Canaries of the Sea

The white whales, or beluga, are residents of the arctic seas of the world. The common name is Russian, which comes from the adjective belii, meaning, “white”. Beluga whales have adapted to their life among sea ice, which is why they are all white in color and may grow up to eighteen feet in length (Haley, 1978). Belugas are gregarious and graceful and are enjoyed by everyone who meets them. Beluga whales are the only whales that can bend at the neck without moving their whole body. Different from other whales, they don’t have a dorsal fin but just a ridge on their back, which helps them trap the heat and stay warm in their icy Arctic surroundings. Belugas will migrate south to avoid getting trapped in the ice whenever the Arctic water freezes in the colder months. Belugas are mostly seen in large schools with a male leading the group. The schools may even get up to hundreds or thousands in numbers during migration (Tryckare, 1968). …show more content…
Echolocation is the production of sound waves that are then followed by echoes, which aid cetaceans to locate objects and explore their surrounding environment. Many of the cetaceans feed in the murky waters where vision is of little use so the ability to echolocate has evolved. Echolocation is extremely quick and efficient since the sound waves in water travel 1,500 meters per second, which is over four times faster than it is in air (Rothenberg 2008). A single beluga can produce signals with high frequencies of 100 to 120 kHz (Rothenberg, 2008). The sound waves produced bounce off the objects under water that return to the beluga in the form of an

Truth Behind the Legend: Atlantis

...of the most popular legends of all time. Its story dates back to around 420 BC maybe even before then. It was first told about by a philosopher by the name of Plato in his Critias and Timaeus dialogues, the first recorded references to Atlantis. (Atlantis – Lost Civilization) Plato claimed that Atlantis was a huge island in the Atlantic Ocean the size of North Africa. (Atlantis, the Antediluvian World, by Ignatius Donnelly, [1882]) He told of the people and that they were unusually educated and technologically advanced far greater than other cultures at the time. (Summary of the legend) According to Plato the result of a massive flood possibly bought on by a Earthquake or submarine volcanic explosion caused the great city to sink below the sea.(Summary of the legend) Now for thousands of years people have been debating whether Plato’s “lost city” was fact or fiction. Many Scientist such as Professor Charles H. Hapgood, of Keene State College at the University of New Hampshire believe that there could have been a lost city like the one Plato states even if they don’t believe in certain parts of...

Eurotunnel

...Intel, Eurotunnel and many others have a lot of individual projects to implement in the organisation with limited resources. The process of managing this group of on-going, interdependent, related projects in a coordinated way to achieve strategic objectives can thus be called Programme management. Programme management has become a very important discipline because it enables the sharing of resources across projects and provides a guide for the engagement of senior managers. Many organisations tend to fail or have issues with managing the organisational programmes as a result of issues such as risk management, quality management and resource management. The mandate of this paper is to talk about the Eurotunnel and Crossrail programmes, their impacts, major issues identified with the projects/programmes. This paper also identifies some of the key lessons learnt from the Eurotunnel and finally justifies why...

Tenerife

...Safety August 24, 2012 Abstract To err is human, or at least that’s how the saying goes. Most mistakes that people make are small, but then there are those mistakes that can be life threatening. On March 27, 1977, two Boeing 747 passenger aircraft collided on the runway of Los Rodeos Airport, on the island of Tenerife, in the Canary Islands. A combination of factors contributed to the collision, but the end result fell on human factors. Due to several instances of miscommunication, misunderstandings, over-confidence, and lack of patience, the lives of 583 people were taken. This paper discusses what actually happened, and utilizes information gathered from the Netherlands Investigation Board, the research and input discussed by ALPA (Air Line Pilots Association), and human factors that were involved. Human Factors and the Tenerife Airport Disaster To err is human, or at least that’s how the saying goes. Most mistakes that people make are small, but then there are those mistakes that can be life threatening. On March 27, 1977, two Boeing 747 passenger aircraft collided on the runway of Los Rodeos Airport, on the island of Tenerife, in the Canary Islands. A combination of factors contributed to the collision, but the end result fell on human factors. When it comes to human error, specifically in the aviation field, situational awareness is the key. The weather conditions, in conjunction with the unusual parking conditions at the smaller airport, were only two of the major...

