NEWS from BASENET working group

A novel paper by Chalov et al. (2020) presents the fate of river-borne chemicals under control by changing flow conditions. The study which is based on the novel approach and combines together sampling and acoustic Doppler current proﬁler (ADCP) water velocity transects, allows to accurately estimate the depth-integrated instantaneous chemicals ﬂux. Chalov, S.; Moreido, V.; … Continue reading NEWS from BASENET working group

Thermodynamic approach for remote mapping of forest ecosystem disturbance and accumulated ecological losses

Text by Dr. Viktor .I. Gornyy, Laboratory Head. Scientific-Research Centre for Ecological Safety (SRCES), Russian Academy of Sciences (RAS), Saint-Petersburg, Russia One of the most actual environmental safety problems is finding an integral index, characterizing the health of forest ecosystems at a quantitative level. It has been hypothesized that such an index may be based … Continue reading Thermodynamic approach for remote mapping of forest ecosystem disturbance and accumulated ecological losses

Data mining and machine learning to enhance data analysis for atmospheric science research

by: Martha Arbayani Zaidan The scientific media is brimming with Artificial Intelligence related buzzwords such as data mining and machine learning. But what do these terms really mean? And can we put these techniques to work in our own research? Data mining can be defined as the process of analysing hidden patterns of data to … Continue reading Data mining and machine learning to enhance data analysis for atmospheric science research
