Navy Sonar Testing Vs. Marine Life

Sonar is an artificial form of echolocation, which involves the use of sound navigation and ranging techniques for the propagation of sound underwater. This technology is used for navigating, communicating or detecting objects that are under or above the water surface. Specialized sea creatures such as whales and dolphins have the ability to use sound reflected from waves for sensing and locating distant objects or prey, this is called echolocation. Bats also use the same technique to navigate in the dark. Humans also use echolocation through sonar technology in ships and submarines to avoid icebergs, locate ...

Introduction

Simply put, sonar is the use of an echo. This involves the use of sound navigation and ranging techniques for the propagation of sound underwater, with the overall intention of navigating, communicating or detecting objects that are in or on water surface. Specialized machines and sea creatures such as whales have the ability to use reflect waves for sensing shape and movement of objects and for locating these distant objects. Because there are different ranges of frequencies for sonar, there are low-frequency, mid-frequency and high-frequency sonar. Like any other use of technology or technological enhancement, sonar testing has its ...

Have we ever contemplated of how our society would be like without litter? We tend to throw any piece of trash at our disposal on the ground not thinking that, that small piece of trash finds other trash which later on builds up into piles of junk. Littering has become common in many cities around the world and if not stopped, our environment will be negatively affected by our own actions. I choose to write an argument on littering in public places, especially in our school because, it has become an environmental hazard and it is affecting our environment. ...

INTRODUCTION

The research capitalizes on the condition of coastal marine environment due to eutrophication (Gray, Shiu-sun Wu and Or). This process of enrichment that is suppose to foster growth to marine and aquatic life is believed to have an adverse effect due to the disturbance that it creates in the marine system. According to the authors, eutrophication facilitates for excessive nutrient absorption of most aquatic plants and microorganism. As a result, it increases the rate of sedimentation that results to hypoxia. When this happens, fishes and other marine life forms do not receive sufficient oxygen. Malabsorption of oxygen stags growth. ...

` The movie outlines the causes of ocean acidification as simple and easy to remedy in the following outline. Ocean acidification occurs because of burning fossil fuels in the atmosphere. The carbon dioxide released from these fuels is dissolved in the ocean water forming carbonic acid. The beginning of the industrial revolution saw an increase in industries burning fossil fuels and subsequently led to an increase of carbon dioxide released into the air. The process involved in the acidification of the ocean is a chemical one where, as carbon dioxide is dissolved in the ocean water, it reacts with the ...

Food security remains one of the challenges facing the world today. Nations across the globe have embraced mechanized agriculture, which encourage use of synthetic fertilizers, reclamation of wetlands, and use of chemicals thus interfering with soil fertility, marine life, ground water, and estuarine environments. Synthetic fertilizers contain high levels of nutrients such as nitrogen, calcium, ammonia, phosphate, phosphorus, and magnesium, which increase crop yields and maturity. However, prolonged use of synthetic fertilizers has detrimental effects on the environment as it alters nitrogen cycle and facilitates accumulation of nitrogen compounds in water, soil, and atmosphere. Large amount of nitrogen in ...

Introduction

Although the world’s oceans cover about two thirds of the entire earth’s surface, it is usually very vulnerable to the influences of human beings that include pollution, overfishing and human activity waste dumping. This pollution usually has significant effects on the economy and also has a lot of health impacts particularly on the marine life because it kills the marine animals and also destroys their habitats and ecosystems. The toxins from fertilizers and pesticides used in farms usually contaminate the nearby rivers that eventually flow into the oceans and thus cause extensive marine life loss. The dumping ...

Introduction

Marine pollution takes place when potentially harmful or harmful particles, chemicals, waste, or invasive organisms get into the ocean. Most sources of marine pollution are based on the land. Marine pollution usually comes from nonpoint sources dust, windblown debris, and agricultural runoff. Marine pollution can also result from nutrient pollution where excess nutrients is put into the sea. The result of this excess nutrient such as phosphorus and nitrogen stimulate the growth of algae which cause eutrophication on the surface of the sea (Birni & Boyle, 1994). Marine pollution causes presence of toxic particles into the sea. These toxic particles ...

