ocean mapping is made possible through indirect methods. Oceanographers use echo sounding, sonar, radar, and seismographic surveys. Vibrations such as sounds are set down from the ocean surface. The vibrations are then reflected from the ocean bottom at the same angle that they are received and are recorded at the surface. To calculate the distance to the bottom, the following equation is used
d= 1/2 t x v
What else can I help you with?
Did aerial and satellite photography make possible the complete mapping of Antarctica?
These photographic technologies made possible the complete mapping of the ice sheet that covers 98% of the continent. Mapping the physical attributes of the continent uses other technologies, including geo-mapping technologies.
Why do they use sonar mapping?
Sonar mapping is needed for ocean research patterns.
Who is known for mapping the bottom of the ocean?
like mountain
Echolocation for mapping the bottom of the ocean?
the echolaocation for measurnig the bottom of the ocean is the Doppler effect
Who invented echo-sounding devices for mapping the ocean floor?
I think that Henry Hess invented echo-sounding devices for mapping the ocean floor. But I am not 100% sure that is the correct answer. LOL <3
What made the underwater exploration of the mid ocean ridge possible?
Developments in sonar, both depth-profiling and side-scan, and in sea-bed mapping generally for the overall topography, and in remotely-controlled submersibles for studying details. The adjective "underwater" isn't needed, BTW! :-)
What early 1900s development using sound waves made mapping the topography of the ocean floor easier?
SONAR, which was developed by the military to detect submarines.
What has most made the true exploration of the ocean possible?
Bathyscapes and submersibles have.
Did the scientists Henry Hess invented echo-sounding device for mapping the ocean floor?
no
Is it possible that there could be a deeper part of the ocean that has yet to be discovered?
Yes, it is possible that there are deeper parts of the ocean that have not yet been discovered. Scientists continue to explore and map the ocean floor, and new discoveries are still being made.
What inventions made sea travel possible in 1492?
The invention of the Portuguese ship, the caravel, made travel across the open tropical ocean and against the wind possible in 1492.
Which made Chinese exploration of the Indian Ocean possible?
advances in sailing and shipbuilding techniques(study Island)
