In 1956 Vine convinced the United States goverment that scientists needed deep-diving vessels that could hold small crews.
the sea floor
because of the crabs that walk around on the sand of the ocean.
scientists actually believe that the megladon is alive and well. As for me, i don't know what to believe. Scientists think that it still lives in the Indian ocean, which is off the coast of India.
Well, we can't give you an exact number, because new species of ocean animals are being discovered by scientists every day! We are still a long way from knowing everything about the Ocean, so on a rough scale I would say over 100,000,000 species!
The frilled shark has lived for about 95 million years making it a living fossil.
The Youngest Ocean is the Artic Ocean Because People thought the artic ocean froze over and was just ice.
Alvin, and others like it, are unmanned, deepsea, robotic submersibles, designed to operate at the greatest ocean depths. It can dive, observe (visually and through various sensors), and sample the deep ocean environments, including living specimens, without endangering human life. These capabilities are extremely valuable in the exploration of our oceans.
Deep sea submersibles help get research from the ocean floor.
4,502 scientists have seen the deep ocean through Alvin"s windows.
Scientists have not been able to find a way to survive in the deep ocean with out a aqua lung and submersibles. So its scientifically impossible
With submersibles, sonar, magnetometers, and satellites.
no sonars areNo they are not, a sonar maps the ocean floor.
Bathyscapes and submersibles have.
Deep ocean floor samples can be obtained by submersibles.
hello
How scientists map the bottom of the ocean
Scientists know the depth of the ocean by using technology like the Deep Worker or the "Alvin". It takes them to the bottom of the ocean so they can study ocean life. Also ships use sonar (SOund NAvigation and Ranging) to see what the depth of the ocean is.
