About Sea

Not to be confused with Ocean or World Ocean

List of seas

The sea is the interconnected system of all the Earth's oceanic waters, including the Atlantic, Pacific, Indian, Southern and Arctic Oceans.

However, the word "sea" can also be used for many specific, much smaller bodies of seawater, such as the North Sea or the Red Sea.There is no sharp distinction between seas and oceans, though generally seas are smaller, and are often partly (as marginal seas) or wholly (as inland seas) bordered by land.

However, the Sargasso Sea has no coastline and lies within a circular current, the North Atlantic Gyre.

The sea, the world ocean, or simply the ocean is the connected body of salty water that covers about 71% of Earth's surface (361,132,000 square kilometres [139,434,000 sq mi]), with a total volume of roughly 1,332,000,000 cubic kilometres [320,000,000 cu mi].It moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. It has been travelled and explored since ancient times, while the scientific study of the sea—oceanography—dates broadly from the voyages of Captain James Cook to explore the Pacific Ocean between 1768 and 1779.

Waves

Tsunami

A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea.

Tides

Tides are the regular rise and fall in water level experienced by seas and oceans in response to the gravitational influences of the Moon and the Sun, and the effects of the Earth's rotation.

The Earth is composed of a magnetic central core, a mostly liquid mantle and a hard rigid outer shell (or lithosphere), which is composed of the Earth's rocky crust and the deeper mostly solid outer layer of the mantle.
The zone where land meets sea is known as the coast and the part between the lowest spring tides and the upper limit reached by splashing waves is the shore.
Over most of geologic time, the sea level has been higher than it is today.
The sea plays a part in the water or hydrological cycle, in which water evaporates from the ocean, travels through the atmosphere as vapour, condenses, falls as rain or snow, thereby sustaining life on land, and largely returns to the sea.
Oceans contain the greatest quantity of actively cycled carbon in the world and are second only to the lithosphere in the amount of carbon they store.

Animals and other marine life

There is a broader spectrum of higher animal taxa in the sea than on land, many marine species have yet to be discovered and the number known to science is expanding annually.

Time spent in self-reflection is never wasted – it is an intimate date with yourself

Self-reflection and Introspection, two processes which started to grow ever more important in the past few months of my lifeWith all the hustle and bustle usually filling our everyday lives and minds we often forget to pay attention.

Ray Chin

The first photographer in Taiwan to photograph whales and dolphins underwater.

As a soldier in the university, he took the initiative to get to know the Kuroshio Ocean Culture and Education Foundation,and then became a full-time underwater photographer and entered the world of whales and dolphins.
