A full holocene tephrochronology for the Kamchatsky Peninsula region: Applications from Kamchatka to North America

Autor: Tatiana K. Pinegina, Vera Ponomareva, Egor Zelenin, A. Kozhurin, Joanne Bourgeois, I. Florin Pendea, Maxim Portnyagin

Publikováno v: Quaternary Science Reviews. 168:101-122

Geochemically fingerprinted widespread tephra layers serve as excellent marker horizons which can directly link and synchronize disparate sedimentary archives and be used for dating various deposits related to climate shifts, faulting events, tsunami

Prehistoric human responses to volcanic tephra fall events in the Ust-Kamchatsk region, Kamchatka Peninsula (Kamchatsky Krai, Russian Federation) during the middle to late Holocene (6000–500 cal BP)

Autor: Dustin M. Keeler, I. Florin Pendea, Erika Ruhl, Hans Harmsen, Eva L. Hulse, Irina Yu Ponkratova, Ezra B.W. Zubrow, Gregory Korosec

Publikováno v: Quaternary International. 394:51-68

Prehistoric peoples in Kamchatka coped with recurrent volcanic tephra fall events during the middle to late Holocene. Recent data collected by the International Collaborative Circumpolar Archaeological Project (ICAAP) between 2009 and 2011 explores t

Potential Pitfalls of Pollen Dating

Autor: John Southon, I. Florin Pendea, Elisabeth Levac, Gail L. Chmura, Thomas Neulieb, Michael Lewis

Publikováno v: Radiocarbon (0033-8222) (Univ Arizona Dept Geosciences), 2013, Vol. 55, N. 2-3, P. 1142-1155

Pollen extracted from ocean and wetland sediments cored from the eastern Canadian Margin, James Bay region, and Atlantic provinces of Canada have been radiocarbon dated and results are reported here. Pollen dates from ocean sediments were compared wi

Calibration of pollen assemblages and carbon–nitrogen ratios to discriminate boreal wetland types

Autor: I. Florin Pendea, Gail L. Chmura

Publikováno v: Review of Palaeobotany and Palynology. 174:48-56

Differentiation of boreal wetlands in the palaeo record is required for studies of isostacy and sea level change, landscape change, and climate dynamics. To develop palynomorph signatures and calibrate soil C–N ratios for boreal wetlands we sampled

Early Holocene M~6 explosive eruption from Plosky volcanic massif (Kamchatka) and its tephra as a link between terrestrial and marine paleoenvironmental records

Autor: Joanne Bourgeois, I. Florin Pendea, Maxim Portnyagin, Vera Ponomareva, Alexander Derkachev, Paula J. Reimer, Dirk Nürnberg, Dieter Garbe-Schönberg, S. P. Krasheninnikov

Publikováno v: International Journal of Earth Sciences, 102 (6). pp. 1673-1699.

We report tephrochronological and geochemical data on early Holocene activity from Plosky volcanic massif in the Kliuchevskoi volcanic group, Kamchatka Peninsula. Explosive activity of this volcano lasted for ~1.5 kyr, produced a series of widely dis

High resolution record of carbon accumulation rates during boreal peatland initiation

Autor: I. Florin Pendea, G. L. Chmura

Boreal peatlands are a major global C sink, thus having important feedbacks to climate. A decreased concentration in atmospheric CO2 7000–10 000 years ago has been linked to variations in peatland C accumulation rates attributed to warm climate cha
