Erosional control on alkalinity release in a changing Arctic
Which influence the erosion rate exerts on the transport of alkalinity from the land to the ocean is one of the central, but so far largely unresolved questions. It is undisputed that the origin of alkalinity in the oceans is terrestrial erosion and weathering processes. It is equally undisputed tha...
