate are satellites?
Satellites transfer location information to your device through radio waves. It’s accurate for 7.8 meters, 95% of the time.
How far can I see on the ocean?
about 5 kilometres
How far can satellites see?
Many of the details about this class of satellites remain classified, but it is known that there are several of these overhead at any given time. They have an imaging resolution of 5-6 inches, which means they can see something 5 inches or larger on the ground.
Why does the ocean look bumpy on Google Maps?
Unusual grid patterns seen on maps of the ocean floor are created by ships taking higher-resolution sonar readings — to create better maps! The lines seen here show the paths taken by ships using sonar to map small sections of the ocean floor in greater detail.
Why is the water around the Bahamas so blue on Google Maps?
The waters around the Bahamas are light blue because the water is shallow. The light blue is a response to sunlight reflecting off the sand and corals on the bottom. You can sometimes gauge the depth of the water by the lightness or darkness of the blue waters. This blue hole is dark because it is very deep.
Why is the water around the Bahamas so blue?
The blue color of the ocean comes from the absorption of red and green light wavelengths by the water. The blue is reflected to be received by your eyes and the light blue is a response to sunlight reflecting off the powdery white sands and corals on the bottom.

Why is tropical water so clear?
The water is clear due to the absence of plankton and suspended particles. Plankton is the base of the food web in all oceans and, because there is little plankton in the tropics, tropical ocean water is nearly sterile in comparison with the fertile waters of the temperate oceans.
Why is Bora Bora water so blue?
The delightful illusion is created by the interplay of light, water and the brilliant white-sand, which carpets the depths of the lagoon. The best way to really experience these gemlike shades of blue is by crossing Bora Bora’s lagoon. The marine life in Bora Bora is equally exceptional.
