In the Alaskan Gold movie the fishermen and the miners were debating over weather they should leave the ecosystem for the salmon to spawn in or mine the land. This is an important economic issue because the mines could bring in a lot of money in revenue but it also could destroy the salmons spawning streams. I believe that the land should be used for mining for many reasons, but especially because it would be the largest containment of gold and copper in North America, and because of the money…

Hypothesis: Majority of male grizzly bears go fishing early in the morning while the female grizzly bears and their cubs go fishing around the evening. By the evening, most of the male grizzlies bears are all fed up and less likely to be present near the river area. Female grizzlies go looking for food during this time to protect their cubs from aggressive male grizzly bears. Design: First I will randomly pick out 15 photos from 9:00am- 11:00am and pick another set of 15 photos from 4:00pm-…

The American Submarine- it is the cornerstone of the United States clandestine and secretive military operations. While most of the military like to stay on land or the surface of the ocean, submarines like to stay hidden deep under the surface of the ocean. The priority is to make the ship sturdy and watertight. Submarines are ships that can stay underwater and also float on the surface. As you walk on the top of the submarine, you start seeing how this massive machine is built to remain…

The Gulf of Mexico is a key seafood location as is supplies the U.S 72% of their shrimp, 66% of oysters and 16% of commercial fish. With the number of sea life dropping, the seafood market with have a great economic impact on us. Prices and demands for seafood will rise considerably and many will lose their jobs. More of a long-term effect is the overall condition of the environment…

The article explains that a sea otter population in Alaska started to decline rapidly because of pollution and attack from the predators and provides three reason of support. On the other hand, the professor states that predation is the most likely cause of the sea otters to decline and refutes each of the authors reason. First, The reading states that, the infections from pollution cause the sea otters to decline in Alaska oceans. However, The professors states that, sea otters are…

Alaska was still a territory, the United States joined WW II. The government rationed food, which limited protein for the troops overseas, and citizens at home. But the U.S. had a territory loaded with fish, and commercial fishing in Alaska boomed. Thousands of fish were caught in drift-nets and fish traps. They were…

The lecturer talks about strange sounds that Russian submarine crews called quackers. She contradicts each theory of the reading, saying that they have certain problems. First, the theory that suggests that the strange noises were calls of ocra whales during a courtship ritual. The lecturer refutes this point by saying that this theory is highly unlikely, because the ocra whales lived near the surface of the ocean and the submarines cannot be able to detect in the deep ocean. So, what is state…

“The sea, once it casts its spell, holds one in its net of wonder forever,” an infamous marine biologist, Jacques-Yves Cousteau once said. He knew this spell well, enduring many dangerous marine trips in the waters surrounding his home country of France. The French-Marine explorer sailed around the world, learning about the organisms inhabiting it. This would not have been possible without his invention of scuba gear. Students study him in order to get a better understanding of marine biology.…

In trial 2 both seals and whales showed a higher rate of population. Seals are a source of food for the whale. Moreover, the higher the seal population the higher capacity of a whale. The whale is the predator to the seal, which is the prey. However, if the death rate of whales increases then, the population of seals will increase also. Only, the seal population will increase because with the decrease of whales the seals have a higher chance of living, especially with the fact that seals…

The giant squid has eluded scientist since its discovery with nothing but pictures and carcasses to go off of. Its deep-sea habitat makes it difficult to study. The first photo of a live squid was not taken until 2004 and the first live giant squid to be brought to the surface was not until 2006. The giant squid belongs to the phylum Mollusca, class Cephalopada, genus Architeuthis, and species Architeuthis dux. Giant squids are similar to their smaller relatives in many ways including, using…
