During the yearly ice melt process, the diatoms are released back into the water, resulting in local increased primary productivity. This period saw the mass extinction of many corals, brachiopods, and trilobites. Of the notyourshield fake grass roots campaign. Penguins would much rather swim in the ocean than walk on sea ice that covers it. His book, Dead Men’s Secrets, catalogues more than a thousand pieces of evidence of a lost super science and technology, including dozens of achievements ahead of our day.

None of these claims has international recognition and, under the Antarctic Treaty System, the respective countries do not attempt to enforce their claims. Because they stay above a fixed spot on the surface, they provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms, and hurricanes. There is a significant amount of ice covering Greenland, which would add another 7 meters (20 feet) to the oceans if it melted.

At the base of the thermocline is the low salinity Antarctic Intermediate Water (AAIW) derived from sinking of cool (3° to 4°C), low salinity waters (34.4) from 50° - 60°S marking the Antarctic Circumpolar Current and ocean polar front zone. Other planets and natural satellites in the solar system have interesting quirks about their polar regions. Unlike most large carnivores, the current distribution of polar bears is similar to that of the last few hundred years. In these climates all months have average temperatures greater than 18° Celsius.

However, polar bears would really like the Antarctic. Other than various scientists that are almost always present in the area, Antarctica is the world�s only completely uninhabited continent. Chunks of ice fell into the waters creating huge tidal waves and every iceberg was mor impressive than the next. This area is dominated by small accumulations of snowfall which becomes ice and thus eventually seaward glacial flows.
