1. Adaptation is a noun. Also a change or the process of change of that an organism can best suit the environment lived in. A: Desert, Its hot and very dry.…
• Hudson Bay receives more river runoff per unit area or volume than the Arctic and other world’s oceans, with potentially larger effects on circulation and vertical mixing, and light distribution in the euphotic zone • Several studies have concluded on the efficacy of using CDOM as a tracer of runoff due to its conservative nature . Also suspended solids can also act as a tracer of runoff • CDOM plays a significant role in the upper ocean heat budget and in the carbon content of the upper ocean in the Hudson Bay, also in supply of nutrients to the bay (Granskog et al., 2007; Guégen et al., 201; Pegau, 2002) • Convergent suspended sediment plume in the estuary results in the development of the estuarine turbidity maxima (ETM) aided by…
The extremely low climate and low biodiversity are the most known. Most of the energy and nutrients found in tundra are in the form of dead organic matter. The arctic tundra is found in the northern hemisphere, but much of it extends south. The tundra can be looked at as a type of cold desert. The growing season mostly ranges between 50 to 60 days, which is a relatively short…
The biome that I picked was the Arctic Tundra. The animal from Arctic Tundra I picked is the polar bear. Female polar bears would rather build their den in old snow,( like from a few years ago.) The polar bear is found in Canada , the U.S (Alaska), Greenland, Russia Norway (the Svalbard archipelago), and Arctic Tundra.…
The mean winter temperature is -34° C. The arctic tundra is able to support life because in the summer the mean temperature is 3-12° C. The arctic tundra can have fewer amounts of precipitation than large numbers of deserts even though the arctic tundra’s land is moist or wet with plentiful ponds and lakes. This is because of the low temperatures in the arctic tundra. The low amount of evaporation adds to the creation of…
Arctic Tundra Wide variety of plants (1,700 kinds of plants) Short growing season (50 – 60 Days) Carbon Sink (Stored in permafrost) Animals adapted to long winters …
The Arctic Tundra is the youngest biome in the world- it formed only 10,000 years ago. When the snow melts, The Tundra has marshes, bogs, and lakes. It is very windy here, the winds blow between 30-60 miles per hour. The predators of the Tundra are wolves, polar bears, wolverines, and arctic foxes. There are only 1,700 species of plants in this area- which is not very much.…
In the article “Hot Spots in a Freezing Ocean Offer lessons in Climate Change” talks about how climate change can affect the animals in Antarctica. Gail V. Ashton, a marine ecologist, and his colleagues predicted that in 50 years the Southern ocean will increase temperatures by 1.8 degrees Fahrenheit and in a 100 years the ocean will gain 3.6 degree Fahrenheit. In June 2015, Ashton started an experiment to determine what will happen to the aquatic animals if we heated the ocean. First, Ashton’s team was able to place three panels underwater, on the coast of Antarctica. Each panel was able to increase the temperature of the water by 1.8 degrees Fahrenheit.…
The four basic cultural divisions of the Arctic consisted of the Unangan, Yup’ik, and 2 types of Inuit. The Arctic is a very harsh environment, so these tribes had to learn to live with the cold, and have strong self-reliance, cooperation, modesty, self-control, and share with others. The Unangan lived in large, permanent communities located on the Aleutian Islands. This was a relatively warm environment.…
Wheat crops also drown the nutrients especially if planted repeatedly year after year. Once the soil nutrients could no longer support the crops, the wind and drought took…
Decapitated, dismembered, hung bodies. Sounds like a horror movie right? Close, but no, these are just the remains of Celtic bog people These people were either religious sacrifices, punishment or just a simple murder cover-up. These bogs were the epitome of the mummification of bodies. These people were the unfortunate ones who found themselves in that situation, but offer us a new insight on the life of the ancient Celts.…
The summers last only about two months and the temperatures are still very cold from 3 to 12 C.The Tundra is a type of biome where the tree growth is hindered by low temperatures and short seasons. The term Tundra comes from Russian from the Kildin tundar during the “uplands”,”treeless mountain tract”. The Tundra is the biome that has cold temperatures even summer,but lots of wildflowers grow and sprout during that period. The Tundra is 3 million square miles long and covers 20% of the earth’s surface.…
One type of sediment to note is diatomaceous earth, an uplifted siliceous ooze which contains the remains of the microscopic algae known as diatoms (Garrison and Ellis 152). With a density lower than most other sediments—measured at 0.2816 g/ml in our lab results—the powdery and apparently sticky sediment has rather tiny grains as expected from this sort of sediment. As diatomaceous earth derives from the diatom ooze of the deep ocean floor, it originates from the slow dissolution of diatom remains along with their high productivity in some surface waters, both of which build up the ooze (149). Another sediment to note is coral sand, which comprises of coral bits and foraminiferan/other calcareous remains (“Coral”). Having the highest density…
According to the 2014 Arctic Report Card, there have been significant changes in sea ice extent. Specifically, the report addresses the slow but significant seasonal decline in sea ice cover. Arctic sea ice is of utmost importance for ecosystems to thrive. Post et al. (2013) discuss this further, stating “the sea-ice biome influences the abundance, distribution, seasonality, and interactions of marine and terrestrial species.”…
Sediments and solids flush more frequently into freshwater bodies along with phosphorus and nitrogen as a result of heavier precipitation, and when these solids wash into rivers and lakes, they reduce the penetration of light and suffocate bottom-dwelling organism ("Environmental Assessment 4.0" 12). In this way, plant growth is limited, and organisms feeding off those plants become susceptible to starvation as competition for food increases. Consequentially, fishery production will suffer. Without healthy freshwater ecosystems, societies around these lakes and rivers could lose a…
