Record #164655:

Enhancement of glacial solute fluxes in the proglacial zone of a polythermal glacier / J.L. Wadham, R.J. Cooper, M. Tranter, R. Hodgkins.

Title: Enhancement of glacial solute fluxes in the proglacial zone of a polythermal glacier / J.L. Wadham, R.J. Cooper, M. Tranter, R. Hodgkins.
Author(s): Wadham, J. L.
Cooper, R. J.
Tranter, M.
Hodgkins, R.
Date: 2001.
In: Journal of Glaciology. (2001.), Vol. 47(158) (2001)
Abstract: Documents solute fluxes and chemical weathering rates in the proglacial zone of Finsterwalderbreen, Svalbard. Describes sampling methods and chemical analysis. Compares hydrochemistry of bulk meltwaters from three monitoring stations. Compares solute fluxes and weathering rates in proglacial zone with those in upstream environment and infers where and how solute is acquired in the proglacial zone. Finds much (3.3 times) higher geochemical reactivity in proglacial zone than in glacial zone. Attributes this primarily to chemical weathering of reactive material in the proglacial active layer. Lists reasons why solute fluxes and weathering rates may be unusually high, e.g., glacier's polythermal regime, a bedrock lithology with significant carbonate and sulphide content and relatively rapid recent retreats of terminus. Suggests that active layer does not draw down any CO₂ from the atmosphere.
