Is video me hum mahasagaron ke tapaman ke baare me janenge ki kis prakar se mahasagaron ke taapmaan me pariwartan hota hai aur kaun kaun se factor use effect karte hain. Oceanography Playlist https://goo.gl/CfAowt Temperature is a physical properties of Ocean water. Ocean Temperature is affected by following reasons 1- Sun light 2- Density of water 3- Salinity 4- Vaporization and condensation 5- Ocean Current # The average temperature of Ocean is 3 to 4 degree Celsius but the temperature of its surface is 25*C # The temperature of Ocean going to decrease from Equator to pole. #The temperature of Ocean water is maximum in August while it's minimum in February. #Going From top to bottom the temperature of Ocean water going to decrease . #The Ocean which will connected with more landmasses having high temperature in comparison to the ocean connected with less landmasses at same latitude . The temperature of the ocean determines what form the water takes. Most of the ocean is liquid water, but if it gets cold enough, it turns to solid ice, or if it gets hot enough, it can pass into the atmosphere as water vapour Water warms up more slowly than air but can hold more heat – water needs 4 times as much energy to raise its temperature by 1ºC as the same mass of air does – so the ocean plays an important part in taking up energy from the Sun and stopping the Earth getting too hot. Variation in temperature The temperature of the ocean, especially the surface, varies from place to place and from season to season. Ocean temperature depends on the amount of solar energy absorbed. Tropical oceans receive a lot of direct overhead sunlight for much of the year, so the water is warm. Summer is the only time polar regions receive sunlight, and even then, it is never directly overhead, so water in these places tends to be cold. The amount of sunlight that hits the temperate regions (between the tropics and the poles) varies between summer and winter. The variation in solar energy absorbed means that the ocean surface can vary in temperature from a warm 30°C in the tropics to a very cold -2°C near the poles. The temperature of the ocean also varies from top to bottom, giving a vertical structure to most of the ocean. There is an upper layer of water, up to 200m deep, that is warmed by the Sun and has the same temperature from top to bottom. Below that is a layer called the thermocline, reaching down in places to 1000m, which is colder at the bottom than at the top. The deep ocean below the thermocline, making up 80% of the ocean, is the same very cold temperature throughout. What happens when temperature changes Some properties of water change with temperature: Cold water is denser than warm water, so it tends to sink. Cold water holds more dissolvable gases, such as carbon dioxide Water temperature can affect the productivity of organisms living in it. Water expands when it warms up – heat energy makes its molecules move around more and take up more space. Because the molecules are more spread out, the density goes down. When water cools, it contracts and becomes denser. Temperature and salinity both affect the density of water, resulting in water moving up or down through the ocean layers and moving as currents around the ocean.

Fresh Water Meets Sea Water – Boundary Explained
This is the Fraser River Delta just in front of Vancouver BC Canada, this is where sea water meets fresh water. The river water from Fraser River, flowing into the ocean water of the Strait of Georgia. Modern Science has discovered that in the places where two different bodies meet, there is a barrier between them. This barrier creates a noticeable line, as each water body has its own temperature, salinity, and density. If you go on google earth and look up Fraser River or Sea Island which is an airport right at the water edge, you will see this boundary line stretching for miles.

NASA | The Ocean: A Driving Force for Weather and Climate
The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable. This animation helps to convey the importance of Earth's oceanic processes as one component of Earth's interrelated systems. This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites to measure physical oceanography parameters such as ocean currents, ocean winds, sea surface height and sea surface temperature. These measurements, in combination with atmospheric measurements such as surface air temperature, precipitation and clouds can help scientists understand the ocean's impact on weather and climate and what this means for life here on Earth. NASA satellites and their unique view from space are helping to unveil the vast... and largely unexplored.... OCEAN. NASA Earth Observing System Data and Information Systems (EOSDIS) EOSDIS is a distributed system of twelve data centers and science investigator processing systems. EOSDIS processes, archives, and distributes data from Earth observing satellites, field campaigns, airborne sensors, and related Earth science programs. These data enable the study of Earth from space to advance scientific understanding.

