Two mass spectrometers (MS) are tested for the measurement of volatile substances, such as hydrocarbons and metabolic gases, in natural waters. KOALA is a backpackable MS operated from above the water surface, in which samples are pumped through a fl

We describe a system for the semi-autonomous in situ measurement of lake chemical properties, with high temporal resolution and the potential to map chemical properties in 3 dimensions. The system comprises both fixed sensor locations on moored buoys

Between 1990 and 1999, SO4(2-) deposition in northern Sweden decreased by over 50%. To determine if a corresponding amelioration of stream acidity has occurred, we analyzed trends in anthropogenically driven episodic acidification in five streams dur
