water quality slope data of Co Ngoin Lake (2017)
  • 2019-05-28
  • 0
  • 1

The data set includes the vertical profile of water quality and the multi-parameter data of surface water quality of Selincho Lake during the investigation of the sources of rivers and lakes from June to July of 2017. The main water quality parameters measured are dissolved oxygen, conductivity, pH, water temperature, etc. YSI EXO2 water quality multi-parameter measuring instrument is calibrated according to lake surface elevation and local pressure before each measurement. The time interval of measurement is set at 0.25s, and the speed of putting in is slow, so he high continuity of data acquisition is guaranteed. The original data obtained include the measured data exposed to air above the water surface, which are eliminated in the later processing.

  • 1

This dataset contains the sequence data of the lake core TOC, CaCO₃, particle size and environmental magnetism parameters from 600 years to 1998 of Yamdrog Yumtso in the southern part of the Tibetan Plateau. It is used to study the environmental changes in the Yamdrog Yumtso region in the 1400 years. This data set is obtained from laboratory measurements. The data are obtained immediately after the completion of the instrument or experiment. The samples and data are collected in strict accordance with relevant operating procedures at all stages and comply with the laboratory operating standards. The TOC analysis is undertaken by a CS-344 analyzer, The CaCO₃ content is measured by the general chemical method, the particle size is measured with a Malvern Mastersizer 2000 laser particle sizer, and the environmental magnetism parameters are measured with a Kappa Bridge, DIGICO magnetometer and superconducting magnetometer. The rock core was collected from Chen Co Lake in the Yamdrog Yumtso Basin in the southern part of the Tibetan Plateau; the approximate sampling location is 90.49E, 28.93N, and the lake’s elevation is 4420 m.

  • 1

This is the water quality multi-parameter data set of Ngangla Ringco Lake during the River and Lake Source Investigation in 2017. It is used to acquire basic physical and chemical indices of lakes. And it can prepare for the following modern observation studies of lakes. The data observed dates from August 29, 2017 to August 30, 2017. It is measured by the YSI EXO2 multi-parameter water quality instrument. Instrument calibration is made before each measurement based on the altitude of the lake and the local pressure. The measuring interval is 0.25s. To ensure the data is frequently and continuously acquired, the instrument is slowly released. The original data includes data measured above the water surface, which is exposed to the air, and it has all been eliminated in the post processing. The data is stored as an excel file.
