Seabed

However the main person credited for the founding of marine biology and oceanography was Edward Forbes, a naturalist from Britain, in 1815-1854. However, he was most recognized for his “Azoic Theory” which states, “marine organisms do not live on seabeds below 300 fathoms (1800 feet)”. This theory was very quickly disproven. In 1828, the earliest studies of plankton occurred off of the Irish coast. The first ‘modern’ oceanographic expedition was Britain’s, The Challenger Expedition. The…

The BP oil spill was a very tragic environmental disaster that occurred recently which resulted from poor engineering judgement. There were several ethical issues involved with the BP oil spill that made it such a terrible and devastating disaster. However, the disaster began with one single decision that should not have been made. The environmental ramifications that were caused by the spill are still seen along the coasts of the Gulf of Mexico. If ethical issues of the BP oil company were…

Ocean acidification is described by many scientists as a consequence of rapid increase of carbon dioxide absorbed into the ocean. As ocean acidity increases, its capacity to absorb CO2 from the atmosphere decreases. This decreases the ocean 's role in moderating climate change, "they write (Cullinane.1). As serious as this may seem several damaging effects are happening to the oceans as we speak. The most important creatures in the ocean’s ecosystem like coral are being depleted and…

Current conservation In view of the difficulties faced in conservation, different international parties held measurement to protect the Great White Shark from extinction. The CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) is the most popular international agreement in the world. It is not protecting those endangered species only, but also many wildlife species because it makes sure the sustainable development of the trade in order to safeguard the…

such as pipelines and drill cutting piles. • Toppling- this is when a minimum action is required to collapse the structure to enable it lay simply on its side at the site. • Shallow disposal- here the structure is dismantled and deposited into the seabed near the site of the operational structure. • Deep-sea disposal – this is where the removal and conveyance of the structure for dumping at a deep ocean disposal site with the possibility for there to be any additional human interaction with the…

Why are the oceans in trouble? They can no longer absorb the damage inflicted by the 7 billion people on Earth. Over many decades, the human race has overfished key species to near extinction, and polluted them with carbon dioxide emissions, toxic chemicals, garbage, and discarded plastics. A groundbreaking new study, recently published in Science, warned that our oceans are being irreparably damaged by human activity and could be on "the precipice of a major extinction event." Coral reefs,…

The two different types There are two types of eyes in the world of today. There are what one calls compound eyes and there are vertebrate eyes. Compound eyes also known as Arthropod eyes, can be traced back to an arthropod called trilobite. These ancestors didn 't have complex lenses like those of today but instead, their eyes and lenses were made of the same rock that made their skin - calcite. Compound eyes today contain many ommatidia (singular: ommatidium) which consist of a corneal lens,…

direct observations on the water column and benthic macrofauna, I will extend this record back to the last glacial maximum using geologically young fossil material (<10,000 years old), including both skeletal death assemblages accumulating in the seabed, and recently buried fossils from sedimentary cores. This longer time perspective on the Bering shelf since the Last Glacial Maximum will open the door to basic research questions related to (1) the preservation and taphonomy of fossil remains…

Harrison Showalter Dr. Shope English 1102 February 9, 2015 Cost effective Solution to Pollution The United States has done a great job over the years in reducing the output of pollution. From the series of clean air acts pasted by Congress carbon emissions fell from 197 million tons to 89 million tons in 30 years. Even though the US has one of the most regulated and strictly legislated pollution policies in the world the problem has not been eradicated. Pollution is still a growing problem but…

ice formations and melting patterns. During the spring Narwhals will penetrate receding pack-ice and in the winter they inhabit deep-water off shore. Narwhals are predators who consume pelagic fish, squid, shrimp and various bottom dwellers on the seabed. Narwhals have a distinct body shape compared to other whales. They lack a dorsal…
