The concentrations of heavy metals (mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr), copper (Cu) and arsenic (As)) in surface water and sediments were investigated in two adjacent drinking water reservoirs (Hongfeng and Baihua Reservoirs) on the Yunnan-Guizhou Plateau in Southwest China. Possible pollution sources were identified by spatial and statistical analyses. For both reservoirs, Cd...

Abstract Accounting for temporal changes in carbon dioxide (CO 2 ) effluxes from freshwaters remains a challenge global and regional budgets. Here, we synthesize 171 site-months of flux measurements CO based on the eddy covariance method 13 lakes reservoirs Northern Hemisphere, quantify dynamics at multiple scales. We found pronounced sub-annual variability all sites. By accounting diel variati...

NEDO has developed MEPAS, a software for exploration of geothermal reservoir. MEPAS has bcen developed as a tool for geologists to analyze earthquakes and find fractures by comparing earthquakes with other exploration data. MEPAS consists of a seismic data processing part and a geological analysis part. The geological analysis part features 3D display, time and space distribution display, fract...

Remote sensing product uncertainties for phytoplankton chlorophyll-a (chla) concentration in oligotrophic and mesotrophic lakes reservoirs were characterised across 13 existing algorithms using an situ dataset of water constituent concentrations, inherent optical properties (IOPs) remote-sensing reflectance spectra Rrsλ collected from 53 (346 observations; chla < 10 mg m-3, median 2.5 m-3).