Sea-level rise
Although it may not be immediately obvious when we visit the beach, sea-level rise is affecting coastlines all over the world. For low-lying countries such as the Netherlands, sea-level rise and tidal surges are a constant threat. Our oceans are rising as a consequence of climate change. As the temperature of seawater increases it expands and the ice melting from ice sheets and glaciers adds more water to the global ocean. We know this because satellites high above our heads measure the temperature of the sea surface and of our changing ice. While the global averaged trend is towards rising levels, there are many regional differences so that in some places it is rising and in other places it is falling. Satellites carrying altimeter instruments systematically measure the height of the sea surface so that sea-level rise can be closely monitored. Altimetry measurements over the last 25 years show that on average sea-level is rising about 3 mm a year and this rise is accelerating. ★ Subscribe: http://bit.ly/ESAsubscribe Check out our full video catalog: http://bit.ly/SpaceInVideos Follow ESA on Twitter: http://bit.ly/ESAonTwitter On Facebook: http://bit.ly/ESAonFacebook On Instagram: http://bit.ly/ESAonInstagram On Flickr: http://bit.ly/ESAonFlickr ESA is Europe's gateway to space.

How Seawater Desalination Works
CASE STUDY: Desalination is a complicated process, the Seven Seas Corp.* approached DaVinci Studio to develop an animation that simplified the explanation of the process. Taking a cue from Seven Seas we started with squiggly style animation to give the technical looking components a non-technical look. Bottom line is to go from engineering-speak to the layman's level. Desalination (also called "desalinization" and "desalting") is the process of removing dissolved salts from water, thus producing fresh water from seawater or brackish water. Desalting technologies can be used for many applications. The most prevalent use is to produce potable water from saline water for domestic or municipal purposes.

What If Ocean Water Lost Its Salt
Lots of people on certain parts of continents don’t have access to fresh water from rivers or lakes, and this crisis is getting more and more serious each year. Every 7th person on the planet suffers from a lack of access to clean drinkable water right now. And some experts say that as the world population doubles by 2030, that statistic will skyrocket to one-half! Actually, 97% of all the water on the planet has always been briny, and you can safely assume that it’s this way for a reason. …So magically pushing a button to make it fresh water in this hypothetical situation would be devastating for life on this planet. And here's why. Other videos you might like: What If Megalodon Sharks Didn't Go Extinct? https://www.youtube.com/watch?v=Xh6pVbaEJTw& What If You Were the Last Person on Earth https://www.youtube.com/watch?v=7uGAINMAiL0& What If You Poured Some Water On The Sun? https://www.youtube.com/watch?v=0GOPAxEBDro TIMESTAMPS: Why the ocean is salty 1:44 Was seawater originally fresh? 3:08 Food chains would be destroyed 4:15 How the climate would change 5:36 Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY: - Rivers constantly bring fresh water to the oceans. You’d think these sources would dilute the sea and decrease the salt content. But in fact, it’s quite the opposite. Water in rivers is also brackish – it’s just 70 times less salty than in the ocean. - Each year 4 billion tons of salt are carried into the ocean just from rivers alone. If you keep doing that for the billions of years this planet has been in existence, you can imagine how much salt would gather there. - Sea salt derives from a hydrochloric acid, while river salts are from carbonic acid. More scientists today believe that the oceans have been salty from the start because of volcanic activity. - The most obvious consequence is that the innumerable forms of marine life can only exist in briny water – they wouldn’t survive in fresh water. - Without them, we’d lose this source of food, which would have a serious impact on not only the countries that are highly dependent on their fishery sectors, but also those they export to! - Like animals, algae are capable of feeding on organic material in their environment. Like plants, they take part in photosynthesis. They play a huge role in sustaining life because of this. - Ocean currents make the climate on earth a lot more tolerable and suitable for living. Take salt from the oceans, and the currents will disappear. Salt water has a much lower freezing temperature too. Without the salt, bigger parts of the oceans would turn to ice during the winter. - Plus, all that salt would eventually start appearing right back in the oceans! Minerals from the Earth’s crust would start dissolving into the sea again, and oceanic floor vents would also pump minerals into the water.

