Hydrochemical characteristics and sources of brines in the Gasikule salt lake, Northwest Qaidam Basin, China
hydrochemical characteristics origin of brines material source Gasikule salt lake Qaidam Basin
2017/4/10
The origin of the abundant salt resources in the Gasikule salt lake in the northwest Qaidam Basin in China remains
highly contested. We performed a detailed study of the hydrochemical characteristics...
Are existing drinking water sources safe from As contamination in Hanam province, Vietnam?
arsenic contamination Hanam province Vietnam rainwater safe drinking wate
2017/4/11
This study investigated arsenic (As) concentrations in existing drinking water sources in Hanam province, Vietnam.
Sand-filtered groundwater, piped water, raw groundwater, and a type of drinking wate...
Sources of pore water in a Tanegashima mud volcano inferred from chemical and stable isotopic studies
water chemistry mud volcano fluid migration clay mineral dehydration stable isotopic composition
2017/8/9
Pore waters at the depths of 0-590 cm below seafloor (bsf) were collected from four core samples at four different sites in a mud volcano off Tanegashima Island between Ryukyu trench and Ryukyu arc of...
Preliminary Identification of Ground-water Nitrate Sources Using Nitrogen and Carbon Stable Isotopes,Kansas
Preliminary Identification Ground-water Nitrate Sources Nitrogen and Carbon Stable Isotopes
2009/10/20
Increasing nitrate-N in ground water is a problem in many areas with limited ground-water supplies, such as west-central Kansas. However, potential sources of nitrate-N are not known. Nitrate-N concen...
Trace element and isotopic evidence for temporal changes of the mantle sources in the South Shetland Islands, Antarctica
trace elements Sr-Nd-Pb isotopes subduction component heterogeneous mantle South Shetland Islands
2017/8/10
We present Sr-Nd-Pb isotope data from the Paleocene-Eocene volcanic rocks in King George Island, South Shetland Islands, West Antarctica. The initial isotopic ratios of the analyzed samples display li...
High sensitivity measurements of nitrogen isotopic ratios in coral skeletons from Palau, western Pacific: Temporal resolution and seasonal variation of nitrogen sources
coral skeleton δ15N value δ18O value δ13C value seasonal variation
2017/8/10
By using a step-wise heating method in conjunction with static vacuum mass spectrometry, we have measured at high temporal resolution (one month) the nitrogen isotopic ratio of a coral skeletal sample...
