It’s estimated that 200 million people make their living by fishing directly or indirectly.
71% of the Earth’s surface is covered by oceans

Less than 1% of living space on Earth is on land – the other 99% is in the oceans
Ocean water and ice make up 98% of all water on Earth
Oceans are home to innumerable species
Every square inch of the ocean habitable
According to the Food and Agriculture Organization (FAO) over 70% of the World’s fish species are either fully exploited or depleted
MORE THAN 80% of all life is found beneath the waves
Oceans creates over half of our oxygen
The average depth of the ocean is 2 miles- all of which is habitable.

80% of known life forms are marine.
33 Animal Phylaof which…
32 live in the ocean
12 live on land
Osha Gray Davidson, Fire in the Turtle House
50% of the world’s population lives within 50 miles of the coast
32 billion gallons of pollution enters the ocean everyday
Shipping-50% of international trade is hazardous materials
Everyday mishaps with oil rigs, seepage, discharge from ships and everyday chemical runoff from land sources = 15 million gallons of oil entering N. American oceans each year = 4,500 residential swimming pools
NASA spent $820 million on missions to Mars to look for water Compared to the approximately $600 million spent on ocean research on our own planet.
Marine Science can be defined as the study of the ocean, its ecosystems, and life forms; also called oceanography
Marine science consists of four branches of oceanography
Oceanography is the science of recording and describing the ocean’s contents and processes.
The four main branches of oceanography:Biological oceanography (Marine biology)
Chemical oceanographyGeological oceanographyPhysical oceanography
Biological oceanography (also called marine biology) studies the diversity of life in the ocean and the ocean’s role as their habitat.
Chemical oceanography studies the chemistry of seawater
Geological oceanography concerns itself with the geology of the ocean
Physical oceanography is the study of the physics within the marine environment
Marine science draws on physical science, life science, and Earth and space sciencePhysical science is the study of matter and
energy (chemistry and physics)Life science is the study of living things and
their interactions with their environment (physiology, biology, ecology)
Earth and space science is the study of the physical Earth, the solar system, the universe, and their interrelationships. (Geology, astronomy, astrophysics)
Because marine science is a broad field, marine scientist need more than a formal education in the sciences.mathematicsHistoryTechnologySocial sciencesLiteraturearts
Got Ocean?• The ocean covers 71% of the Earth’s surface• Accounts for >97% of the Earth’s water!
– That means that all the rivers, lakes, glaciers, rain, snow, and groundwater make up the <3% remainder!
• The average depth of the ocean is 3,800 meters (=12,500 feet) and at its deepest depth is 7,000 ft greater than the highest elevation on land (Mt. Everest 29,000 ft; Mariana Trench 36,163 ft)
• The average temperature of the ocean is only 3.9 AC (=39 AF)
OceanographyThe oceans are separated into 5 named ocean basins (and many smaller seas), but they all constitute one world ocean; one great intermixing mass of saline (salty) water
All oceans are, in fact, interconnected with one another

Why study Marine Science?~80% of all Americans live within 1
hour of an ocean or Great Lake100% of all Long Islanders live within
1 hour of the Atlantic Ocean (and that assumes a good deal of traffic…)
50% of the world’s population live on a coastline
