There are about 4,000 reef fish species accounting for approximately a quarter of all fish species.

Nearly 60 per of the world’s remaining reefs are at risk of being lost in the three decades.

Coastlines

The total length of the coastlines is about 315,000 enough to circle the Equator 12

As coastal zones become and more crowded, the quality of water will suffer, the will be displaced, and the shorelines erode. 60% of the Pacific and 35% of the Atlantic shoreline are eroding at a rate of a every year.

Fisheries

The sea provides the biggest of wild or domestic protein in the Each year some 70 to 75 tons of fish are caught in the Of this amount around 29 tons is for human consumption. The fish production exceeds of cattle, sheep, poultry or Fish can be produced in two ways: by and by aqua culture. The total has grown 34% over the last

The largest numbers of fish are in the Southern Hemisphere due to the fact these waters are not largely by man.

Fifteen out of seventeen of the largest fisheries are so heavily that the reproduction can’t up. With the result that fish populations are decreasing

Species of fish endangered by are: tuna, salmon, halibut, and cod.

In the 19th century, codfish up to 200 pounds used to be caught. a 40 pound cod is considered a giant. overfishing.

Rising Sea Level

The sea has risen with an average of inches (10 to 25 cm) over the past 100 and scientists expect this to increase. Sea levels will rising even if the climate has because the ocean reacts to changes.

10,000 years ago the level was about 330 ft (110 lower than it is now.

If all the ice melted, the oceans would 200 ft (66 mtr).

Volcanic Activity

90% of all activity on Earth occurs in the The largest known concentration of volcanoes (approximately 1,133) on the sea is located in the South Pacific

The density of ocean water It becomes more dense as it colder, right down to its point of -1.9 degrees C. is unlike fresh water, is most dense at 4 degrees C, above its freezing point.)

temperature

Under the enormous of the deep ocean, sea water can very high temperatures boiling. A water temperature of 400 C has been measured at one hydrothermal

The average temperature of all ocean is about 3.5° C.

Almost all of the ocean temperatures are only a warmer than freezing

Ice

Antarctica has as much ice as the Atlantic has water.

10% of the earth’s surface is with ice.

The Arctic is the smallest ocean, holding one percent of the Earth’s seawater. is still more than 25 as much water as all rivers and water lakes.

The average of the Arctic ice sheet is about 9 to 10 although there are some as thick as 65 feet.

In the unlikely that all the polar ice were to the sea level all over the world rise 500 to 600 feet. As a result, 85 to 90% of the surface would be covered water as compared to the current The U.S. would be split by the Sea, which would the Great Lakes with the of Mexico.

The Arctic produces 10,000 to icebergs annually. The amount in the Antarctic regions is inestimable. normally have a four-year they begin entering lanes after about years.

Carbon Dioxide

Oceans absorb between 30% and 50% of the dioxide produced by burning fuel. Carbon dioxide is downwards by plankton. Any change in the of the ocean water, influences the of plankton to take up carbon This has consequences for the ecosystem, plankton form the base of the web.

Reefs

Over 60% of the coral reefs are threatened as a of pollution, sedimentation and bleaching due to water temperatures caused by warming. Global Coral Network (GCRMN) states currently 27% of all coral reef has disappeared and around 2050 30% will be left.

Oil

Oil is one of the ocean’s resources. It gives us heat for our endless consumer products, and the to run the engines of cars. planes, and for auto transport all over the Nearly one-third of the world’s oil from offshore fields in our which, as we’ve seen can devastating effects on our ocean’s The transport of ocean oil from the Gulf, The North Sea, and the of Mexico reaches all corners of the on a daily basis.

Oil was also from the sea. Millions of ago, countless marine plants (phytoplankton) and animals lived in the ancient seas as do today. As they died, the remains of these tiny settled to the sea floor, mixed mud and silt, and over millions of formed organic-rich sedimentary Other sediments continued to be and further buried the organic-rich layer to depths of thousands of compressing the layers into a that would become the for oil. Over the years, as the of the burial increased, pressure along with the temperature. such conditions, and over periods of time, the original remains of phytoplankton and zooplankton breaking down into substances called hydrocarbons compounds of hydrogen and carbon. process still continues, it will be millions of years the next batch of oil is done

Salinity

Some scientists that the oceans contain as as 50 quadrillion tons (50 million tons=50,000,000,000,000,000) of dissolved solids. If the in the ocean could be removed and evenly over the Earth’s surface it would form a more than 500 feet m) thick, about the height of a office building.

The ocean’s dissolved solids are sodium (sodium chloride or common calcium salts (calcium or lime, and calcium sulfate), salts (potassium sulfate), and salts (magnesium chloride, sulfate, and magnesium bromide).

sea water is heavier than sea water due to its higher salt

The freezing point of sea water on its salt content. Typical water has about 35 grams of per liter and freezes at -19 degrees C.
