The Oceans are the most diverse biomes in the world, for they cover 71% of the planet. Life in the ocean evolved 3 billion years prior than land, and it still has over ¾ of all the habitats on Earth. Humans have always posed threats to the delicate marine environment, yet it still is thriving. Without the marine biome humans and other animals alike would not be in existence, for evolution of the first life would never have occurred, and we would not have a strong enough atmosphere to support life.
The geography of the ocean varies greatly all the way from the deep Abyssal Plain, to the shallow waters of Coral Reefs. The Ocean is divided into four different zones/sub zones, the Euphotic, Bathyal, Abyssal, Hadal, and Andaphotic. These zones vary in depth from about 0 meters to 6000+ meters. The deepest point in the Ocean is about 35,000 feet deep, and it is located in the Hadal zone. The Ocean has many resources, which include, sand, gravel, manganese, petroleum, copper, iron, nickel, and cobalt.
The water depth of the Ocean varies from sea level (0ft) to about 35,000ft.
In the Ocean, the water has a certain current around land, and the current occasionally changes, based on the weather. For example, el niño affects the Ocean by the spreading of warm water from the West Pacific and the Indian Ocean to the East Pacific. The salinity of the Ocean is about 3.5%, therefore in every kilogram/litre there is 35 grams of salt. The density of seawater is approximately 1.025g/ml, and with a salinity level of 35g/L seawater freezes at approximately 28.4ºF.

The SeaWorld has been enchanting its audiences for centuries. The orcas waving hello or sticking out their tongues, getting soaked in the front row of the Shamu show, and wishing for a job like that all seemed like dreams come true at the time. In reality, these whales go through a world of physical and psychological agony to do what they do. They are torn away from their families, put in a pool that is the whale equivalent to a bathtub, and expected to perform 3 times a day, every day, nearly every day of the year. The use of animals for entertainment is immoral and should be illegal.
“The more we heat up the planet, the more it costs all of us, not just in money, but in colossal famines, displacements, deaths, and species extinctions, as well as in the loss of some of the things that make this planet a blue-green jewel, including its specialized habitats from the melting Arctic to bleaching coral reefs” (Solnit). There are many coral reefs in different oceans around the world and they are protected in different ways. Coral Reef destruction is a huge problem and while countries are conserving reefs differently, the best way to conserve them is to have marine protected areas because it allows the habitat to reconstruct itself naturally.
Since nearly the beginning of human history fishing has been an integral part of the culture and survival of coastal communities. These coastal communities and cities have always been some of the most prosperous and successful because of the added resource of the ocean. In the beginning many areas were so densely populated with fish and shellfish that often a day’s worth of food could be caught by simply wading into the shallows. For example, some of the first English settlers to see the Chesapeake Bay described “The abundance of oysters is incredible. There are whole banks of them so that the ships must avoid them. . . . They surpass those in England by far in size, indeed, they are four times as large. I often cut them in two, before I could put them into my mouth” (Miller). This abundance had every appearance of being as infinite as the ocean that produced it but the reality was far different. Many fish stocks, including the oyster, stayed near these high levels even into the beginning of the industrial era. However the new rapid pace of technological advancement proved too much for many stocks to handle. Close shore stocks took most damage as they were the easiest to exploit. Those same oyster colonies that were once an obstacle for boats were nearly eradicated by “the 1890s harvests began to decline. Many oyster beds were destroyed and reefs had been mined away. By the 1920s, the boom was over…” (Miller). While catastrophes like this inspired many sustainable practices there are still fisheries worldwide that are headed for a similar end. Through ignorance and misinformation from the fishing industry most of the general public does not know that this is occurring. The following will serve to inform about the t...
The article indicates that the influences of oceans pollution that made by humans and caused by a phenomenon called “dead zones”. First of all, there is a great amount of plastic in the ocean which causes massive consequences for animals of the entire marine food web. On the other hand, “Dead zone” also affect Earth’s oceans. “Dead zones” can formed by many causes, such as natural causes, climate change, along human activities and industrial waste. These is a national problem and humans need to have some regulatory mechanisms. Therefore, it can helps the “dead zones” reduced. The author mentions that the US Environmental
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.
Most ocean water has about 7 teaspoons of salt in 1 liter of water (sciencelearn.org.nz). The higher the concentration of salt the lower the freezing point of water. The freezing point of a substance is the temperature at which a substance usually liquid, becomes a solid. Water has a known freezing point of zero degrees Celsius.
There have been many people working to help with this issue. The majority of the activists working on this issue think that a sea sanctuary would be the best solution for the animals. A sea sanctuary is a netted-off area in a natural body of water. Most of the whales and dolphins have been living in captivity for many years and wouldn’t be able to survive in the wild anymore. A sea sanctuary would let them retire from performing, have less forced family groups, and have a more natural, peaceful environment for them to live in. The idea is that the sea sanctuaries would eventually be empty since there won’t be anymore breeding of the captive animals or capturing of wild animals. The Whale Sanctuary Project is looking for a
Ocean currents are horizontal or vertical movement of both surface and deep water throughout the world’s oceans (Briney, n.d.). The primary generating forces are wind and differences in water density caused by variations in temperature and salinity. Currents generated by these forces are modified by factors such as the depth of the water, ocean floor topography and deflection by the rotation of the Earth. Horizontal currents are wind driven, fast moving and carries small amount of water; while, vertical currents are slow moving, density driven and carries large bodies of water. In this paper I will describe horizontal and vertical currents, their importance and some of the tools used to measure ocean currents.
Oceans cover around seventy percent of the Earth’s surface. The oceans of the world have a direct relationship with weather and climate – they influence the weather both locally and globally and the changes in climate in exchange have an affect on properties of the oceans. Changes that occur to the ocean for the most part occur over a much longer period than in the atmosphere. Even if carbon dioxide emissions were to be stabilized today, it would centuries for oceans to adjust to the changes in the atmosphere. When greenhouse gases trap more energy for the sun, oceans then absorb more heat; and in turn there is a rise in sea surface temperatures as well rising sea levels. Oceans do help to reduce climate change due to the fact that they
The ocean is considered the bloodline of our planet for many different reasons; climate change impacts the oceans ecosystem which also affects marine environments, helps the world’s economy, humans depend on the ocean to sustain the earth and oceans produce half of our oxygen. The ocean plays a large role in determining the climate change. Climate change impacts the oceans ecosystem which also affects marine environments. For example, the Great Barrier reef is a victim to climate change.
Lets go ahead and take a look at what each of Earth’s biomes has to offer.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
All oceans contain salt water and other minerals. The Pacific Ocean has the largest body of water in it. It spreads nearly halfway around the world. The Pacific Ocean is also the deepest ocean out of all four oceans. The Atlantic contains the second largest body of water. Next is the Indian Ocean, which is on the borderline of being a big ocean and a small ocean. Last is the Arctic Ocean, which by all means is the smallest ocean of them all, and the shallowest.
The ocean can serve man purposes things for many different people; as a school, a home, a park...
