Hydrochemical changes before and after earthquakes have been reported for over 50years. However, few reports provide sufficient data for an association to be verified statistically. Also, no mechan ...

Chemical analysis of groundwater samples collected from a borehole at Hafralaekur, northern Iceland, from October 2008 to June 2015 revealed (1) a long-term decrease in concentration of Si and Na and (2) an abrupt increase in concentration of Na befo

Precursor events to earthquakes are rarely reproduced. Measurement of groundwater chemistry in Iceland between 2008 and 2013 reveals distinct changes prior to two consecutive >M5 earthquakes.

We tested the hypothesis that reservoirs with low water residence time and autochthonous production influence river biogeochemistry in eutrophied river systems draining cultivated watersheds. The effect of a single artificial water reservoir and cons

Nitrogen fixation ( 15 N 2 -tracer method) by filamentous cyanobacteria and the flux of the newly fixed nitrogen into picoplanktonic organisms were investigated during three cruises in the central Baltic Sea in July and August 1995 and July 1996. The
