Tritium/He-3 and O-18 Measurements During the ACYSYS Expedition 1996

SCHLOSSER, PETER LDEO-COLUMBIA university .作为世界气象组织计划的国际倡议ACSYS的一部分，研究者提议在德国研究船北极星号（Polarstern）的游轮上进行一项研究项目。他将在北冰洋东部进行氚、氦和氧的同位素测量，以确定大西洋水的范围，最近发现大西洋水比以前知道的要深入盆地。大西洋水向北极的扩张可能是气候变暖导致的全球变化的结果，也可能是与气候无关的因素导致的环流暂时变化的结果。这次航行收集的数据将填补北冰洋的一个重要空白，以便未来的研究可以在全球变化的背景下观察环流变化的持久性。

ABSTRACT OPP-9530795 SCHLOSSER, PETER LDEO-COLUMBIA UNIV. The investigator proposes to conduct a research project on a cruise aboard the German research vessel Polarstern as a part of the international initiative ACSYS planned by the World Meteorological Organization. He will make tritium, helium, and oxygen isotope measurements in the eastern Arctic Ocean to determine the extent of Atlantic water that has recently been found to extend much farther into the basin than previously known. The expansion of Atlantic water into the Arctic could be the result of global change in response to a warming climate or a temporary change in circulation due to factors not associated with climate. The data collected on this cruise will fill in an important gap in the Arctic Ocean so that future studies may observe the persistence of the change in circulation within a global change context.
