biogeochemist cyclone?

Perhaps that's a cyclone that chemically changes biological matters into geological ones. Seriously, it can be a kind of turbine that turns matters to others by its cyclonic effect.

Yes and no. Methane is generated constantly from decomposing organic matter,but not in enough quantity for humans to use. Nature cannot keep up with our demand! :-)=

Probably 100%. Its hard to determine this because nature is so unpredictable and if it could be determined, trust me, some scientist would have figured it out already. Nature kinda does what it wants to so its a chance you'll have to take. I dont know where you stay now, but with the whole global warming thats going on, its very possible that a natural disaster can occure there. There is no way of knowing.

Oh I know,  I know, is it the ozone? neeee Oh I'm sorry the answer we were looking for was actually atmosphere. Sorry little johnny better luck next time on guess that ocean of air around the Earth.

Absolutely.  Interestingly enough, though, there is also such a thing as particle refraction.  This is the pollution particles (mostly sulfates) in the air forming droplets and mixing with clouds.  These smaller particles reflect more light than unpolluted drops, therefore refracting much light and warmth from the earth.  This is referred to as global dimming.  Global dimming actually helps to balance out the global warming.  If we were to somehow end all particle pollution, then the earth would warm at a faster rate.  Without the global warming, the particle pollution would eventually freeze us out.  Therefore, if we end either process of pollution, we must end both or the earth will suffer grave consequences.  If you want more proof of global warming, investigate the hurricane trend of the last few years.  We have had an increase in the frequency of hurricanes because the ocean waters are warmer--check National Geographic, I remember an article in August or September of last year.

well, scientists and meteorologists theorise that because of global warming, the ocean's waters are getting warmer and causing more hurricanes and tropical storms to spawn. also, the earth is the warmest it's been in over 2000 years. all you need to know, WE BEAT THE RECORD! :P

For a very good explanation start here:\n\nhttp://clearlyexplained.com/nature/earth/disasters/cyclones.html\n\nIf you want some additional information read on:\n\nCyclones\n\nThe terms "hurricane" and "typhoon" are regionally specific names for a strong "tropical cyclone". A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).\n\nTropical cyclones with maximum sustained surface winds of less than 17 m/s (34 kt, 39 mph) are called "tropical depressions" (This is not to be confused with the condition mid-latitude people get during a long, cold and grey winter wishing they could be closer to the equator ;-)). Once the tropical cyclone reaches winds of at least 17 m/s (34 kt, 39 mph) they are typically called a "tropical storm" and assigned a name. If winds reach 33 m/s (64 kt, 74 mph)), then they are called:\n\n    * "hurricane" (the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, or the South Pacific Ocean east of 160E)\n    * "typhoon" (the Northwest Pacific Ocean west of the dateline)\n    * "severe tropical cyclone" (the Southwest Pacific Ocean west of 160E or Southeast Indian Ocean east of 90E)\n    * "severe cyclonic storm" (the North Indian Ocean)\n    * "tropical cyclone" (the Southwest Indian Ocean) \n\nHow they are Caused\n\nGo to this link for a diagram:\n\nhttp://www.aoml.noaa.gov/hrd/tcfaq/A15.html\n\nTo undergo tropical cyclogenesis, there are several favorable pre cursor environmental conditions that must be in place (Gray 1968,1979) :\n\n1. Warm ocean waters (of at least 26.5°C [80°F]) throughout a sufficient depth (unknown how deep, but at least on the order of 50 m [150 ft]). Warm waters are necessary to fuel the heat engine of the tropical cyclone.\n\n2. An atmosphere which cools fast enough with height such that it is potentially unstable to moist convection. It is the thunderstorm activity which allows the heat stored in the ocean waters to be liberated for the tropical cyclone development.\n\n3. Relatively moist layers near the mid-troposphere (5 km [3 mi]). Dry mid levels are not conducive for allowing the continuing development of widespread thunderstorm activity.\n\n4. A minimum distance of at least 500 km [300 mi] from the equator. For tropical cyclogenesis to occur, there is a requirement for non-negligible amounts of the Coriolis force to provide for near gradient wind balance to occur. Without the Coriolis force, the low pressure of the disturbance cannot be maintained.\n\n5. A pre-existing near-surface disturbance with sufficient vorticity and convergence. Tropical cyclones cannot be generated spontaneously. To develop, they require a weakly organized system with sizable spin and low level inflow.\n\n6. Low values (less than about 10 m/s [20 kts 23 mph]) of vertical wind shear between the surface and the upper troposphere. Vertical wind shear is the magnitude of wind change with height. Large values of vertical wind shear disrupt the incipient tropical cyclone and can prevent genesis, or, if a tropical cyclone has already formed, large vertical shear can weaken or destroy the tropical cyclone by interfering with the organization of deep convection around the cyclone center.

