Samstarfsverkefnu við Kevin Burton, Open University UK, um samsætur í íslenskum straumvötnum, tímakvarða efnaveðrunar, og tilraunir á rannsóknarstofu til þess að skilgreina breytingar á samsætuhlutföllum samfara upplausn basalts í vatni. (2004-2006) Fjármagnað af NERC (Náttúruvísindahluta Breska vísindasjóðsins) og Jarðvísindastofnun Háskólans (sjá ritlista SRG).

 		 Chemistry, discharge and suspended matter in rivers in the vicinity of River Skaftá, south eastern Iceland, (2002-2006). Work in cooperation with the Hydrological Section of the National Energy Authority, Iceland. The study is supported by Landsvirkjun.

Chemistry, discharge and suspended matter in rivers in the southern Lowlands, Iceland, (1996-2006). Work in cooperation with the Hydrological Section of the National Energy Authority, Iceland and the University of Stockholm, Sweden. The study is supported by Landsvirkjun and the Ministry of the Environment (see publication list).

Chemistry, discharge and suspended matter in rivers in north-western Iceland, (2004-2006). Work in cooperation with the Hydrological Section of the National Energy Authority, Iceland and the University of Stockholm, Sweden. The study is supported by the Ministry of the Environment and the National Energy Authority.

Continuous monitoring of rivers draining the Eyjafjallajökull and Mýrdalsjökull Glaciers, south-eastern Iceland, (1999-2006). Work in cooperation with the Hydrological Section of the National Energy Authority, Iceland. The study is supported by the Icelandic government because of possible volcanic eruptions within the glaciers.

Chemistry of precipitation on the Langjökull Glacier, Iceland (1996-2006). The study is supported by the Institute of Earth Sciences.

Dissolution rates and dissolution mechanism of volcanic glasses. Work in cooperation with Eric Oelkers, University of Paul Sabatier, Toulouse, France (1998-2006) and Domenic Wolff-Boenisch (see above). This study has been supported by the European Union, the Icelandic Research Council; RANNÍS, the Research Fund of the University of Iceland, the Science Institute and the Paul Sabatier University, Toulouse, France (see publication list).

River suspended matter fluxes resulting from adsorption/desorption from river suspended matter in seawater. Work in cooperation with Eric Oelkers and Oleg Pokrovsky, Paul Sabatier University, Toulouse, France (1999-2006). This study has been supported by the Icelandic Research Council; RANNÍS, the Science Institute and the Paul Sabatier University, Toulouse, France

The concentration, isotope composition and origin of sulphur in Icelandic river waters. Work in cooperation with Peter Torssander, University of Stockholm, Sweden (1998-2006). This research project has been supported by Landsvirkjun and the Icelandic Ministry for the Environment, and University of Stockholm, Sweden.

Os and U - isotopes in Icelandic river waters, dissolved and suspended matter. The timescale for weathering of Icelandic rocks has been studied, and isotope fractionation during dissolution of basalts, glassy and crystalline will be studied by experiments in the laboratory. Field and experimental work led by Kevin Burton, Open University UK, (2004-2006). This research project is supported by NERC and the Institute of Earth Sciences, University of Iceland.
