Greenland Ice Sheet Summary

774 Words4 Pages

The article that I decided to research and write about is called “Rusty Waters”, written by Rob Raiswell. This paper discusses that the Greenland Ice Sheet plays an important role in how the North Atlantic Ocean receives iron and how this iron can be utilized by phytoplankton. The scientists came up with this idea through a series of tests, observations and critical thinking. Using different samples of meltwater from glaciers in the Greenland ice sheet, they determined the amount of iron available for plankton. Next they followed the path of the meltwater and used critical thinking by considering different factors that could increase or decrease the iron content. This glacier does not empty directly into the ocean, however, it first goes into a lake and then into a fjord. This helped the scientists have more evidence on why they think iron is being transported from glaciers. In addition, they noticed that phytoplankton bloom …show more content…

This article discusses the increase in meltwater coming from the Greenland Ice sheet due to global warming and how this affects the number of nutrients that get delivered to the ocean. The scientist’s in this study accumulated four years of data which is consistent with and backs up their hypothesis. The data the scientists collected was from the Leverett Glacier which is located in the Greenland Ice Sheet. They found a strong correlation between the amount of meltwater and the number of nutrients. When meltwater increases, nutrients seem to increase as well. They believe that due to higher temperatures, there will be a higher number of nutrients because of an increase in meltwater coming from these glaciers. I chose this article because it relates to the main article I wrote. Both articles discuss the meltwater coming from glaciers and how this meltwater is important in the transport of nutrients into the

Factors That Helped The Formation Of Connecticut River Valley

499 Words | 2 Pages

Next, erosion deposited sediment into the valley, building land into it. Then, the Wisconsin glacier melted and reside north and some meltwater was collected in the lowland. This formed lake Hitchcock. Finally, water drained into the lake and headed south and then connected with the ocean. Lastly, glaciers also formed Long Island Sound.

How Did Water Shaped Michigan

1189 Words | 5 Pages

The water that was created from the glaciers melting carried out a great deal of the leftover debris, which was sorted into different sizes such as gravel or pebbles, sand, silt or clay. All of the leftovers started to form in layers or beds in river ways, ponds, and in lakes to form what the geologist call glacio-lacustrine formations. Glacio-lacustrine formations is just a scientific phrase for a glacier melted and the materials that had been inside the glacier deposit into the lakes and rivers created by the melted

Analysis Of Will Dunham's Article Melting Glaciers

376 Words | 2 Pages

The article, “Melting Glaciers blamed for subtle slowing of Earth’s Rotation,” by Will Dunham, talks about how the melting of glaciers appears to be slightly slowing down the Earth 's rotation. Also about how the melting of glaciers are due to the world 's temperatures. At the beginning of the article William Dunham states that the driving force behind the discernible change in the Earth 's rotation is measured by satellites and astronomical methods. Also that the global sea level rise is fuelled by an influx of meltwater into the oceans from glaciers. A geophysicist, Jerry Mitrovica, explained more on this problem when he said, “Because glaciers are at high latitudes, when they melt they redistribute water from these high latitudes towards

Sea-Level Rise Gives Clue To Big Chill

402 Words | 2 Pages

In the article “Sea-Level Rise Gives Clue to Big Chill” by John Roach, Roach interviews different scientists to see how freshwater impacts our oceans. Previous studies have calculated the amount of freshwater dumped into the North Atlantic based on the size of the ancient Lake Agassiz. Tornqvist and his colleagues were able to get a read on the sea-level rise associated with the 8.2 ka event by studying cores of sediment from the Mississippi River delta in Louisiana. The team retrieved two cores, one with a peat layer dated to just before the 8.2 ka event and one with a peat layer dated to just after. Renssen, the climate modeler, said the study results will help scientists in the climate research better determine the thermohaline circulation,

Arctic Compare And Contrast

397 Words | 2 Pages

Contrast between two pure white continents Many people might think that the Arctic and the Antarctica share many similarities which make these two areas alike. However, though the temperatures in these two areas are both freezing under zero Celsius and the sceneries are with icy white lands, no two regions are exactly the same on this planet. To find out more interesting factors of differences between the North Pole and the South Pole, the polar bear and the penguin will lead the way. One major and obvious difference is their geographical location.

Compare And Contrast Ocean Vs Space Exploration

Ocean V. Space Exploration The ocean covers more than 70% of the Earth, yet we’ve explored only around 5% of it. This means there is so much more to explore in the ocean. The one reason we haven’t explored as much of the ocean is because of space. Space is wildly more popular, and has proven its worth with many advancements.

Arctic Animals And Climate Change Essay

Arctic ice reflects 80 percent of the sunlight back into space. As sea ice melts there will be more sunlight hit the ocean which increase the temperature of the ocean and cause raise of sea level. Satellite observations show that Arctic sea ice concentrations have significantly decreased over the last 25 years. Submarine observations also suggest that the Arctic ice pack has thinned dramatically in the last 20 to 30 years. As the sea ice melts the sea level increase.

It is understood that the general rulings of abortion in Islam is utterly prohibited. Allah mentioned in the Qur’an, “And do not kill the soul which Allah has forbidden, except by right.” (Al-Qur’an, 17:33). This is to preserve the live of fetuses, which later become a child, as a source of challenges and sustenance to mankind in this world. Allah says, “And do not kill your children for fear of poverty.

Polar Bears And Climate Change Essay

1262 Words | 6 Pages

Earth’s climate has been changing over the last few decades, with the global temperatures rising at a high rate (Corell, 2006). Some of these climate changes are due to natural causes, although the strength at which temperatures are rising indicates human influences, such as increased carbon dioxide emission, as well as other greenhouse gases. Climate change particularly affects the Arctic region, where warmer temperatures are causing decrease in sea ice extent and thickness, permafrost thawing, coastal erosion, changes in ice sheets and shelves, and consequently, changes in the distribution and reproduction rates of Arctic species (Corell, 2006). Warmer temperatures have led to increased melting of glaciers and sea ice, and shortening of

What Is The Effect Of Pollution On Marine Life

692 Words | 3 Pages

About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
