Shallow-water Acoustics and Relevant Physics By: Elizabeth Fortlage Underwater Acoustics is a complex phenomenon. Leonardo da Vinci simplified the concept in 1940‚ two years before Columbus discovered America‚ by saying “If you can cause your ship to stop and place the head of a long tube in the water and place the outer extremity to your ear‚ you will hear ships at a great distance from you.” (5‚ p.2) There are many factors that contribute to the complexity of underwater acoustics and sonar

ICE The book I chose to read is Frozen Earth: Explaining the Ice Age by R. V. Fodor‚ the associate Professor of Geology at North Carolina State University. It presents the recent discoveries and history of the ice age in an easy-understanding and accessible way. He first begins with a little background of ice ages. He then talks about glaciers and how they form and act. Then he talks about the different theories of how this happened. He concludes with speaking of the future and the climate

Effects of Erosion Jose Castro ENV/310 July 23‚ 2014 Wendy Armstrong Significance of Soil Soil is a very vital component for plants that helps them grow and thrive in the environment they are in. Erosion is causing soil to dissipate and it is putting a lot of strain on different plant species. In my paper I will discuss the effects erosion has on the environment and I will provide different ways to eradicate or control erosion. I will also discuss the consequences that erosion will provide

1. If the earth rotates in the opposite direction to that of today‚ with the aid of diagrams‚ describe the likely characteristics of the global atmospheric circulations. The sun heats the atmosphere more at the equator than it does at the poles. There would initially be a surplus of heat at the equator and a deficit at the poles which would be evenly distributed through oceans and the atmospheric circulation such as in Figure 1. This is due to the density differences between air masses because of

the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my classmates and I had field trip for Oceanography Lab (OCN 101) class with Professor Ocean Matt Horrigan. We went to Corte Madera Salt Marsh‚ which is located 12 miles North of San Francisco‚ to examine how rising and falling of tide effect on water level in the marsh and channel. My hypothesis
