Pacific coast is colder than Atlantic coast.
The waters of the Pacific Ocean comprise the world's largest heat reservoir, by far, and it is the warmest ocean, overall, of the world's five oceans. (The other oceans are the Arctic, Antarctic and Indian Oceans.)
The Arctic Ocean is the world's smallest ocean. It is also the shallowest out of the five major oceans of the world. It covers an area of about 5,430,000 sq mi (14,060,000 km2) and is the coldest out of all the other oceans.
Arctic ocean swimming has long been practiced in Iceland but in recent years the trend has become increasingly popular with more people than ever taking a dip into the icy Atlantic Ocean.
A “supercoolometer”, a device that sounds like it should be used to measure hipsters, has found the coldest seawater on Earth, under Antarctic sea ice.
The quick answer to which side of Australia has warmer waters is the Northern coast in the Northern Territory with temperatures lingering around 28 to 32 degrees Celcius all year round.
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.
But as in weather, where there are areas of high and low pressure, the ocean has areas of high and low salinity. Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease in salinity near the equator and at both poles, although for different reasons.
The South Pacific is the least polluted of the world's oceans. There are about 150 million metric tons of plastic in the oceans and a further 8 million metric tons are added to the oceans annually.
Since the Pacific Ocean covers more of the equatorial area than any other, it is sometimes cited as the calmest ocean, overall.
The largest iceberg on record was an Antarctic tabular iceberg measuring 335 by 97 kilometres (208 by 60 mi) sighted 240 kilometres (150 mi) west of Scott Island, in the South Pacific Ocean, by the USS Glacier on November 12, 1956. This iceberg was larger than Belgium.
With its unique combination of salt and minerals, swimming in the Dead Sea is a one-of-a-kind adventure. Not only will you float effortlessly in its buoyant waters, but you'll also reap the benefits of its therapeutic properties.
In the water of the Dead Sea, there's less sodium chloride and more of other kinds of salts. WHY CAN'T YOU SINK IN THE DEAD SEA? The water of the Dead Sea is full of salt, which makes it much denser and heavier than freshwater. If you swim in it, you float very easily.
If you dive deep enough off America's northeast coast you'll find something surprising under the Atlantic Ocean: freshwater. A gigantic aquifer of mostly freshwater, hugging the coastline from New Jersey up to Massachusetts, sits below the ocean floor.
The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins. All of the world's continents could fit into the Pacific basin.
Last year an expedition to the Mariana Trench made history by conducting the deepest crewed dive ever completed as it descended 10,927 metres into the Challenger Deep.
While the recommended maximum depth for conventional scuba diving is 130 feet, technical divers may work in the range of 170 feet to 350 feet, sometimes even deeper.
If you are wanting to get colder water you'll have to head to the mountains. Snowy River, Lake Crackenback, Thredbo River and Mount Kosciuszko all have water ranging from 3 degrees to 9 degrees, with the Murray River sitting between 6 to 8 degrees during winter.
The warmest region by annual maxima is the north-west, where summers are extremely hot, but winters relatively cooler and dry.
The East Australia Current is the largest ocean current close to Australia, moving as much as 30 million cubic meters of water per second in a broad ribbon that covers as much as 100 kilometers in width and 500 meters in depth.
It is also known as the Antarctic Ocean as it surrounds Antarctica. It is the coldest and wildest ocean in the world. The Arctic Ocean is the smallest ocean in the world. It surrounds the Arctic.
Covering approximately 20 percent of the Earth's surface, the Atlantic Ocean is the second largest ocean basin in the world, following only the Pacific.
The Arctic Ocean is the smallest of the world's five ocean basins. A polar bear walks on the frozen surface of the Arctic Ocean. The freezing environment provides a home for a diverse range of creatures. With an area of about 6.1 million square miles , the Arctic Ocean is about 1.5 times as big as the United States.
On the plus side, there are no sharks or other nasties to worry about. Nothing lives in the Dead Sea except for small micro organisms.