What Happens When You  Mix Salt Water and Ice?
Not a "Lipton" ad The freezing point of pure water is 0°C, but that melting point can be depressed by the adding of a solvent such as a salt. The use of ordinary salt (sodium chloride, NaCl) on icy roads in the winter helps to melt the ice from the roads by lowering the melting point of the ice. A solution typically has a measurably lower melting point than the pure solvent. The following figures were found in a published report, but have not been checked out in detail. A 10% salt solution was said to lower the melting point to -6°C (20°F) and a 20% salt solution was said to lower it to -16°C (2°F). A pleasant application of the freezing point depression is in the making of homemade ice cream. The ice cream mix is put into a metal container which is surrounded by crushed ice. Then salt is put on the ice to lower its melting point. The melting of the solution tends to lower the equilibrium temperature of the ice/water solution to the melting point of the solution. This gives a temperature gradient across the metal container into the saltwater-ice solution which is lower than 0°C. The heat transfer out of the ice cream mix allows it to freeze. http://hyperphysics.phy-astr.gsu.edu/hbase/Chemical/meltpt.html Salt: https://www.amazon.com/Morton-Iodized-Salt-26-Ounce/dp/B015FDIPSU/ref=sr_1_3_a_it?ie=UTF8&qid=1501533482&sr=8-3&keywords=salt

Sea surface temperature - Video Learning - WizScience.com
"Sea surface temperature" is the water temperature close to the ocean's surface. The exact meaning of "surface" varies according to the measurement method used, but it is between 1 mm and 20 m below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass. Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth's oceans. Tropical cyclones can also cause a cool wake, due to turbulent mixing of the upper 30 m of the ocean. SST changes diurnally, like the air above it, but to a lesser degree due to its higher specific heat. There is less SST variation on breezy days than on calm days. In addition, ocean currents such as the Atlantic Multidecadal Oscillation , can effect SST's on multi-decadal time scales, a major impact results from the global thermohaline circulation, which affects average SST significantly throughout most of the world's oceans. Coastal SSTs can cause offshore winds to generate upwelling, which can significantly cool or warm nearby landmasses, but shallower waters over a continental shelf are often warmer. Onshore winds can cause a considerable warm-up even in areas where upwelling is fairly constant, such as the northwest coast of South America. Its values are important within numerical weather prediction as the SST influences the atmosphere above, such as in the formation of sea breezes and sea fog. It is also used to calibrate measurements from weather satellites. Wiz Science™ is "the" learning channel for children and all ages.

17: Sea Surface Temperature
One of the amazing properties of water on Earth is that water has the highest heat capacity of just about any natural substance known. It takes months for the Atlantic waters to absorb the intense tropical sunlight, but during the process an amazing amount of energy is stored in the water. This energy makes its way into tropical storm clouds when water evaporates from the ocean surface. Water molecules are in essence "mobile solar collectors" that transfer the ocean's energy into clouds, where the energy can then power a hurricane.

Thermal Expansion of Water: Demonstration and Explanation
Many substances expand when heated (e.g air or metal). Water also expands when heated (note that the thermal expansion of water only begins above four degrees Celsius). To demonstrate the thermal expansion of water a 750mL plastic bottle is filled with water and a drop of blue food coloring. A straw is put through the bottle cap and sealed so there are no leaks. The level of water in the straw is measured and then a lamp with a 100 watt bulb is turned on and directed at the bottle. Measurements of the water level are taken for two hours to show the thermal expansion of water. When the light is turned off, the water cools and contracts, returning to its original position. The thermal expansion of water is one of the primary causes (along with ice melt) of the rising sea levels on earth. As the global average temperature increases the water in the oceans expands occupying more volume. This leads to sea level rise.

Make a freezing mixture by adding salt to water | Water | Physics
Adding salt to water reduces its freezing point, making it possible to lower the temperature of water below its normal freezing point without turning it to ice. This activity compares the behaviour of ice in regular water and salt water and shows that ice melts at a slower rate in salt water. Before refrigeration, such freezing mixtures were once a big industry used for cooling, food preparation and transport. Even today, freezing mixtures remain useful for small scale operations or in areas where electricity is not available.

