Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and environment and biology is the study of the animal itself.Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world. At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms contribute significantly to the oxygen cycle, and are involved in the regulation of the Earth's climate.[1] Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land.[2]Marine biology covers a great deal, from the microscopic, including most zooplankton and phytoplankton to the huge cetaceans (whales) which reach up to a reported 48 meters (125 feet) in length.The habitats studied by marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the abyssal trenches, sometimes 10,000 meters or more beneath the surface of the ocean. It studies habitats such as coral reefs, kelp forests, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic) zone, where solid objects are rare and the surface of the water is the only visible boundary.A large amount of all life on Earth exists in the oceans. Exactly how large the proportion is unknown, since many ocean species are still to be discovered. While the oceans comprise about 71% of the Earth's surface, due to their depth they encompass about 300 times the habitable volume of the terrestrial habitats on Earth.Many species are economically important to humans, including food fish. It is also becoming understood that the well-being of marine organisms and other organisms are linked in very fundamental ways. The human body of knowledge regarding the relationship between life in the sea and important cycles is rapidly growing, with new discoveries being made nearly every day. These cycles include those of matter (such as the carbon cycle) and of air (such as Earth's respiration, and movement of energy through ecosystems including the ocean). Large areas beneath the ocean surface still remain effectively unexplored.。

海洋即“海”和“洋”的總稱。地球的四分之三的面積被海洋覆蓋?？偯娣e大約為3億5525萬5千平方公里。一般人們將這些占地球很大面積的咸水水域稱為“洋”，大陸邊緣的水域被稱為“海”。少數(shù)地球以外的星體也有海洋，一些尚有海洋或冰洋，如衛(wèi)星土衛(wèi)六、木衛(wèi)二，一些行星如火星、金星曾經(jīng)可能有過海洋或火漿洋。

因?yàn)楹Ｑ竺娣e遠(yuǎn)遠(yuǎn)大于陸地面積，故有人將地球稱為“大水球”。四大洋在環(huán)繞南極大陸的水域即南極海（又稱南部海{Southern Ocean}）大片相連。傳統(tǒng)上，南極海也被分為三部分，分別隸屬三大洋。將南極海的相應(yīng)部分包含在內(nèi)，太平洋、大西洋和印度洋分別占地球海水總面積的46%、24%和20%。重要的邊緣海多分布于北半球，它們部分為大陸或島嶼包圍。最大的是北冰洋及其近海、亞洲的地中海（介于澳大利亞與東南亞之間）、加勒比海及其附近水域、地中海（歐洲）、白令海、鄂霍次克海、黃海、東海和日本海。

小水滴與大海

很久很久以前，在一戶村莊的小溪里有著一顆晶瑩可愛小水滴，他夢(mèng)想著、盼望著想要流入大海，變成大海里的一份子。但小水滴的母親小溪卻不同意讓小水滴流入大海。

這天，小水滴問它的母親小溪：“媽媽為什么大海會(huì)永不干涸呢？”小溪媽媽回答它：“孩子你要知道，浩瀚的大海也是由無數(shù)水滴組成的，有你、還有你的許許多多的伙伴，如果沒有了你們，也就沒有了大海。這就叫‘不積小流，無以成江海?！毙∷温犕旰螅胍谌氪蠛５臎Q心更強(qiáng)了。

春天過去了，取而代之的是酷熱的夏日，熱日炎炎，岸邊的花枯萎了，田里的莊稼渴死了，小溪媽媽的身體也漸漸縮小了。小溪媽媽對(duì)著小水滴說：“好孩子，你去大海里吧，那里永不干涸。你首先要繞過前面那幾座高山，再進(jìn)入一條江，穿過湖那邊的那座橋，才能到達(dá)大海，但是你要記住，即使在路上有懸崖當(dāng)?shù)溃呐聫膽已律系粝?，摔得粉身碎骨，也要想盡一切辦法再重新匯聚起來，流向大海。再見了，孩子，祝你一路順利！”小水滴向媽媽揮揮手就出發(fā)了。

