The possibility to reconstruct BWT histories with sufficient resolution creates the potential for transects of such measurements across climatologically important gateways such as the Reykjanes Ridge. To reconstruct BWT histories at Site 642. How large have these variations been? How far back in time can we reliably estimate BWT histories? To isolate perturbations in the subsurface temperature profile resulting from variations in BWT histories. Are observed temperature perturbations to the background thermal field in fact due to variations in BWT? Top of page \| Previous \| Next
