    Reliable Ultra Trace Analysis of Cd, U and Zn Concentrations in Greenland Snow and Ice by Using Ultraclean Methods for Contamination Control

    by Changhee Han, Heejin Hwang, Jung-Ho Kang, Sang-Bum Hong, Yeongcheol Han, Khanghyun Lee, Soon Do Hur, Sungmin Hong

    This study presents ultraclean procedures used in the challenging task of determining trace elements at or below the pg/g concentration level encountered in Greenland snow and ice. In order to validate these ultraclean procedures, recent snowfall and Holocene ice from northwest Greenland were analyzed for Cd, U, and Zn concentrations. The total procedural blanks brought through the entire measurement procedure proved to be negligible, compared to trace element concentrations, measured in snow and ice samples. This validates the overall practicality of the proposed ultraclean procedures, thereby ensuring the reliable measurements of ultra-trace analysis. A comparison between our study and published data shows that improper procedures employed throughout all stages, from field sampling to analysis to elevate the concentrations by several orders of magnitude, relative to the reliable concentration ranges. The risk of contamination exposure for selected trace elements appears to increase in the order of U < As ≤ Pb < Cd < Zn. Reliable measurements of Cd, U, and Zn concentrations in snow and ice allowed us to interpret the data in terms of seasonal variations in the inputs of crustal and anthropogenic sources to Greenland ice sheet.

  • Electrical Conductivity Characteristics of a Shallow Ice Core from GV7, East Antarctica

    빙하코어의 전기 전도도는 주로 얼음의 산성도에 의하여 결정되는 것으로 알려져 있다. 빙하코어의 산성도를 두드러지게 증가시키는 대표적인 물질로는 화산활동에 의해 대기로 방출된 H2SO4, HNO3, HCl, HF가 있다. 따라서 전기 전도도 측정법(electrical conductivity measurement, ECM)을 빙하코어에 적용하였을 때 관찰되는 뚜렷한 피크들은 과거 화산활동을 지시할 수 있다. 만일 분출 시기가 알려진 화산 활동이 확인된다면 이를 빙하코어의 연대측정에 활용할 수 있다. 본 연구에서는 2013-2014년 남극 하계 시기에 한-이태리 공동시추 프로그램을 통하여 동남극 GV7(70°41"S, 158°51"E) 지점에서 획득한 78 m 천부 빙하코어의 전기 전도도를 깊이에 따라 측정하였고 그 변동 원인에 대하여 논하였다. 총 203년의 기록을 가지는 것으로 추정되는 이 빙하코어로부터 Pinatubo (1991), Tarawera (1886), Krakatau (1883), Coseguina (1835), Galungung (1822), Tambora (1815) 화산 분출물이 초래한 전기 전도도 증가를 관찰하였다. 코어 하부 일부 구간에서 관찰되는 전기 전도도와 물안정동위원소비 사이의 상관성은 산성물질 침적이 계절성을 갖는 것을 시사한다. 이 외에도, 빙하코어의 전기 전도도는 코어 상부로부터 임계밀도에 이르는 깊이까지 점차 증가하였다. 전기 전도도에서 관찰되는 화산활동 기록, 계절적 변동 특성, 전기전도도-밀도 사이의 상관관계는 전기 전도도 측정이 빙하코어의 깊이-연대관계, 물리적, 화학적 특성을 이해하는 데 유용한 방법임을 보여준다.

    Trace elements and Pb isotope records in Dome C (East Antarctica) ice over the past 800,000 years

    Trace elements (V, Cr, Mn, Fe, Co, Cu, Zn, As, Rb, Sr, Mo, Cd, Sb, Ba, Tl, Pb, Bi, Th and U) and Pb isotopic compositions from the EPICA (European Project for Ice Coring in Antarctica) Dome C ice core have been determined using inductively coupled plasma sector field mass spectrometry (ICP-SFMS) and thermal ionization mass spectrometry (TIMS), covering the period from ~533 kyr BP to ~800 kyr BP, respectively. Our data have enabled us to extend the previous EDC records of trace elements and Pb isotopes from the Holocene back to the Marine Isotopic Stage 20.2, ~800 kyr BP. We here discuss the EDC records of Ba, Rb, Mo, Sb, Cd, Tl, Bi and Pb isotopes. Crustal elements such as Ba and Rb show well defined variations in concentrations in relation to climatic conditions with lower values during the interglacial periods and much higher values during the coldest periods of the last eight climatic cycles. Volcanogenic Cd, Tl and Bi show a less pronounced relationship between concentrations and climatic conditions. The isotopic signatures of Pb suggest that changes in the provenance of dust reaching the East Antarctic Plateau from Potential Source Areas occurred during the interglacial periods before the MBE. Our data suggest that the main factors affecting deposition fluxes and sources of natural trace elements over Antarctica are most likely linked to a progressive coupling of the climates of Antarctica and lower latitudes over the past 800 kyr.