Nano Lagoon (10): Temp and Salinity
http://www.ipsf.com We discuss salinity, specific gravity and temperature maintenance in the Nano Lagoon reef aquarium. Salinity Salinity and specific gravity are related measures of how "salty" the seawater is. We use a simple plastic hydrometer to measure these levels. Our Instant Ocean Hydrometer cost about $9.00 at Wal-Mart. We begin by filling the hydrometer with tap water, and using a pencil or stiff wire to carefully knock any air bubbles off the indicator arm. The salinity should read "0" and the specific gravity should read "1.00." Next, we discard the tap water and fill the hydrometer with seawater from our Nano Lagoon. The salinity should be about 33 ppt (parts per thousand). Specific gravity should be about 1.024 units. If we are careful to keep the seawater level constant in our Nano Lagoon with daily additions of tap water as needed, the salinity will not vary much and can essentially be ignored. Nevertheless we should check this parameter twice a month with the hydrometer, just to be sure. If the salinity and specific gravity get too low, it means that the seawater in our Nano Lagoon is not salty enough. In that case we use seawater (instead of tap water) for our daily additions of makeup water, checking each day with the hyrometer until the salinity is back to 33 ppt. Temperature We use the digital stick-on thermometer to determine the temperature of the seawater. If you find the thermometer hard to read try briefly shining a flashlight on it. Ideally the temperature in the tank should be about 75 degrees Farenheit. An acceptable range of temperatures is about 70-80 degrees for the hardy species in your Nano Lagoon reef tank. We recommend keeping the tank at "room temperature" as long as it is not too hot or cold for prolonged periods. This way we can avoid using an in-tank heater. It's one less thing to buy and worry about. If the temperature in your house regularly falls below about 68 degrees Farenheit, then a small (25-50 watt) aquarium heater might be necessary. Please use only captive-bred organisms in your reef aquarium.

How to Determine the Density of Salt Water
Watch more Intermediate Math Skills videos: http://www.howcast.com/videos/316202-How-to-Determine-the-Density-of-Salt-Water The density of salt water depends on how much salt is dissolved in it. Calculate the density of a particular sample with the method described here. Step 1: Fill a bottle with tap water Weigh an empty 1-liter bottle on an electronic balance, and then fill it with room temperature tap water. Step 2: Weigh the bottle Weigh the filled bottle on the balance. Then subtract the weight of the empty bottle and note the weight of the tap water. Tip The balance should have a capacity of at least 1.5 kilograms and be accurate to within 0.001 kilograms. Step 3: Weight the bottle with salt water Replace the tap water in the bottle with room temperature saltwater, and weigh it. Then subtract the weight of the empty bottle and record the weight of the saltwater. Step 4: Calculate the weight ratio Calculate the ratio of the weight of the saltwater-filled bottle with to that of the tap water-filled bottle. Step 5: Calculate the saltwater density Multiply the ratio by the density of pure water –1000 grams per liter – to get the density of the saltwater in grams per liter. Did You Know? Bathers float on the Dead Sea in Israel because the salt water density is so high.

Salt Water Swimming Pools - Myths & Truths you Need to Know
WEBSITE: http://www.swimmingpoollearning.com/ YouTube Video Index -- A list of all of my videos: http://poolmandave.blogspot.com/2014/03/swimming-pool-tips-reviews-how-to-video.html In this video I dispel some commonly held Myths about a salt Water Pool. Often referred to as Salt Water Generators. There are several videos on YouTube on this subject so I decided to weigh in myself. One-third of my pool route -- roughly 35 pools are Salt Water Pools. So I have lots of practical real world experience with salt pools. My personal pool is also a salt pool and has been for the past nine years. Some of the benefits are: A good chlorine level all of the time. Softer water and no chemical smells. You get away from handling chemicals that are known carcinogens. Makes maintaining your pool much easier. Salt Water Generators are reliable and easy to operate (most of them are reliable). Eliminates the need for shocking your pool. Most Salt water Generators will have a Super Chlorinate mode. Some of the drawbacks: Higher cost of maintaining your pool. A slight learning curve. Some cities restrict draining a salt water pool. PH will constantly rise in a salt pool. Cannot be installed in a pool with copper pipes. So after watching the video I hope you feel more confident about making a more informed decision if a salt water generator is right for you or not. If you have questions or need help picking out the right salt system you can comment here or contact me on my website and I will further assist you.

GFDL Global Sea Surface Temperature Model
This dataset shows how the global ocean's surface water temperatures vary over the course of few years. In addition to seeing the effects of the seasonal cycle, the viewer can see how surface ocean currents and eddies transport heat and water around the globe. The images were generated not from observations, but from a state-of-the-art computer model of Earth's climate created at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL). http://sos.noaa.gov/Datasets/dataset.php?id=132
