the southeastern Pacific, Murray and Renard (1891) did not recognize the anomalous nature of the sediment. Instead, credit for the discovery of the metallic nature of this sediment lies with Boström and Peterson (1966), as results from their experiment displayed a marked enrichment of Fe, Mn, Cu, Cr, Pb and Ni in sediments from the East Pacific Rise. Metal-rich sediments have since been recovered from a number of from a number of sites, most prominently on the East Pacific Rise and Mid-Atlantic Ridge
Typically, the level of ocean water around the world is higher in the western Pacific and lower in the eastern, near the Western coast of South and North America. This is due primarily to the presence of easterly winds in the Pacific, which drag the surface water westward and raise the thermocline relatively all the way up to the surface in the east and dampen it in the west. During El Nino conditions, however, the easterlies move east, reducing the continuing interaction between wind and sea, allowing the

between the ocean and atmosphere in the east central equatorial pacific. El Nino is the warming of the ocean surface. According to NOAA, during this time frame rainfall over Indonesia reduces while rainfall increases over the tropical Pacific Ocean. The combination of El Nino and the Southern Oscillation is the year to year changes in sea surface temperatures, rainfall, surface air pressure and atmospheric circulation that happen over the equatorial Pacific Ocean. El Nino and La Nina are opposite
of the Earth's plates. 5. Find the Nazca plate and the South American plate. How are they different? Are they moving toward or away from each other? The Nazca plate is an oceanic plate, while South American plate is continental. The Nazca is moving East towards the South American plate at a downward angle and converging. This process is called subduction, resulting in a lot of earthquakes and production of the Andes Mountains. 6. List the kinds of features you might expect to see near the edges
connected the East Coast to West Coast. The tracks were 1,776 miles long, laid west of the Mississippi River. America was connected coast to coast for the first time. Construction started on May 10, 1860, and ended six years late at Promontory Summit, Utah. Before the construction even started the planning of the railroad began way early. Surveying the ground began in the early 1850’s. The first train in America started running the early 1830’s. And by the end of 1840’s the entire east coast was laid
The Railroad Boom The main reason for the transcontinental railroads to be built was to bring the east and west together. The building of these railroads caused huge economic growth throughout the United States. The railroad created opportunities for everyone across the US. "Railroads were the first big business, the first magnet for the great financial markets, and the first industry to develop a large-scale management bureaucracy. The railroads opened the western half of the nation to economic
ocean and of the sky to navigate them to this new land. They faced the unknown and braved into the wide-open ocean for long periods of time. The real focus in this paper is on the navigation techniques that they used in these voyages throughout the Pacific. It's impossible to teach someone the significance or the act of loving the stars and the ocean but that's what makes navigation without instruments (wayfinding) so beautiful. One can "give the heavens a meaning his own meaning" says Nainoa Thompson
In the article, El Niño: Pacific wind and Current Changes Bring warm, Wild Weather by Mike Carlowicz and Stephanie Schollaert Uz they study the patterns and event changes that happens in one place and can affect life half a world away with a sudden change to the ecosystem. It is able to make half a world have wetter season and another be dryer than the dessert. This article talks about some fundamental observations, human history, and the impact and teleconnections that El niño has caused on today's
Ocean and Climate The ocean and its massive flow of water or currents are vital to how the heat energy moves between the Earth’s bodies of water, landforms and atmosphere. The ocean is a crucial factor in the storage and transfer of heat energy across the earth. The movement of heat through the ocean currents affects the regulation of weather conditions and temperature extremes. The global climate is directly impacted by the ocean’s current. “The ocean covers more than 71 percent of the Earth’s
specific weather occurrence in the Pacific Ocean can have an effect on every day life in the United States. El Nino is one of the largest scientific phenomenons that scientists have ever explored. The main concepts of El Nino are very simple and there are many variations, causes, affects, and relationships to study. The main idea behind El Nino is that the wind changes direction across the Pacific Ocean. In a non El Nino year (normal), the trade winds blow from east to west across the ocean, from
seeking a new warm water port in the Yellow sea both for their navy and to expand their ability to trade in the Pacific. At the time, Russia's only reliable naval hub in the region was Vladivostok, which was only in operations during the summer months The A to Z of the Russo-Japanese War. . Russia's main reason for a port in the Pacific was to fortify and consolidate its hold on the Pacific region The A to Z of the Russo-Japanese War. . Port Arthur was a key asset to the empire, but Russia's poor
and Taiwan is starts to curve upwards and it is then diverted. The new current from that point is known as the Kuroshio current. The Kuroshio current is a North Eastern flowing current. The current flows past Japan and Nansei Shoto then flow’s more east back towards the North American continent. The is a part of the Kuroshio current known as the Tsushima current which is a current that flows between the Tsushima strait between Korea and Japan. The Kuroshio current is a warm current due to the fact
melting hundred times faster than anytime in history. Causing sea levels to rise between 7 and 23 inches by the end of the century. While global temperatures continue to rise the ocean will get warmer impacting sea life. For example, squid and tuna have migrated up to the Northern Pacific because water here in Southern California are not as cold as they use to be to keep them alive. Salmon is about to be affected if northern Pacific if water continues to get warmer. Over the years researchers have seen
INTRODUCTION In 1835 Charles Darwin, aboard the vessel HMS Beagle, first set foot on the Islands of the Galapagos Archipeligo setting off on what would become the inspiration for the most important innovation in biological sciences either before or since. That visit solidified for Darwin his notion of the evolution of life on Earth, and helped trigger his breakthrough regarding Natural Selection, ultimately culminating in his groundbreaking masterpiece On the Origin of Species by Means of Natural
Mercury - surface geology Mercury is a very gray planet, which houses no living creatures or any ‘life’ in General. Mercury's surface is covered in impact craters, basaltic rock and smooth plains, many of them caused by what they believe is flood volcanism. Other features include vents which seem to be the cause of magma-carved valleys, often-grouped irregular-shaped, termed "hollows" that are believed to be the cause of collapsed magma chambers throughout the planet. The biggest crater on mercury
A volcano is a mountain or hill, which has a vent where lava, broken pieces of rock, hot vapor, and gases are being erupted from beneath the Earth’s crust. It is unknown where the first volcano was located; however, the first one recorded was Mount Vesuvius in Naples, Italy. The ash and rock from that particular eruption engulfed Pompeii, making it hard to breath. Eventually, the ash was turned to mud from the rainfall, which soon buried it. It was said that some people were able to successfully
2.0 Introduction The currency exchange rate gives a great influence to the development of a country. The tourism, consumption and human resources are the three most obvious sectors that affected by currency exchange rate. The Malaysian Ringgit (MYR) to Singapore Dollar (SDG) exchange rate is drop year by year since 1980. This issues give impact to Malaysia especially Johor state, since Johor is just a strait far from Singapore. In this chapter, the information about the currency exchange rate
India-Australia relations have seen a steady growth from 1991 to 2016 despite various disagreements that have risen between the two nations. At the core, both nations are strong, vibrant, secular and multicultural democracies in the Indo-Pacific region. The convergences between India and Australia have increased as the years have gone by, while the divergences have contracted. This is different from how the two countries viewed each other during the Cold War period, where India saw Australia as a
The Eastern Highlands The Eastern Highlands are scattered highlands that extend along the east coast of South America. They rise sharply along the coast and slope gently towards the Central Lowlands. South America has three major highlands – the Guiana Highlands, the Brazilian Highlands and the Patagonian Plateau. • The Guiana Highlands are located in the northern parts of the Central Lowlands. They lie in between the Amazon and Orinoco Rivers. The Guiana Highlands are spread across the Southern
