what happened to the core of ice ?
A comparison of the delta profiles at Byrd Station, West Antarctica and Camp Century, Northwest Greenland suggested that in these two locations the Holocene climatic optimum (post glacial climatic optimum) probably occurred at the same time.
Holocene climatic optimum
A comparison of the delta profiles at Byrd Station, West Antarctica (2164 m ice core recovered, 1968) and Camp Century, Northwest Greenland, shows the post glacial climatic optimum. Points of correlation indicate that in these two locations the Holocene climatic optimum (post glacial climatic optimum) probably occurred at the same time. 
how can you tell if a great white shark is a male or female n great white sharks, sexual dimorphism is present, and females are generally larger than males. where are these sharks found? United States (Northeast and California), South Africa, Japan, Oceania, Chile, and the Mediterranean including Sea of Marmara and Bosphorus. what do they feed on? Fish (e.g. tuna, rays, other sharks), cetaceans (i.e., dolphins, porpoises, whales), pinnipeds (e.g. seals, fur seals, and sea lions), etc. how are these sharks used to attract tourists? Cage diving is most common at sites where great whites are frequent. where is this activity famous? The coast of South Africa, the Neptune Islands in South Australia, and Guadalupe Island in Baja California. how were the first island group formed? The sea levels rose at the start of the Holocene. how can this mentioned time period be defined? It began approximately 11,650 cal years before present, after the last glacial period, which concluded with the Holocene glacial retreat. what changes did it bring to the mankind? Its beginning corresponds with the beginning of the Mesolithic age in most of Europe, but in regions such as the Middle East and Anatolia with a very early neolithisation, Epipaleolithic is preferred in place of Mesolithic. what climatic conditions were brought about by this period? he Holocene climatic optimum (HCO) was a period of warming in which the global climate became warmer. how would you define the optimum? It was a warm period during roughly the interval 9,000 to 5,000 years BP, with a thermal maximum around 8000 years BP.

Holocene climatic optimum [SEP] Comparison of ice cores
A comparison of the delta profiles at Byrd Station, West Antarctica (2164 m ice core recovered, 1968) and Camp Century, Northwest Greenland, shows the post glacial climatic optimum. Points of correlation indicate that in these two locations the Holocene climatic optimum (post glacial climatic optimum) probably occurred at the same time. A similar comparison is evident between the Dye 3 1979 and Camp Century 1963 cores regarding this period. The Hans Tausen Iskappe (ice cap) in Peary Land (northern Greenland) was drilled in 1977 with a new deep drill to 325 m. The ice core contained distinct melt layers all the way to bedrock indicating that Hans Tausen Iskappe contains no ice from the last glaciation; i.e., the world's northernmost ice cap melted away during the post-glacial climatic optimum and was rebuilt when the climate got colder some 4000 years ago.