Introduction

Our knowledge of ocean life is limited to big fishes and salty water. However, with new discoveries it is now evident that ocean life is mainly kept in balance by microorganisms. Billions of micro, nano and singular celled organisms called planktons are the primary producers of the marine fish web. Any living being in order to survive needs energy in the form of food and on earth the sole supplier of energy is the Sun. Be it ocean food chain or terrestrial food chain it always start with the sun. In case of terrestrial chains plants and weeds are ...

Abstract

Different physical and ecological events along the Gulf of Mexico allows the toxic phytoplankton – red algae to become dominant. The phosphorus-rich nutrient supply encourages phytoplankton succession. The objective of the paper is to study the background of red algae, and why the downstream red tides have only increased over the last couple of decades. The toxic red tides are seen in similar coastal habitats of the western boundary currents China, New Zealand, Japan, and South Africa.

The Galapagos Island: Darwin’s Description

The Galapagos Island is a cluster of volcanic islands situated in the Pacific Ocean. Charles Darwin explored the island after discovering local animal inhabitants. Darwin described the island as fields made up of basaltic lava. According to Darwin, the ground had various cracks or crevices, which led him to describe the island as ‘broken’. At first, Darwin believed the island was uninhabited due to limited vegetation but as he explored the island, he discovered its rich biodiversity (Nagle, 1999). The Galapagos Islands are “famed for their rich biodiversity and unique species of iguana, sharks, blue and red-footed boobies, penguins, ...

Marine life is core of marine biology where a study on taxonomy, biology, behavior, morphology, and ecological relationships of life inhabiting our oceans, seas, and lakes is on research. It is also the study of science of organisms in marine or ocean waters. Taxonomy of marine life is in groups that follow a certain order in a hierarchical series namely: kingdom, phylum, class, order, family, genus, and species. Marine life is having six kingdoms as follows. First, bacteria-are organisms that have single-cells and reproduce by dividing in two. They are throughout the marine setting. Second, protozoans-are also single-celled organisms ...

The term pollution in the simplest and most basic meaning refers to the condition, situation and circumstance where harmful and toxic materials and substances find their way to the environment thereby making human life inhabitable and unhealthy.

There are many types of pollution that drove the World to be in critical situation. Not only the developed countries are responsible about this issue, but also the developing countries are more pinpointed since they have low standards and criteria to keep the environment healthier. One of these types is seas pollution. Often the ability of water to cleanse itself is already inadequate to cope with the ever increasing number of pollution. “A great deal of water pollution happens not from one single source but from many different scattered sources” (Woodford). Fields of pollution generated mainly in the coastal ...

The Great Pacific Garbage Patch

Section: Introduction The growing concern of the world to global warming can be traced back to pollution. One of the most apparent is water pollution which affects three-fourths of the whole world. The ocean is where most of the human waste, be it intentional or unconsciously, goes. This waste is called marine debris. It does not only include human waste, but also the natural waste occurring in the environment which escalates as the degradation of the bodies of water continues. According to (U.S. Environmental Protection Agency, 2011), marine debris is any persistent solid material that is dumped into the ...

Biodiversity and sustainability, two of the major factors to determine if an ecosystem is habitable and sufficient for any life form, may it be fauna, fawn or human kind. However, there are only a few sites left around the globe which can be considered sustainable and contains biodiversity as climate change continues to affect the planet. Some areas have become barren, while a few remained arable but in the risk of being converted into commercial lands for homes or businesses. In the United States, the problem of pollution not only affected its once diverse ecosystem, which is considered the ...

The Southern Oscillation Index (SOI)

Ausloos and Ivanova (2001, p. 1) succinctly define the Southern Oscillation Index (SOI) as a core component or characteristic of the El Nino phenomenon. The SOI data have been collected and analyzed since the year 1866 so as to effectively study and explain the occurrence of extreme climactic events. This makes it possible for meteorologists to understand the outstanding factors of the sometimes catastrophic phenomenon of El Nino and therefore be able to estimate and accurately predict future trends.

In essence, the core aspects of the SOI are derived from studying the cyclical warming and cooling of localized regions ...

In her article, “BP’s Deep Secrets”, Julia Whitty investigates precisely the outcomes of the oil spill on a long term, focusing mostly on the Gulf ecosystem and following how are the flora and fauna from this area are affected by this catastrophe. The current essay, based on Julia Whitty’s article will be supported by other sources that have treated this ...

