Oceanography

Mô hình ROMS (Regional Oceanography Modeling System) đã được sử dụng để nghiên cứu tác động của nước biển dâng đến chế độ thủy triều dọc bờ biển Việt Nam. Mô hình được kiểm định với chế độ thủy triều hiện tại và mô phỏng với các kịch bản nước biển dâng toàn cầu là 0.5m, 0.75m và 1.0 m.

Words can easily borrow, but the meaning of love from the heart of a people is difficult to describe. So I want to ask for forgiveness from the people that support can not be appreciated in the words and from those who, by any chance, I forgot to mention. First of all what I want to thank prof. dr.ir. Wind Herman and his wife - Joke. The interviews with prof. Wind held in Bangkok and his decision has helped me to be here, at the University of Twente, to carry out my doctoral research. Herman and Joke, I will never forget...

Average depth model has a variety of applications in hydraulic engineering, especially in applications that flow depth is much smaller than the width of the flow. In this method the vertical variation is negligible and the hydraulic variables average integrated from channel bed to the surface free for the vertical axis. in equations arising management, pure hydrostatic pressure is assumed that not really valid in the case of flow in the bed is curved and can not be described curvature effects of the bed.

Autonomous underwater vehicle – a robot!Flies by changing its buoyancy – takes on water, becomes heavy and sinks – wings turn vertical motion into forward motion – expels water, becomes light and rises – flies saw tooth pattern through the ocean – from the surface to 3 m off bottom (200 m max)

An ocean wave is an undulation of the sea surface. Wave crest,Wave trough,Wave height,Wave lengt,Wave period Progressive waves move across the sea surface.,Standing waves oscillate about a fixed point. Wind velocity : Wind duration, Fetch (distance over which wind blows), Simply put, wave size increases as all these factors increase.

How does the Deep Ocean respond to Surface Circulation? The main gyres move heat and salt, Resulting DENSITY variations lead to vertical flow (sinking), Formation of“water masses”, characterized by Temperature + Salinity = Density,Density Variation in Sea Water...The densest seawater is cold and salty This is formed at high latitudes in the North and South Atlantic:

Why do objects lose their color with depth? The colors other than blue (and green) are absorbed by the water molecules in the first few meters only blue (and green) are reflected Sound is transmitted better Sound is transmitted better in water than it is in air Sound velocity in the ocean is about 1500 m/s, or about 4 times its speed in air Sound velocity increases with pressure and temperature

Where did the water in the Oceans come from? Outgassing (H2O, CO2) of the Earth from volcanoes, early in its history, but continuing today Sedimentary rocks as old as 3.8 billion years!A much smaller amount from comets that pass by.Weak electrical attraction makes for “sticky” molecules This explains its unique properties: heat capacity surface tension dissolving power

“Earth is a unique planet, possibly one of the few in the galaxy that has water. Nearly 71% of it’s surface is ocean. From space, Earth is brilliantly blue, white in places with clouds and ice, sometimes swirling with storms. At it’s surface the ocean is in constant motion with powerful currents that stretch for thousands of miles and towering waves. Beneath the ocean’s surface lie hidden mountain ranges, vast trenches tens of thousands of feet deep, immense hot springs, and huge volcanoes spewing molten rock in massive eruptions.”...
