What exactly is a marine biologist? What do they actually do?
It turns out they aren’t just a bunch of people who enjoy swimming and looking at underwater creatures with a snorkel and fins. I feel like this is one of those careers that sound so arbitrary and mystifying that we don’t take the time to find out about it or pay attention to it. It turns out their job is not as abstract and insignificant as space lawyers, extreme unicyclists or penguinologists.
Marine biologists actually study for a long time to acquire the necessary skills to study and observe underwater habitats and creatures. They are responsible for the discovery of many weird, wonderful and wacky sea creatures. They play a vital role in teaching us how to maintain and preserve this incredible source of food, medicine and raw materials that can help us build our future. By studying the natural habitats of sea plants and creatures, they are able to predict changes that we may experience in the future due to climate change and other factors. They have great ideas when it comes to preserving and sustaining this source and quite frankly, I feel they should be given a round of applause. Their job is pretty cool and very necessary for all of us!
Marine biology can be defined simply as the scientific study of organisms in the ocean or other marine bodies of water. The ocean covers approximately 71% of the Earth’s surface thus providing for extensive study and research. Because such a large portion of life on Earth is found in the ocean, it is understandable that there is still an enormous amount of species yet to be discovered!
The study of the ocean ranges from tiny surface layers of water where organisms may be trapped to the depths of the oceanic trenches. Can you imagine how deep the ocean actually is? This is something that I cannot wrap my mind around. To put it into perspective, sunlight can only reach up to 1000m, 1,828m is the lowest point of the Grand Canyon, 4,267m is the average depth of the ocean, but it is deeper still! The height of Mount Everest is 8,850m, and the ocean is deeper than this. It has been discovered that the bottom of the Mariana Trench is 11,034m deep! Now this is something I just cannot comprehend.
