Description Of Six Seawater Facts Essay

924 words - 4 pages

The Earth’s oceans salinity is always fluctuating due to a few factors. Weather is a determining factor in measuring salinity because salt does not evaporate and will remain in the ocean. Some rivers are constantly running fresh water into our ocean. Factors such as snowfall or ice melt will also have an impact on ocean salinity as it finds its way to the ocean. One interesting thing I found out was that the runoff from the Amazon is so extensive that in some places salt does not exist for up to a mile offshore. Salinity of our oceans is very important to scientific research. Awareness in the changes of salinity can date back to 300 and 600 AD. Researching and knowing facts about ocean salinity can provide information on the Earth’s water cycle and ocean circulation as well as climate. Salinity adds density to the ocean waters, which influence ocean circulation.
Why are there such major ocean temperatures around the Earth? Due to the fact that the earth is spherical, sunlight penetrates the atmosphere at various angles. In some locations such as the poles, much of the sunlight is reflected or has to pass through much more of our atmosphere before reaching the oceans. Along the equator, most oceans receive generous amounts of sunlight, which warm the water. The light that makes it through the atmosphere will then travel through the ocean waters until all of the energy has dissipated. I learned that there were 3 layers to the ocean and the temperature is pretty much constant in the Deep Bottom water no matter the depth or location. Scientists have been studying our ocean and exploring the depths for a long time now. In my research I came across a program called Argo. Argo is a program that releases profiling floats that measure temperature and salinity. Most of today’s sea surface temperature is measured by satellite. Understanding the ocean temperature can provide valuable information about Earths climate and how it has change over the years.
All marine organisms have a tolerance to certain temperatures depending on whether they are cold blooded or warm-blooded. When marine organisms are in a foreign environment with extreme temperature differences chances are they will die. Cells within an organism will adapt to the surrounding water temperatures. I thought it was interesting that animals had a much better chance of surviving in cold-water temperatures compared to warmer temperatures. Scientists have conducted experiments with marine organisms and recorded their findings as they increased or lowered water temperatures. Raising ocean temperatures will have a dramatic effect on marine life because as water temperatures increase by global warming, some species may not be able to survive. We also may not be able to relocate species to different climates if the...

Hundreds of unique species exist only at these hotspots, living on the minerals spewed by the vents. Hydrothermal vents are formed when tectonic plates move apart from one another, leaving a gap between the two. Magma then rises to the surface and heats the seawater. Were the vents at sea level, the seawater would boil immediately, but because of the immense
