Underwater Acoustics

Words: 1423 Length: 5 Pages Document Type: Essay Paper #: 49126427

Kinsler defines acoustics as the science of sound: the generation, transmission and reception of energy in the form of vibrational waves in matter. This covers a large range of disciplines and problems, including noise control, vibration and structural acoustics, and underwater acoustics. Underwater acoustics is using acoustic energy to detect objects in the oceans or sea beds - underwater - just like using radar to detect objects in the air. Acoustics systems guide underwater vessels, such as submarines, through ocean depths in the pursuit (Acoustical Society of America 2002).

We know that sound is transmitted in very long distances, even hundreds of miles, through the wave environment, which makes sound a very important tool for both commercial and military purposes. (ASA) Acoustics signals detect the presence and location of commercially useful fish, map the ocean floor to establish the safest paths for supertankers, explore the earth's geological formations and discover…… [Read More]

Ocean Water Modifies and Influences

Words: 3103 Length: 10 Pages Document Type: Essay Paper #: 16827822

The larger particles can influence the absorption rates of solar energy by a factor of three over particulates such as phytoplankton and minerals (Stramski and Woz'niak, 2005). This means that a small concentration of these particles can do a lot for the absorption rates of the water they are suspended in. The smaller particles can also have this effect, but their concentrations need to be proportionately higher to exact this same influence. The smaller particles are more influential as far as backscattering is concerned, and represent a massive shift in the way that scientists think about light diffusion and backscattering within the ocean. Previously, scientists thought that only the larger of these particles combined with other particulates were responsible for most of the solar radiation absorption (Bricaud, a., Morel, a. And Prieur, L., 1981). Now scientists understand that in shallow, mineral-rich waters, even a small presence of these tiniest of…… [Read More]

Fate of Carbon in a

Words: 4902 Length: 17 Pages Document Type: Essay Paper #: 48440011



The fact is that numerous rooted macrophyte structures are not full of naturally strong and healthy particles and sediments and nutrients. It is because of the restriction or absence of these particles, sediments and nutrients that the study of these systems has not been as extensive and thorough as the concentration on the terrestrial structures when understanding the fate, sources and sinks of Co2 levels in the ecosystems and the plants structures (e.g., Drake and Leadley 1991). Researchers assert that "rooted macrophyte systems can be sources of CO2, Chapter 4 and other gases through microbial processing of organic matter in the sediments and direct emission from leaves" (Delaune et al. 1990).

Words: 3007 Length: 11 Pages Document Type: Essay Paper #: 29018025

" Because of the ability to reproduce in large amounts in a small amount of time, phytoplankton are considered as the first link in the food chain of nearly all marine animals. Phytoplankton provide food for a large variety of organisms, including the microscopic animals (such as the zooplankton), bivalve molluscan shellfish (like mussels, oysters, scallops, and clams), and small fishes (such as anchovies and sardines). To continue the food chain, these group of animals then provide their own kind of food to other group animals like crabs, starfish, fish, marine birds, marine mammals, and humans (Karl, et al., 2001).

" (SD, 1)

McClintock goes on to connect this to pointedly negative consequences for marine life, arguing that many invertebrates are distinctly vulnerable because their protective shells require many of the nutrients naturally available in their surrounding water to maintain hardness or to develop at all. This is a concern which is also raised in the article by Monroe (2009), where the results of an experiment designed to confirm this effect were as expected. Accordingly, "[Victoria] Fabry, a biological oceanographer and visiting researcher at Scripps Institution of Oceanography at UC San Diego, studies the effects of ocean acidification on the mollusks known as pteropods. In one experiment, only 48 hours of exposure to slightly corrosive seawater caused normally smooth shells to become frayed at the edges on their way to eventual dissolution, severely diminishing their owners' chances of survival." (Monroe, 1)

This demonstrates that the increased acidification of the ocean's…… [Read More]

