Hi,
Dust flux reconstructions from the late Quaternary consistently show that dust emissions from source areas around the world were a factor of 2-4 higher in glacial periods than in interglacials. Is this because dust source regions were systematically drier and have lower vegetation density during glacial periods? Is it because new dust sources developed on continental shelves exposed during sea level lowstands? Is it due to an increased supply of fine-grained sediments from glacial erosion? Or is it due to strengthened surface winds?
Thanks!