Man Versus Nature: Technology Versus Environment: Money Versus Wild Life

...Man versus Nature: Technology Versus Environment: Money Versus Wild Life Bristol Bay Although the fishing industry has long been associated with the contribution of marine pollution little work has been done on the effects on the industry itself of marine debris and other pollution. The fishing industry is responsible for discarded nets, hooks, fishing poles, and many times sunken boats, among other gear. In many circumstances this is not the intended plan when going fishing to catch their paychecks. In fact the fishing industry pays a high price for these losses from the time they have to replace their nets to the pulling of old nets and trash out of their new nets on a regular basis. When questioned about the effects of marine debris on their fishing activities, Shetland fishermen responded that 92% had recurring problems with accumulated debris in nets, 69% had had their catch contaminated by debris and 92% had snagged their nets on debris on the seabed. Many also experienced fouled propellers and blocked intake pipes. On average, 1-2 hours per week were spent clearing debris from nets. Debris could cause a restricted catch and many boats avoided particular fishing areas altogether due to the high concentrations of debris. It has gotten to the point for many fishers that they can no longer fish certain areas known to be well stocked with money fish due to the time consuming issues with trash and fishing debris in those specific waters due to left behind gear.

...DEFINITION FROM WIKI (understand and write it yourself) In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbanceby resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation and the introduction of exotic plant or animal species. Disturbances of sufficient magnitudeor duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates.Human activities that adversely affect ecosystem resilience such as reduction of biodiversity, exploitation of natural resources,pollution, land-use, and anthropogenic climate change are increasingly causing regime shifts in ecosystems, often to less desirable and degraded conditions. Interdisciplinary discourse on resilience now includes consideration of the interactions of humans and ecosystems via socio-ecological systems, and the need for shift from the maximum sustainable yield paradigm to environmental management which aims to build ecological resilience through "resilience analysis, adaptive resource management, and adaptive governance". The concept of resilience in ecological systems was first introduced by the Canadian ecologist C.S. Holling  in order to describe the persistence of natural systems in the face of changes in ecosystem variables...

Global Warming

...GLOBAL WARMING: Energy, Fall 2005 v30 i4 p36(2) It could get a lot warmer. (GLOBAL WARMING) Full Text: COPYRIGHT 2005 Business Communications Company, Inc. If humans continue to use fossil fuels in a business as usual manner for the next few centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar to 14.5 degrees warmer than current day. These are the stunning results of climate and carbon cycle model simulations conducted by scientists at Lawrence Livermore National Laboratory. By using a coupled climate and carbon cycle model to look at global climate and carbon cycle changes, the scientists found that the earth would warm by 8 degrees Celsius (14.5 degrees Fahrenheit) if humans use the entire planet's available fossil fuels by the year 2300. The jump in temperature would have alarming consequences for the polar ice caps and the ocean, said lead author Govindasamy Bala of the Laboratory's Energy and Environment Directorate. In the polar regions alone, the temperature would spike more than 20 degrees Celsius, forcing the land in the region to change from ice and tundra to boreal forests. "The temperature estimate is actually conservative because the model didn't take into consideration changing land use such as deforestation and build-out of cities into outlying wilderness areas," Bala said. Today's level of atmospheric carbon dioxide is 380 parts per million (ppm). By the year 2300, the model...

Efficiency Analysis of Container Port Terminals

... container ports and their terminals. The structure of the shipping market is, moreover, continuously evolving. On the carrier side, shipping companies form consortia and alliances; on the port side, global terminal operators and dedicated container terminals are emerging. The aim of this research is to evaluate the efficiency of container ports and terminals and to study how to improve the scale efficiency of any particular port/terminal. In particular we study how certain factors influence the efficiency of container ports and terminals. Regional container ports and global container terminals are examined based on the econometrics benchmarking method Stochastic Frontier Analysis (SFA). Two datasets are used, a panel dataset for 32 container ports in the North Mediterranean Sea over a nine-year period, and a cross-sectional dataset for 165 container terminals worldwide. Net-effect and gross-effect SFA models are applied to both datasets. Technical, scale and overall efficiencies of individual ports/terminals are evaluated. Operation and investment strategies are examined for selected ports and terminals. The majority of the container ports and terminals in our North Mediterranean Sea samples are found to...

Globalization

...However, elsewhere – including possibly India – the sovereign state is often still struggling to retain its monopoly control. In doing so, the state stifles the full potential role of cities to advance the world, to reduce the burden of world poverty. Liberating the cities is thus a key part of the agenda for the new century and for the eradication of poverty. NIGEL HARRIS I Introduction his paper seeks to present a view of the era of globalisation through highlighting particular changes which mark the break with the preceding period, the heyday of the nationstate. The exercise is undertaken in order to assess the resulting radical changes in the conception of spatial planning and thus the emergence of a new agenda for the management of cities. Following the introduction, the second part seeks to clarify what might be meant by ‘globalisation’, and the third, the main features of the management of the old order. The fourth concerns the transition from one to the other, and the fifth, the emerging new agenda. The penultimate part concerns the emergence of a city of services, and the paper concludes with a discussion of some of the issues concerned with the governance of the new order. T II What Is ‘Globalisation’? Over the past two decades, the term ‘globalisation’ has become...