Speed here is of essence and spices like flying fish are able to jump out of water to escape predators. Others that lack like jellies are transparent. Turtles will have a shell to protect them. Gills enable animals to manage different water pressures like the sharks while whales have the capability of holding their breaths for longer periods. On the other hand, since the benthic zone does not allow sunlight to reach it due to its depth (beyond 600 feet), some fish and crustaceans, at this level do not see, in fact half of the species at this level are blind. In this sense, the organisms have adapted to produce their own lights from their specialized parts in their bodies known as photophores. In addition, since there is lack of phytoplacton to start the food chain, life is limited and fish have adapted to fulfill their needs. For instance, some…… [Read More]

Red Tides on the Gulf

Words: 3219 Length: 8 Pages Document Type: Essay Paper #: 19411407

brevis blooms are not a new phenomenon, and fish kills that result from red tides caused by K. brevis in the Gulf of Mexico have been described in the scientific literature since 1960 or so and have been reported anecdotally for more than two centuries (Naar et al. 2002). In this regard, Backer and her associates (2005) emphasize that, "The human health effects from consuming shellfish with high concentrations of brevetoxins in their tissues have been well documented. However, there is very little information describing human health effects from environmental exposures. It is ironic that we know the least about the aspects of the Florida red tide problem that poses the greatest public health hazard in terms of number of people affected" (645). Today, K. brevis blooms are monitored closely in order to mitigate the foregoing health hazards that are related to the consumption of shellfish and shellfish harvesting is…… [Read More]

Seafloor Sediments What Are the Different Types

Words: 630 Length: 2 Pages Document Type: Essay Paper #: 63941384

Seafloor Sediments

hat are the different types of seafloor sediments?

The three main types / categories of seafloor sediments are Terrigenous sediment, Biogenous sediment, and Hydrogenous sediments. Terrigenous sediment covers about 45% of the ocean floors, and originated from the erosion of land near the ocean's edge, from volcanic eruptions, and from dust that has blown from land to the oceans (Garrison, 2011).

Terrigenous sediments are composed of quartz sand, clays, and estuarine mud. Biogenous sediment results from the organic accumulation of materials broken down from some marine organisms. Biogenous sediment makes up about 55% of the ocean floor, and is composed of "…calcareous and siliceous oozes" (Garrison). In short, some Biogenous materials originate from corals, from the shells of mollusks (as they deteriorate their particles sink to the bottom of the oceans).

Meanwhile only about one percent of the sediment on the ocean floor is composed of hydrogenous materials,…… [Read More]

TSC: What Is eality?

We pursue virtual reality not because we seek to embrace reality, but because we seek to escape it. The availability of virtual reality technology enables us to create a controllable world which 'feels' real, but without any of the actual consequences of inhabiting reality. In virtually real games, we can act violently; become sports stars; take on entirely different personas in a consequence-free universe. One of the definitions of technology is that it technology involves the use of various created implements to make our lives seem 'easier.' To some extent, this is true of virtual reality technology, given that virtually real universes do not hold within them the risks of actually fighting, pursuing death-defying sports, or confronting supernatural beings in strange realms. However, the risks of virtual reality are great, namely that we will enter into the 'real' world after 'playtime' with a less secure grasp…… [Read More]

Sixth Grade Reading Assessment Interest

Words: 1592 Length: 5 Pages Document Type: Essay Paper #: 72375540

If anything, Jessica's apparent equating of reading speed as an indication of reading well undermines her comprehension more than technical difficulty.

Jessica understood the main idea, in general but possibility too literally: she retitled the story "What Comes Around Goes Around," and incorrectly attributed a direct cause-and- effect relationship to Leonard's charity and Riley's fate. Instead of characterizing events as an unfortunate but coincidental relationship between a genuine act of charity and an accident,

Jessica apparently assumed that Riley's misfortune might have been related to Leonard's revenge.

Summary Statement:

Jessica reads and comprehends well above her grade level. This is likely a function of her enjoyment of reading. Jessica clearly enjoys reading about subjects of interest but is comparatively easily frustrated by assigned reading outside her intrinsic interests. Jessica possesses good reading mechanics that enable her to deduce pronunciation and contextual meaning of unfamiliar words, but her ability to make…… [Read More]

Neo Pets Case Study Neopets

Life lessons, relationship lessons, even artistic, music, and performance sharing could take place (imagine, a NeoPet "Grease" production using a global cast)?

