Kosipe Revisited
Peat in the mountains of New Guinea G.S. Hope Department of Archaeology and Natural History, Australian National University, Canberra, Australia _______________________________________________________________________________________ SUMMARY Peatlands are common in montane areas above 1,000 m in New Guinea and become extensive above 3,000 m in the subalpine zone. In the montane mires, swamp forests and grass or sedge fens predominate on swampy valley bottoms. These mires may be 4–8 m in depth and up to 30,000 years in age. In Papua New Guinea (PNG) there is about 2,250 km2 of montane peatland, and Papua Province (the Indonesian western half of the island) probably contains much more. Above 3,000 m, peat soils form under blanket bog on slopes as well as on valley floors. Vegetation types include cushion bog, grass bog and sedge fen. Typical peat depths are 0.5‒1 m on slopes, but valley floors and hollows contain up to 10 m of peat. The estimated total extent of mountain peatland is 14,800 km2 with 5,965 km2 in PNG and about 8,800 km2 in Papua Province. The stratigraphy, age structure and vegetation histories of 45 peatland or organic limnic sites above 750 m have been investigated since 1965. These record major vegetation shifts at 28,000, 17,000‒14,000 and 9,000 years ago and a variable history of human disturbance from 14,000 years ago with extensive clearance by the mid- Holocene at some sites. While montane peatlands were important agricultural centres in the Holocene, the introduction of new dryland crops has resulted in the abandonment of some peatlands in the last few centuries. -

There is now compelling evidence that microbially mediated reactions impart a significant effect upon the dynamics, composition, and abundance of nutrients in glacial melt water. Consequently, we must now consider ice masses as ecosystem habitats in their own right and address their diversity, functional potential, and activity as part of alpine and polar environments. Although such research is already underway, its fragmentary nature provides little basis for developing modern concepts of glacier ecology. This paper therefore provides a much-needed framework for development by reviewing the physical, biogeochemical, and microbiological characteristics of microbial habitats that have been identified within glaciers and ice sheets. Two key glacial ecosystems emerge, one inhabiting the glacier surface (the supraglacial ecosystem) and one at the ice-bed interface (the subglacial ecosystem). -
Give and Take Papua New Guinea Place Unusual Emphasis on the Sovereignty of the Individual
The Wola people of the Highlands of Give and Take Papua New Guinea place unusual emphasis on the sovereignty of the individual. Their society places few constraints on its members; they have no government, no Exchange in Wola Society authoritative leaders, no formal judicial system. If to paraphrase Rousseau, man is born free but is everywhere in chains, Wola man is very lightly shackled. Order in Wola Society is based on the exchange of wealth, the effect of an elaborate exchange system that allows the handing round of wealth—pearl shells, pigs and other, minor items. Exchange among the Wola is an important social principle. It requires co-operation and constrains the fractious individual to maintain an ordered society. This book presents a vigorous, new analysis of a Highlands people that is a substantial contribution both to the ethno graphy of the New Guinea Highlands and to anthropological theory.

Az igazság pedig nem is áll olyan messze a képzeltünkben élő Pápuáról: a Földünk második legnagyobb szigetén fekvő ország messze az egyik legkevésbé felfedezett része világunknak, mint földrajzi, mint pedig kulturális értelemben. Erre, az európai utazók által alig ismert szigetre mindent kétséget kizáróan életre szóló élmény jelent eljutni, ezért utunkat úgy állítottuk össze, hogy a "Volcanic 7 Summits” csoporthoz tartozó Mount Giluwe vulkánjának megmászása mellett további élmények is várjanak csapatunkra. Belekóstolunk a hegyvidéki területek apró falvainak különös világába, átélhetünk egy hamisítatlan tradicionális fesztivált, kitérünk a tengerparti régió érintetlen szigeteire, majd felfedezzük a Sepik folyó misztikus világát is. Utunk végére pedig nem marad más hátra, mint a mérvadó utazási oldalakon a régió gyöngyszemeként emlegetett Raja Ampat szigetvilága. Új-Guinea szigetének így az indonéz részéről is kapunk egy ízelítőt, hogy végül paradicsomi körülmények között pihenjük ki életünk egyik legnagyobb kalandját.Kiemelt látnivalók az utunk során:- a Mount Hagent körülvevő pápuai hegyvidék,- Ausztrália és Óciánia legmagasabb vulkánja, a Mt Giluwe,- a ország egyik leghíresebb kulturális fesztiválja, a két napos Hagen Show,- Új-Guinea leghosszabb folyója, a misztikus Sepik folyó,- a folyóparton élő pápuai törzsek, szellemházaik és különös szokásaik,- a Muschu-sziget meseszép tengerpartjai és japán háborús emlékei,- a Sentani-tó csodás panorámája a MacArthur emlékműről,- Raja Ampat paradicsomi szigetei,- a világ egyik leggazdagabb víz alatti élővilága. A "Volcanic 7 Summits” (v7s) kifejezés a hét kontinens hét legmagasabb vulkánját foglalja magába. -

QUARTER (with colored map) by B.H. BAKER, B.Sc., F.G.S. Geologist (Commissioner of Mines and Geology) First print 1967 Reprint 2007 GEOLOGYGEOLOGY OF THE MOUNT KENYA AREA DEGREE SHEET 44 N.W.NW. QUARTER (with colored map) by B.H. BAKER, B.Sc., F.G.S. Geologist (Commissioner of Mines and Geology) FOREWORD The geological survey of the area around Mt. Kenya, a dissected volcano which forms Kenya’s highest mountain, took a total of nine months field work, during which time Mr. Baker worked from camps which varied in altitude from below 5,000 ft. on the Equator to above the snow line. While the mountain had been visited by explorers, scientists and mountaineers on many occasions since 1887 (the summit was not climbed until 1899), the geology of the mountain was known in only the sketchiest detail before the present survey. The author here presents a complete picture of the geology, and deduces from the evidence of the stratigraphic column the history of the mountain from its beginnings in late Pliocene times. Of particular interest is an account of the glaciology of the mountain, in which is des- cribed each of the ten dwindling glaciers which still remain and the numerous moraines of these and earlier glaciers. Mr. Baker also shows that Mt. Kenya was formerly covered by an ice cap 400 sq. kms. in area, and that the present glaciers are the remnants of this ice cap. -