The endangered basking sharks

Richard & Charles (2000) define an endangered species as one that may become extinct if measures are not taken to avert the situation. Endangered species have a small population and are often affected by human or natural environmental changes leading to their demise and eventual extinction. Sharks as an endangered species have in the recent past elicited reactions from animal conservationists, who have staged demonstrations against the intrusion of human life activities that have led to the decline of the different species of sharks. Richard & Charles (2000) note that sharks reproduce in small numbers thus putting them in great vulnerability ...

The 1982 Draft Convention of the Law of the Sea is a set of rules that governs the use of global oceans, the airspace, the seabed, and the subsoil below. It aims at balancing the interests of nations in controlling activities off their own coats and the nations’ interests in protecting their liberty to uses the waters without interference. The Convention addresses several issues such as exploitation and conservation of ocean resources, navigation and overflight of the oceans, marine scientific research, and protection of the marine environment (The United Nations, 2011).

The Bush Administration asked for this law to ...

The Goals Of Sustainability are as follows:

- The common greenhouse gases which affect the global climate are carbon dioxide, water vapor, methane, nitrous oxide, hydrofluorocarbons, perfluocarbons and sulfur hexafluoride. The appropriate amounts of these gases are required for maintaining the right temperature in the environment for the existence of life. However, if there are no gases the temperature would drop to 0°C or even below and if there is too much of these gases the temperature would become very hot. So a balance between the gases is necessary for the existence of normal life on the earth. Normally, all the greenhouse gases are transparent which ...

In Partial Fulfilment of the Requirements in

Introduction The characteristics or features of islands, especially small islands or Small Island Developing States (SIDS), are such that the local economy in these territories or regions would depend on tourism unlike larger states (Briguglio & Briguglio n.d., 1). We can attribute this to the prevalence of tourist-related activities, specifically people choosing to visit SIDS for vacations or holidays. As argued by Jack Carlsen (2012), islands are appealing tourist locations because of the images that these territories engender. The desire of people to separate themselves from fast-paced, contemporary life influence them to view islands as idyllic spots for holidays where ...

Introduction

This case study concerns a dilemma faced by the environmental compliance manager of a plastics manufacturer, reference the amount of toxins discharged in the factory’s wastewater released into an adjacent lake. Although the levels are within current limits, failure to introduce new (expensive) technology to reduce the levels further could not only make the lake’s fish unsafe for human consumption, and cause the imposition of future regulatory constraints on the company, but could damage the company’s profitability.

Firstly, the environmental compliance manager Jonica Gunson has to consider all the affected stakeholders in this scenario. In terms ...

Introduction

In its natural state, Carbon dioxide (CO2) is a colorless and odorless gas. Its significance in preserving life on Earth is demonstrated through Carbon cycle, a process that begins with the use of CO2 by plants for photosynthesis and ends with the release of the same compound into the atmosphere by the dead and decomposed plants and the animals that feed on them. This cycle is continuous and ensures that the supply of Carbon (a vital element of life) is sufficient. This paper, however, focuses on the disastrous effects of excessive CO2, released into the environment.

The effects of public smoking cause to the community and the environment should be properly analyzed using available data and further research to support the proposal that Public ...

A reality that has been always considered a hoax by many as they believe global warming is because of the changing nature of the Universe and how the planet rotates. Global Warming is real because while it could be naturally influenced, the concentrations of the greenhouse effect emmissions causes the rays of the Sun to remain on earth, further influencing climate. The dispute that rages over this issue is unresolved because “experts” have shown “proofs” (for and against) based on scientific data. Supporters of the non-existence of Global Warming, basically offer the arguments as that the climate has changed ...

Many scientists argue that oceanic acidification, which is said to arise from dissolving of artificial carbon dioxide emissions, has serious impacts to both the land and sea life. Besides, scientists equate oceanic acidification to the evils of global warming. However, in this essay, we argue that oceanic acidification does not pose much threat to either land or sea life, and it should not be such a significant environmental concern. Oceanic acidification, from artificial carbon dioxide emissions, is said to cause a decrease in PH level of the ocean, thus interfering with marine life. However, I refute this point because ...