Conclusions and Implications -- NeoPets obviously provides a niche about which some consumers are excited. Like many technological entertainment devises, though, there is certainly potential for abuse. One would not necessarily want their children to sit in front of a NASCA racing program, replete with ads, for hours at a time and never have any physical activity. It is not the place of technology to mandate other behavior, but the wisdom of parents and society to create a balance. Ensuring that this will not be a fad is quite simple -- continue to evolve, to grow, to become more sophisticated in content and interaction. In a similar way, funding could come from private foundations that might sponsor a segment (e.g. Boeing on history of flight; Microsoft on computing…… [Read More]

The greenhouse effect is a condition that occurs when the Earth's atmosphere captures radiation from the Sun. Solar heat is trapped by certain gases (including carbon dioxide and methane). These gases allow sunlight in but not back out of the atmosphere. This effect can be seen on a small scale when a car parked in the sun with its windows closed heats up. Global warming is the relatively gradual increase in Earth's surface temperature that results from human activity. It has been set in motion by the greenhouse effect but is more complicated because there are feedback effects involved in climate change that magnify the initial effect of the build-up of gases such as carbon dioxide.

Global warming has the capacity -- indeed, probably the inevitable capacity -- of transforming nearly every aspect of our lives, and in most ways for the worse (Solomon etal, 2009, p. 1706).

Bowers Ridge & Shirshov Rise

Words: 1762 Length: 5 Pages Document Type: Essay Paper #: 53558396

An article in the Saturday Evening Post relates the story of a scientific party in a whaling boat on the Bering Sea in the early 20th Century "witnessed an awesome sight when, with mighty roars, fire and smoke and exploded lava shot out of the water, casting ashes and pumice all over" (Hubbard, p. 10). and, Hubbard adds, "Not infrequently huge gas bubbles hurtle upward from the ocean bottom to burst with a roar and allow the separated waters to crash back into place, sending huge geysers into the air."

Conclusion: There is much to be learned about the formation, age, and tectonic truths of ancient seafloor ridges like Bowers and Shirshov, but in this writer's opinion, the evidence points to those ridges having been formed by volcanic activity (hotspots and spreading) but at this time they are likely subduction zones.

Positive Effects of Green Energy

Green energy (such as wind, water, and solar power, as well as other sustainable options) has become a hot topic and a "buzz word" recently. Even though it may seem that everyone is talking about green energy, few people are actually doing anything about it. hile it has been seen in the news, it has not been seen in the fields and oceans where it can be harnessed and used. There are some wind turbines in use in specific states across the U.S., and there are places where water has been dammed up in order to provide electricity. Solar panels can be viewed in some places around the country, too, but there are no large scale projects currently underway to provide green energy to a significant portion of the public - and that is something that more and more people find disturbing.

CHAPTER 2: THE ORKS of JULES VERNE

Of course, Jules Verne was and remains one of the most well-known writers of fiction in the modern age. Although he was doubtlessly a gifted writer, and used a handful of literary mechanisms that were relatively innovative for his time, his enduring appeal as an author remains the fantastical subject matter of his stories. In this way, far more than any other writer from his age, Verne was a visionary. Though he failed to completely alter the primary literary conventions of the nineteenth century, he was instrumental in the invention of what has come to be the science fiction genre. Furthermore, his tales have revealed a level of foresight and scientific foresight that may never be equaled in…… [Read More]

The release of fossil fuels has been driving industrial and civic expansion for the past century and a half, and there is therefore a compelling reason to deny such causes: "some corporations whose revenues might be adversely affected by controls on carbon dioxide emissions have also alleged major uncertainties in the science (Oreskes). Just as in the debate over the heliocentric solar system, issues of political and/or economic motive are raised to cloud the science at issue.

hat truly separates the global warming debate from the issues that Galileo dealt with, however, is that there really is hard science at the base of both camps with vastly different interpretations.

