>> I came across this issue of ice free Arctic Ocean in context of the >> Independence I Culture of Greenland and the elevated beaches of the >> Independence Fjord in North West Greenland.
One Norwegian scientist wrote an article to the climate skeptics web site about it and claimed that the water-laden elevated huge sand beaches of the Independece Fjord are evidence of ice-free Arctic Ocean only some 7,000 years ago. She insists that the grounding marks of ice floes create rough and upturned seaside, not a neatly laden sandy beaches. In addition, the thin tents of the Independence I Culture of the area, are suggestive of warm climate. We are trying to package an expedition to the Independence Fjord to sample mud cores in front of these beaches. When the United Nations General Assembly was presented proposition UNGA101292 by the World Indigenous Nations Summit, we have suggested a Mega-Surtsey volcanic lava floods heating parts of the ocean extensively at times. In fact, the World Indigenous Nations Summits' plea to the UN General Assembly will, of necessity, stipulate an occurrence of massive subsea lava floods around Icelandic Seas if their chronologies of rapid ice age holds water. These produced localised warming events. As per the Independence Fjord, if there were a geothermally maintained volcanic jacuzzi east of Greenland, we try to obtain Apectodinium and Azolla fern deposits in front of the elevated sand beaches of the Independece Fjord which would appear there if ice age was caused by big sub sea lava floods (and Milutin Milankovic orbital forcing is put into coffin). There are many potential heat sources in Arctic Ocean that could have caused parts of the ocean to heat up in the past. But this kind of ice free ocean has nothing to do with climate, except that steam generated in the winter would be an excellenct snow cannon just like the Native Americans insist at the UN that the ice age was fast event and they recall it.
