Where Is Row M In The Rose Garden

ship and simulations

here now why we go to the description there and what we do there. I take just 1-1 since the press release as it is just as common:
"[..] end of November will go then in Chile, mainly marine geologist on board for the first time to traverse the entire star with polar polar South Pacific The 43 scientists. and technicians around cruise leader Dr. Rainer Gersonde of the Alfred Wegener Institute will take approximately 40 positions geological samples in order from the to collect deposits of deep-sea data on climate history of the past million years. The analysis made in the context of national and international projects, "

the entire text with pictures can be found at the AWI website

From I have also stolen the picture with the current position of the North Star. As you can see they already on the way to Punta Arenas. Furthermore, there are still a virtual tour and technical data .

Yesterday was the Antarctic environment seminar that everyone of a German institution belongs and Antarctica moves must participate. Article 1 of the Antarctic Treaty states that the only peaceful and Antaktis scientific purposes may be used. So now I have a certificate and may not official south of 60 ° S. I have the opportunity then also be used and identified with two Mädls hiking in New Zealand.

But again to my work. Yes I finally calculation results, although not yet of semi-lagrange, all part of the actual. But I think now knowing how to do it and wants the program before the end schifferlfahren. But here are a nice plot:






Then we see a cross section of an artificial gray hills covered with ice. This is an artificial Ice sheet with which to compare models. I've used to have fall, where one can still imagine how the ice would have to flow around a simplified. Fill in the center and outside snow will melt around it instead. The simulation begins with bare rock on because then only in the middle of snow falls. In 200 years 100 meters. 200 years of the time step with the model for this simulation works. Accumulates enough ice time then it starts to flow, like a pizza dough. It cuts the dough dumplings on the table, and slowly he begins to diligence and is flatter. Similarly behaves the ice flowing well, albeit very slowly. What you see here are so a few snowflakes falling after 4000 years on the surface. This surface is the red line. Then seiht how this marked snowflake is transported through the ice. You can see the the oldest ice of nearby soil and that the oldest ice in the middle, at the highest point of the ice, the so-called "cathedral". There would also drill to an ice core because it is so interested in as the old ice and a continuous time series. The lines already aiming at 1000 meters apart which makes it difficult to date the finding and therefore no longer just the ice that has fallen at this point on the surface.

Dans whole works for Greenland and Antarctica where I still single pair will make experiments and even talk with a glaciologist it. With semi-Lagrangian, it is then, hopefully soon be possible not only still pictures but make the entire stratification and the ice-age, etc. to behold. But the good times something works and something interesting happens.
