SEA-RAFTED PUMICE AT MILI ATOLL, MARSHALL ISLANDS 3000km from Source

چکیده
Pumice pebbles were collected by staff of the Marshall Islands Historic Preservation Office (RMIHPO) during a 2005 cultural inventory of Jelbon Islet, Mili Atoll. GNS Science analyzed the major and trace element chemistry and found a close match with analyses of the alkali-rich rhyolite erupted in 1953-1957 from Tuluman Island, Admiralty group, Papua New Guinea some 3000 km from Mili Atoll. These findings highlight the importance of sourcing exotic raw materials in attempts to distinguish between human transport and drift by ocean currents.

Pumice rafting and faunal dispersion during 2001–2002 in the Southwest Pacific: record of a dacitic submarine explosive eruption from Tonga
A new influx of sea-rafted pumice reached the eastern coast of Australia in October 2002, approximately 1 year after a felsic, shallow-marine explosive eruption at a previously unknown volcano (0403-091) along the Tofua volcanic arc (Tonga). The eruption produced floating pumice rafts that first became stranded in Fiji in November 2001, approximately 1 month after the eruption. Strandings of se...
متن کاملMany Atolls May be Uninhabitable Within Decades Due to Climate Change
Observations show global sea level is rising due to climate change, with the highest rates in the tropical Pacific Ocean where many of the world's low-lying atolls are located. Sea-level rise is particularly critical for low-lying carbonate reef-lined atoll islands; these islands have limited land and water available for human habitation, water and food sources, and ecosystems that are vulnerab...

Radiation doses calculated for people resettling Bikini Island at Bikini Atoll, Enjebi Island at Enewetak Atoll, Rongelap Island at Rongelap Atoll, and Utrōk Island at Utrōk Atoll are presented. Residence is assumed to begin in 2010. In previous dose assessments it was shown that (137)Cs accounts for about 98% of the total dose for returning residents. About 85 to 90% (depending on the atoll) i...
متن کاملAtolls as Settlement Landscapes: Ujae, Marshall Islands By
Williamson and Sabath (1982) have demonstrated a significant relationship between modern population size and environment by examining atoll area and rainfall in the Marshall Islands. The present work seeks to extend that argument into prehistory by examining the relationship of ancient habitation sites and size of aroid pit agricultural systems to atoll land area and rainfall regime along the 1...
متن کاملA Comparative Study on 137 Cs Transfer from Soil to Vegetation in the Marshall Islands
The degree of 137 Cs root uptake into tropical fruits, vegetables and native foliage from coral atoll soils in the Marshall Islands has been quantified using soil-to-plant transfer factors. Transfer factor values for different plants on Bikini Island (Bikini Atoll) range between 0.2 and 144 and, in general, are considerably higher than those observed in continental soils. In this paper we will ...
