由于大气层里的碳水平太过于高,导致海水酸性增加而阻止这些海底生物制造贝壳。。。


想问下。。

海水酸性增加 是不是 由于 气层里的碳水平太过于高 而 融于海水  ??

而使海水 变  酸性 ?

而 碳 是什么东西 排放出来 还是 自然气体 。。。

谢谢。。

这些照片应该不是一般的潜水员拍的呱?
若不用潜水艇下深海应该拍不到吧?

碳(carbon)本来就会融入水里,是多还是少而已。。。
如果大气层里的碳越多溶入水里的自然就变多。。
碳混合体是酸性的。。
通常碳混合体比如:二氧化碳,carbon monoxide等等,是由交通工具,燃烧垃圾,工厂等等。。oh对了还有你所排出的咯

而 碳 是什 ...


海水的 pH (pH<7是酸性,pH>7是碱性) 是大约 8.0-8.5,看区域而定。

海里的植物需要二氧化碳,CO2 来进行光合作用才能排出氧气,O2。所以白天的时候,pH 会稍为高一些,因为植物吸取 CO2。晚上的时候,所有生物(动物+植物)都需要O2来呼吸(新成代谢)而排出 CO2,所以 pH 会低一些。整个海里的 Carbon Cycle 是自动平衡,但当人类制造太多污染,造成有些海域的植物不能生存,整个系统就会慢慢崩溃了。不只是车辆+工厂排出的废气,人类丢下水中(沟渠的废物会流进河流再进入海中)的垃圾,还有没有节制的森林/土地开发所造成的 siltation (沙泥淤积)把珊瑚礁掩盖,植物的数量少了很多。不要忘记,虽然珊瑚是动物(有谁不知道这一点?),它体内也有植物的存在(共生藻)。大家应该有经验,当大雨过后,visibility (能见度)会降低很多。能见度不好也就是说太阳的光线渗透度减少,那深水的植物就会慢慢减少。

我也不知道写了这些东西大家会明白吗?也不知道我的预测对不对?大家可以指点我一下吗?

如果是在深海的话, 光线其实并不那么重要了。。。
如果那里还是有植物的话,可能他们已经以别的物体来代替了。。。
不过通常在深海比较少植物。。。。

就是说 碳 + 二氧化碳,carbon monoxide等等 就会 变成碳混合体 ,

而这碳混合体 融入 海水里 ,导致海水酸性增加而阻止这些海底生物制造贝壳。。。。

如纯正的碳 , 对自然界有什么用处???

它会不会 减少 呢 ???

海胆的其中一种。。。
This vibrant animal, called Ctenocidaris, was captured by biologists during explorations of the deep seas around Antarctica.
The Antarctic Benthic Deep-Sea Biodiversity Project, or ANDEEP, catalogued more than 700 new species during expeditions between 2002 and 2005. The ANDEEP cruises were also the first to study the DNA of deep-sea species in the oceans off Antarctica.
“The great advantage in the Antarctic is that the water column is cold all the way up,” said Angelika Brandt, a marine biologist at the University of Hamburg in Germany, “so we can bring material up on deck and extract DNA before it becomes damaged by heat.”


Ceratoserolis is just one of 585 new species of isopod—a type of marine crustacean related to wood lice—found during the Antarctic Benthic Deep-Sea Biodiversity Project, or ANDEEP, trips between 2002 and 2005.


This shrimplike creature, called Cylindrarcturus, was caught floating through the deep waters near Antarctica.
Most of the more-than-700 species snapped up by scientists were very small—less than 0.2 inches (about 5 millimeters)—and nearly all, like Cylindrarcturus are ghostly white. “It's so deep and dark down there, you don't need any color,” said Katrin Linse, a marine biologist at the British Antarctic Survey.


This glass sponge was one of 76 sponge species found during expeditions in the seas off Antarctica between 2002 and 2005. Seventeen species of sponges had never been found before and 37 were not known to live in those waters.
The richness of the deep-sea fauna found during the trips challenged a belief that the ocean depths do not nurture a diversity of animals.
“In other oceans the number of species drops the deeper you go,” said study co-author Katrin Linse, a marine biologist at the British Antarctic Survey. “But in the Southern Ocean we found the opposite trend.” The Southern Ocean includes the Indian, Atlantic, and Pacific Oceans surrounding Antarctica.


我还以为是虾呢。。。
This unusually shaped organism, a male Munna, was snagged during a deep-sea expedition in the waters around Antarctica between 2002 and 2005. Munna and more than 700 new species discovered during the research efforts provide some of the first insights into the biodiversity of the oceans around Antarctica, long an enigma to scientists.

戴着海盗帽子的章鱼。。。海盗王是不是你的手下?
This previously unknown squid was among 80,000deep-sea organisms collected from the northern Mid-Atlantic Ridge, achain of undersea mountains halfway between Europe and North America.                                                                                                 
The species, dubbed Promachoteuthis sloani, wascaught along with around 50 other types of squid during trawls as deepas 1.2 miles (3 kilometers) by a Census of Marine Life team. The team,from the Norwegian-led MAR-ECO program, is investigating life along theworld's ocean mountain ranges.
The new species has unusually small, semi-opaque eyes and large numbersof suckers on its arms. The shape of its beak suggests the squid is apowerful chewer, MAR-ECO researchers say.
While soft-bodied squid are often damaged during deep-sea trawls, theirhard mouthparts are unique to each species and so can be used to helpidentify different species, the team says.
The new specimen has also provided material to help flesh out thephysical descriptions of previously discovered but poorly known relatedspecies, the researchers add.
Around 60,000 of the organisms collected during the Mid-Atlantic Ridgesurvey were fish, which experts are working to document and identify.