its a giant storm  like a hurricane thats been going on for a logn time bout size of earth i think

Saw an interesting program on this on the Science channel recently.  Basically scientists think it was because of a mega volcano that erupted that cause the first stage of the extintion.  Then world wide temperature rised 5 degrees and the methane in the bottom of the ocean evaporated and contributed to a super global warming and that raised the Earth's temperature another 5 degrees.  That was the most devastating extintion the planet saw and most of life on Earth and the Ocean died.

I am working on this problem without knowing if you even still need this info. But it is interesting. It seems the most important inorganic nutrient is sunlight!\n\nHere's a quote:\n\nAutotrophs absorb sunlight energy and transfer inorganic mineral nutrients into organic molecules. The autotrophs of the marine environment include algae and flowering plants and in the deep sea are chemosynthetic bacteria that harness inorganic chemical energy to build organic matter...AUTOTROPHIC NUTRITION..supply food molecules to organisms that can't absorb sunlight.\n\nfrom:http://darter.ocps.net/classroom/klenk/Ecology.htm\n\nHere's another link relative to the subject, I think:\nhttp://pubmedcentral.com/articlerender.fcgi?artid=18283\n\nThe oceanic distribution of cadmium follows closely that of major algal nutrients such as phosphate. The reasons for this “nutrient-like” distribution are unclear, however, because cadmium is not generally believed to have a biological function. Herein, we provide evidence of a biological role for Cd in the marine diatom Thalassiosira weissflogii under conditions of low zinc, typical of the marine environment. Addition of Cd to Zn-limited cultures enhances the growth rate of T. weissflogii, particularly at low pCO2. This increase in growth rate is reflected in increased levels of cellular carbonic anhydrase (CA) activity, although the levels of TWCA1, the major intracellular Zn-requiring isoform of CA in T. weissflogii, remain low. 109Cd label comigrates with a protein band that shows CA activity and is distinct from TWCA1 on native PAGE of radiolabeled T. weissflogii cell lysates. The levels of the Cd protein are modulated by CO2 in a manner that is consistent with a role for this enzyme in carbon acquisition. Purification of the CA-active fraction leads to the isolation of a Cd-containing protein of 43 kDa. It is now clear that T. weissflogii expresses a Cd-specific CA, which, particularly under conditions of Zn limitation, can replace the Zn enzyme TWCA1 in its carbon-concentrating mechanism.\n\nMarine microorganisms are largely responsible for the cycling, and therefore the distribution, of many nutrients in the sea, and it is the availability of these nutrients that, in turn, controls oceanic primary production. This relationship is as true of essential trace elements as it is of major nutrients. In oceanic systems, the water column distribution of many biologically important trace metals is thus similar to that of the major nutrients: phosphate, nitrate, and silicate. At the surface, where photosynthetic activity depletes algal nutrients, such metals are present at extremely low concentrations, presumably as the result of biological uptake. Like those of major nutrients, these metal concentrations increase at depth because of decomposition of organic matter and remineralization.\n\nZinc, which has many known biological functions (1), is a good example of a metal that follows this type of nutrient-like profile. Cadmium, however, which is generally thought to be universally deleterious to living organisms, also has a nutrient-like profile (2); its concentration is so well correlated to that of phosphate that the accumulation of Cd in the fossilized tests of marine invertebrates is used as a measure of past nutrient concentrations in the sea (3). In the absence of a demonstrated biological function for Cd, it has been widely thought that abiotic processes, such as adsorption onto organic particles, modulate the distribution of this metal. Recently, it has been proposed that the depletion of Cd from surface seawater is caused by its use by marine phytoplankton (4). Under conditions of Zn limitation, Cd enhances the growth rate of some marine phytoplankton in culture (4–6), and it thus seems that Cd may replace Zn in some essential biochemical function.\n\nIn Thalassiosira weissflogii, the enzyme carbonic anhydrase (CA) constitutes a major use of cellular Zn (7), and the expression of TWC

