An optimal strategy for determining triple oxygen isotope ratios in natural water using a commercial cavity ring-down spectrometer
Triple oxygen isotope ratios have been increasingly acknowledged as useful hydrological tracers but measuring both 17O/16O and 18O/16O ratios with meaningful precision has been challenging due to the much lower n...

Evidence of air-snow mercury exchange recorded in the snowpack at Dome Fuji, Antarctica
Measuring the mercury content in shallow Antarctic snow pits is useful for understanding the mercury dynamics of the Antarctic Plateau and the global mercury cycle and for interpreting ice core data. We determ...

Hydrothermal alteration and isotopic variations of igneous rocks in Barton Peninsula, King George Island, Antarctica
O, H, S and Sr isotopes were investigated to characterize the nature of hydrothermal fluids and alteration processes in volcanic and intrusive rocks in Barton Peninsula, King George Island. The oxygen and hydr...

Glacier extent and volume change (1966∼2000) on the Su-lo Mountain in northeastern Tibetan Plateau, China
The topographic maps of 1:50, 000 scales, aerial photographs taken in 1966, one Landsat image taken in 1999, and SRTM data from 2000 were used to quantify the losses in area and volume of the glaciers on the S...

Origin of E-MORB in a fossil spreading center: the Antarctic-Phoenix Ridge, Drake Passage, Antarctica
The fossilized Antarctic-Phoenix Ridge (APR) with three segments (P1, P2, and P3), Drake Passage, is distant from the known hotspots, and consists of older N-MORB formed prior to the extinction of spreading an...

Geochemistry of volcanic rocks in Barton and Weaver peninsulas, King George Island, Antarctica: Implications for arc maturity and correlation with fossilized volcanic centers
We investigated geochemical characteristics of the Paleocene-Eocene volcanic rocks in Barton and Weaver peninsulas, King George Island, Antarctica. Volcanic rocks are predominantly tholeiitic, and show geochem...
