Marine olfaction in different temperatures of water?
453515
Tough question!  I really only have a hypothesis, so I'm not sure if this will help.\n\nSmell is triggered by suspended particles in a fluid (air or liquid are both, technically, fluids).  The higher the concentration, the higher the strength of the olfactory stimulation.  As per basic physics, temperature is a measure of the activity of the particles.  So in terms of the particle activity, warm water is moving faster, meaning the scent particles are being diffused away fast, making it more difficult to track them back to their source.  So my guess, based on this theory, is that cold water would leave a shorter but more intact scent trail back to the source.

i dont think theres many areas on the east coast,,my guess is that west coast waters are warmer

The concentration of salt in seawater varies with temperature.  Because the Arctic and Antarctic oceans are colder than the Indian Ocean and South China Sea, the salt is less soluble.  By the same principle, seawater near the floor of the ocean would be less salty because it's cold down there.  Throw in a few baby volcanoes, the Atlantic rift and a few dozen fumaroles, etc...  Then, you would have to know how many liters of water are in the oceans and that quantity is constantly changing.  Now, are you talking about common NaCL?  Or do you want to include all the sulfates, carbonates, phosphates, etc... which are all in the ocean?  Thanks for the easy 2 points!

The speed of sound in water (including seawater) depends on several factors, but most important is the the temperature of the water.  By measuring the time it takes for an acoustic signal to travel from a source to a receiver, one can determine the average temperature along the path followed by that sound signal. (Other factors that include sound velocity or travel time include salinity, pressure (i.e. pressure-induced changes in density), and ocean currents.)  By measuring the average temperature along many different paths, one can reconstruct a 3-dimensional "map" of the temperature distribution in the oceans.  \n\nBy following the changes in temperature over time, one can detect long-term changes in the temperature distribution and hence average temperatures of the oceans.

The temperature of the ocean at depth, anything more than several hundred feet, is 3.98 degrees C.  This is the temperature at which water is densest.\n\nIf any geothermal heat from the sea floor warms the very deepest water, it becomes less dense and rises.  And any shallower water warmed by the sun is too buoyant to descend towards deeper water.  3.98 degrees C is it, all the way to the bottom.

generally people prefer about 70 degrees F. It can be lower but people in general will find it too cool. Some might find even 70 overly cool. Remember body temperature is 98 and water is a good conductor of heat. If it is sunny and warm outside, the water can be cooler and feel comfortable than if it is not. On a cloudy cool day, 80 water termperature will feel much better than 70.

Did you ever wonder why the oceans are filled with salt water instead of fresh? Just where did the salt come from? And is it the same salt you find on a dining room table? Most of the salt in the oceans came from land. Over millions of years, rain, rivers, and streams have washed over rocks containing the compound sodium chloride (NaCl), and carried it into the sea. You may know sodium chloride by its common name: table salt! Some of the salt in the oceans comes from undersea volcanoes and hydrothermal vents. When water evaporates from the surface of the ocean, the salt is left behind. After millions of years, the oceans have developed a noticeably salty taste.\n\nDifferent bodies of water have different amounts of salt mixed in, or different salinities. Salinity is expressed by the amount of salt found in 1,000 grams of water. Therefore, if we have 1 gram of salt and 1,000 grams of water, the salinity is 1 part per thousand, or 1 ppt.\n\nThe average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt.\n\nFreshwater salinity is usually less than 0.5 ppt. Water between 0.5 ppt and 17 ppt is called brackish. Estuaries (where fresh river water meets salty ocean water) are examples of brackish waters.\n\nMost marine creatures keep the salinity inside their bodies at about the same concentration as the water outside their bodies because water likes a balance. If an animal that usually lives in salt water were placed in fresh water, the fresh water would flow into the animal through its skin. If a fresh water animal found itself in the salty ocean, the water inside of it would rush out. The process by which water flows through a semi-permeable membrane (a material that lets only some things pass through it) such as the animal's skin from an area of high concentration (lots of water, little salt) to an area of low concentration (little water, lots of salt) is called osmosis.\n\nThis is also why humans (and nearly all mammals) cannot drink salt water. When you take in those extra salts, your body will need to expel them as quickly as possible. Your kidneys will try to flush the salts out of your body in urine, and in the process pump out more water than you are taking in. Soon you'll be dehydrated and your cells and organs will not be able to function properly.

Depends on the quantity of ice in the water, time you measure it at, etc. All depends on the precise details of the experiment.

you meant oder . in that case  mixing it with large amount water  reduces its smell it does not change its properties it is termed as fomalin

Ca dépend quand-même beaucoup de la température de l'eau. Si tu vas te baigner dans une piscine à 27°C juste après un repas, tu ne risques pas grand chose !

It really depends on how warm the water is, some fishes (different species) do thrive in warm climate/ water

There are a number of currents in the ocean in which the water temperature is different from the surrounding area.  The most famous of these is the Gulf Stream that brings warm water from the tropic areas north off the East Coast of the United States and then across the Atlantic to Europe.\n\nNote that this movement is clockwise if you look at it from space.  Of course, this also means that on the other side of the ocean, cold water will move south to complete the circuit.\n\nNow we go to California.  There is a cold current called the California current that brings water from the area off Alaska in the same manner.  This cold water is also full of nutrients which is why there are the kelp forest and abundant wildlife.  It moves in the same manner as the Atlantic Ocean example.\n\nHope this answers your question.

Depends on the tempertaure of the water amongst other things.

THere are layes of the ocean with differing salinity (salt) concentrations.  I don't think that a layer as you described could exist.  Buoyancy is a result of several factors.

At room temperature and 1 atmosphere of pressure air is much less dense than water.  So, even if the molecules in air/perfume are moving at the same rate as those in the water/alcohol mixture, the perfume molecules will go farther before they collide with an air molecule.  Thus, perfume in air will diffuse much faster than alcohol in water.  \n\nBTW, I must correct blackdragon's comment that alcohol does not mix with water.  Most common short chain alcohols, such as methanol (wood alcohol), ethanol, and isopropanol mix well with water.  Ethanol is the alcohol in beer, wine, and other alcoholic drinks.

you observe it at room temperature.\n\nyou can do this by :\n\n1. smelling it ( it smells like clorox or a swimming pool.\n\n2. run it thru water- it will bubble and dissolve causing the water to smell like the above.\n\n3. use chemical analysis to confirm the gas is chlorine at room temp.\n\nhope it answers you question ( unusual )
