Oceans and their Importance By: christian Reynoso Period: 3

Why are oceans important? Oceans are the lifeblood of planet Earth and humankind. They flow over nearly three-quarters of our planet, and hold 97% of the planet's water. They produce more than half of the oxygen in the atmosphere, and absorb the most carbon from it.
Why is it hard to study the ocean? 1) For starters, water is not transparent in areas of the ocean nor is it opaque, however unless extensive research is done on any area which is to be explored it would be a blind dive.
Reason 2) The inaccessibility, the amount of time and effort to get to an area which is to be explored will take time and work because of the length that would be traveled to get a a destined area
Reason 3) Pressure, at this point in time its a given to know the deeper in water you go the more pressure there is, which isn't an issue in modern days but is still always a hassle when dealing with deep sea exploration.
Reason 4) Conduction and corrosion of the water, making scientists have to make all devices and things waterproof to keep from malfuntioning
Reason 5) Wave motions make equiptment act inappropriately as well as affect the people on this ship
When did scientific research start on the ocean? Aristotle was the first scientist on record to actually do research on the ocean and is considered the father of marine biology.
What did they want to find? In the beginning of their research they only wanted to learn more of the ocean life it holds then later learned the keys to earth's origin may reside in the depths as well as information regarding ways to predict tsunamis, earthquakes, and most importantly, the origin of earth.
(no the one in the picture) The “sea bell” was the first form of underwater exploration brought forward that provided prolonged sessions, made by Guglielmo de Lorena in 1535 and was the first step towards improving underwater exploration
The “SCUBA” was invented which was really a modernized version of the sea bell only it allowed for longer session and was a full body suit made by an englishman William H. James. Although this was just a small step towards what we have today
The first deep sea dive was done in a steel ball which included glass holes to look through and lights. This was done by William Beebe and Otis Barton in 1934 The aqualung was made to prolong sessions even further and safer by Jacques Cousteau in 1943 (closest photo on spark)
Basically was just an improved version of the scuba, the aqualung was made to prolong sessions even further and safer by Jacques Cousteau in 1943.
(not actual picture) Alvin was later created and all it was was an underwater vessel/robot to avoid the danger of deep sea diving but still gathering required information made in 1964
All these ocean exploration advancements we've made all tie back to the fact that the sea holds the key to discover the origin of earth
Earth is made up of mostly water, scientists have been trying to figure out how we got all this water in the first place if earth was once just a ball of molten lava.
Through extensive research, there has been a rock found in the ocean that dates back 3.5 billion years ago that both produces oxygen and holds air. That alone tells us that water came from meteorites billions of years ago during the birth of our home, earth
