Andreas Thurnherr will present observations showing where and how AABW is transformed to lighter density classes and upwells and will also discuss how these two requirements for closing the overturning circulation relate to the observed vertical gradients in turbulence levels and to the hypothesized role of bottom boundary layers for upwelling of bottom water.
