Climate Change and the Bottlenose Dolphins - 1289 Words

Our delicate eco-system is struggling to maintain it’s complex equilibrium. The precarious state of our oceans are largely attributed to the climate changes that are on going throughout earth. Along with consistently rising global temperatures come many devastating consequences. Our atmosphere is not the only aspect of our environment that is heating. Global warming is melting polar ice caps, raising water levels in our oceans, and releasing carbon that has been trapped in ice for thousands of years. The warmer air temperature is heating the surface waters of the ocean and creating more frequent and more powerful storms. These warmer surface waters are being pushed under in the ocean conveyor belt and the overall affect is a rise in overall ocean water temperatures. Climate change has been estimated to effect 88% of cetaceans and endangering nearly 21%. More specifically, each of these changes have harmful, potentially deadly and lasting effects on Bottlenose Dolphins. Ul timately causing dangerous and toxic conditions leading to an increase of dolphin strandings and death. During the 1990s scientist were able to collect 5,000 different salinity profiles. From their findings they were able to estimate a 20 percent increase in freshwater. Due to this increase there was a rise of fresh water by 8,400 cubic kilometer, which can be compared to the volume of fresh water and ice that is released in lower latitudes from the Arctic each year.

They are killed in various manors, ranging from accidental ship strikes to the more morally controversial yearly drive hunts. As you may know nearly all cetaceans use some sort of sound production in order to navigate waters, communicate with other individuals and groups of their respective species as well as capture prey (Brownell et al., 2008). An example of this is the variety sounds produced by bottlenose dolphins (Tursiops truncatus)Read MorePollution And Warming Of The Ocean1649 Words   |  7 Pagesgases, energy leaves Earth even slower(Global Warming). This is also known as the greenhouse effect. The greenhouse effect is an increase in the average temperature of the Earth. Scientist and global leaders around the world have been pushing for change when it comes to green gasses and pollution. China is one of the worst offenders when it come to pollution. The pollution is so bad there that they have smog, where it got so bad that they have had to close schools and people now have to wear protectiveRead MoreDolphin Essay2238 Words   |  9 PagesBraided Essay: Blood dolphins and Endangered Species As my cruise ship approached the port we were about to dock at, I stood near the railing looking down into the beautiful water.

It is in the family of bottlenose dolphins, orcas, and Belugas (World Wildlife Fund). The scientific name for the Narwhal is Monodon monoceros and it is Greek meaning one-tooth, one-horn. It can grow up to 13-16 feet in length and weighs almost 2 tons (4,000 pounds). The region they are usually located is around the Arctic waters of Canada, Greenland, Norway and Russia.

Learning allows an organism to modify its behavior to suit a particular situation. It is a mechanism by which one copes with the ever-changing environment. Anything an organism does that can be measured is behavior (Chance, 2003). Organisms change their behavior to fit environmental changes; this is a learning process, it provides a means to modify our physical environment for example, changing climate by controllingRead MoreCausing Harm For Economic Growth2428 Words   |  10 Pages(â€Å"Future of the Artic†). Offshore drilling not only produces natural gases and oil, it can also be able to help find treasured metals such as cobalt and zinc that many nations rely on for new technology. The ocean is always shifting but with the climate changin g occurring around the world because of the pollution in the ocean the ice in Alaska has been receding which makes it easier to access oil and natural material (â€Å"Future of the Artic†).

The principal author of this study and chief of National Oceanic and Atmospheric Administration’s Ocean Climate Laboratory, Sydney Levitus, said, â€Å"These temperature changes may seem small, but they represent very large changes in heat content of the ocean, and this heat will eventually find it its way back to the atmosphere.† (Pawelski, 2000). Thus, although these temperature changes in the ocean seem small, they can have quite a large effect on our Earth’s atmosphere.
