Short Vita    List of Publications

My primary interest is in the study of ice cores with emphasis on paleoenvironmental and paleoclimatic reconstructions from seasonal to orbital time scale (100,000 years). I have participated to 10 major field programs in Antarctica (EPICA Dome C and Talos Dome) and at lower latitudes/high elevation in the European Alps (Colle Gnifetti, Mt. Ortles, Adamello), Peru (Quelccaya and Hualcan), Papua (Irian Jaya) and Tibetan plateau (Zangser and Guliya glacier). Over the years I have developed an interest in trace elements analysis in ice cores, with special focus on cosmic input of extraterrestrial material, trace elements geochemical cycles and their relation to past environmental changes such as, variations in climatic conditions and large-scale atmospheric transport. At The Ohio State University I have developed a lab for the determination of very low trace element concentrations in glacier ice by Inductively Coupled Plasma Sector Field Mass Spectrometry (ICP-SFMS). Here I use trace elements to reconstruct the sources of dust and pollutants deposited on the ice fields around the world during the past. Presently I’m focusing on ice core archives such as those in Kilimanjaro (Tanzania), the Himalayas and the Tibetan Plateau (China), Quelccaya (Peru), Taylor Glacier (Antarctica) and the European Alps (Mt. Ortles). Since 2009, I’m in fact leading an international program to study climatic and environmental changes on Mt. Ortles (South Tyrol, Italy) where four cores have been drilled during fall 2011 and an extensive educational outreach program has been established at Ortles.org.

M.S. (EE), Moscow Power Engineering Institute, 1975.

E-mail: zagorodnov.1@osu.edu

Phone: (614) 688-3932

More about Victor Zagorodnov:

Victor studies the hydro-thermal regime, and the structure of polar and sub-polar glaciers in the Eurasian Arctic. Data derived from deep ice cores were used to reconstruct climatic conditions on Svalbard and Severnaya Zemlaya during the last 4000 years. Currently Victor is preparing for a deep ice coring project on Graham Bell Island, Franz Jozef Land (Russia). It is anticipated that the paleoclimatic history from the new core will contribute to the completion of the Holocene history of the Eurasian Arctic. Victor is also developing new methods for continuous ice core analyses, ice core drilling and borehole logging. Victor has participated in over 20 expeditions in the Arctic and Antarctic as well as on numerous mountains glaciers in Russia, Africa, China and Bolivia. His thermal-alcohol drill system was used in May 2002 to recover a 460-meter long core to bedrock on the Bona-Churchill col in the Wrangell-St. Elias Mountains of southeastern Alaska.

More about Emilie Beaudon:

Dr. Beaudon is now leading the characterization of trace elements in the Puruogangri ice core (Tibetan Plateau) as part of the Third Pole Project led by Drs. Lonnie Thompson and Paolo Gabrielli. Puruogangri is climatologically of particular interest because of its location along the boundary between the monsoon-dominated southern region and the dry continental northern region of the Plateau. The core from the Puruogangri ice cap, spanning ~7000 years, may help assess the see-saw pattern of the Asian Monsoon and reveal whether trace metal contamination originating from the region south of Himalaya can cross the world’s highest mountain chain and subsequently affect the Tibetan Plateau.

Presently, his study focuses on reconstructing the past climate and environment over Indonesia region, in particular temperature and precipitation using stable isotopic ratio of oxygen and hydrogen, major ions, and dust concentration contained in Papua ice cores. In addition, the relationship between the reconstructed past climate with the ENSO variations and the monsoon systems in the tropical Pacific will be investigated. In summer 2010, Donaldi spent time in the field recovering the Papua ice cores and rain samples in Papua, Indonesia. Currently, Donaldi has worked with the Research and Development Center of Indonesia Meteorological, Climatological and Geophysical Agency (BMKG) since 2006.

Roberto Filippi

Former Visiting Scholar

M.S., Geology, Università di Padova

B.A., Geology, Università di Padova

More about Roberto Filippi:

It was his love of glaciers that brought Roberto Filippi to us, but it was also because of that love that we lost him. Roberto was a visiting Italian scholar at the Byrd Polar Research Center in the Ice Core Paleoclimatology Group from April 2009 until June 2010. During that period he was involved in a project that mapped the retreat of the Quelccaya ice cap (Peru) and the ice fields of Kilimanjaro (Tanzania). He also participated in ice-core drilling projects in the Cordillera Blanca (Peru) and in the Antarctic Peninsula. After his visit here, he returned to Italy and started to work at the European Academy of Bolzano, where he was involved in mapping the glaciers of the massive of Ortles-Cevedale.

On March 9, 2011 Roberto was hiking on a glacier on Mt. Blanc in the French-Italian Alps when he fell into a crevasse and was killed. He was 29 years old. Strongly motivated to reach his objectives, Roberto was very much appreciated at the Byrd Polar Research Center for his excellent attitude towards learning new techniques and for his invaluable support in the field. But most of all we will remember him for his outstanding kindness and attentiveness towards the people around him. Those who met him, however briefly, were certainly moved by the look of friendliness and sweetness in his eyes. During the year that Roberto was at the Byrd Polar Research Center he acquired many dear friends and colleagues who now mourn his passing and remember him with great fondness and love. A video in Roberto's memory can be found here.

More about Ninglian Wang:

Wang's research interests include paleoclimatic reconstruction from the chemical and physical properties preserved in ice cores, correlation between the solar activity and the Earth's climate, the relationship of climatic changes in different areas, glacier fluctuations and the impact on water resources. He has conducted ice core drilling programs on the Tibetan Plateau and participated in glacier-water resource programs in western China. He has participated in over 10 expeditions to the high mountains for glaciological field studies. His research investigations have lead to development of a statistical model of the steady-state response of a mountain glacier to climate change, and provided evidence for the existence of sunspot cycles during the Maunder Minimum. Wang has found that during the Last Glacial Maximum the amplitude of the temperature decrease becomes enhanced with increasing altitude in the equatorial regions, and that the concentration of nitrate in the Guliya ice core from the Tibetan Plateau is positively correlated with solar activity.

More about Karl Philipoff:

Karl joined the Ice Core Paleoclimatology Group in September 2011 as a Masters student and was the recipient of a University Fellowship. His undergraduate research focused on the recovery of the Arctic boundary layer ozone concentrations after tropospheric ozone depletion events. His current research interests include determining the important influences on tropical glacier stable isotopic variations in a monsoon-dominated climate regimes through the examination of the Dasuopu ice core and corals from the Indian and Pacific Oceans.

More about Giuliano Bertagna:

Giuliano joined the ice core paleoclimate group in September 2014 as a visiting scholar. He is working on a two-years project that focuses on the Ortles ice cores that were recovered in the eastern European Alps by this group during 2011. By analyzing the Ortles ice cores, the goal is to study the past climatic and environmental changes at high elevation in South Tyrol, Italy, during the last centuries. He is also working on the development of a continuous flow analysis setup for ice cores by means of a melter system and an ICP-SFMS.
