recommendations! Published in 2021 at "Limnology and Oceanography: Methods"

DOI: 10.1002/lom3.10443

Abstract: Paleolimnological reconstructions provide insights into hydrological variability of dynamic floodplain lakes. However, spatial and temporal integration of multiple reconstructions often remains underdeveloped because the efficacy of different paleolimnological measurements varies among lakes due to gradients… read more here.

DOI: 10.1016/j.jconhyd.2020.103658

Abstract: The rising food production to meet the growing human population has led to increased anthropogenic inputs of nutrients such as NO3- in groundwater and aquatic environments. Nitrate concentrations, hydrochemistry, and isotope data (δ18O-H2O, δ2H-H2O, 15N-NO3,… read more here.

DOI: 10.1017/jfm.2020.726

Abstract: Abstract The accurate prediction of turbulent mixing induced by Rayleigh–Taylor (R–T), Richtmyer–Meshkov (R–M) and Kelvin–Helmholtz (K–H) instabilities is very important in understanding natural phenomena and improving engineering applications. In applications, the prediction of mixing with… read more here.

DOI: 10.1109/lgrs.2019.2961502

Abstract: Endmember extraction (EE) is one important step in hyperspectral unmixing. However, some EE methods under pure-pixel assumption may work badly for highly mixed data due to the complexity of image data. In this work, we… read more here.
