Problem: state what could be studied after reading this article. The chemical used on ships to protect against barnacles kill the otters living on the coast of California. Research: state at least two topics that you would research on this problem Research how the TBT is killing the otters. Also what other animals eat the same shellfish as the otters to see if they also have a reaction/die from the chemical. Formal Hypothesis: state your formal hypothesis in the “If…., then…” format.
“Plastic products can be very harmful to marine life in the gyre. For instance, loggerhead sea turtles often mistake plastic bags for jellyfish” (Great Pacific Garbage Patch). This littering needs to stop! We are killing the marines out in the middle of the ocean, and have no absolute control over their natural diet. No animal can swim thru the Great Pacific Garbage Patch; it has too much trash, the trash tends to sink to the bottom of the ocean and the animals can get caught into a plastic rings.
Tiger sharks actually eat whatever they can find. This is where they get the nickname “waste basket of the sea”. (http://www.sharkinfo.ch/SI4_99e/gcuvier.html) They consume fish, turtles, dolphins and other sharks, they are man eaters. Tiger sharks eat about two to three percent of their own body weight per day to cover their energy requirements. These sharks have a very great sense of smell and sight.
There are about 35 different species of seahorses all over the world. They are unique majestic sea creatures related to sea dragons, pipe fishes, and pipe horses. Interesting deep sea fish that are used for multiple medical cures, food, and aquarium beauty. Seahorses are becoming extinct because of over fishing and habitat destruction. This will cause them to die off because of lack of food if we are not careful.
“Whale Wars” is a show about a conservation society who protects whales in the southern ocean from the Japanese Whaling Fleet who hunts whales to sell the meat illegally on the Japanese Market. The Fin Whale is located worldwide from the North Pacific to the Southern Pacific to the Indian, Mediterranean and the Arctic Oceans as well as the Southern Antarctic (WWF, 2007). The Pelagic Zone is where the Fin Whale lives and is a coastal species sometimes living in shallow waters(WWF, 2007). It feeds through the baleen plates in taking large amounts water filtering it through its mouth to in take fish, krill and squid(Harrison, 2005). When it feeds on schools of fish it often lunges sideways in taking the school within several lunges.
Whale populations dwindled, so whalers looked towards rorquals (baleen whales), but they swam too fast to be caught by rowed boats and they sank when they died. The development of the harpoon cannon allowed a way so rorquals could be killed consistently. Norwegians refined this technology and developed a way of keeping the whales afloat by injecting compressed air into them (McNeill). The profit from hunting these whales was mainly from the whale oil; the oil from the rorquals could be made into margarine and into soap. A by-product of boiling the whale blubber into oil was “glycerin, needed for nitroglycerin which is used in dynamite,” so with the arms
This report will contain global issues, including the worryingly named “Great Pacific Garbage Patch”, oil spills and local problems, such as the previous near destruction of the Port Noarlunga reef, which, prior to the establishment of the South Australia’s first aquatic reserve, had been overfished and polluted. Although the ocean covers approximately two thirds of the Earth’s surface, it is surprisingly susceptible to human influences. The effects of rubbish dumping and chemical run-off have tainted our oceans and they have taken their toll on the vast marine environments and the populations in which they contain. Circulating the Pacific Ocean is a gyre of marine debris (Non-biodegradable human waste that has collected in marine environments), worryingly named “The Great Pacific Garbage Patch”. Such an entity had been theorised and predicted by oceanographers and climatologists, however, it was discovered by yacht captain, Charles Moore.
The object of the trip is to look for a monster that has been attacking other ships. After a few months out into open water, they are attacked, by something that looks like a monster. After, the so called monster got hit by cannonballs and a harpoon the crew noticed that water came out of his wounds instead of water. The force of this water throws the scientist, along with Conseil, and a famous whale killer Ned Land into the sea. Eventually they get close to the monster, which eventually turned out to be a shark-shaped submarine, called the Nautilus.
A Fight Against Dolphins and Whales in Captivity “The greatness of a nation and its moral progress can be determined by the way it treats its animals” - Mohandas Gandhi Whales and dolphins have recently become a topic of conversation after the death to Dawn Branchaeu, a forty-year-old marine mammal trainer who was killed by a whale during a show at Sea World. What made this majestic animal turn on its trainer? The answer is simple. This whale, like many others, was ripped from it family at a young age, put in a concrete tank and forced to do tricks for food. The conditions in which whales and dolphins are living in captivity are inhumane and unjust.
The Consequences of Overfishing Overfishing has been identified across the world as a prominent environmental issue. Fish and other marine animals, such as sharks, sea turtles and dolphin, are retrieved from the oceans through indiscriminate fishing practices at a rate that cannot be sustained by natural reproduction (Jackson, 2001). Systematic overfishing with bottom trawling, dredges, and drift nets depletes the ocean of innumerable species at an alarming rate and alters the ecological balance in marine environments. The actions of shortsighted commercial fishermen have brought tremendous adverse environmental and economic consequences upon the entire world. The continuation of unrestricted fishing will worsen world hunger among impoverished coastal communities, many of whom depend on the abundance of fish to feed themselves and their families, and result in ultimate environmental chaos and the extinction of thousands of In recent years, the demand for fish, a healthy food rich in omega-3 fatty acids and lean protein, has sky-rocketed.
