with volume but their ability to transport scales with their surface area.
The ice rafting of sedimentary material from the edges to the center of the
basin and its effect on primary production represent a unique biogeochemical
pathway connecting physical, chemical and biological processes. The suscep-
tibility of this transport route to future perturbations of Arctic climatology is
unknown. However, it seems that any change that resulted in the dimunition
