Radon, water chemistry and pollution check by volatile organic compounds in springs around Popocatepetl volcano, Mexic
soil radon water chemistry volcanic activity
2015/9/10
Popocatepetl volcano is a high-risk active volcano in Central Mexico where the highest population density in the country
is settled. Radon in the soil and groundwater together with water chemistry fr...
Water chemistry and soil radon survey at the Poas volcano (Costa Rica)
Poas volcano geochemistry radon precursor
2015/9/10
Radon-in-soil monitoring at the Poas volcano (Costa Rica) has been performed together with water chemistry
from the hot crater lake since 1981 and 1983 respectively. The results are discussed as a fu...

Resilience of pore-water chemistry and calcification in photosyntheticzones of calcifying sediments
Resilience of pore-water chemistry calcification in photosyntheticzones calcifying sediments
2014/4/16
Photosynthetically driven calcification was investigated in diatom-dominated carbonate sediments from Bait Reef, Australia. Laboratory measurements conducted over complete diel cycles, using O2, pH, C...
Animal Communities in Icelandic Rivers in Relation to Catchment Characteristics and Water Chemistry
Animal Communities Icelandic Rivers Catchment Characteristics Water Chemistry
2009/10/23
Catchment areas of Icelandic rivers are mostly barren or with little vegetation
cover in the highlands, but with heathland and mire vegetation in the lowlands.
Chemical composition and nutrient avai...
Water Chemistry and Bacterioplankton in Two Subalpine Rivers in Finnish Lapland
Water Chemistry Bacterioplankton Subalpine Rivers Finnish Lapland
2009/10/22
Water chemistry and bacterioplankton were analysed for two subalpine rivers,
River Kidisjoki and River Utsjoki, in northernmost Finland. The data set is
based on continuous runoff measurements and w...
Glacial effects on discharge, sediment load and water chemistry from a subarctic river basin
glacier permafrost sediment load water balance tank model rating curve
2009/7/14
The subarctic Tanana River basin, Alaska, is occupied by ca. 5.6% glacierized region and the other discontinuous permafrost region. Time series of discharge, suspended sediment concentration (SSC) and...
Trends and seasonality in stream water chemistry in two moorland catchments of the Upper River Wye, Plynlimon
stream water chemistry Upper River Wye moorland catchments
2009/6/8
Stream water chemistry in the Cyff and Gwy subcatchments within the headwaters of the River Wye has been monitored regularly since 1980. In the Gwy, which is a predominantly semi-natural grassland ca...
Incorporating landscape characteristics in a distance metric for interpolating between observations of stream water chemistry
stream water chemistry landscape characteristics
2009/5/6
Spatial patterns of water chemistry along stream networks can be quantified using synoptic or "snapshot" sampling. The basic idea is to sample stream water at many points over a relatively short perio...
Using official map data on topography, wetlands and vegetation cover for prediction of stream water chemistry in boreal headwater catchments
water chemistry dissolved organic carbon temporal resolution
2009/4/28
A large part of the spatial variation of stream water chemistry can be related to inputs from headwater streams. In order to understand and analyse the dominant processes taking place in small and het...
An Assessment of the potential impact of the Gothenburg Protocol on surface water chemistry using the dynamic MAGIC model at acid sensitive sites in the UK
acidification recovery model
2009/3/24
The MAGIC model has been systematically calibrated to 12 sites in the UK, which form part of the UK Acid Waters Monitoring Network, using best available data. The model successfully simulates observed...
Long-term changes in precipitation and stream water chemistry in small forest and moorland catchments at Beddgelert Forest, north Wales
acid deposition recovery clearfelling Beddgelert streams rainfall
2009/3/5
Changes in the chemistry of bulk precipitation and stream water between 1982 and 2000 are described for small moorland and forest catchments located within Beddgelert Forest in north Wales.

nitrate potassium aluminium magnesium North Atlantic Oscillation
2009/3/5
Analysis of winter stream chemistry data from the Afon Hafren in mid-Wales reveals links between stream chemistry and the North Atlantic Oscillation (NAO). K, Y, Al and dissolved organic carbon (DOC) ...
Synchrony in relationships between the North Atlantic Oscillation and water chemistry among Sweden’s largest lakes
North Atlantic Oscillation water chemistry Sweden's largest lakes
2014/5/19
The North Atlantic Oscillation (NAO) is commonly presented as an easy and reliable index that can be used to study climatic effects on aquatic ecosystems. Here, the NAO winter index (NAOW) was applied...