Doug Macdougall's Book Why Geology

Words: 714 Length: 2 Pages Document Type: Essay Paper #: 30354188



MacDougall may point out these facts but whilst doing so he refrains from the typical alarmism that often accompanies these tracts. It is unlikely that Earth will be (as per many of the alarmists) transformed into another melting Venus, and the oceans can still absorb much of the CO2 that we are creating, although MacDougall does admit that we are destroying hordes of the marine population at the same time. He also says that our ability to release carbon emission into the atmosphere will decrease with time since our known oil deposits are rapidly dwindling.

Earth has already experienced one interglacial warming period; the extra carbon in the atmosphere aggravates the situation. Earth too is impeded form reflecting the sun's energy back into space due to the constant melting of the polar ice caps and other glaciers, thus the warming is accelerated and intensified.

Stopping Looting of Classic Greek and Roman Underwater Antiquities Sites

Cultural artifacts that both describe how a group of people lived and demonstrates the art they contrived is precious to the people who consider themselves present members of that culture or, at the very least, are residents of the nation from which the culture originated. Unfortunately, the removal and sale of these artifacts has a long history, and the trade is only recently being regulated and stopped. There are many problems with the methods used to stop the trade however and no one nation or regulatory body has been able to devise a solid means by which these treasures can be returned to the people who claim them as heritage. The heritage argument and the ability to return the artifacts becomes even more clouded when the items in question are found underwater. Although there has been a concerted…… [Read More]

Biomimicry in Product Design

Words: 1075 Length: 4 Pages Document Type: Essay Paper #: 83277867

Science

Biomimicry in Design

There is a set of trends in the 21st century regarding urban design, product design, and organizational studies. One of these trends is the act of biomimicry. Biomimicry is a design philosophy or perspective that mimics design patterns in nature. Products inspired by biomimicry are ecologically sound in design, production, and distribution processes, as well as solve human problems. Products reflecting biomimcry do not simply mimic the models, systems, processes, systems, and elements of nature for inspiration. These products mimic nature not only in design, but also in function as products of biomimicry solve problems. The design of nature avoids, anticipates, and solves problems. Thus the products inspired by nature do not mimic nature on a superficial level but on deeper levels of utility and sustainability. This paper will focus upon products that biomimic sharks. Using primary and secondary sources, the paper will evaluate the efficacy…… [Read More]

Gulf Oil Spill

Words: 742 Length: 2 Pages Document Type: Essay Paper #: 61453098

Gulf Spill

In the wake of the 2010 Gulf of Mexico oil spill, about thirty percent of the oil, and "the most volatile fraction" of it, evaporated in a period of about ten hours (Handwerk, 2011). This was the primary aerosol emanation Another ten to twenty percent evaporated over the course of the next few days, and those turned into a wide plume of aerosol that was later identified as being comprised of intermediate or semi-volatile organic compounds (Xie, 2011). This secondary aerosol was composed of both light and heavy types of hydrocarbons, which have contributed to air pollution over a wide area (Handwerk, 2011). Ironically, the pattern of aerosol evaporation from the oil spill has advanced scientific understanding of how secondary aerosols form after the initial chemical conversion from their most volatile compounds (Xie, 2011). According to the EPA (2014), in addition to volatile organic compounds, the oil spill…… [Read More]

Economic Impact of Oceans

Words: 1083 Length: 3 Pages Document Type: Essay Paper #: 66257703

Oceans on Human Life:

ecent economic, political, and environmental developments

One of the oldest forms of transport is sailing: long before airplanes or cars were invented, people turned to the sea as method of moving goods and people from one place to another. But oceans still play a critical role in the modern economy. In fact, an estimated one of every 6 jobs in the U.S. is in some way tied to the oceans and "over 1/3rd of the annual U.S. Gross National Product originates in coastal areas -- approximately $700 billion… U.S. maritime transport carries 95% of the nation's foreign trade" ("Oceans impact the economy" 2015). The importance of ocean-related shipping has increased rather than decreased in recent years, due to the rise in global trade. Although cheaper and more convenient airplane-related travel has retracted the importance of human-driven transport by sea, ocean-related trade has increased.