There's lots of stuff blowing up from lots of places.  Dust storms in the Sahara desert blow tons into the Atlantic ocean.  Volcanos in the southwestern Pacific will color the North American skies.  The atmosphere has a lot of currents.  The jet stream is one, prevailing winds are another.\n\nThe earth has bands of atmospheric rotation.  I live in a zone called the prevailing westerlies.  Most of the winds tend to flow in a west to east direction.  If you are in North America, that Scandinavian pollen will have traveled the width of Asia, at its widest, raining down all along the way.  This shows the global nature of this zone of air flow.\n\nSomethings are simply too big for those zones to contain, in 1883 when Indonesian volcano Krakatoa exploded, its ash was seen in England.  May I suggest an article by Timothy Miner in the May 1, 2003 issue of Flying Safety.  Not all pollen, dust, pollutants travel that far.  Some are not as aerodynamic as others, and sometimes winds are not as strong when the pollination is taking place.  Still, there are times when smoke, ash, pollen, and other things can travel long, long distances when they are usually confined to very short areas.\n\nIf you have ever seen photos of great dust storms, consider that we call them sand storms, but the sand is only blowing up a very few feet from the ground.  Those enormous clouds of dirt are the dust the wind carries high into the air, taking them miles and miles away from their source, while the original sand the dust was shaken out of has fallen but a few fee from its original disturbance.  Pollen works that way too.

They have been and will be... meteors and other foreign objects entered earth have some microbes in it. Some would survived along the way if they could withstand the burning heat as they hit the earth's atmosphere.

In meteorology, a tropical cyclone is a storm system with a closed circulation around a center of low pressure, fueled by the heat released when moist air rises and condenses. The name underscores their origin in the tropics and their cyclonic nature. They are distinguished from other cyclonic storms such as nor'easters and polar lows by the heat mechanism that fuels them, which makes them "warm core" storm systems.\n\nDepending on their strength and location, a tropical cyclone can be called a tropical depression, tropical storm, hurricane, or typhoon, among other names.\n\nTropical cyclones can produce extremely high winds, tornadoes, torrential rain (leading to mudslides and flash floods), and drive storm surge onto coastal areas. Though the effects on populations and ships can be catastrophic, tropical cyclones have been known to relieve drought conditions. They carry heat away from the tropics, an important mechanism of the global atmospheric circulation that maintains equilibrium in the environment.\n\nthey r just d same\n\nTerms used in weather reports for tropical cyclones that have surface winds over 64 knots (73.6 mph) or 32 m/s vary by region:\n\nHurricane: Atlantic basin and North Pacific Ocean east of the International date line \nTyphoon: Northwest Pacific west of the dateline \nSevere tropical cyclone: Southwest Pacific west of 160°E and the southeast Indian Ocean east of 90°E \nSevere cyclonic storm: North Indian Ocean \nTropical cyclone: Southwest Indian Ocean and the South Pacific east of 160°E. \nCyclone (unofficially): South Atlantic Ocean \nThere are many regional names for tropical cyclones, including baguio in the Philippines and Taino in Haiti.

when I was in my teens, I aspired to be a marine biologist. i had a good microscope at the time but i didn't make the connection between the two!!!  i used to scuba dive and in central Fl. I have been on reefs where i came within 10 ft. of a barracuda!! it just watched me as i watched it.  i made sure that i didn't have on any jewelry like bracelets, necklaces or any shiny things that may have caused it to assume i was a fish!  used to watch J. Cousteau (sic) all the time. recently, i was a fan of the late Steve Irwin.  i used to look at plankton under my microscope but didn't realize that the lowest part of the food chain sustained all of us.  I think marine microbiology is a vital occupation and i should have went in that direction going into college. hindsight is allways 20/20 as they say.   good question that brought back good memories so thanks.  BTW you know that SCUBA is an acronym for Self Contained Underwater Breathing Apparatus.

I am very concerned with the rash of natural disasters that are happening and can only really attribute them to global warming. Our planet has the ability to "rebuild" the ozone, but not quickly enough at the rate we are depleting it. I think as Americans and as a consumer nation, we need to get on the clue train about how much we are harming our world by car emmisions and we need to switch to a clean alternative. It's possible, but we fear change.

This is not a pure biology question. Should be bio-chemistry.
