“…To correct 14 C dates derived from bulk-sediment that may have been contaminated with old carbon, we calculated the reservoir offset by associating the 14 C age with 210 Pb ages and mean ages for tephra beds extracted from the same depth interval. The mineralogical and geochemical details of these tephras were previously studied to determine their sources and refine their chronology based on past geological and palaeoenvironmental events (Haberle 1998; Coulter et al 2009; Schneider et al 2017; Blong et al 2016, 2017a, 2017b). Tibito tephra dates ca.…”

We examined the radiocarbon (14C) reservoir effect in Lake Kutubu using tephrochronology and terrestrial plant material to deliver a precise age-depth profile and sedimentation rates for this lake. Based on the presence of two tephra horizons (Tibito and Olgaboli), we found a reservoir age offset in sediments of between 1490 and 2280 14C yr using the sediment ages derived from the lead-210 (210Pb) dating method. The live submerged biological samples collected exhibited a higher reservoir age offset than the sediment. This is most likely a result of delayed transport of “bomb” 14C from the atmosphere to aquatic and sedimentary system. The 14C reservoir effect increased with distance from the lake inlet and also decreased with depth. Dissolution of 14C-depleted carbon from surrounding limestone and direct in-wash of old soil or vegetation remnants from the catchment are the most likely causes of the 14C reservoir effect. Based on limestone areas mapped in Papua New Guinea, we indicate lakes which may be subject to a significant 14C reservoir effect. The results of this study demonstrate the magnitude of the 14C reservoir effect in lakes and provide insights to the correct interpretation of past environmental and archaeological events in PNG.

“…Using this new model, the estimated age was revised to around AD 1800. That age also was shown to be too young, as a profile of the island sketched in 1700 by the English sea captain William Dampier almost certainly of the coast of Long Island in the early 1700s clearly postdated the caldera created during ejection of the ash (see, for example, Blong, Kemp and Chen 2016). Detailed measurements on each sample in the newly established Radiometric Dating Laboratory at the University of Liverpool confirmed that the age of the ash lay beyond the reach of 210 Pb dating.…”

Terra Australis reports the results of archaeological and related research within the south and east of Asia, though mainly Australia, New Guinea and Island Melanesia -lands that remained terra australis incognita to generations of prehistorians. Its subject is the settlement of the diverse environments in this isolated quarter of the globe by peoples who have maintained their discrete and traditional ways of life into the recent recorded or remembered past and at times into the observable present.

In 1665 Athanasius Kircher included a short paragraph in his Mundus Subterraneus about a flamy spire and the collapse and disappearance of a high mountain following a 'horrible earthquake' on Timor in 1638. Although Timor has been known to have no volcanoes for at least the last century, Kircher's story has been repeated for 350 years, generally without acknowledgement, and often with the addition of embellishments and/or errors. This study traces the various accounts and the ways in which the story has morphed, particularly in the early 19 th century, when the emphasis in Kircher's story changes from a 'flamy spire', a 'horrible earthquake', and the collapse of the volcano into a continuing Stromboli-like eruption with no mention of an earthquake. Strangely, the fiction that the flamy spire could be seen from a distance of 300 miles is maintained and other embellishments added up to the present day.