China Melting Ice Proper Regulations

Words: 698 Length: 2 Pages Document Type: Essay Paper #: 13054730

Therefore, to manage climate change, which is a global nightmare, regulations must be in place to limit the amount of carbon dioxide and other greenhouses gases released to atmosphere irrespective of the countries status in development.

On a different note, Spencer Richard argues in his November 17, 2008 article "Gap Between China's Rich and Poor," that countries like China, that have experienced rapid developments has left parts of the country in poor conditions. The rapid growth has widened the gap between the poor and the rich, creating even extra hurdles to the fast growing economy. ithin a span of three decades, greater percentage of Chinese citizens have benefited from the economic growth that has been export-oriented. However, the faster growth rate has led to low consumption rates both domestic and foreign.

Delta of the Guadalupe River

Words: 469 Length: 2 Pages Document Type: Essay Paper #: 10037597



Another salient feature of this delta is that it has low salinity levels when compared to other bays in the Texas region. This is because there is a great volume of water in the Guadalupe river and the adjacent bays where it empties itself is shallow. This makes it more like a freshwater delta than a saline one.

The low-salinity levels helps the growth of unique fishes that are very different from what can be seen in the other delta regions of Texas. Some endangered species found here include Malaclemys terrapin littoralis, Texas diamondback terrapin, whopping crane, white-tailed hawk and reddish egret. However, there is very little plant life in these marshes because they are in a semi-arid climate that makes it difficult for plants to grow. Instead, there are numerous different kinds of facies or sedimentary deposits that is found in different parts of this delta. These marsh sediments…… [Read More]

Delta of the Guadalupe River

Words: 781 Length: 3 Pages Document Type: Essay Paper #: 47710310



The Guadalupe River delta is found immediately across from the Guadalupe Bay site. Overall, geologists have divided this complex delta into two major parts: an older, "Old River" delta whose formation surrounded Green Lake, and a younger "Guadalupe" delta, that partly encloses Mission Bay and remains under construction. Regrettably, there is no radiocarbon estimate to accurately determine the ages of the two main deltas or that of the incorporated subdeltas. Researchers think the delta began to build upon San Antonio Bay some 2,000 years ago. Absent such radiocarbon dates for the delta proper, they must rely upon archeological finds from local digs to calculate the history of the various subdeltas.

It is generally accepted that the oldest delta (formed by the Guadalupe) first prograded to the southeast, and in later periods changed and prograded to the northeast, which isolated the upper part of San Antonio Bay, forming Green Lake. The…… [Read More]

At the American coastline, the estimated age is between 1 and 60 million years. Finally, at the borderline with the Philippine and the Australian Plates, the approximated age is somewhere between 160, up to 180, or even 200 million years.

6) the Atlantic Ocean plate is similar to that of the Pacific Ocean in the meaning that its age differs. Just like with the Pacific crust, the Atlantic crust is younger at one border, to grow older towards the middle of the ocean, and even older as it reaches the opposite border.

7) the spatial pattern of the crustal age is consistent with the theory of the plate tectonics, which argues that -- at one point in time (or even at several times) -- the entire lands on the planet were joined together (ockhounding Arkansas, 1998).

Psychometric Theory If it Exists

Words: 875 Length: 3 Pages Document Type: Essay Paper #: 8876533

The fact that at any instant in time uncountable trillions or quadrillions of individual water molecules are either entering or leaving the ocean makes the prospect of measuring the number of water molecules in the Atlantic Ocean absolutely impossible. The same observation applies to the prospect of counting every single grain of sand along the vast Atlantic Ocean shores.

