The oceans are perplexing with a sense of mystery.

It is one of the most perplexing things about the ocean, its not just its sheer size and immensity how far the depths in parts of this world reach, rather it can be noted and etched in fact that one of the most profound aspects of the ocean has been explained or interpreted over the many centuries up to the present time.

Indeed if we take a look at the deepest known part of the ocean, the Marianna Trench situated in the Pacific Ocean, we began to realize its perplexity and even its mysteriousness.

While this part of the ocean is approximately is 11 000 metres (36,1000 feet) deep, this depth, explored by an underwater vessel named the Trieste, a United states expeditionary ship in 1960, specially designed to go these extreme depths and withstand immense pressure on its hull.

Equally, this is truly an explorative adventure that is quite immense as the results on either man a machine because humans are not physically capable of depths of these magnitudes and up until that point neither was a submersible machine.

The physiological capability and implications of diving this deep is fraught with complications, high pressure and freezing waters at this depth alone and the mere absence of light is just too much for humans to bear unassisted by machine.

So back then the explorers of the Trieste mission Lt Donald Walsh of the United States Navy and oceanic explorer Jacques Piccard braved these extreme depths in the pursuit of research and exploration and to gather observations down in the Marianna Trench, a voyage which took 5 hours to reach 11,000 metres, a depth that has until this day never been ventured again.

However there have been many other notable and formidable explorations of this type and scope in ocean-going submersibles over the years, so we can expect to see more expeditions of this nature as technology and knowledge increases over time and the permittance of financial resources to such expeditions.

Certainly, these forays into the deep ocean brought more revelations and observations that it explained not only the other many boundless oddities and obscurities of this watery planet but also these limitations of both knowledge and physiology of humans.

The early exploration of the oceans has been accomplished by many in the modern era notwithstanding the oceans large surface area, explorers researchers and different cultures amongst many other vocations and backgrounds have historically taken to the oceans for discovery or curiosity via the use of technology that propelled many early civilizations to traverse the oceans.

Again, the modern era and all its technological advancements and the burgeoning use and application of it in the seas and oceans to observe and measure life and processes in the planet ocean have been a marvel of human endeavour.

Technological advancements in transportation have given as further and farther access, we can now cross may oceans and seas in a relatively short period even though the oceans and its wildest depths remain largely unexplored and even unknown by implication.

Similarly, satellites and spacecraft can map and research parts of our ocean from the orbit of from outer space, however strangely enough mapping of the ocean is quite underdeveloped up until this day, more resources and years have been spent mapping our moon rather than tho oceans.

Another important factor which is readily observable is world trade and passenger traffic whether it be aircraft or boats the oceans provide and facilitate a rather efficient way to move people and things around as well. The bolstering of communication, interaction and intermingling of cultures has been another positive aspect brought about the dawn of discovery and exploration.

The oceans are perplexing, from its unknown depths to its unknown marine life that is yet to be discovered. The fact that is allows a vast network of transportation to crisscross the world in such a seemingly short time when we consider the time spent at sea or in the air to arrive at your respective destination.

Moreover to the many machines built with the explicit purpose to maintain and strengthen the exploration of our oceans., if we consider just these things alone, then the oceans and seas have not only provided this facility but also endowed it with future exploration, discovery, curiosity and adventure.
