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. -

Coombs Building, ANU Distributed for the Department by: The Australian National University Press The Climate of Mt Wilhelm PREFACE In 1966, the Australian National University with assistance from the Bernice P. Bishop Museum, Hawaii, established a field station beside the lower Pindaunde Lake at an altitude of 3480 m on the south- east flank of Mt Wilhelm, the highest point in Papua New Guinea. The field station has been used by a number of workers in the natural sciences, many of whose publications are referred to later in this work. The present volume arises from observations made by three botanists and their collaborators when members of the Department of Biogeography and Geomorphology, during the course of their work on Mt Wilhelm while based on the ANU field station. It is the second in the Departmental series describing the environment and biota of the mountain, and will be followed by others dealing with different aspects of its natural history. -

CALENDARS by David Le Conte
CALENDARS by David Le Conte This article was published in two parts, in Sagittarius (the newsletter of La Société Guernesiaise Astronomy Section), in July/August and September/October 1997. It was based on a talk given by the author to the Astronomy Section on 20 May 1997. It has been slightly updated to the date of this transcript, December 2007. Part 1 What date is it? That depends on the calendar used:- Gregorian calendar: 1997 May 20 Julian calendar: 1997 May 7 Jewish calendar: 5757 Iyyar 13 Islamic Calendar: 1418 Muharaim 13 Persian Calendar: 1376 Ordibehesht 30 Chinese Calendar: Shengxiao (Ox) Xin-You 14 French Rev Calendar: 205, Décade I Mayan Calendar: Long count 12.19.4.3.4 tzolkin = 2 Kan; haab = 2 Zip Ethiopic Calendar: 1990 Genbot 13 Coptic Calendar: 1713 Bashans 12 Julian Day: 2450589 Modified Julian Date: 50589 Day number: 140 Julian Day at 8.00 pm BST: 2450589.292 First, let us note the difference between calendars and time-keeping. The calendar deals with intervals of at least one day, while time-keeping deals with intervals less than a day. Calendars are based on astronomical movements, but they are primarily for social rather than scientific purposes. They are intended to satisfy the needs of society, for example in matters such as: agriculture, hunting. migration, religious and civil events. However, it has also been said that they do provide a link between man and the cosmos. There are about 40 calendars now in use. and there are many historical ones. In this article we will consider six principal calendars still in use, relating them to their historical background and astronomical foundation. -

CONDUIT AND ERUPTION DYNAMICS OF THE 1912 VULCANIAN EXPLOSIONS AT NOVARUPTA, ALASKA A DISSERTATION SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI‘I AT MĀNOA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN GEOLOGY AND GEOPHYSICS December 2017 By Samantha Jo Isgett Dissertation Committee: Bruce F. Houghton, Chairperson Helge M. Gonnermann Christina Neal Thomas Shea John Allen © 2017, Samantha Jo Isgett ii Acknowledgements I probably would not be “standing here today” if my advisor Bruce Houghton had not introduced me to the wonderful world of volcanology. I entered his 300 level volcanology class as a naïve sophomore who had no ambitions of going to graduate school and left knowing that I wanted to be volcanologist and the steps that I needed to take to get there. Bruce has a passion not only for solving the big science question, but also in passing on his knowledge and skill-sets to his students. I cannot thank Bruce enough for seeing in me the potential makings of a scientist and guiding me there. It was, and always will be, a privilege to work with you. I would like to thank my committee — Helge Gonnermann, Thomas Shea, Christina Neal, and John Allen — for pushing me to take every problem and interpretation just a little (or a lot) further. I am especially grateful to Tom and John for stepping in at the last hour. Thank you all for your time and patience. Alain Burgisser, Laurent Arbaret, and Sarah Fagents also brought outside perspectives and skill-sets that were crucial for this project. -

Pompeii and Herculaneum: a Sourcebook Allows Readers to Form a Richer and More Diverse Picture of Urban Life on the Bay of Naples
POMPEII AND HERCULANEUM The original edition of Pompeii: A Sourcebook was a crucial resource for students of the site. Now updated to include material from Herculaneum, the neighbouring town also buried in the eruption of Vesuvius, Pompeii and Herculaneum: A Sourcebook allows readers to form a richer and more diverse picture of urban life on the Bay of Naples. Focusing upon inscriptions and ancient texts, it translates and sets into context a representative sample of the huge range of source material uncovered in these towns. From the labels on wine jars to scribbled insults, and from advertisements for gladiatorial contests to love poetry, the individual chapters explore the early history of Pompeii and Herculaneum, their destruction, leisure pursuits, politics, commerce, religion, the family and society. Information about Pompeii and Herculaneum from authors based in Rome is included, but the great majority of sources come from the cities themselves, written by their ordinary inhabitants – men and women, citizens and slaves. Incorporating the latest research and finds from the two cities and enhanced with more photographs, maps and plans, Pompeii and Herculaneum: A Sourcebook offers an invaluable resource for anyone studying or visiting the sites. Alison E. Cooley is Reader in Classics and Ancient History at the University of Warwick. Her recent publications include Pompeii. An Archaeological Site History (2003), a translation, edition and commentary of the Res Gestae Divi Augusti (2009), and The Cambridge Manual of Latin Epigraphy (2012). M.G.L. Cooley teaches Classics and is Head of Scholars at Warwick School. He is Chairman and General Editor of the LACTOR sourcebooks, and has edited three volumes in the series: The Age of Augustus (2003), Cicero’s Consulship Campaign (2009) and Tiberius to Nero (2011). -