However, neither Thorndike nor Ludlow would ever have argued that the Atlantic Ocean does not exist. Therefore, even at the macro level of ordinary matter (i.e. individual water molecules and grains of sand) the only defensible interpretation of the Thorndike/Ludlow expression is that it presumes the same concept as expressed by Galton. In that regard, there is no question that an unquantifiable phenomenon may indeed exist notwithstanding its defiance of measurement. the, the meaning of the phrase "If it exists, it can be measured; if it can't be measured, it doesn't…… [Read More]

Saltwater Oceans Compare and Contrast

Just as the physical properties of ocean water and lake water differ from one another in some ways but relatively similar in others, that is also the case with much of the biological life in the respective environments. On one hand, many freshwater animals (such as beaver, muskrat, mink, and otter) typically live in lakes but also spend a significant amount of time on land. Meanwhile, ocean seals and penguins spend much more time in the water by comparison. Likewise, the organisms living in the ocean tend to grow much larger than their freshwater counterparts.

On the other hand, some of the freshwater dolphin, sharks, and other lake and river-dwelling species also grow quite large. Furthermore, there is also reliable evidence that some of the largest saltwater predators such as bull sharks sometimes hunt in freshwater environments as well. Other similarities between saltwater and freshwater species are quite evident even…… [Read More]

For example, due to prevailing oceanic currents and environmental issues, a significant amount of marine debris is both generated and deposited in Korean Coastal waterways. The Korean government has removed almost 100 tons of debris in the past decade, but realizes the problem is ongoing. To reduce their own costs and improve efficiency, the Korean government incents fishermen to collect marine debris during fishing. This idea, certainly applicable to any nation with coastal waters, bot improves the efficiency of governmental collection programs, and in the long run, helps educate and compensate local fishermen (Cho, 2008).

These, and other management programs, continue to develop among the world's fishing nations. Agencies are focused on three major goals: educate young people in all countries that the world is interdependent and the oceans must be maintained for the health of the planet; educate the public, private, tourist, and fishing populations to their individual…… [Read More]

Lapita Pottery the Native Peoples

Ambrose wonders why this art form faded, and speculates that because making well-designed pottery was so "labor-intensive" that it required special tools and hence became "too burdensome to descendent settlers" who no doubt had "increasing local social priorities" (Ambrose 2003 p. 214).

Conclusion: Certainly a greater volume of information about Lapita people and their ceramic skills will be forthcoming through future research. Meantime, an interesting discovery was made in 2005, as reported in an Australian National University (ANU) media release prepared by Tim inkler. "Headless skeletons of the Lapita people…were excavated by ANU archaeologists Professor Matthew Spriggs and Dr. Stuart Bedford" (http://info.anu.edu.au).

It should not be a difficult question to answer: we must begin reducing ocean pollution and taking steps to prohibit overfishing of our ocean shallows.

The plan that is formulated to address the overfishing and man-made pollutants in the coral reefs must be conducted by authorities in marine and ecological sciences. It must be conducted on two levels: the fishing industry associated with the catches on the coral reefs; and the pollutants that are introduced into the coral reefs through contact with man. This can be done by monitoring commercial tourism and diving industries, which claim there is no residual effect on the coral reefs (Carrier, James, and McLeod, Donald, 2005, p. 315).

"

Hamilton explains that while Continental Lithosphere is as much as 93 miles thick, the "Oceanic Lithosphere" is much thinner - up to perhaps six miles. Indeed, the oceanic crust makes up only 0.099% of earth's mass, according to Hamilton. Oceanic lithosphere is a product of the volcanic magma that pushes up to force tectonic plates aside. As new oceanic lithosphere is actually formed the heat that comes up with the magma "escapes the interior as this new lithosphere emerges from below" in the Red Sea and elsewhere where there are tectonic plates spreading.

As the lithosphere cools, it contracts and then "moves away from the ridge, traveling across the seafloor to subduction zones." This process is technically called "seafloor spreading." After the lithosphere has been on the Red Sea floor for a while, it thickens up, Hamilton writes, and as it becomes even denser than the mantle just below…… [Read More]

The contribution of these discoveries to the field is significant. It could for example contribute to a greater understanding of the origin of life on earth. Scientists for example can further study the creatures discovered around the vents for the purpose of such an understanding. Further implications relate to the cycle of heat and chemicals to the seafloor and the waters overlying it. In related disciplines, it is possible that many of the large ore bodies on land are believed to have been formed as a result of these vent systems.

