The role of windblown dust from ephemeral river valleys in the fertilisation of the Benguela Upwelling System

Subtitle:
An investigation into the iron, phosphorus and nitrogen content of sediment and dust in Namibia’s ephemeral river valleys and the offshore phytoplanktonic response to aeolian dust deposition
Abstract:

The deposition of dust on the global ocean provides essential nutrients for biological primary production. Research into aeolian dust has focused on dust sources identified at the global scale by the emission of mineral aerosols a minimum of one kilometre into the atmosphere. The deflation origins of these global hot-spots of dust are major topographical pan features providing paleolacustrine sources of fine, desiccated sediment that is highly susceptible to wind erosion. However, small-sc...
