The climate crisis has given us all a renewed appreciation for our planet's oceans and the marine life that lives beneath the water's surface, as well as ocean conservation projects led by initiatives like the TreadRight Foundation. These 10 unbelievable ocean facts illustrate just how important these initiatives are.

1. Our oceans cover more than 70 per cent of the Earth's surface.

With so much of the Earth's surface taken up by ocean, it's evident how vital these marine environments are to the planet, and how much there still is to be explored.

2. The majority of life on Earth is aquatic.

As so much of the Earth's surface is underwater, it comes as no surprise that marine species outnumber those on land. But, it's an incredible 94 per cent of the Earth's living species that exist within the oceans.

3. Less than five per cent of the planet's oceans have been explored.

According to the Ocean Service, man has explored less than five per cent of Earth's oceans. As researchers strive to discover more, we're continually getting to know our oceans better.

4. The world's longest mountain chain is underwater.

Earth's longest chain of mountains, the Mid-Ocean Ridge, is almost entirely beneath the ocean, stretching across a distance of 65,000 kilometres. It's said that this mountain chain is less explored than the surface of Venus or Mars.

5. There are more historic artefacts under the sea than in all of the world's museums.

Around 1,000 shipwrecks lie off the Florida Keys alone, some of which are within the Florida Keys National Marine Sanctuary. Other underwater museums have been created in recent years, including the Mediterranean's submerged bronze statue, Christ of the Abyss.

6. We still only know a fraction of the marine species in our oceans.

According to the World Register of Marine Species there are now 240,470 accepted species, but this is believed to be just a small proportion of the species that exist, with new marine life being discovered everyday.

7. Over 70 per cent of our planet's oxygen is produced by the ocean.

It's thought that between 70 and 80 per cent of the oxygen we breathe is produced by marine plants, nearly all of which are marine algae.

8. It's possible to find rivers and lakes beneath the ocean.

When salt water and hydrogen sulfide combine, it becomes denser than the rest of the water around it, enabling it to form a lake or river that flows beneath the sea.

9. Around 50 per cent of the US lies beneath the ocean.

Not only does a large part of the planet exist beneath the ocean, so does the United States - around 50 per cent, in fact.

10. The Pacific Ocean is the world's largest ocean and contains around 25,000 islands.

With 25,000 islands lying within it, the Pacific Ocean has more islands than anywhere else on the planet.

When you picture a marine biologist, what comes to mind? Perhaps a dolphin trainer or Jacques Cousteau? The fact is, marine biology covers a wide range of activities as well as aquatic organisms-and so does the job of a marine biologist. To find out what a marine biologist is, what marine biologists do, and how you can follow that career path should you decide it's for you, read on.

What is a Marine Biologist?

Marine biology is the study of plants and animals that live in saltwater, therefore, a marine biologist is someone employed in that field of study. However, the more you think about it, the more you'll realize that the umbrella term "marine biologist" is a very general one that encompasses pretty much anyone on a professional level who studies or works with things that live in saltwater.

While some marine biologists do study and train whales and dolphins, the vast majority pursue a wide range of other activities, including everything from fish, crustaceans, and seals to sponges, seaweed, coral, and other deep-sea creatures including tiny plankton and microbes.

While the term "marine biologist" is very general, those who work in the field usually have more specific titles, depending on what they do. For example, an ichthyologist studies fish, a cetologist studies whales, a microbiologist studies microscopic organisms.

Some tools used to study the biology of marine organisms include sampling tools such as plankton nets and trawls, underwater equipment such as video cameras, remotely operated vehicles, hydrophones and sonar, and tracking methods such as satellite tags and photo-identification research.

Where do Marine Biologists Work?

Some marine biologists focus on a single species, while others look at larger environments and habitats. A marine biologist's job may involve fieldwork, either in or on the ocean, a salt marsh, a beach, or an estuary, again, depending on their specialty.

Marine biologists may work on a boat, scuba dive, use a submersible vessel, or study marine life from shore. Or, they might work in a combination of places, starting out by collecting specimens, and then taking them back to an aquarium, where they can observe and care for them, or to a lab for use in a variety of study applications, including DNA sequencing and medical research.

In addition to fieldwork, marine biologists teach at colleges and universities and are also employed by government agencies, non-profit organizations, privately-owned businesses, aquariums, and zoos.

Educations and Experience

To become a marine biologist, you will likely need, at a minimum, a bachelor's degree, and possibly a graduate degree, such as a master's or Ph.D. Science and mathematics are important elements of a marine biologist's education, so you should apply yourself to those fields as early as you can-high school, or even sooner.

Since jobs in the marine biology field are competitive, it will be easier to get a position if you've already gained relevant experience during high school and college. Even if you don't live near the ocean, you can get relevant experience. Work with animals by volunteering at an animal shelter, veterinary office, zoo or aquarium. Even experience not working directly with animals in these institutions can be helpful for background knowledge and experience.

Reading and writing well are important skills for a successful career as marine biologists. If you decide to pursue this career, you'll be required to read a great deal of course material and be expected to write substantive reports to indicate you understand the material. Take as many biologies, ecology, and related courses in high school and college that you can, and be open to learning about new technology.

According to advice from Stonybrook University (which has an excellent marine biology department), you might not necessarily want to major in marine biology as an undergraduate, although it's often helpful to pick a related field. Classes with labs and outdoor experiences offer great hands-on experience.

Fill your free time with volunteer experience, internships, and travel if you can in order to learn as much about the ocean and its inhabitants as you can. This will give you lots of relevant experience that you can draw upon when applying for grad school or jobs in marine biology.

How Much Does a Marine Biologist Get Paid?

Positions are competitive, and as a result, a marine biologist's salary may not necessarily reflect all of their years of schooling and/or experience. However, in exchange for relatively lower pay, many marine biologists enjoy working outside, traveling to beautiful places, and not having to dress formally to go to work, as well as being able to make a positive impact on science and the world while generally loving what they do.

The salary of a marine biologist depends upon their exact position, their experience, qualifications, where they work, and what they are doing. Pay can range from a volunteer experience as an unpaid intern to an actual salary of anywhere from $35,000 to $110,000 per year. According to the U.S. Bureau of Labor Statistics, as of 2016, the median annual salary for an established marine biologist was about $60,000.

Marine biologist jobs considered more "fun" (i.e., with more time in the field) may pay less than others as they are often entry-level technician positions that are paid by the hour. Jobs that entail increased responsibility will likely mean that you'll be spending more time inside working at a computer.

James B. Wood, a marine biologist working at the Bermuda Institute of Ocean Sciences, reported in a 2007 interview that an average salary for marine biologists in the academic world was in the $45,000 to $110,000 range-although he cautions that much of the time marine biologists must raise those funds themselves by applying for grants.

Finding a Job As a Marine Biologist

Sadly, as many jobs in marine biology are dependent on governmental funding and grants, growth opportunities are not as abundant as they might once have been. That said, there are still many online resources for job-hunting, including career websites.

You can also go directly to the source-including websites for government agencies (for example, related agencies such as NOAA's career web site) and the career listings for departments for universities, colleges, organizations, or aquariums where you'd like to work.

The best way to get a job, though, is by word-of-mouth or working your way up to a position. Through volunteering, interning, or working in an entry-level position, you're more likely to learn about available job opportunities. The people in charge of hiring might be more likely to hire you if they've worked with you before, or if they get a stellar recommendation about you from someone they know.

Charles Robert Darwin, (; 12 February 1809 - 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.Darwin published his theory of evolution with compelling ...more on Wikipedia