This relates to a long-term interdisciplinary study funded by the U.S. National Science Foundation. In addition to studying the vent system, ecosystem, and waters around the chimney, scientists are now also able to gain information relating to how earthquakes work.

Discoveries and studies such as the one described in the article prove that, vast though the body of human knowledge is, it still only scratches the surface of what is available to still discover. This serves both a humbling and encouraging function. Scientists can be humbled by the extent of what they do not yet know, as well as by the vast area of knowledge opened up by the new discovery. They are now able to study millions of years of evolution on the basis of the ocean floor structure and its vent systems. On the other hand, scientists can be encouraged for the same reasons: many new fields of discovery have been made possible both by the fact that new studies can be based upon the results, and also by the understanding that many other misconceptions may exist in other scientific fields. Furthermore, scientists can also be encouraged by the fact that many different disciplines are now involved in making the discoveries described in the article. Scientists who have never before had reasons to work together can now become teams of investigators to further knowledge and an understanding of how the world around us works.

Island nations may be beautiful, but their isolation makes them vulnerable to outside forces that increasingly threaten their survival. Rising sea levels linked to global warming could submerge some altogether. Tuvalu, a est Pacific nation whose peak height rises just 5 meters over sea level, could be uninhabitable within 50 years, some experts say. A similar fate could also doom the Maldives, the Marshall Islands, Kiribati, and Tokelau. Of all the threats facing island nations, the rise in sea level could be the most catastrophic....in the early 1990s, satellites began generating more comprehensive profiles of global sea level. Thanks to these orbiting systems, scientists now know that the average global rate of sea level rise has increased 50% during the last 12 years -- up to 3 millimeters per year from a 50-year annual average of 2 millimeters,...NASA..

The Delta is also a habitat for many species of fish, birds, mammals, and plants, and it supports agricultural and recreational activities while also being the focal point for water distribution throughout the State.

The development of the Delta as it exists today started in late 1850 when the Swamp and Overflow Land Act transferred ownership of all swamp and overflow land, including Delta marshes, from the federal government to the State of California. In 1861, the State Legislature created the Board of Swamp and Overflowed Land Commissioners to manage reclamation projects, and in 1866, the authority of the Board was transferred to county boards of supervisors. The Delta now covers 738,000 acres interlaced with hundreds of miles of waterways, with much of the land below sea level, relying on more than 1,000 miles of levees for protection against flooding. 20

Spread of Marine Larvae Predicted

Words: 620 Length: 2 Pages Document Type: Essay Paper #: 90118251

" (Science Daily, 2006) Scientists state that they suspect temperature as playing a critical role in dispersal of larvae because "metabolic processes in larvae are sensitive to temperature and similar among species." (Science Daily, 2006)

COMMENTS

Certainly, the importance of knowledge gained in this area of science has never been so critical as the life in the world's ocean is faced with change after change due to the climate changes occurring. Furthermore the understanding garnered in this study is of critical importance when considering the temperature changes that are occurring and are due to occur as the ice shelves melt and drift into the ocean current and begin cooling down the presently ocean waters that are presently experiencing higher than usual temperatures. The future of marine life is critically important in the commercial fishery industry and as well is just as important in the food-supply of those living on earth.…… [Read More]

Game animals may have been negatively impacted so that both animals and humans had to move to better areas -- most likely along the rivers and coastlines of Southwestern Europe where they could hunt and fish. Solutrean artists left evidence in rock art, which shows sea mammals, deep water fish, and great auks.

Faunal collections also show Solutreans were making use of marine resources, which were available all year round. All this would have required tool kits, waterproof clothes, nets, harpoons, and watercraft.

The authors theorize that seal would have played a large role in their lives. Probably, the Solutreans developed techniques for hunting seal during a colder period, and when the weather got warmer they would have had to travel farther out to find seals, eventually making extended trips. They came to the Atlantic Coast by following the migration of Canadian seals. Some families decided to stay. The authors…… [Read More]