小水滴經(jīng)過千辛萬苦終于來到了大海。小水滴開心地從東跑到西。玩兒累了，就躺在大海老人的懷抱里進(jìn)入甜甜的夢(mèng)鄉(xiāng)。在夢(mèng)鄉(xiāng)里小水滴開心的笑了。

4.英語作文海洋小故事

PollutionSea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.I need to describe the problem. Our ship currently dumps all its rubbish into the sea.It's easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly. A case in point is that we should stop providing plastic bags.We must act now before it is too late！海洋污染英語作文二：Reduce Sea PollutionSeveral problems are caused by the non-organic substance. We ought not to pour wastes into the ocean, because it not only pollutes the ocean, but also lead to a series of harmful consequence. First and foremost, the non-organnic things, for instance, plastic bags, may kill fish and whales. Second, fishes can't digest them. Finally, some of the rubbish is inherently toxic, they will posion marine life.We must take actions to protect our whale from dying. One thing we should do is creating a better system of disposing of rubbish. Another effective solution is making ships environmentally friendly. Sypermarkets shall stop the giving of plastic bags.As a captain of the ship, you should spare no efforts to think more helpful ideas and stop dumping rubbish from now on. We all need to raise awareness of these problems. It now becomes necessary that we must act now, before it is too late！海洋污染英語作文三：Sea pollutionBetween 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. Around 12% of the pollution is caused by maritime transport.In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2003, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2006.Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water。

), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides。) and agricultural waste (fertilisers, pesticides。

).This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.海洋污染英語作文四：Sea PollutionMarine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the world's 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,Marine living resources are likely to cause more damage.The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habit。

5.急需十條關(guān)于海洋的小知識(shí)

1.人們常喜歡用藍(lán)色來形容海洋。其實(shí)海水的顏色，從深藍(lán)到碧綠，從微黃到棕紅，甚至還有白色的，黑色的，并非只是藍(lán)色。

海水和普通水一樣，都是無色透明的，海洋色彩是由海水的光學(xué)性質(zhì)和海水中所含的懸浮物質(zhì)、海水的深度、云層的特點(diǎn)及其他因素決定的。大家知道，太陽光由紅、橙、黃、綠、青、藍(lán)、紫七種顏色組成，這七種顏色的光，波長各不相同，從紅光到紫光，波長逐漸變短，長波的穿透能力最強(qiáng)，最容易被水分子吸收，短波的穿透能力弱，容易發(fā)生反射和散射。海水對(duì)不同波長的光的吸收、反射和散射的程度也不同。光波較長的紅光、橙光、黃光，射人海水后，隨海洋深度的增加逐漸被吸收了。一般說來，在水深超過100米的海洋里，這三種波長的光大部分能被海水吸收，并且還能提高海水的溫度。而波長較短的藍(lán)光和紫光遇到較純凈的海水分子時(shí)就會(huì)發(fā)生強(qiáng)烈的散射和反射，于是人們所見到的海洋就呈現(xiàn)一片蔚藍(lán)色或深藍(lán)色了。近岸的海水因懸浮物質(zhì)增多，顆粒較大，對(duì)綠光吸收較弱，散射較強(qiáng)，所以多呈淺藍(lán)色或綠色。

紫光的波長最短，反射最強(qiáng)烈，為什么海水不呈紫色呢？科學(xué)實(shí)驗(yàn)證明，原來人的眼睛是有一定偏見的，人的眼睛對(duì)紫光的感受能力很弱，所以對(duì)海水反射的紫色很不敏感，因此視而不見，相反，人的眼睛對(duì)藍(lán)、綠光卻比較敏感。

另外，由于太陽時(shí)而隱沒在云層之中，時(shí)而透過云層放出光芒，海洋的顏色也就隨之發(fā)生變化。海洋的顏色還取決于太陽離地平線的高度。