像UFO的水母。。。
Dark Dweller: Antarctic JellyfishDiscovered during a 2006 Census of Marine Life expedition, this specieswas filmed in Antarctic waters that have been kept in darkness forthousands of years by thick ice cover.
Researchers were able to finally shed light on the species—and scoresof other tiny creatures—by suspending an underwater camera down a holedrilled through 2,300 feet (700 meters) of ice.
The diversity of life supported by unlit waters was a big surprise forAntarctic researchers who conducted the survey in the Weddell Sea (interactive Antarctica map).
Census of Marine Life senior scientist Ron O'Dor said the findingsshowed "there are no deserts in the ocean. Everywhere we look, we findevidence of life."





恐龙时代的虾。。。在深海被发现。。

Jurassic ShrimpCensus of Marine Life researchers got a big surprise when they trawled up this "Jurassic shrimp."
The scientists were documenting life on undersea mountains, orseamounts, in the Coral Sea off northeast Australia when they foundthis specimen (Australia map). It belongs to a species thought to have died out some 50 million years ago.
Caught at a depth of 1,300 feet (400 meters), the new species isdescribed as a "living fossil" by survey member Bertrand Richer deForges, a marine biologist based in nearby Noumea, New Caledonia.
Neoglyphea neocaledonica belongs to an ancient group ofcrustaceans that were "well known from the Jurassic and Cretaceousperiods [roughly 200 to 65 million years ago] and were supposed to beextinct," de Forges said.
The find follows the discovery of a related species in Philippine waters in the 1970s.
De Forges compares the new catch to the discovery of a secondspecies of the primitive coelacanth in Indonesia in 1997. Thisso-called fossil fish was first rediscovered off South Africa in 1938,showing it hadn't gone extinct in the Cretaceous period as previouslythought.


Needle in a Haystack—IsopodThe Census of Marine Life's ambitious goal is to document all life inthe oceans, a task made even harder by creatures that are verydifficult to tell apart, such as this little isopod.
Isopod crustaceans include both rare and abundant species. Forcensus researchers, trying to sort out which is which can be likefinding needles in a haystack.
The isopod pictured above was one of these needles, found by a teamsurveying waters around Antarctica. The researchers documented many newisopod species from the thousands of specimens collected. Some specieswere represented by just a single animal.
"The vast expanse of the oceans, the rarity of some animals,their movements and fluctuations challenge census researchers," saidJesse Ausubel, a program manager for the Sloan Foundation, a supporterof the project.
"Happily," she added, "the astonishing progress of the past sixyears [the census began in 2000] shows the community will create thefirst ever Census of Marine Life in 2010."



毛蟹。。。好像10,000BC里的毛象。。长满毛的
Furry CrabThe "yeti crab," discovered on the floor of the Pacific Ocean, is soextraordinary that a new taxonomic family had to be invented for it.
The new species was found during a deep-sea dive expedition, some 900 miles (1,500 kilometers) off Easter Island.
Living next to hydrothermal vents at depths of 7,540 feet  (2,300 meters), the blind white crustacean, named Kiwa hirsute, was also dubbed the yeti (or abominable snowman) crab because of its hairy arms, which support colonies of yellow bacteria.
Led by the Monterey Bay Aquarium Research Institute inCalifornia, the dive team speculates that the animal may deliberatelycultivate these bacteria for food or as tiny sensors that help the crabfind food or a mate.
Other researchers suggest the crustacean could use the bacteria to combat toxic fluids that rise from the volcanic vents.
Mineral-eating bacteria thrive on deposits from the vents, saysChris German of the Southampton Oceanography Centre in England. "Showthem a metal sulfide deposit on the seafloor and they think it's asix-course banquet," he joked.
"If you've got things that want to [eat toxic fluids], why not carry abunch of them around with you if you're working in a hazardousenvironment," German added. "They could be your natural safeguards."




Deepest DwellerThe deepest census survey took place more than three miles (fivekilometers) down in the Sargasso Sea in the North Atlantic. There,researchers trawled up more than 500 species of microscopic animalscalled zooplankton. Twelve are likely to be new species.
The researchers used sophisticated nets that can be individually closed and opened at the touch of a computer key.
The team's catch included many strange and menacing lookingspecies, such as the one pictured—a prawnlike crustacean called anamphipod. An amphipod supposedly inspired the monster in the movie Alien.
These extreme deep-sea species survive by eating each other or bylatching on to dead fish and other organic matter that floats down fromabove, researchers say.
Further surveys are planned by the team, which estimates that at least1,600 new zooplankton species will be discovered worldwide by 2010.
The team says most previous studies of ocean zooplankton have focusedon species living at depths of fewer than 1,000 meters (3,280 feet).Below that level, little is known about zooplankton diversity,distribution, and abundance.
