To date, there are very few studies about the spectroscopy of lithium-containing minerals (LCMs) in the scientific community. The main objective of this study is to investigate the capability of Sentinel-2 image and FieldSpec3 spectro-radiometer in terms of mapping five important LCMs, including spodumene, lepidolite, amblygonite, petalite, and eucryptite. Therefore, first the FieldSpec3 spectro-r...... hiện toàn bộ
The hydrosocial cycle in rapidly urbanizing watershedsFrontiers of Earth Science - Tập 14 - Trang 256-267 - 2020
Melinda Laituri
Water is the essential resource of the 21st century where innovative water management strategies are needed to improve water security. This paper examines three case studies that exemplify the global water crisis, situated in rapidly urbanizing watersheds: Nairobi River Basin, Kenya; Citarum River Basin, Indonesia; and Addis Ababa River Basin, Ethiopia. Each of these watersheds are implementing la...... hiện toàn bộ
Water-related disasters: A review and commentaryFrontiers of Earth Science - - 2011
Walter M. Grayman
The purpose of this paper is to explore the nature of water-related disasters, look at the trends in water-related disasters, categorize water-related disasters in several dimensions, provide insights on the impacts of such disasters and discuss the predictability of disasters. Disasters may be succinctly defined as natural or human events, usually unexpected, that result in significant impacts in...... hiện toàn bộ
An unsupervised learning approach to study synchroneity of past events in the South China SeaFrontiers of Earth Science - Tập 13 - Trang 628-640 - 2019

Unsupervised machine learning methods were applied on multivariate geophysical and geochemical datasets of ocean floor sediment cores collected from the South China Sea. The well-preserved and continuous core samples comprising high resolution Cenozoic sediment records enable scientists to carry out paleoenvironment studies in detail. Bayesian age-depth chronological models constructed from biostr...... hiện toàn bộ
