CO2 bonds in sea ice: Small living creatures with major impact

Due to the presence of salts, the freezing point of sea water is below zero. During freezing, channels in which the salt accumulates, so-called "brine channels," are formed in the ice. They serve as a habitat for microorganisms. Together with collegues, a scientist from the Helmholtz-Zentrum Dresden-Rossendorf is currently analyzing the characteristics and distribution of these channels in which CO2 is bound by the organisms which, in turn, diminishes the greenhouse effect.

Under normal conditions, water freezes at zero degrees Celsius. But not salt water: Due to the presence of salts, the freezing point of sea water is below zero. And sea water tends to freeze unequally. During freezing, channels in which the salt accumulates, so-called "brine channels," are formed in the ice. The high permits the contents of these channels to remain in a even at lower temperatures, and they serve as a habitat for microorganisms. Together with colleagues, a scientist from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is currently analyzing the characteristics and distribution of these channels in which CO2 is bound by the organisms which, in turn, diminishes the .

The existing microorganisms are called diatoms and are at the bottom of the food chain in the marine ecosystem of the polar region. They also convert about 20 percent of the global CO2. The scientists want to understand how the tiny channels and their dwellers are distributed in the ice, what structures they exhibit, and under which circumstances they change. "Direct measurements of these structural properties are not possible without impairing the habitat," explains Dr. Sibylle Gemming from the HZDR. "That's why we're developing mathematical models which will be the basis for ." The comparison of simulated and measured properties will permit conclusions to be drawn about the channel formation process.

According to the scientists, the findings of their research could serve as input variables for global climate models. That is why German researchers from Dresden, Bremerhaven (Alfred Wegener Institute for Polar and Marine Research within the Helmholtz Association), and Münster (Münster University of Applied Sciences) are also cooperating with colleagues from the Norwegian Polar Institute in Tromsø. The project, which is subsidized by the German Academic Exchange Service (DAAD) and the German Research Foundation (DFG), is headed by the quantum particle physicist Prof. Klaus Morawetz (Münster University of Applied Sciences).

Oliver Manuel's recent efforts to plaster Physorg.com and other public news sites with his theories and personal URLs are a bit puzzling, as scientists have a variety of publications available to communicate directly to each other in. My best guess is that he is desperately trying to prop up his legacy in light of his arrest in his university office on 7 charges of rape and sodomy based on allegations by 4 of his own children. The charges have been reduced to one count of felony attempted sodomy, not necessarily because of his innocence, but because of the statute of limitations. One can only guess how the recent charges and decades of family strife have affected his ability to reason rationally and to remain objective while defending his unpopular theories.

But Oliver the Sun doesn't exist. Your theory shows us.

You insist there is such a thing as neutron repulsion. You insist it is strong enough to stop the formation of black holes, not just stellar black holes but ALL black holes no matter what the size. Also it you claim it is long ranged enough to sunder galaxies. Though you refuse to answer any question about its actual strength or range those claims make it clear that it MUST be more powerful than gravity per unit of mass even if the mass is mostly hydrogen atoms as we can see makes up most the mass in the in the Universe, based on your denial of Dark Matter that is.

It really doesn't require a great deal of effort to notice that there is a severe problem with that set of claims. They make galaxies, stars, even neutron stars, planets and pretty much everything held together by gravity impossible.>>

Please explain this contradiction of reality that is an inevitable conclusion based on your own claims for Neutron Repulsion
